Introduction

The Catalyst 8540 multiservice switch router (MSR) is a 13-slot, modular chassis featuring dual, fault-tolerant, load-sharing AC or DC power supplies. The ATM switch router provides a 20-Gbps full-duplex nonblocking switch fabric with switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

The Catalyst 8540 CSR switch router belongs to a class of high-performance Layer 3 switch routers and is optimized for the campus LAN or the intranet. The Catalyst 8540 CSR switch router provides both wirespeed Ethernet routing and switching services.

System Requirements

This section describes the system requirements for Cisco IOS Release 12.0(28)W5(32) and includes the following sections:

Memory Requirements

Minimum Flash Memory Requirements

Release Names, Versions, and Part Numbers

Memory Requirements

The DRAM memory configuration is 256 MB, which is the default for the Catalyst 8540.

Minimum Flash Memory Requirements

Cisco IOS Release 12.0(28)W5(32) and later releases require a minimum of 16 MB of contiguous boot Flash memory. The Catalyst 8540 route processor now ships by default with a 16-MB boot Flash SIMM.

Earlier releases of the Catalyst 8540 switch router shipped with an 8-MB boot Flash SIMM. The 8-MB boot Flash SIMM is not large enough to store system images for Cisco IOS software releases 12.0(4a)W5(11a) and later.

To check that your system has a 16-MB boot Flash SIMM, enter the show hardware EXEC command. The part numbers for route processors with a default 16-MB boot Flash SIMM are as follows:

73-2644-06 Rev. A0 for the Catalyst 8540 MSR

73-3775-03 Rev. A0 for the Catalyst 8540 CSR

If you have an 8-MB boot Flash SIMM, and have no additional memory installed, we recommend that you order a spare Flash PC card programmed with the latest version of the system image, part number MEM-8540M-FLC20M=.

Alternatively, you can use one of the following options to accommodate the larger image:

Option 1—If you already have a Flash PC card, download the system image to the Flash PC card.


Note If you have a Smart Modular, Sharp, or Intel 2+ Flash PC card that was formatted using a Cisco IOS software release prior to 12.0(4a)W5(11a), reformat it with Cisco IOS Release 12.0(28)W5(32) before downloading the image (you might need to boot the image from a TFTP server to format the PC Flash card). Do not erase the system image on the boot Flash SIMM. If the procedure fails, you will need it to recover. (See caveat CSCdm47012 later in these release notes for more information.)


Then do the following:

Enter the config-register 0x2102 global configuration command to change the configuration register to boot from the Flash PC card, instead of booting from the system-code SIMM (default).


Note If you have a redundant route processor configuration, you need ROMMON image 12.0(4.6)W5(13) or later. See caveats CSCdm81581, CSCdm54297, and CSCdm43664, which are described later in these release notes, for more information.


Enter the boot system slot0:filename global configuration command to specify the system image to boot on the Flash PC card.

Enter the copy system:running-config nvram:startup-config privileged EXEC command to save the configuration changes to NVRAM.

An example follows:

Switch(config)# config-register 0x2102
EHSA:Syncing confreg: 256 to secondary
Switch(config)# boot system slot0:cat8540m-wp-mz.120-4a.W5.11a
Switch(config)# end
Switch# copy running-config startup-config

Option 2—Download the system image to a TFTP server and boot the system image from the TFTP server. Enter the boot system tftp filename ip-address global configuration command to boot the system image from the TFTP server, instead of booting from the system-code SIMM (default).

An example follows:

Switch(config)# boot system tftp cat8540m-wp-mz.120-4a.W5.11a 172.20.52.3

Note You can boot only the primary route processor from a TFTP server, not the secondary.



Note The boot ROM on the Catalyst 8540 can be field-upgraded with the reprogram command. For more information about upgrading the boot ROM, see the ATM Switch Router Command Reference.


For more information about downloading system images and changing the default boot image, refer to the "File Management" chapter of the Configuration Fundamentals Configuration Guide in the Cisco IOS software documentation set.

Hardware Supported

Table 1 and Table 2 list the hardware modules supported on the Catalyst 8540 in the Cisco IOS Release 12.0(28)W5(32). They also include the minimum software release requirements for the hardware.

Table 1 lists the hardware modules supported by the Catalyst 8540 MSR.

Table 2 lists the hardware modules supported by the Catalyst 8540 CSR.


Note Although minimum software versions are listed, we strongly recommend that you use the latest available software release for all Catalyst 8540 hardware.

Determining Your Software Release

To determine the version of Cisco IOS software currently running on the Catalyst 8540, log into the switch and use the show version privileged EXEC command. The following sample output is from the show version command. The version number is indicated on the second line:

Cisco Internetwork Operating System Software
IOS (tm) PNNI Software (cat8540m-WP-M), Version 12.0(28)W5(32)

Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

Other Firmware Code

Most of the port adapters and interface modules supported on the Catalyst 8540 have upgradable FPGA and functional images. The FPGA and functional images include caveat fixes, but in most cases, it is not necessary to upgrade. The release notes that describe the caveats from the functional images are available on the World Wide Web at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/l3sw/8540/rel_12_0/w5_6f/rel_note/fpga_rn/index.htm

For information describing the firmware update process, refer to the ATM Switch Router Software Configuration Guide.

Feature Set Tables

The Cisco IOS Release software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. Those features are listed by release number in the following tables:

Table 3Feature Sets Supported by the Catalyst 8540 MSR

Table 4Feature Sets Supported by the Catalyst 8540 CSR Part 1—Releases 12.0(28)W5(32) to 12.0(13)W5(19)

Table 5Feature Sets Supported by the Catalyst 8540 CSR Part 2—Releases 12.0(10)W5(18c) to 12.0(1a)W5(6f)


Note All Catalyst 8540 CSR features, other than ATM Uplink features, are also applicable to the Catalyst 8540 MSR.

Caveat Symptoms and Workarounds

This section contains a list of open and resolved caveats for the Cisco IOS software:

With some OC-12c single-mode fiber line modules, the link might fail after inserting the fiber cable. Make sure that the fiber cables are completely seated by pushing on the strain reliefs of the individual fibers until they click into place to complete the optical connection. In some cases, the small metal septum on the front panel of the transceiver obstructs the connection.

The maximum number of ELAN LES/BUS pairs supported is 10.

The Catalyst 8540 does not support Token Ring LANE.

The ATM router module does not support the Fast Simple Server Redundancy Protocol (FSSRP).

Open Caveats—Cisco IOS Release 12.0(28)W5(32)

CSCef95689

Symptom: On a Catalyst 8540 MSR switch connected to a third party switch over an IMA connection with only one active link a synchronization error might occur on the third party switch.

This problem does not appear on connections between Cisco equipment, if there are at least two links in the IMA group, or if the E1/T1 link is not an IMA connection. This is caused by delayed ICP cells on the Cisco side causing the synchronization error.

Workaround: Use two or more active links in the IMA group or use a single link without the IMA configuration.

CSCed33806

Symptom: On the Catalyst 8540 MSR a cross-connection PVC with a high VCI number cannot be created.

The following error message appears:

Switch(config)# interface atm 0/0/1
Switch(config-if)# atm pvc 16 12311 interface ATM0/0/0 16 12311
../c8540-atms5000/NP5500/NP55_token_mgmt.c 864: Out of ovc entries for msc 0
../c8540-atms5000/NP5500/NP55_conn_resources.c 208: Couldn't allocate ovc - msc 0
../c8540-atms5000/NP5500/NP55_connection.c 587: Couldn't allocate output side resources for msc 0
%connection creation fails: connection installation failure
On interface ATM0/0/1 (16/12311) - interface ATM0/0/0 (16/12311)
Switch# show debug

Generic ATM MMC:
ATM MMC ERRORS debugging is on
ATM Connection Management event debugging is on
ATM Connection Management error debugging is
switch#

Workaround: None.

CSCdv89300

Symptom: Two Catalyst 8500 switches are connected with only one level of PNNI hierarchy on one switch (level:56) and three levels on the other switch (levels:56,64 and 104) and the switches are at the same peer group at the highest level. There are 15 CBR shaped tunnels and 15 unshaped tunnels on the connecting link between the switches. In this situation, UBR soft-VCs are not set up between the switches when there are more than 10 CBR shaped tunnels configured on the link between the switches. Plus, memory is held up because of the soft-VC setup retries. Eventually the amount of memory held up inhibits you from executing certain commands.

Workaround: None.

CSCdv12317

Symptom: You might need to specify a minimum VPI on Catalyst 8500 switches when it is communicating with a Cisco Broadband Switch Module (BXM) Series switch. If you do not, a Soft PVC might not be torn down because the Virtual Switch Interface (VSI) on the BXM interface uses VPI 0.

Workaround: None.

CSCdv08899

Symptom: On the Catalyst 8540 MSR and LightStream 1010 platforms, the option to set loop timing on OC-12 ports is not available.

Workaround: None.

CSCdu63734

Symptom: Delay in IOS-SNMP replies.

Condition: The delay occurs whenever IOS-SNMP is queried on CiscoFlash MIB.

Workaround: None

CSCdr99167

Symptom: When the switch processor LED is red, cell loss occurs on insertion of standby switch processor.

Workaround: None.

CSCdr22770

Symptom: When using framing mode STM-16, the show controllers command might report the framing mode as invalid. This should not impact the network.

Workaround: None.

CSCdp94469

Symptom: Operation, administration, and maintenance (OAM) pings might not work after a route processor switchover.

Workaround: None.

CSCdp03166

Symptom: Modem access to the console port requires special settings.

The Catalyst 8540 provides support for connecting the modem to the console port. However, the following settings of the modem are required:

1. Enable auto answer mode.

2. Suppress result codes.

You can configure your modem by setting the DIP switches on the modem or by connecting the modem to terminal equipment. Refer to the user manual provided with your modem for the correct configuration information.

Please note there are no hardware flow control signals available on the console port, so the console port terminal characteristics should match the modem settings.

Workaround: None.

CSCdm80628

Symptom: A T1 CES interface does not send out a remote alarm indication (RAI) in the reverse direction upon detecting an alarm indication signal (AIS).

Workaround: None.

CSCdm36284

Symptom: The command show atm resources shows that the number of cells in the UBR queue in an MSC increases continuously but slowly.This happens when traffic is sent through a Catalyst 8540 MSR at close to line rate.

Workaround: None.

CSCdm32678

Symptom: During route processor switchover, LMI times out on peer interfaces.

The Catalyst 8540 requires about a minute to switch over. The Frame Relay interface might take about a minute before it can respond to any LMI activity.

Workaround: To prevent LMI timeouts on peer interfaces during switchover, configure an LMI timeout longer than the time it takes for the Catalyst 8540 route processor to switch over. Configure lmi-n392dce, lmi-n392dte, lmi-t392dce and lmi-n391dte on the Frame Relay interface so that LMI will not bring down the interface if no LMI activity is seen for about a minute.

CSCdm29939

Symptom: Srecord integrity checking is not adequate.

If all the Srecord lines are removed from a functional image file, the file is corrupted and causes problems if downloaded. The reprogram command Srecord integrity checking does not catch this problem.

Workaround: None.

CSCdm11864

Symptom: The switch router might detect discrepancies between the software configuration and the hardware after a route processor switchover.

Across a route processor switchover, if an outdated (older than and different from the running configuration) start-up configuration synchronization is applied, or if the latest running configuration synchronization fails, then discrepancies might exist between software data structures and hardware programming. Any PVCs are preserved.

Workaround: Use the copy running-config startup-config command before a route processor switchover.

CSCdk07378

Symptom: Funnel VCs can jeopardize quality of service (QoS) for guaranteed services.

The current multipoint-to-point funnel implementation can compromise the QoS guarantees of other connections (guaranteed services) when the application that created the funnel SVC malfunctions. For example, if the application were to transmit traffic on more than one leg of the funnel VC simultaneously, the rate scheduler on the output interface would oversubscribe and, potentially, affect the peak cell rate (PCR), sustained cell rate (SCR), and maximum cell rate (MaxCR) guarantees for other VCs on the interface.

Workaround: None.

CSCdj42967

Symptom: When memory is almost or completely exhausted and a soft PVC goes down, it might not come back up, leaving it in a releasing or inactive state.

Workaround: None.

CSCdj13565

Symptom: ATM RMON data collection is not supported on subinterfaces or tunnels.

The atm rmon collect command is accepted on hardware interfaces only; it is ignored on subinterfaces. SNMP and NVGEN support (through portSelTable) is not possible until the interfaces MIB (RFC 1573) entries are added for tunnel subinterfaces. ATM RMON counters for a hardware interface do not include any of the traffic through tunnels configured on the interface.

Workaround: None.

CSCdj10889

Symptom: The call attempt counters for PortSelectGroups might not count the outgoing calls on the NNI interfaces because of switch router crankback attempts. This might result in a discrepancy between the call attempt counters shown on Portselgroup representing the interface on which the call came in and the counters shown on the Portselgroup representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.

Workaround: None.

Resolved Caveats

CSCsa89515

Symptom: On a cat8540MSR configured with several network-clock-select commands, the output of show network-clocks command displays the actual state for the clock source as Locked and the state of the primary clock source as Unlockable.

Condition: This problem may occur when the system switches to the system clock and then back to its original clock source.

Workaround: In order to remove the problem, the unlockable clock source should be unconfigured and then reconfigured using the configuration commands:

8540(config)#no network-clock-select 1 ATMx/y/z

8540(config)#network-clock-select 1 ATMx/y/z

CSCin67939

Symptom: The wrong payload pattern in idle cells might be transmitted from DS-3 and E3 interfaces.

As per recommendation I.361 (of the ITU-T), the payload pattern of the idle cell is "01101010" or "0x6A". But in DS-3 and E3 interfaces of the Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switches, the payload pattern of the idle cell is set to "00000000" or "0x00". This is incorrect as per the ITU-T specification.

Some interoperability issues with other devices might appear if those devices expect only the "0x6A" pattern.

Workaround: None.

CSCin67191

Symptom: Using the show vc command displays garbage data for TVC(I) type interfaces with multiple leaves. Data for TVC(O) type interfaces with multiple leaves are displayed correctly.


Note There is no functionality impact.


Workaround: Use the show atm vc command instead of the show vc command.

CSCin67022

Symptom: A burst of noise on the physical link can cause the PNNI Hello for the link to stay in the down state on one end of the link and in the attempt state on the other end.

Workaround: Use the shutdown and no shutdown commands on the interface (or subinterface) to force the PNNI Hello to come up.

CSCin64542

Symptom: The input and output counters for the OC-12 interface display a huge value. This problem is seen with traffic running just after bootup or after performing a "clear counters" when traffic is flowing across the link. For example:

4294944186 packets input, 4293742466 bytes, 0 no buffer

Workaround: None.

CSCin63771

Symptom: The show NCDP sources command always displays "health: unknown" after configuration.

Workaround: None.

CSCin53048

Symptom: In certain situations, the 8-port Gigabit Ethernet front end input queue displays negative values. This has been seen with the TTL value of 1 only in the lab.

This issue is cosmetic and has no effect on the performance of the Catalyst 8540 switch or on the 8-port Gigabit Ethernet interface module.

Workaround: None.

CSCin46178

Symptom: After a switch processor switchover the input and output cells and the rate counters for IMA, CES, and OC-48 interfaces display incorrect values.

Workaround: None.

CSCin37548

Symptom: The following issues could be seen on the simultaneous execution of certain PNNI CLIs.

The switch reloads when:

a. Through a console session run the show atm pnni topology command and wait for the more prompt to appear. Next, through a Telnet session delete the lowest level node. Press the Space key on the console session.

b. Through a console session run the show atm pnni neighbor command and wait for the more prompt to appear. Next, through a Telnet session delete the lowest level node. Press the Space key on the console session.

c. Through a console session run the show atm pnni background routes admin-weight command and wait for the more prompt to appear. Next, through a Telnet session delete the lowest level node. Press the Space key on the console session.

d. Through a console session run the show atm pnni exp-path detail command and wait for the more prompt to appear. Through a Telnet session delete all the explicit paths. Press the Space key on the console session.

The following issues are also seen:

e. Through a console session run the show atm pnni topology detail command and wait for the more prompt to appear. Next, through a Telnet session delete the lowest level node. Pressing Space key on the console session causes spurious memory access.

f. Through a console session run the show atm pnni aggregation node border-detail exception-detail command and wait for the more prompt to appear. Next, through a Telnet session delete the lowest level node. Press the Space key on the console session. The output is not aborted gracefully.

g. Through a console session run the show atm pnni database command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Press the Space key on the console session. The output is not aborted gracefully.

h. Through a console session run the show atm pnni explicit-paths detail command and wait for the more prompt to appear. Through a Telnet session delete the lowest level node. Pressing the Space key on the console causes spurious memory access and tracebacks are seen.

Workaround: None.

CSCin36885

Symptom: On a Catalyst 8540 MSR, if an OC-3 interface is overbooked and configured with PVCs that consume more than 599 Mbps of bandwidth, during bootup these PVCs are lost from the running configuration.

The following error message appears during bootup for every PVC that is rejected.

%connection creation fails: specified traffic/resource parameters are invalid

Workaround: Configure the PVCs that were lost once the switch boots up.

CSCin21738

Symptom: If the BITS port in T1 mode is the primary clock and it changes to "unlockable", the clock switches to the next priority clock but does not revert to the BITS port even when it is reconfigured correctly.

Workaround: Reconfigure the BITS clock source as in the following example:

switch(config)# no network-clock-select 1 BITS 0
switch(config)# network-clock-select 1 BITS 0

CSCin14721

Symptom: The CBR interface module sends a "remote alarm" to the peer interface if the line flaps continuously. This causes the peer interface to change to "yellow alarm" state.

Workaround: Enter the shutdown and no shutdown commands on the CBR interface.

CSCin13787

Symptom: When bursty traffic is sent to the ARM via a carrier module installed 1-port OC-12 interface module in a peer Catalyst 8540 MSR, the ARM interface displays underruns and drops packets.

Workaround: None.

CSCin13430

Symptom: A memory leak might occur during an "atmSoft_timerProcess". With every "soft-vc" retry the holding memory on "atmsig CC" and "atm soft CV timer" increases and the "free" memory decreases. The free memory might fall to as low as 700K at times.

Workaround: None.

CSCin13076

Symptom: The redundancy manual sync running config command does not synchronize the running-configuration files if the sync running config command is disabled at the "Switch(config-r-mc)#" configuration level.

Workaround: Use the automatic sync running config command by enabling it at the "Switch(config-r-mc)#" mode. For example:

Switch(config-r-mc)# sync config running

CSCin12950

Symptom: Packets received with a destination multicast MAC address and destination unicast IP address are forwarded to the Route Processor, which in turn forwards it like any normal IP packet

Workaround: None.

CSCin12494

Symptom: The switch might reload if the show atm snoop-vc EXEC command is entered after an inverse multiplexing over ATM (IMA) interface that is being snooped is deleted.

Workaround: None.

CSCin07783

Symptom: A fully utilized IMA group with eight E1 links is configured between two switches. The eight soft-VCs each use the resources offered by an E1 link. When traffic is flowing across the links and three of the links of the IMA group on one switch are shut down, traffic stops flowing through all soft-VCs. Then, soon after, the three links are shut down. Then all soft-VCs shut down and none of the VCs come up again.They remain in the NOT CONNECTED state.

Workaround: None.

CSCin07232

Symptom: The console freezes when the OC-12 interface is used as a snoop test port.

Workaround: None.

CSCin06931

Symptom: When you delete well-known VCs using the atm manual-well-known-vc delete command on a snooped interface and then execute a show snoop-vc command, the switch reloads.

Workaround: None.

CSCin04617

Symptom: On the Catalyst 8540, Catalyst 8510 MSR, and the LightStream 1010 switch, Frame Relay traffic stops flowing through previously configured PVCs when you reload the image or reboot the switch. However, the VC appears up.

Workaround: None.

CSCin03290

Symptom: The ATM uplink interface module on the Catalyst 8540 CSR sends multicast packets in 1483 bridge PDU format.

Workaround: None.

CSCin03109

Symptom: If tag-switching is disabled on an interface being snooped and a show atm snoop-vc command is executed, the switch reloads.

Workaround: None.

CSCin01661

Symptom: When the VCI range for tag switching is configured on an ATM interface, these VCI values are not reused when a new bind request is received.

Workaround: Disable and reenable tag switching on ATM interface.

CSCin01222

Symptom: When you create a PVC with InARP configured, the PVCs was not linked to InARP chain. This means the broadcast packets are not sent through the InArp PVCs that are terminated on ATM0 interface. Because of this, routing updates are not sent causing OSPF/EIGRP neighbors to not be established.

Workaround: None.

CSCef70372

Symptom: A Catalysts MSR 8540 CES E1 structured channel connection, configured as synchronous, hangs due to line errors if the following occurs:

If bit errors (on the level BER=4E-7) occur on the ATM link between the Catalyst 8540 MSR switches the CES channel connection should stop transmitting data.

If the bit errors disappear and the CES channel link is cleared the CES channel remains in hang state and no transmissions are sent until you reset the CBR interface.

Workaround: Clear counters or enter the shutdown and no shutdown commands on the CBR interface.

CSCee67450

A Cisco device running Cisco IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DoS) attack from a malformed BGP packet. Only devices with the command `bgp log-neighbor-changes' configured are vulnerable. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet.

If a misformed packet is received and queued up on the interface, this bug may also be triggered by other means which are not considered remotely exploitable such as the use of the command `show ip bgp neighbors' or running the command `debug ip bgp <neighbor> updates' for a configured bgp neighbor.

Cisco has made free software available to address this problem.

For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20050126-bgp.shtml

CSCee43876

Symptom: Soft PVC call setup might fail going through third-party ATM switches. These third-party ATM switches might use Extended QoS Information Element (0xEC) with "Acceptable Backward Peak-to-Peak Cell Delay Variation Identifier" without the corresponding cumulative forward and/or backward Peak-to-Peak CDV.

Workaround: None.

CSCee27410

Symptom: The 8-port Gigabit Ethernet interface module (C85GE-8X-64K) does not forward broadcasts when spanning is disabled. All connected ports have problems transmitting broadcasts out if the 8-port Gigabit Ethernet interface module:

is used purely for bridging

has spanning-disabled configured on the ports in the bridge group

has non-connected ports with numbers higher than the last connected port number

Workaround: Make the connection on the 8-port Gigabit Ethernet interface module starting with the highest port number. For example, starting with port 8.

CSCee21006

Symptom: On an interface module with a soft-VC configured, if an interface is shut down or if the interface module is removed from the chassis the following cause code appears in the "debug atm sig-all" display of subsequent soft-VC requests:

cause = normal call clearing, location = User

This cause code is not correct. The "Resource Unavailable class definitions" cause code should appear.

Workaround: None.

CSCee04449

Symptom: The Catalyst 8540 MSR might experience a memory leak on the Pool Manager and Frame Relay LMI.

Workaround: None.

CSCed78149

A document that describes how the Internet Control Message Protocol (ICMP) could be used to perform a number of Denial of Service (DoS) attacks against the Transmission Control Protocol (TCP) has been made publicly available. This document has been published through the Internet Engineering Task Force (IETF) Internet Draft process, and is entitled "ICMP Attacks Against TCP" (draft-gont-tcpm-icmp-attacks-03.txt).

These attacks, which only affect sessions terminating or originating on a device itself, can be of three types:

Attacks that use ICMP "hard" error messages

Attacks that use ICMP "fragmentation needed and Don't Fragment (DF) bit set" messages, also known as Path Maximum Transmission Unit Discovery (PMTUD) attacks

Attacks that use ICMP "source quench" messages

Successful attacks may cause connection resets or reduction of throughput in existing connections, depending on the attack type.

Multiple Cisco products are affected by the attacks described in this Internet draft.

Cisco has made free software available to address these vulnerabilities. In some cases there are workarounds available to mitigate the effects of the vulnerability.

This advisory is posted at:

http://www.cisco.com/warp/public/707/cisco-sa-20050412-icmp.shtml

The disclosure of these vulnerabilities is being coordinated by the National Infrastructure Security Coordination Centre (NISCC), based in the United Kingdom. NISCC is working with multiple vendors whose products are potentially affected. Its posting can be found at:

http://www.niscc.gov.uk/niscc/docs/re-20050412-00303.pdf?lang=en

CSCed59895

Symptom: The CISCO-PROCESS-MIB is not present in Cisco IOS Release 12.0(4.6)W5(13) and Cisco IOS Release 12.0(24)W5(26c). You must configure SNMP on the switch.

Workaround: None.

CSCed59557

Symptom: On the Catalyst 8540 MSR running Cisco IOS Release 12.1(20)E, the input packet counter wraps when reaching around 65000 packets. The following example shows the interface counters:

53816 packets input, 2852248 bytes, 0 no buffer

A few seconds later, you see the following counters for the same interface display:

3067 packets input, 162551 bytes, 0 no buffer

This problem started after a reload of the switch and is seen on OC-3 interfaces.

Workaround: None.

CSCed47963

Symptom: A fiber-optic Fast Ethernet interface module connecting a Catalyst 8540 to a Catalyst 5000 interface module, WS-U5533 or WS-U5538, might flap up-and-down intermittently. This might occur once per day or for longer intervals. Both the Catalyst 8540 and Catalyst 5000 ends of the connection log the link flap.

The problem occurs with the following interface modules:

WS-U5533

WS-U5538

This problem does not happen with WS-X5236-FX-MT.

Workaround: None.

CSCed44734

Symptom: Using SNMP to create a soft VC fails if the source leg is on a VP-tunnel.

The UNDO_FAILED_ERROR appears and NOT CONNECTED appears in the X-Interface column of the show atm vc interface command display.

Workaround: None.

CSCed38527

Symptom: A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been discovered by an external researcher. The successful exploitation enables an adversary to reset any established TCP connection in a much shorter time than was previously discussed publicly. Depending on the application, the connection may get automatically re-established. In other cases, a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated connection which must be considered. This attack vector is only applicable to the sessions which are terminating on a device (such as a router, switch, or computer) and not to the sessions that are only passing through the device (for example, transit traffic that is being routed by a router). In addition, this attack vector does not directly compromise data integrity or confidentiality.

All Cisco products which contain TCP stack are susceptible to this vulnerability.

This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-ios.shtml, and it describes this vulnerability as it applies to Cisco products that run Cisco IOS® software.

A companion advisory that describes this vulnerability for products that do not run Cisco IOS software is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-nonios.shtml.

Workaround: None.

CSCed27956

Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated connection which must be considered. This attack vector is only applicable to the sessions which are terminating on a device (such as a router, switch, or computer) and not to the sessions that are only passing through the device (for example, transit traffic that is being routed by a router). In addition, this attack vector does not directly compromise data integrity or confidentiality.

All Cisco products which contain TCP stack are susceptible to this vulnerability.

This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-ios.shtml, and it describes this vulnerability as it applies to Cisco products that run Cisco IOS® software.

A companion advisory that describes this vulnerability for products that do not run Cisco IOS software is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-nonios.shtml.

Workaround: None.

CSCed20914

Symptom: Using the show switch fabric command to request information about the different interfaces connected to the chassis does not reflect all of the different interface connections. Only the 155-Mbps interfaces appear in the display.

Workaround: None.

CSCec80061

Symptom: A switched virtual circuit (SVC) may not get established causing ping command failures between routers. This symptom is observed in Cisco IOS Release 12.3.

Workaround: None.

CSCec37094

Symptom: Building integrated timing supply (BITS) clocking problems.

If the clock source is changed to BITS and the network clock module fails to lock on to the BITS source, the network clock on the Catalyst 8540 MSR switches back to "System" (the internal Stratum 3 NetClk module). Immediately after that change, the primary route processor of the Catalyst 8540 MSR reloads because of a memory alignment error.

Workaround: None.

CSCeb52110

Symptom: On a Catalyst 8540 MSR running Cisco IOS Release 12.1(7a)EY, if you OIR the CES interface module the route processor might crash.

Workaround: None.

CSCeb29970

Symptom: When establishing soft-VP between switches, if a VP number is used by the previous switch and if that switch sends an error stating that "VPI" is already used, then the switch receiving that error should use a different VPI number during its next retry attempt. For example

Switch-1 (1/0/0)-------(1/0/0) Switch-2 (1/1/1)---------(1/1/1) Switch-3 (1/1/0)

1. Assume a soft-VP call is getting initiated by Switch-1.

2. Assume that the node ID of Switch-3 is higher than Switch-2.

3. Assume that the Switch-2 ATM1/1/1 interface has a PVP configured with VPI 4 (ATM PVP 4).

In this scenario, when a call is initiated by Switch-1, it is forwarded by Switch-2 to Switch-3. Because the node ID of Switch-3 is higher than Switch-2, Switch-3 requests a VP number. If the request is for VPI 4 on Switch-3's ATM1/1/1, it will reach Switch-2's ATM1/1/1. Because there was a PVP configured on Switch-2's ATM1/1/1 interface with PVP 4, it is rejected stating that VPI is "unavailable". This error is sent to both Switch-1 and Switch-3. So, during the next attempt when Switch-3 requests a VPI number, it should request a different VPI number from 4.

Workaround: None.

CSCeb13499

Symptom: Problems occur in CISCO-ATM-IF-PHYS-MIB implementation:

1. ciscoAtmIfPhysLineFebeErrors returns Path FEBE errors instead of Line FEBE

errors.

2. ciscoAtmIfPhysPathFebeErrors returns Line FEBE errors instead of Path FEBE

errors.

This only happens with OC-3/STM1 or OC-12/STM4 interfaces.

Workaround: Poll ciscoAtmIfPhysLineFebeErrors when you need Path FEBE errors and poll ciscoAtmIfPhysPathFebeErrors when you need Line FEBE errors.

CSCea74771

Symptom: The ATM interface does not reset the VCI/VPI connection after restart.

Workaround: None.

CSCea72899

Symptom: Soft PVC does not come up.

If a Soft PVC originates from a Catalyst 8500 switch directly connected to an Alcatel switch, the Soft PVC never comes up. If the call originated from the Alcatel side, the Soft PVC comes up with no problem.


Note This occurs if the Catalyst 8500 switch is running Cisco IOS Release 12.0(24)W5(26b).


For example:

At UNI ATM interface:

atm soft-vc 1 455 dest-add xx.348f.8001.bbfc.0000.0ba0.6f10.4080.210a.2a01.00 1 455 rx-cttr 1 tx-cttr 1

Alcatel switch directly connected, ATM NNI, PNNI up and adjacency up:

CSCea66219

Symptom: A memory leak occurs in the ATMSIG processes. This is observed using the show processes memory command. The ATMSIG processes hold increasing amounts of memory and free memory is decreasing.


Note This occurs on LightStream 1010 or Catalyst 8540 switches running Cisco IOS Release 12.0(24)W5(26b), Cisco IOS Release12.1(12c)E, or Cisco IOS Release 12.1(13)E1.


Workaround: None. The switch must be rebooted to recover.

CSCea56751

Symptom: When configuring a soft-VC on the Catalyst 8540 or the switch on the other end, the VC will not come up.

The debug atm sig-soft command shows the following on the Catalyst 8540 MSR.

CSCea33595

Symptom: On a switch running Cisco IOS Release version 120-24.W5.26b, the switch might crash due to a system restarted by a bus error at PC 0x6063F9C8, address 0xD0D0D15.

Workaround: None.

CSCea30004

Symptom: Whenever you attempt to update the Access Control List (ACL) attached to the management interface (Ethernet2/0/0) on the switch, the following error message appears:

ACL is not supported

ACL functionality on the interface is not affected.

Workaround: None.

CSCea26176

Symptom: The Catalyst 8540 CSR might display the following messages when running Cisco IOS Release 12.0(20)W5(26) software:

Jan 9 160611 EST %ALIGN-3-CORRECT Alignment correction made at
0x603954BC reading 0x6200E625

6036BB58 60076ABC 6005C948 6005CA80 6005CDCC 6007C4E4

There is no noticeable impact to the operation of the switch.

Workaround: Downgrade to Cisco IOS Release 12.0(20)W5(24a) software or earlier.

CSCea16981

Symptom: On the Catalyst 8540 CSR the Underruns counter on the egress interface increment. This occurs because the Catalyst 8540 CSR is a cut through switch and it starts forwarding once a predefined number of bytes are received by the ingress interface. However, if any input errors occur (for example, bad CRC, alignment errors, or giant packet errors) after the switch starts forwarding, the switch would have already started forwarding the frame and will register an underrun error on the egress port.

To determine the cause of underruns on a particular interface, the counters on all other Fast Ethernet or Gigabit Ethernet interfaces need to be checked for input errors and eliminated.


Note The input error counter on the EPIF based 2-Port Gigabit Ethernet module does not increment and bad frames are dropped by the GMUX on the module.


Workaround: None.

CSCea07394

Symptom: Under certain circumstances, when an OC-12 interface flaps up-and-down on a Catalyst 8540 MSR running Cisco IOS Release 12.1(12)E or EY software, the switch fabric might start dropping cells on VCs exiting this interface

Workaround: This problem might go away if you reload the switch image.

CSCea02355

Symptom: Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available.

Cisco has made software available, free of charge, to correct the problem.

Workaround: This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml

CSCdz71298

Symptom: The Catalyst 8540 might display following error messages:

Workaround: None.

CSCdz52991

Symptom: Internal buffers (vbufs) are exhausted, ASSERTION FAILED, and some high-priority IPC (interprocess communications) drops occur.

Workaround: None.

CSCdz34607

Symptom: Ethernet interface modules fail Online Access Test after upgrade from Cisco IOS Release 12.0.5.W5.13 to Cisco IOS Release 12.0.22.W5.25.

Workaround: This access test failure is caused by the incompatibility of hardware version (4.1) and firmware version (2.1) of the Ethernet interface modules installed in the switch. By upgrading to the latest firmware version (3.3), this problem can be resolved.

CSCdz32265

Symptom: The show ces address command has been enhanced to provide CES address directly via SNMP for the Catalyst 8540 MSR.

Workaround: None.

CSCdz08249

Symptom: On a Catalyst 8540 MSR switch, in the show switch fabric command display the Rx Cells and Tx Cells counters remain at 0 under MSC3 even though traffic is flowing through the ports linked to that MSC.


Note This issue is cosmetic and normal traffic flow is not impacted. It is only a counter issue.


Workaround: None

CSCdy81832

Symptom: Cell drops occur at an OC-12 interface module with a Hierarchical VP tunnel if the hierarchical VP tunnel is configured on interface 0, the primary Route Processor is in slot 8, and the secondary Route Processor has come up in slot 4.

This same problem might occur if a hierarchical VP tunnel is defined on interface 9, the primary Route Processor is in slot 4, and the secondary Route Processor has come up in slot 8.

This happens when the secondary Route Processor boots up and there is a Hierarchical VP tunnel on any of the interfaces that share the same MSC as the secondary Route Processor.

This does not occur if the Redundant Route Processor is never booted.

Workaround: Use slot 2 or slot 11 for OC12 interface module with the hierarchical VP tunnel.

CSCdy80652

Symptom: Input errors on interface ATM0 are incrementing one per minute. Only Input errors is incrementing and no other counters (For example, CRC and other errors).

Workaround: None.

CSCdy77179 (This defect is archived.)

Symptom:

The Cisco Catalyst 8540 switch running Cisco IOS Release 12.0(18)W5(22) might experience a memory leak in pool manager.

The system logs may indicate tracebacks similar to the following:

%SYS-2-MALLOCFAIL: Memory allocation of 496 bytes failed from 0x6006CA58, pool
Processor, alignment 0 -Process= "Pool Manager", ipl= 6, pid= 4
-Traceback= 6009E434 6009FEE0 6006CA60 600AA200 6009968C 60099678

For further information on memory leaks, refer to Troubleshooting Memory Problems http://www.cisco.com/warp/public/63/mallocfail.shtml#subfour

Workaround: None.

CSCdy59574

Symptom: The K1 might reset itself when a getbuffer fails in Cisco IOS software for tunneled packets or IPC through mailbox.

Workaround: None.

CSCdy58420 (This defect is archive)

Symptom: A Catalyst 8540 MSR switch running Cisco IOS Release 12.0(16)W5(21a) may display the following error message:

%ATMCORE-3-INTERNAL_ERROR: ATOM ERROR: leg->snmpInfo.xconnectIndex is NULL

This message is displayed during SNMP polling.


Note There is no impact on switch performance.


Workaround: None.

CSCdy57099

Symptom: The Catalyst 8500 MSR switch might experience a memory leak with the IP Simple Network Management Protocol (SNMP) process.

Workaround: None.

CSCdy45231

Symptom: The IMA interface module does not generate a syslog message when the link goes down.

Workaround: None.

CSCdy10719

Symptom: Hosts that do not transmit data frequently and are connected to the Catalyst 8500 switch through an 8-port Gigabit Ethernet module are intermittently unreachable.

The connectivity to the hosts eventually recovers.

Workaround: None.

CSCdy10600

Symptom: Enable optipoll by default on switches running 12.0W5 based images to permanently remove ILMI/SNMP timing issues for ILMI keepalive messages.

Workaround: None.

CSCdy07314

Symptom: A Catalyst 8500 MSR running Cisco IOS Release 12.0(20)W5(24b) might crash with a bus error in the SNMP code.

Workaround: Disabling polling chassis MIBs might prevent the crash.

CSCdx94423

Symptom: If you disconnect the transmit cable from an E1 CBR interface on a Catalyst 8540, the interface still appears up/up. No indication of error messages appear in the log files.

When the transmit cable is reconnected, it starts to transmit traffic again. However, if the transmit cable is disconnected multiple times, the link does not pass traffic even when the transmit cable is reconnected.

Workaround: Use the shutdown and no shutdown commands on the interface and it returns to normal, or disconnect the receive cable and reconnect it.

CSCdx93120

Symptom: On a Cisco 6400 Node Switch Processor (NSP) running Cisco IOS Release 12.2(2)B and its derivatives, using the atm ping command to test a valid and active VP might fail with the following message:

Jun 20 15:56:17.742: %ATMCORE-3-INTERNAL_ERROR: atmCore_oamRcvPing: No match.

The failure occurs when running the ping towards specific destination ATM switches, and is dependent on the format of the loopback cell received from the destination ATM switches. The occurrence of this problem is difficult to predict and depends on the particular ATM switch implementation of the destination switch.

Workaround: None.

CSCdx91019

Symptom: A Cisco 6400 NSP, running Cisco IOS Release 12.1(5)DB or 12.2(2)B, displays the following error message when you use the atm ping interface atm slot/subslot/port VPI VCI end-loopback command and enter the wrong VP/VC combination:

connection doesn't exist

Any future atm ping commands to any connections (both valid and invalid) always result in the same error message and the ping commands fails. It fails even if the connection is valid, and even if a VP ping is used (for example, no VC number is specified).

You can still use the IP ping command to diagnose the connectivity between the NRP2 (Node Route Processor 2) and NSP.

Workaround: None.

CSCdx86521 (This defect is archived.)

Symptom: Queue stuck on Catalyst 8540 MSR switch backplane. One of the cross-connect VCs on the ATM switch backplane is stuck and causing packet loss on traffic passing over the stuck VC.

Workaround: Either OIR the interface module (either a software OIR or the physical OIR) or reload the software image.

CSCdx75935

Symptom: A Catalyst 8540 CSR configured for IRB/BVI does not perform MAC learning in the microcode based on the reception of ARP requests. This includes gratuitous ARPs. This might cause problems with redundancy and failover mechanisms that rely on advertising the new location of a virtual IP/MAC pair via gratuitous ARP. Gratuitous ARP updates the bridge and ARP tables of devices in the network when a failover occurs. The Cisco PIX firewall also uses this mechanism for failover.

Workaround: There is no workaround for this problem in an IRB configuration on this platform. In a bridging only configuration, this problem does not occur.

Clearing the bridge table removes the condition. After the aging period (5 minutes) the connection is also restored.

CSCdx73702

Symptom: Switch processors must be the same hardware version or boot failure occurs. For example, a switch processor with hardware version 8.0 and RMA=0 and a switch processor with hardware version 7.2 and RMA=1, cause the switch to hang when booted. But, RMA number does not matter, for example, a switch processor, hardware version 8.0 with RMA=0 and a switch processor, hardware version 8.0 with RMA=1 function correctly in the same chassis.

This creates an issue when RMAing a new unit. You MUST check the switch processor hardware version in lab first to determine if it is the same version as the switch processor installed in the chassis.

Workaround: Remove ALL linecards and leave only the two switch processors and one route processor in the chassis. this will boot successfully and then you can determine the hardware versions (Hw Vrs) of each switch processor and confirm that they are the same.

CSCdx70586

Symptom: Loopback not working properly on ATM T1 interface module. Duplicate of DDTS CSCdw22559.

Workaround: None.

CSCdx61473

Symptom: A switch running Cisco IOS Release 12.0(19)W5(23) might display the following error messages in the log:

%SYS-2-NOBLOCK: idle with blocking disabled.

CSCdx58649

Symptom: Avaya PBX and Definity PBX interoperability testing.

The following caveats exist for signalled ATM point-to-multipoint (P2MP) connections and the debugging of issues related to them on the Catalyst 8500 ATM switches:

Hardware processing to release connection IDs (VPI/VCI) on low-rate P2MP connections can be slow. When add party /drop party are issued in quick succession on such a connection, insufficient time is spent waiting for completion, which causes an unnecessary rejection of the add party. There is no workaround for this issue.

When a slave NNI node (in terms of connection ID allocation) proposes a connection to the master, and the master then uses the proposed VPI/VCI itself (intending to give the slave-proposed-VC another connection ID), two SVCs end up owning the same underlying VC. The result is a dangling half-leg and possibly allocated bandwidth that is never returned. There is no workaround for this issue.

Handling of unexpected values in the second byte of the ATM signalling message-type field is to drop the message. This is incorrect. There is no workaround.

Several debug messages received during "error" debugging are normal events. This causes clogging of the log buffer with nonerrored messages. This is for "mmc errors" and "atm sig cc-errors".

Workaround: None.

CSCdx56878

Symptom: A Catalyst 8540 MSR running Cisco IOS (tm) PNNI Software (cat8540m-WP-M), Release 12.0(20)W5(24a) RELEASE SOFTWARE, and using the QUAD E3 interface module might experience a limitation to the number of soft-VCs that can be established to its interfaces.

Output seen on the remote switch indicates "NOT CONNECTED" when using the show atm vc command.

The following similar output might appear when using the debug atm sig-soft interfaces atm card/subcard/port command:

*May 14 06:57:09.511: ATMSOFT(ATM10/1/0 vpi = 249; vci = 32 ) Received SETUP

Workaround: None.

CSCdx55288

Symptom: When setting up SVCs over an NNI link, one system becomes the master in terms of deciding which VPI/VCIs are assigned to SVCs. When the slave signals a Connection ID in SETUP, it may specify a VPI/VCI value. The Catalyst 8540 MSR signals the lowest VCI in the address range.

When signaled over a VP tunnel, the Connection Identifier IE formulated by the slave specifies that the VCI signalled is to be ignored.

However, when connection management allocates the half-leg for the ingress interface, if the connection ID specified in the ID matches an already-existing connection, and the connection signaled is point-to-multipoint link, the Connection Manager assumes the signaled SVC is the same as the one already allocated. This causes two SVCs point to the same VPI/VCI. This, subsequently, results in the deletion of the existing half-leg, the bandwidth allocated by the SVC lost, and the existing connection turned into a half-leg connection (dangling).

Workaround: None. The dangling half-leg can be recovered for SVCs by using the shutdown and no shutdown commands on the interface.

CSCdx55287 (This defect is archived)

Symptom: You should not configure a structured CES circuit with more than 19 timeslots across a T1 ATM interface on a Catalyst 8540 MSR. While the circuit can be configured with more than 19 timeslots and will be built over the T1 ATM interface, the Catalyst 8540 MSR will discard cells on the configured VC causing errors on the emulated circuit.

With 20 timeslots configured you see cells queued and dropped (CLP0 Q full drop) on the PVC. This problem occurs when both hard and soft PVCs are configured over the T1 ATM interface.

To detect the problem, use the show atm vc int atm card/subcard/port vpi vci command and confirm the Clp0 q full drops field is increasing.

CSCdx47684

Symptom: A PNNI PVC link on an NNI interface might flap after the link stabilizes and the ATM PNNI VC component does not come back up.

Workaround: "Bounce" the PNNI process using the no atm router pnni and atm router pnni configuration commands to disable and enable the PNNI processes.

CSCdx40547

Symptom: Many PHY parity errors might appear on your switch from traffic through the OC-12 line module which causes PHY Parity Error interrupts. This could cause high CPU utilization (approximately 90percent) during a route processor switchover. This problem is caused by the PHY Parity Check bit in the SMR register being set to "1"(enabled) on a route processor switchover. The SMR register is set from 0x0 to 0xF during switchover, thereby enabling the PHY Parity Check bit. This default value of this register should be 0x0 (PHY Parity Check disabled).

Workaround: None.

CSCdx40271

Symptom: An unexpected reload of the switch occurs when you try to set the MIB object pnniSummaryAddressSuppress (PNNI-MIB).

This occurs when there is a summary for an ATM address prefix and you are still trying to set a summary suppress for the same ATM address prefix through the SNMP interface.

Workaround: None.

CSCdx24636

Symptom: The Catalyst 8540 MSR running Cisco IOS Release 12.0(18)W5(22) is unable to ping device off of the 8 port Gigabit Ethernet interface module.

Reload resolves this issue temporarily, only to reoccur in 10 to 15 days.

Workaround: Reload the switch.

CSCdx20833

Symptom: A Soft VC or Soft PVC connecting two ATM interfaces in the same Catalyst 8540 MSR might become stuck for no reason.

Workaround: Remove and reapply the Soft VC configuration on the source ATM interface.

CSCdx12317

Symptom: After you perform an OIR or a switch reload, the counter from show atm interfaces atm command displays an incorrect output rate value.

Workaround: None.

CSCdx06532

Symptom: A SNMP get-request on the MIB object pnniLinkIfIndex that is defined in the PNNI-MIB module returns 0.

This symptom is observed on PNNI interfaces of Cisco ATM switches. The symptom does not occur on virtual path tunnel interfaces.

Workaround: None.

CSCdx04773

Symptom: When the Cisco ATM switch is running UNI 4.0 with a Fore or Marconi switch, it might release a call because of unsupported traffic parameters.

This occurs when the Cisco ATM switch is connected to the other vendor equipment and configured to operate with UNI 4.0 version across the link and as a non-negotiated link. If any traffic parameter values are modified, the Cisco ATM switch treats this as a fatal error and releases the call.

Workaround: Hardcode the UNI version to 3.1

CSCdw95262

Symptom: On Frame Relay soft VCs, all frames sent with DE (discard eligibility) bit set are dropped at the serial interface even when the UPC is configured as "tag-drop" for the Soft VC.

Workaround: None.

CSCdw93109

Symptom: When using ATM Frame Relay IWF on a Catalyst 8500 MSR running Release 12.0(18)W5(22) or later, the output queue of the pseudo-ATM interface might go to 40/40 and remain there even if no traffic is going through the switch on the ATM-FR circuits.


Note A reload might be required to clean that counter but connectivity is not impacted.


Workaround: None.

CSCdw86290 (This defect is archived)

Symptom: On an ATM router module (ARM) that is running Cisco IOS Release 12.0(13)W5(19c), the ARM port may become stuck when a backup server is moved to a different switch.

Workaround: Configure the epc port-reload global configuration command for autorecovery on the stuck ARM port.

CSCdw84976

Symptom: When a port on a Catalyst 8540 CSR is configured as a snoop (monitor) port, the traffic on the snoop port becomes corrupted. Sniffing the same traffic on the attached Catalyst switch shows that the traffic itself is not corrupted. The problem occurs because the snoop port does not give reliable information to the monitoring station attached to that port.

Workaround: None.

CSCdw84540

Symptom: LightStream 1010 switches running 12.0(X)W5 IOS may not completely adhere to the ITU-T Q.2971 "B-ISDN DSS2 UNI Layer 3 Specification for Point-to-Multipoint Call/Connection Control." This could affect interoperability.

Workaround: Configure UNI Version 3.1 on the switch interfaces if the point-to-multipoint interoperability issue is observed.

CSCdw70257

Symptom: A switch configured for IMA bundling may not log link up and down messages. Only messages displaying the clock changes are logged as in the following example:

04:23:21: %CLOCKSW: Switching from ATM1/1/1 to ATM1/1/0
04:24:26: %CLOCKSW: Unswitching from ATM1/1/0 to System
04:25:21: %CLOCKSW: Switching from System to ATM1/1/1
04:26:06: %CLOCKSW: Unswitching from ATM1/1/1 to System

As each interface recovers revertive clocking the messages appear correctly and source is recovered. Messages appear incorrectly if there are multiple links going up and down and only CLOCKSW messages are received without reporting status of the interface.

The correct physical status can be viewed properly with the show ima interface and show ima interface atm card/subcard/port detail commands. These commands accurately display the status of the port with usual counters.


Note This behavior is not seen when the switch is configured as stand alone.


Workaround: None.

CSCdw65903

Symptom: An error can occur with management protocol processing.

Workaround: Use the following URL for further information: http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903

CSCdw41639

Symptom: The switch silently drops OAM F5 with OAM intercept enabled.

The switch might drop OAM (Operation Administration and Maintenance) F5 END Loopback cells with its default configuration of OAM intercept.

Workaround: Disable OAM intercept to avoid dropping F5 OAM cells.

CSCdw40185

Symptom: Multicast packets of some specific lengths (121 bytes to 240 bytes) cause a portstuck condition on the ATM router module interfaces.

Workaround: None.

CSCdw36542

Symptom: The IRB connection has no connectivity in a native VLAN across ISL/dot1q Gigabit Etherchannel in the same bridge-group. However, there is connectivity on other VLANs.

Workaround: Configure a dummy VLAN as a native VLAN on the dot1q trunk.

CSCdw33859

Symptom: If you use the no negotiation auto command in interface configuration mode on a 2-port Enhanced Gigabit Ethernet interface module with GMAC-D2 (hw-version 6.0 onwards), any packets larger than 1518 bytes or less than 64 bytes are filtered by the GMAC (Gigabit Ethernet Media Access Controller).

Workaround: Reload the particular interface using the epc portstuck-manual-reload interface card/subcard/port command.

CSCdw33652

Symptom: If you configure VC-snooping on a sub-interface, then delete the subinterface, then recreate it, and if you then use the no atm snoop command to disable snooping on the same subinterface, the switch crashes.

Workaround: None.

CSCdw33641

Symptom: The console might hang if you use the hw-module subslot x/y reset command on the Frame Relay E1 port adapter.

Workaround: Shutdown all the controllers in the port adapter before issuing the hw-module subslot x/y reset command.

CSCdw31172

Symptom: Unusual delays occur in Frame Relay VC counter updates on Frame Relay ATM interface modules.

Workaround: None.

CSCdw27572 (This defect is archived)

Symptom: A LightStream 1010 running 12.0(19)W5(23) showed the following alignment error:

Dec 11 08:04:28.227 MET: %ALIGN-3-CORRECT: Alignment correction made at 0x60329860 reading 0x614202C1

Workaround: None.

CSCdw25030

Symptom: After upgrading to Cisco IOS Release 12.0(19)W5(23) the following error message appears in the system log:

*Nov 25 15:47:31: ACL Daughter Card detected on the PAMin Slot [9]
*Nov 25 15:47:32: ipc_send2wire: No Mlet code for type: 111
*Nov 25 15:47:32: ipc_send2wire: No Mlet code for type: 111

This has no effect on the switch.

Workaround: None.

CSCdw22559

Symptom: When an IMA interface module is installed in the switch chassis, and if "loopback PIF" is configured on any OC-3 or OC-12 interface, loopback is NOT reflected when queried through SNMP. Loopback is NOT actually being set.

Workaround: None.

CSCdw20972

Symptom: If an IMA port that is connected to an IMA interface module installed in a Catalyst 8540 MSR is reset, it can cause the installed IMA interface module to fail.

Workaround: An OIR of the IMA interface module clears the failed state and restores service.

CSCdw11289

Symptom: Only 147 Mbps of resources are available on the ATM interfaces of the ARM and ARM II modules.

Workaround: None.

CSCdw10699

Symptom: The output of the show memory command displays incorrect values for PrevF and NextF fields. This may result in the Exec stack getting corrupted. This has no impact on the performance of the switch.

Workaround: None.

CSCdw15274

Symptom: A high number of cells stuck in the memory buffer causes the CPU to miss the periodic poll of a certain module or interface, leading to a port stuck message. Occurrences are random and there is no predetermined sequence of events that causes this to happen.

Workaround: None.

CSCdw10624

Symptom: You might see a Bus Error exception at get_slot_ptr while trying to do the continuous snmpwalk on the ciscoLS1010SubModuleGroup object of CISCO-RHINO-MIB and simultaneously toggling the redundant power-supply after at least one route processor switchover.

Workaround: None.

CSCdw09740

Symptom: For Frame Relay terminating PVCs on Catalyst 8540 MSR, Catalyst 8510 MSR, and LightStream 1010 switches, effective "Inverse ARP Frequency" value will be 60,000 times greater than the actual intended value.

Workaround: None.

CSCdv82794

Symptom: The Catalyst 8540 might experience a port stuck condition on the ATM router module (ARM) interface with a PVC configured.

Workaround: Use the epc port-reload command to automatically recover from portstuck.

CSCdv71210

Symptom: Shaping is not available for outgoing signalling VC on the Catalyst 8540 MSR switch.

Workaround: None.

CSCdv70086

CSCdv67501

Symptom: Once the route processor switches over, the following error message is seen on the new Primary route processor if you have a Gigabit processor interface module installed:

%ONLINEDIAG-6-ACCESS_TEST_WARNING: Unable to read from card in slot 10 sub_card 0.

Enter the show diag online access command to get more details about the failure.

Workaround: None.

CSCdv66300

Symptom: The "DE bit tagged locally" counter should increment for all frames above the CIR and conforming to the policy. This feature is available on Stratacom ATM switches.

Workaround: None.

CSCdv63139

Symptom: A Catalyst 8500 switch rejects SVC video calls. After first video call is built, all other video calls are rejected, and a message similar to the following is generated when a debug atm sig-all atm x/y/z command is entered:

ATMSIG(0/0/0:11 11,35 - 0023/00):

Workaround: Upgrade the Catalyst 8500 switches to Cisco IOS Release 12.1(7a)EY.

CSCdv60858

Symptom: A crash occurs while configuring Bridge Group Virtual Interface (BVI)/Enhanced Interior Gateway Routing Protocol (EIGRP), or while powering off the redundant power supply.

Workaround: None.

CSCdv49358

Symptom: When a CES circuit carrying traffic is removed, there is no warning message shown.

Workaround: None.

CSCdv48352

Symptom: When running Cisco IOS Release 12.0(18)W5(22) on a Catalyst 8540 MSR, or on a LightStream 1010, interoperability problems occur when peers run an older IOS version, and tunnels and SVC/Soft VCs are used.

Workaround: Upgrade all switches to the most current IOS release.

CSCdv44896

Symptom: When using snmpwalk and the getbulk operation on the MIB tree, a memory leak occurs.

Workaround: None.

CSCdv43426

Symptom: When a Catalyst 8540 MSR system has a large number of inverse multiplexing over ATM (IMA) port adapter modules, a message similar to the following is generated:

-Process= "IMAPAM Onesec", ipl= 6, pid= 70
-Traceback= 600D8280 600D8644 6049F928 600C03CC 600C03B8
%SCHED-3-THRASHING: Process thrashing on watched message event.

Workaround: None.

CSCdv41809

Symptom: On the CES module interface, the status reads UP/UP and the status of PVC to that interface is UP in even though there is no physical connection at that port.

Workaround: Perform shutdown and no shutdown on the interface to clear the erroneous status.

CSCdv36089

Symptom: A forced crash occurs.

Workaround: None.

CSCdv35065

Symptom: PNNI goes to "down" state on all interfaces and all adjacencies are lost.

Workaround: None.

CSCdv25341

Symptom: A Catalyst 8540 MSR and Catalyst 8510 MSR connected via 8-port inverse multiplexing over ATM (IMA) port adapter modules change clocking configuration after the T1 interfaces bounce, resulting in a loss of synchronous clocking over the T1 IMA links. If synchronous clocking is required for circuit emulation service (CES), the CES circuit might report overruns or underruns.

Workaround: The Catalyst 8540 MSR and Catalyst 8510 MSR can be reloaded to return the clocking configuration to the original values. The T1 interfaces can be removed from the IMA group, and then can be added back and bounced. The txtiming values under the show controllers will change back to 0x2 and synchronous clocking is restored.

Workaround: None.

CSCdv22476 (This defect is archived)

Symptom: On Frame Relay to ATM Soft PVC connections the Frame Relay UNI interface status is incorrect. The soft-VC PVC status is marked Active only when the soft-VC is established and its connection state is UP. If the soft VC is not connected, the source end of the soft-VC indicates the PVC status as INACTIVE instead of ACTIVE, while the destination end of the soft-VC does not exist and hence indicates the PVC status is DELETED.

Workaround: None.

CSCdv21398

Symptom: The Management Information Base (MIB) object "ifAdminStatus" shows "UP" for an ADMIN DOWN E1 Controller after a reload or a route processor switchover.

Workaround: Enter the no shutdown/shutdown command sequence on the controller.

CSCdv17275

Symptom: SK Kernel on the 8-port Gigabit Ethernet module occasionally crashes.

Workaround: Run any IOS Release prior to Release 12.1(5)EY.

CSCdv15294

Symptom: On the Frame Relay interface module, if any DROPS occur, the INPUT/OUTPUT ERROR counter is incremented instead of INPUT/OUTPUT DROPS counter.

Workaround: None.

CSCdv15245

Symptom: When Frame Relay ATM soft-VC is set up in Frame Relay/ATM Network Interworking (FRF.5), the usage parameter control (UPC) on the passive side always sets to PASS, irrespective of the setting on the serial interface that is set by entering the frame-relay upc-intent tag-drop command. The default is PASS; when this is changed to tag-drop, the configuration does not reflect the change, and entering the show vc int serial command always shows the UPC intent as PASS.

Workaround: None.

CSCdv09975

Symptom: When the shutdown/no shutdown command sequence is entered for a port in a CES card, a burst of bit errors can be observed on the circuit on some other port of the same port adapter.

Workaround: None.

CSCdv06370

Symptom: Not all of the contents of the atmVcCrossConnectTable can be seen after the removal and re-insertion of a module. The message:

%ATMCORE-3-INTERNAL_ERROR: ATOM ERROR: ifCB_p=NULL for lowIf

is seen on the console during some SNMP get operations.

Workaround: None.

CSCdv05916 (This defect is archived)

Symptom: When an E1 IMA (inverse multiplexing over ATM) adapter is inserted into a chassis in which several other IMA adapters have already been added, the clock cannot be derived from the network.

Workaround: None.

CSCdu83797

Symptom: Some point-to-multipoint crossconnnect entries are missing from the atmVcCrossConnectTable when the point-to-multipoint root if-index is higher than the if-index of the leaves.

Workaround: None.

CSCdu83707

Symptom: Interfaces with Tag enabled get stuck in the TDP not ready state.

Workaround: None. The only way to bring up the Tag on such interfaces is via system reload.

CSCdu83704

Symptom: During TagVC installation, if the switch driver returns an error, the Connection Manager leaves the TagVC in the wrong FSM state. This can lead to TVCs existing on an interface when there are no tag bindings.

Workaround: None; reload the switch to clear such unused TVCs.

CSCdu82922

Symptom: When running Cisco IOS Release 12.0(13)W05(19), a bus error causes the system to restart. This occurs when an 8-port Gigabit Ethernet card with control traffic is at or near its traffic capacity.

Workaround: None.

CSCdu78056

Symptom: The SNMP TRAP object ccrCpuStatusChange returns an invalid value.

Workaround: None.

CSCdu77737

Symptom: A Catalyst 8510 reloads by bus error.

Workaround: None.

CSCdu77058

Symptom: When a Catalyst 8540 with a network clock module is connected to an external clock supply, changing the clock supply from BITS 0 to system causes the system to crash.

Workaround: None.

CSCdu74491

Symptom: After reloading core switches, all neighboring switches running 12.0(16)W6(21) and 12.0(16)W6(21a) crash and a message similar to the following is generated:

CSCdu69809

Symptom: A port of a 4-port DS3 port adaptor for LS1010s and 8540s is in a yellow or red alarm state, and stops sending DS3 framing for a brief time when the alarm is cleared from the interface and the interface transitions to an up/up state. The loss of frame (LOF) can be seen when the Acterna tool TBERD is connected to the TX port of the DS3 port.

Workaround: None.

CSCdu57105

Symptom: When using Cisco IOS Release 12.0(16)W5.21, a system crash with a bus error at imapam_mmcport_init occurs after the creation of the 131st interface.

Workaround: Remove any unused modules from the chassis so that additional virtual interfaces can be created.

CSCdu56774

Symptom: 4-path load balancing is missing for Ethernet processor interfaces.

Workaround: None.

CSCdu56203

Symptom: On a Catalyst 8540 MSR, use of the OIR online diagnostic disables the E1 interface after reloading.

Workaround: None.

CSCdu55104

Symptom: After an online insertion and removal (OIR) of a carrier module in the 8540 MSR, the input/output packet counters for the corresponding interfaces show incorrect values.

Workaround: Do not perform OIRs, or clear the counters on that interface.

CSCdu39907

Symptom: The command line interface (CLI) no negotiation auto command is not preserved in the running configuration after an OIR (or "hot swap") of an 8-port Gigabit Ethernet card.

Workaround: Configure the CLI no negotiation auto command again.

CSCdu37838

Symptom: The spanning tree protocol of a bridge-group cannot be changed.

Workaround: Deconfigure the bridge-group and then reconfigure it with a different spanning tree protocol.

CSCdu35316

Symptom: When a user specifies a Soft PVP Configured as VBR-NRT Service category in the ingress port, the service category at the egress interface of that switch is seen as UBR rather that VBR_NRT.

Workaround: None.

CSCdu30996

Symptom: After a switch processor or route processor switch over, incorrect values appear in the show interface atm display counters for the OC-3 interface module.

Workaround: Reload the switch.

CSCdu26719

Symptom: A Catalyst 85xx running Cisco IOS Release 12.0(13)W5(19c) experiences high multiservice route processor utilization when Internetwork Packet Exchange (IPX) networks are added to Bridge Group Virtual Interface (BVI) interfaces; as more IPX networks are added, multiservice route processor utilization increases.

Workaround: If configuring bridging over ATM router module subinterfaces, configure a map-list for the bridged virtual circuit, using the keyword "bridge".

For example:

     interface ATM3/0/0.50 multipoint
        no ip directed-broadcast
        map-group b50
        atm pvc 2 50 pd on interface ATM0/0/0 1 50
        bridge-group 50
     map-list b50
        bridge atm-vc 50 broadcast

CSCdu25511

Symptom: FR-PVCs configurations might fail after a route processor switchover.

Workaround: Reload the switch router.

CSCdu24272

Symptom: On ATM switches, the loopback IP address is not exchanged during ILMI negotiation with the neighboring switches. Consequently, the output of the show atm ilmi-status command indicates 0.0.0.0 as the peer IP address, even though a loopback address is configured.

Workaround: Configure the IP address on an Ethernet interface.

CSCdu21174

Symptom: A Catalyst 8540 CSR with an 8-port Gigabit Ethernet module forwards duplicate broadcasts when bridging is configured on a trunk.

Workaround: None.

CSCdu20618

Symptom: One side of a circuit emulation service (CES) E1 port of a the switch connection remains consistently in the YELLOW alarm or ALARM INTEGRATION state.

Workaround: None.

CSCdu16973

Symptom: When running cell-mode MPLS on a network of switch routers with redundant paths, conversion to MPLS after a routing change might take up to 4.5 minutes. OSPS converges normally.

Workaround: None.

CSCdu10985

Symptom: An ARM interface might not bridge between ATM and the native VLAN.

Workaround: Configure some other non-functional VLAN as native.

CSCdu09850

Symptom: On a Catalyst 8540 performing an ATM-Frame Relay internetworking function, the ATM-Frame Relay does not propagate when the Local Management Interface (LMI) indicates a permanent virtual connection (PVC) as inactive.

Workaround: None.

CSCdu07640

Symptom: The no ip route-cache cef command might disappear from the running configuration of the BVI interface after reloading the switch router.

Workaround: None.

CSCdu04045

Symptom: The entry for atmSoftPVccRetryThreshold feature has an incorrect default value of 0, rather than the default value of 1 that is shown in the ATM Soft PVC Management Information Base (MIB).  A value of zero indicates that an infinite number of call attempts are required to increment the atmSoftPvcCallFailures object and thus disables alarms for the Soft PVCC.

Workaround: Set the atmSoftPVccRetryThreshold value to 1.

CSCdu03975

Symptom: There is a noise problem with the CES PAM hardware version one.

Workaround: None.

CSCdu02569

Symptom: When slot 0 is configured as the ARP client, the client might release the SVC within one minute of a ping.

Workaround: Use the subinterfaces of slot 0 as the ARP client instead.

CSCdt96927

Symptom: The Internetwork Packet Exchange (IPX) statistics sometimes fluctuate when no traffic is flowing through the interface. The only affected functionality is IPX statistics.

Workaround: None.

CSCdt96722

Symptom: When video traffic is switched through an 8-port Gigabit Ethernet module in a Catalyst 8540 router, a high amount of jitter is seen.

Workaround: None.

CSCdt93866

Symptom: Sending a crafted control NTP packet might cause a buffer overflow.

Workaround: Include the "ntp access-group serve-only" line in the configuration of the router.

CSCdt91430

Symptom: Under a heavy load the switch router might misorder cells going out OC12 port adapter modules.

Workaround: Use the four-port OC12 modules designed for the Catalyst 8540.

CSCdt86869 (This defect is archived)

Symptom: When the routing table exceeds 50,000 entries and one or more eight-port Gigabit Ethernet interface modules are installed in the switch router, the CAM full condition might be seen. This condition will cause ports to stick.

Workaround: Perform an OIR of the module. The eight-port Gigabit Ethernet interface module is not designed to handle more than 50,000 entries.

CSCdt86157

Symptom: The SNMP polling of the MIB object atmVplOperstatus (in Virtual Path MIB) for VP tunnels shows that the VPL is DOWN, even when the tunnel is UP (as shown by the CLI).

Workaround: None.

CSCdt85859

Symptom: In bridging, the aging time of Ethernet process interfaces is always set to 300 seconds, despite what it is configured for.

Workaround: None.

CSCdt83249

Symptom: Even after enabling SNMP, the switch router might not be able to perform SNMP walk.

Workaround: None.

CSCdt81270

Symptom: The one-Port OC12 port adapter module might cause cell corruption. This will inevitably lead to packet corruption wherever segmentation and reassembly is performed to put the cells back into frames.

Workaround: None.

CSCdt80934

Symptom: When a static route is added to and deleted from an interface that already has a static route connected to it, the packets are process-switched.

Workaround: Enter the clear ip route command.

CSCdt78847

Symptom: On PVCs on a VP tunnel, attempts to configure usage parameter control (UPC) values other than "pass" might not succeed.

Workaround: Do not define the VP tunnel, just configure PVCs on the VPI.

CSCdt78491

Symptom: Online Diagnostic Snake tests might send ILMI traps when an interface becomes active. This can cause clients on other inter-faces to reset ILMI.

Workaround: Disable the snake test by entering the no diagnostics online snake command in global configuration mode.

CSCdt73634

Symptom: Cell memory might get stuck when ABR, IMA, and hierarchical VPs are combined.

Workaround: Enter the shutdown command on the IMA interface. Take the first link on the IMA interface out of IMA group. Enter the no shutdown command followed by the shutdown command on the interface. Enter the no shutdown command on the IMA interface.

CSCdt71010

Symptom: The ifTable Indexes might not match MIB-II table indexes.

Workaround: None.

CSCdt70190

Symptom: If a switch processor switch over occurs, the IMA interface will remain in a waiting state. After this, entering the shutdown command and then the no shutdown command on the IMA interface will bring it to the "going down" state.

Workaround: To avoid this issue, disable online diagnostics before a switch processor switch over.

CSCdt70110

Symptom: If a route processor switch over is done continuously more than two times by entering the redundancy force-failover main-cpu command or once entering the EHSA null_ptr command, the new primary route processor will issue the following error message continuously:

%FRPAM(pciread):returned error 0x2000000!
%FRPAM(pciread): pci addr 0x02080208! read failed!!
%FRPAM(pciread): time taken to read 0x02080208! is 8
loop_count 1

Workaround: An online insertion and removal of the FR port adapter will stop this error message.

CSCdt67260

Symptom: The switch router might crash when being polled by SNMP.

Workaround: None.

CSCdt62617

Symptom: The SNMP ccrCpuStatusChange traps are sent regularly with a ccrCpuStatus of ok(2) even though there is no change in the status of the CPU. This happens only when commands such as show running-config or write memory are entered.

Workaround: Disable the traps.

CSCdt62555

Symptom: When using PNNI, another vendor's equipment might send an invalid PTSE update. If the switch router receives one of these invalid updates, the PNNI neighborship might not re-establish.

Workaround: None.

CSCdt62215

Symptom: After resetting an E1 device connected to the CES port there might not be connectivity about Layer one.

Workaround: Enter the shutdown command followed by the no shutdown command on the CBR interface.

CSCdt60582

Symptom: Two adjacent ATM devices had problems with ILMI negotiation. The result of the ILMI negotiation is VPI/VCI range failure.

Workaround: None.

CSCdt53814

Symptom: An ARM port configured for transparent bridging and in blocking state might forward certain frames.

Workaround: Depending on the topology, the work-around might be to ensure that a non-ARM port is in blocking state. Where this is not feasible, you need to physically shutdown the ARM port that is in the blocking state.

CSCdt58148

Symptom: A switch router might show additional atm interfaces than the number of interfaces present in the chassis. This does not affect functionality.

Workaround: None.

CSCdt49005

Symptom: SVC signalling across a VP tunnel might not work after a reload.

Workaround: None.

CSCdt47492

Symptom: On the OC-3c port adapter module, ILMI might remain in the "waitdevtype" state after a redundancy fail over.

Workaround: If the problem is seen on port 1-3, bring up port 0. If the problem is seen on port 5-7, bring up port 4. If the problem is seen on port 9-11, bring up port 8. If the problem is seen on port 14-15, bring up port 12. The port can be brought up by connecting a loopback cable, or just by using that port.

CSCdt46026

Symptom: A switch router with OC3 port adapters and five Fast Ethernet interface modules might boot up with the following error message:

epif_aal5_fastsend: bad vcinfo This message may appear 100s
of times and slow down the boot process. Normal operation does not seem affected
once the 8500 has finished booting.

Workaround: None.

CSCdt44930

Symptom: When a switch router sends a tag distribution protocol (TDP) bind request and does not receive an answer, the TVC remains unconnected. This might cause scalability problems in large networks because over time these TVCs might use up a large number of resources.

Workaround: Add a timer to clean up the VCs.

CSCdt40530

Symptom: Switch routers running Cisco IOS Release 12.0(13)W5(19) or earlier might experience a memory leak when used with an NMS (Network Management System) running SNMP whenever it accesses PNNI tables.

Workaround: Turn off NMS polling of PNNI tables and instead use the CLI or determining any PNNI information.

CSCdt38728

Symptom: Online Diagnostic might run in the background and then stop suddenly with the following error message:

1d23h: %SCHED-2-EDISMSCRIT: Critical/high priority process Online Diagnostics may not dismiss. -Process= "Online Diags", ipl= 0, pid= 62

Workaround: Enter the diagnostics online snake command in global configuration mode to restart the online diagnostics.

CSCdt38604

Symptom: ILMI might not properly learn the ip addresses of peer switches. After entering the show atm ilmi-status command, the interface of the peer switch is learned but its ip address is not.

Workaround: None.

CSCdt24278

Symptom: The ARM might set the CLP of all cells to one when bridging is configured over a PVC. This happens for cells being transmitted over the 1483 PVC only.

Workaround: None.

CSCdt18467

Symptom: The port stuck message might log to the system log.

Workaround: None.

CSCdt17378

Symptom: The ATM uplink module might not support map list entries for its own IP address.

Workaround: None.

CSCdt15978

Symptom: The telnet response over an ISL trunk might be very slow. This is because small ISL frames (under 94 bytes) are not padded, and some devices drop ISL frames that are smaller than 94 bytes.

Workaround: None.

CSCdt13517

Symptom: The switch router might stop switching some VCs and log error messages like the following:

12:37:34.793: ATMSIG(12/1/0:0 0,37 - 274610/00): (vcnum:0) XConnected failed To Jan 9 12:37:34.793: ATMSIG(12/0/1:0 0,268 - 398903/00): (vcnum:0) Jan 9 12:37:34.793: ATMSIG: CONNECTION MANAGER/CAC Xconn install request Port A - (12/1/0) : 0 vpi = 0; vci = 37 Port B - (12/0/1) : 0 vpi = 0; vci = 268; new vpi = 0; new vci = 268 existing vpi/vci for leg B Jan 9 12:37:34.793: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL

Workaround: Reload the switch router.

CSCdt10494

Symptom: An ATM router module interface indicates outgoing packets when that interface is administratively down.

Workaround: None. This does not impact functionality.

CSCdt10434

Symptom: When there is a lot of signaling svc setup and teardown on an NNI tunnel, interface calls might fail with a vpi/vci collision.

Workaround: Use a regular interface (no tunnels).

CSCdt09229

Symptom: The switch router might lose traffic on its LANE/1483/1577 interfaces on an ARM. Frame interfaces (like Fast Ethernet) or non-lane interfaces on ARM (with configured PVCs) pass traffic without any problems.

Workaround: Perform an OIR on the ARM or reload the switch router.

CSCdt05390

Symptom: IP and IPX routing over BVI on an 8-port Gigabit Ethernet port or a port channel might fail when the 8-port Gigabit Ethernet interface is removed from the bridge group.

Workaround: None.

CSCdt05348

Symptom: Cell loss on PVC connections occurs when removing the active route processor.

Workaround: Entering the redundancy prepare-for-cpu-removal command might prevent any cell loss outage from affecting established PVCs.

CSCdt05168

Symptom: When using a 155-Mbps port adapter module, the show controller command output will list all port mediums as SM_IR_+.

Workaround: None.

CSCdt04356

Symptom: On a switch router performing the Frame Relay/ATM Network Internetworking function, when the Local Management Interface (LMI) indicates a PVC is inactive on an NNI interface, this information is not propagated by the Frame Relay/ATM software.

Workaround: None.

CSCds95813

Symptom: A system running PNNI with Cisco IOS release 12.0(7)W5(15c) will reject an ATM call SETUP if the setup includes the 5a information element coded with associated signaling, explicitly the VPCI and any VCI.

If another ATM switch sends a setup that includes the 5a information element coded with the associated signalling, explicit VPCI and any VCI, the system will release the call with cause code 35: requested VPCI/VCI not available.

Call setups that include the 5a information element coded with the associated signalling, explicit VPCI, explicit VCI signalling, including those made by Cisco ATM switches are not affected by this problem.

This interoperability issue exists between Cisco ATM switches and other vendor's switches that do not explicitly request the VCI value in the call SETUP.

Workaround: None.

CSCds88973

Symptom: The port stuck detection and recovery mechanism might not work if one of the channels of the ARM port gets stuck.

Workaround: None.

CSCds85282

Symptom: Power-on diagnostics hang, and the IOS is unable to boot, when ARM, Fast Ethernet, and OC-12 modules are installed in the same chassis.

Workaround: None

CSCds78385

Symptom: IPX traceroute might skip the middle hop when the middle router is the Catalyst 8540 switch router.

Workaround: None.

CSCds74179

Symptom: The RMON for the 8-port Gigabit Ethernet interface module might not work.

Workaround: None.

CSCds69507

Symptom: When an OIR is performed on an ARM module, the HSRP configuration might get lost.

Workaround: None.

CSCds57303

Symptom: The ATM User-Network Interface (UNI) does not include a cumulative round-trip time parameter in the ABR call setup. This situation might cause interoperability issues with different vendor products.

Workaround: None.

CSCds51004

Symptom: The circuit emulation service (CES) address does not change when the switch router address is changed. When the global switch ATM address prefixes are added or deleted (via the atm address command), addresses registered for existing CES circuits are not changed.

Workaround: None.

CSCds49175

Symptom: The show hardware detail command does not show the actual version of the FPGA for any of the daughter cards. This shows the version of the FPGA motherboard which is misleading.

Workaround: None.

CSCds48921

Symptom: The atm arp-server nsap command is removed from the running configuration upon reloading the switch.

The copy startup-config running-config command will restore the original configuration.

Workaround: None.

CSCds44607

Symptom: If you save the running configuration, you may see the following error:

ROUTER# copy run start
Destination filename [startup-config]?
startup-config file open failed (File table overflow)

This happens when you issue a write mem command or a copy running-config startup-config command. Issue a show file command to show the 127 entries of private configuration.

Workaround: Save the running configuration in a file, reload the router, and then issue a write mem command or copy running-config startup-config command.

CSCds43859

Symptom: Although packets are being sent out from an ATM OC-12 interface module, the 5-minute output rate shown using the sh int atm command indicates 0 bits/sec output. This is not consistent with the output rate shown under the sh atm traffic command.

Workaround: None.

CSCds42545

Symptom: A simultaneous encapsulation change on both sides of a link when the force-link up mode is used presents a 50 percent chance of bringing the line-protocol down. This problem does not happen when encapsulation change is done one side at a time. Problem is usually not seen when auto-negotiation is enabled.

Workaround: Issue a shutdown and no shutdown to bring the line protocol up.

CSCds40925

Symptom: When the show atm interface traffic command is entered on a subinterface, the total number of cells that has passed might show incorrectly as zero.

Workaround: None.

CSCds40705

Symptom: The Xconnect setup fails for unidirectional TVC if there is another one with different direction and same vpi/vci on particular interface of the Catalyst 8540 MSR. This can be seen only if VC merge is disabled.

Workaround: None.

CSCds39855

Symptom: When the primary clock source is in the "unlockable" state, and the clock fails over to the secondary clock, the router never reverts to the primary clock source, even when the connection is clean and the clock source is present.

Workaround: None.

CSCds39323

Symptom: The output of the command show epc if-entry is limited to 20 characters. This limits the command from showing specific port information when the module or slot combination causes the output to go beyond 20 characters. For example, when Gigabit Ethernet interfaces are installed in slot 10 or greater, the output is truncated.

Workaround: None.

CSCds38890

Symptom: The present configuration does not work properly for frame reject (FRMR) and acknowledgement timeout messages. Occasionally a file transfer works normally, but most of the time it does not.

Workaround: None.

CSCds38053

Symptom: Traffic pointing to an unknown route goes to the route processor even with ip unreachable disabled on the Gigabit interface input port. The traffic is dropped if the input port is an Ethernet interface port and ip unreachable is disabled.

Workaround: None.

CSCds36571

Symptom: Ports get stuck on a Gigabit interface when booting with 12.1(1.6)W6(25) image. The same cards boot up fine with 12.1(1.6)W6(24).

Workaround: None.

CSCds35157

Symptom: Crash after issuing a clear counters command in get_pif_no function.

Workaround: None.

CSCds33901

Symptom: When the reset button is pushed, the switch router might not boot the main-image, and eventually goes into ROMMON.

Workaround: None.

CSCds29865

Symptom: When HSRP is configured on the eight-port Gigabit Ethernet interface module, HSRP connectivity might be disrupted after a remote link failure is followed by a link restoration.

Workaround: Configure another HSRP group with a higher number and move the standby configuration to that group.

CSCds29781

Symptom: The output errors counter is incorrect on Gigabit Ethernet show interface command. They have a high value 4xxxxxxxxx and a clear counter command does not change it back to 0. This value can increase or decrease over time.

Workaround: None.

CSCds28912

Symptom: IP traffic is not sent over PVC if AAL5 MUX encapsulation is used on a point-to-point subinterface on the Catalyst 8540 MSR. If the deb atm errors command is enabled, the following error messages will appear:

point-to-point interface does not have a VCD

Workaround: None.

CSCds28286

Symptom: The route processor redundancy may fail if you have both PVC and bridging configured on the ARM sub-interface.

Workaround: None.

CSCds13037

Symptom: The system is not completing a route processor failover. The secondary route processor (redundant), as it assumes function from a failover will display the following error message:

%Secondary CPU Detected
remove_conn_from_fabric: Error close party failed for . . .

This does not affect operation of the system but will prevent the secondary route processor from booting successfully if the primary crashes.

Workaround: None.

CSCds12640

Symptom: On an MSR switch router with enhanced Gigabit interface cards, the switch router crashes when loading a CSR image because of the CES card in the switch router.

Workaround: None.

CSCds09613

Symptom: IPX load-balancing on IPX packets sourced from enhanced Gigabit Ethernet ports or sent out of ATM uplink ports will work only if IPX max-paths are set to 1 or an even value (i.e. 2, 4 or 6). An odd value of 3 or 5 can cause some of the IPX packets to not go out of the ATM uplink ports. This problem is seen only with SVCs over 1483 not PVCs with 1483.

Workaround: When IPX packets are sourced from enhanced Gigabit Ethernet ports, set the IPX maximum paths to 1, 2, 4 or 6. If there are an odd number of paths, change the administrative weight of one path so that there are always an even number of equal cost paths.

CSCds09323

Symptom: The ATM router module (ARM) does not strip the Ethernet pad when switching data from Ethernet to ATM. This may occasionally lead to connectivity issues since some end-systems do not expect to see the pad.

Workaround: None.

CSCds08999

Symptom: When an enhanced Gigabit Ethernet interface module sends out ISL packets with packet sizes 1531 to 1548, the output error counter on the egress port increases.

Workaround: None.

CSCds08237

Symptom: The hierarchical VP tunnel configuration fails on a WAI-OC3-1S3M mixed mode port adapter module when it is in slot 0 subslot 1 of the C85MS-SCAM-2P carrier module. Slot 0 subslot 0 of the carrier module can either be empty or have another card in it, and hierarchical VP tunnel configuration will still fail. However, if the mixed mode pam is inserted in slot 0 subslot 0 of the carrier module, then the hierarchical VP tunnel can be configured.

Workaround: None.

CSCds04747

Symptom: The switch router might be vulnerable to the successful prediction of TCP Initial Sequence Numbers. This vulnerability only applies to the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device, in transit between two other hosts.

Workaround: Update to Cisco IOS Release 12.0(13)W5(19c).

CSCds04387

Symptom: When IPX packets are sourced from fast Ethernet interface based ports and sent out of ATM uplink ports, IPX load balancing will work only if the IPX max-path is set to 2. A value greater than 2 can cause some of the IPX packets to not go out of ATM uplink ports. This problem is seen only with SVCs over 1483 not with PVCs over 1483. However, if all IPX traffic is sourced only from enhanced Gigabit interface ports then this problem is not seen. Six-path load balancing will work correctly.

Workaround: When IPX packets are sourced from fast Ethernet interface based ports, set IPX max-paths to less than or equal to 2.

CSCds03229 (This is archived)

Symptom: A bus error that occurs at PC 0x6014A9E0 causes the Catalyst 8540 MSR to crash. This occurs when the router is polled for ATM data via SNMP.

Workaround: None.

CSCds00513

Symptom: When serial interfaces on a Frame Relay/ATM internetworking port adapter are oversubscribed, and significant data bursts occur simultaneously on multiple VCs on multiple serial interfaces, one serial interface might get stuck.

Workaround: Enter the hw-module slot/subslot command.

CSCds00193

Symptom: The ifSpeed is reported as 100MB even when the auto-negotiation results in 10MBit.

Workaround: None.

CSCdr97847

Symptom: No SNMP trap exists corresponding to the following syslog message:

%ATM-4-ILMIKEEPALIVEFAIL.

Workaround: Enable syslog traps on switch to capture these failures

CSCdr96613

Symptom: After replacing an ATM 155-Mbps multimode port adapter with an ATM 155-Mbps single-mode port adapter, the SNMP agent might not correctly refresh the AtmIftable: it still returns the old ciscoAtmIfPortType information for the new module. Stopping SNMP and then restarting the SNMP agent does not correctly refresh the table.

Workaround: Reload the switch router.

CSCdr93044

Symptom: The Gigabit Ethernet port on the eight-port Gigabit Ethernet interface module comes up as unshutdown after an OIR.

Workaround: None.

CSCdr91799

Symptom: Due to a hardware limitation, any packets larger than 6K could potentially cause a port stuck. After a port is stuck, the normal port stuck recovery mechanism applies.

Workaround: Configure a port-stuck reload.

CSCdr91196

Symptom: The output rate displayed in the show interfaces command on the POS interface can be artificially high at times.

Workaround: Issue the clear counters command or the shutdown and no shutdown commands.

CSCdr91099

Symptom: The default network over a POS link might not work when the outgoing interface is specified instead of the next hop interface.

Workaround: Specify the next hop interface.

CSCdr86386

Symptom: When a Catalyst 5500 connected to a Catalyst 8540 CSR is powered down, the BVI interface does not receive EIGRP and OSPF multicast hello packets.

Workaround: None.

CSCdr86168

Symptom: The system crashes when more than 80 VCs are configured on an ATM uplink port and the port is added to a bridge group. Avoid this configuration.

Workaround: None.

CSCdr86044

Symptom: The release message uses the wrong cause and diag information.

Workaround: None.

CSCdr83546

Symptom: clear atm vc option specifies VCDs from 1 to 4095 only. Therefore, any SVC with a VCD greater than 4095 cannot be cleared using this command.

Workaround: None.

CSCdr83138

Symptom: Enhanced Gigabit Ethernet ports learn MAC addresses of all zeros for packets with source MAC addresses with all zeros. This does not cause any problems.

Workaround: None.

CSCdr82616

Symptom: If you have more than 900 VCs on any interface or subinterface on the Gigabit Ethernet port with ATM uplink interface modules and you perform an online insertion and removal (OIR), a BROUTE VC release/setup failure will be indicated.

Workaround: None.

CSCdr82453

Symptom: The routing flag is not set and remains off after unconfiguring the bridge group on the system. This is only on ATM uplink ports.

Workaround: Issue the shutdown and no shutdown commands.

CSCdr81329

Symptom: When the network clock module quality is not accurate the NCDP will automatically disable. It is normal behavior of ncdp.

You can check the ncdp status with the following:

switch# show ncdp port atm2/0/0
port data --(35)-----ATM2/0/0--------------
port_id : 35
state : disabled
^^^^^^^^

Workaround: None.

CSCdr80770

Symptom: When the ingress is a fast Ethernet interface, and the egress is an ATM uplink interface and is one of several parallel paths to a destination IPX network, shutting down this interface will cause the packets sent to this destination to use the first of the remaining parallel paths.

Workaround: The correct path will be chosen after issuing the clear ipx route* command.

CSCdr80267

Symptom: If HSRP over BVI is configured and a standby MAC address is explicitly configured on the BVI, this MAC address will not be reflected in the patricia table of the interface.

Workaround: None. The recommended option is to not use a standby MAC address and let the system choose the address.

CSCdr80160

Symptom: The two-port Gigabit Ethernet is part of a port channel, which has HSRP configured on it. Even after the two-port Gigabit Ethernet is removed from the port channel, the HSRP MAC address is retained.

Workaround: Issue the shutdown and no shutdown commands, add an IP address, or add the MAC address to a bridge group to delete the entry.

CSCdr78226

Symptom: A Catalyst 8540 with an ARM module, might take a software forced crash when attempting to establish EIGRP adjacencies.

Workaround: None.

CSCdr77057

Symptom: The ATM router module microcode for RFC1483 did not have the ability to understand CLNS topology updates forcing the card to drop packets. This also effected the IS-IS routing updates.

Workaround: Upgrade to the Cisco IOS release 12.0(11)W5(19).

CSCdr76566

Symptom: There is no support for SONET MIB objects in ATM uplink module.

Workaround: None.

CSCdr75370

Symptom: After issuing the shutdown and no shutdown commands on an interface that is part of a bridge group, sometimes the BCAST VC becomes zero.

Workaround: Issue the shutdown and no shutdown commands or remove the interface from the bridge group and add it back to restore the BCAST VC.

CSCdr74263

Symptom: Subinterfaces with the same VLAN color cannot be present in different bridge groups. This check is done when a bridge group configuration is being created or removed, not when the encapsulation is being changed.

Workaround: None.

CSCdr74119

Symptom: The router reloads when handling internetworking packet exchange (IPX) access-logging-messages. This situation may still occur if access-logging is not enabled.

You may exceed the 200 IPX network limit when the hardware is activated after being removed. When the hardware is reactivated, the interfaces that were not counted while the hardware was removed cause the limit to exceed.

Workaround: None.

CSCdr72714

00:02:08: %SYS-2-GETBUF: Bad getbuffer, bytes= -2008487331 Process= "Init", ipl= 0, pid= 2 -Traceback= 6006D014 6016239C 60335DE4 60335FB8 60336110 60336350 60029724 60099364 60099350

Symptom: The message above might appear during bootup. The system recovers from this.

Workaround: None.

CSCdr71493

Symptom: The Gigabit Ethernet interface is part of a port channel; one of the port channel subinterfaces is a member of the bridge group. The BVI MAC address is retained on the interface even after it is removed from the bridge group.

Workaround: Issue the no mac-address command under the interface.

CSCdr70086

Symptom: The IP adjacencies are not being cleared from the Gigabit Ethernet card quickly enough.

Workaround: Upgrade to the Cisco IOS release 12.0(10)W5(18c) software or later.

CSCdr69541

Symptom: Option access-list under the show controllers command returns nothing when the interface is configured for bridge address access-list. Option mac under the show controllers command for the enhanced Gigabit interface port returns nothing when it finds a match in the Layer 2 database.

Workaround: None.

CSCdr69116

Symptom: MAC addresses are missing in the two-port Gigabit Ethernet port part of the bridge group when many MAC addresses are learned over the POS link and the POS link goes down.

Workaround: None.

CSCdr69004

Symptom: When auto negotiation is disabled on an enhanced two-port Gigabit Ethernet port, it is up even if the GBIC is not present.

Workaround: None.

CSCdr68921

Symptom: The CSR image recognizes the ATM router module and downloads the ATM router module micro-Code.

Workaround: None.

CSCdr68605

Symptom: The following message may appear when an incorrect signaling packet is transmitted by the peer device:

SYS-2-BADSHARE: Bad refcount in datagram_done

This may lead to memory corruption.

Workaround: None.

CSCdr68425

Symptom: Cannot create soft VC with 95% of PVP

The calculations for determining the limits of PCR and SCR that can be used for a VBR-NRT VC traversing through a VP tunnel using the CAC algorithm at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/atm/c8540/wa5/12_0/3a_11//atm_tech/rm.htm#xtocid2419

This holds true for PVCs but not soft VCs.

Workaround: None.

CSCdr67623

00:04:37: %ALIGN-3-CORRECT: Alignment correction made at 0x60674830 reading 0x62017DB3

Symptom: The alignment correction might occur with the clear bridge or show bridge commands with the ATM uplink. The system recovers from the alignment correction.

Workaround: None.

CSCdr66855

Symptom: If the peer device has a non-HP Gigabit interface converter (GBIC) and is not seated properly, the "Optical Detect" LED will be OFF on this device.

Workaround: Enter the shutdown and no shutdown commands or reseat the GBICs after a power cycle.

CSCdr66338

Symptom: The static bridge command might disappear from the running configuration.

Workaround: None.

CSCdr65079 (This defect is closed)

Symptom: When the module is removed from the switch, the interfaces continue to show as inserted and also the IDB's are not deleted. The problem occurs with different kinds of modules in different slots.

This was noticed when a module is inserted into a slot and another is removed almost immediately. This is not seen when a good amount of time is given between the act of insertion and removal of the modules.

To prevent this, before inserting a new module into the switch, wait 2 minutes after OIR.

Workaround: None.

CSCdr63345

Symptom: The ATM router module cannot remove interfaces bvi8 thru bvi11 and cannot unconfigure bridge groups 8 thru 11. This problem occurs with a configuration of 20-30 bridge groups. Some bridge groups which had BVIs enabled could not be unconfigured with the command line interface (in this case it was bridge groups 8 thru 11). The command for removing a particular BVI is not recognized, and the bridge-group could not be deleted.

This does not affect any bridging or routing functionality on the device. It is a configuration issue only.

Workaround: None.

CSCdr62978

Symptom: The HSRP interface does not preempt after the shutdown and no shutdown commands are entered.

An HSRP interface configured for "preempt" might not become active after reset. No error message is given.

Workaround: Set higher priority for "preempt" interfaces as a second decision instance.

CSCdr61171

Symptom: PIM: Watchdog timeout in pim_mps_idle_vc().

Workaround: None.

CSCdr59877

Symptom: The output of the show interface ethernet command might display a `lost carrier' count that is the same as that for the collision counter on that Ethernet interface. This is a counter error only, and does not actually indicate a lost carrier.

Workaround: None.

CSCdr59783

Symptom: Appletalk fails when bridged between an 8-port gig and 2-port Gigabit Ethernet card on the Catalyst 8540 MSR.

Workaround: Upgrade to IOS release 12.0(4a)W5(11a) or later.

CSCdr59347

Symptom: When two Catalyst 8540 CSRs with two-port Gigabit Ethernet interface modules are connected back-to-back, packets are lost. On one side the counters might show input and output increasing, but the other side shows only output packets increasing. The Address Resolution Protocol (ARP) from the other side is lost, and the ability to ping the other side is lost.

Workaround: Reset the GBIC.

CSCdr58521

Symptom: On the ATM uplink any packet routed on a point-to-point interface will be routed by the route processor.

Workaround: Do not configure point-to-point subinterfaces on the ATM uplink.

CSCdr58338

%LSS-4-INTERNAL_WARNING: lss_record_ri_ingress: Illegal channel %d

Symptom: The above message might appear when changing the trunk encapsulation type of a Gigabit EtherChannel (GEC) from ISL to 802.1q, when GEC is configured for novell-ether encapsulation and ports are receiving IPX wire speed traffic. No functionality problems are observed.

Workaround: None.

CSCdr56798

Symptom: Due to a hardware limitation, any packets larger than 6K could potentially cause a port stuck. After a port is stuck, the normal port stuck recovery mechanism applies.

Workaround: None.

CSCdr56326

Symptom: When reloading a new image into the enhanced two-port Gigabit Ethernet interface module the ATM uplink enhanced Gigabit interface appears to have been reset. The enhanced two-port Gigabit Ethernet interface module download shows no effect on the ATM uplink.

Workaround: None.

CSCdr55333

Symptom: If the weighted-fair queueing is configured on an ATM IMA interface of a Catalyst 8540 MSR, the system may go into an infinite loop generating traceback messages.

Workaround: Do not configure.

CSCdr54231

Symptom: Notifications sent or received are only visible if the debug ip bgp command is configured. This might limit the ability to diagnose problems.

Workaround: None.

CSCdr54230

Symptom: When running Border Gateway Protocol (BGP), the BGP peers of the receiving border router might detect a mismatch in the code, and issue a notification message to reset their session. This does not affect the receiving border router.

Workaround: None.

CSCdr52546

Symptom: When reprogramming the switch processor(s) the Catalyst 8540 CSR might crash. No connections should be installed after reprogramming until the system reboot is complete. However, some interface modules create connections before the system reboot is complete so only the interface modules are recognized in the system crash.

Workaround: None.

CSCdr52527

Symptom: There is no instance of ACL card in the MIB table.

Workaround: None.

CSCdr51414

Symptom: In a switch equipped with circuit emulation service cards, the shutdown of a CBR interface does not affect the device connected to it.

Workaround: None.

CSCdr50435

Symptom: IP PIM Sparse-Mode using multipoint signaling over ATM can fail when the PNNI path is switched to the redundant link.

Workaround: Upgrade to Cisco IOS release 12.0(10)W5(18c) or later.

CSCdr49975

Symptom: Cannot set ifAdminStatus object on CES interfaces. Attempts to set ifAdminStatus result in the following:

vvv
Error code set in packet - Bad variable value. Index: 1.
^^^

Workaround: None.

CSCdr48700

Symptom: When more than one loopback interface needs to be configured, the interfaces are assigned the incorrect number, so they are all created as Loopback0. The interfaces cannot be removed.

Workaround: None.

CSCdr48489

Symptom: Under heavy multicast traffic, cells might stick in the switch fabric. This happens when a race condition occurs in the switch processor and the output VC (OVC) is not present in the active list or idle list. In this situation, the OVC is never taken up for further scheduling, and all the cells in the VC are stuck.

Workaround: Enter the clear ip multicast-routing command or enter the shutdown/no shutdown commands to the root interface.

CSCdr46754

Symptom: With an encapsulation change on a two-port Gigabit Ethernet interface module, the interface no longer sends packets. It seems that it is receiving packets and sending packets to the route processor when necessary, but the packets are not sent.

Workaround: None.

CSCdr45513

Symptom: When the switch router is reloaded, you must enter the shutdown command followed by the no shutdown command on the CBR ports in order to activate the CBR ports.

Workaround: None.

CSCdr44798

Symptom: Routed traffic does not pass through a port on the 8-port Gigabit Ethernet card when the port is in blocking mode for bridged traffic.

Workaround: None.

CSCdr43610

Symptom: When two 8540 CSR switch routers are directly connected by a two-port Gigabit Ethernet interface module, a reset of one switch router does not cause the remote switch router's interfaces to go down too. The problem is caused by the reset switch router's interfaces not going down, so remote interfaces do not go down.

Workaround: Physically remove the cable from the ports or issue the shutdown command.

CSCdr43326

Symptom: When running the Cisco IOS release 12.0(7)W5(14.74) software on a switch, it is possible that the atmVcCrossConnectAdminStatus entries will disappear.

Workaround: None.

CSCdr43159

Symptom: When the Catalyst 8540 CSR has both Protocol Independent Multicast (PIM) joins and IGMP joins coming in, one of the interfaces in the outgoing interface list of the IOS multicast table might not forward traffic. This is caused by a disconnect in the sequence of events between IOS multicast code and the Catalyst 8540 CSR specific light stream inter process communication subsystem (LSS) multicast code.

Workaround: Enter the clear ip multicast-routing command and configure static multicast groups on the interfaces sending PIM joins.

CSCdr41940

Symptom: After a route processor switchover, the microcode for a Fast Ethernet (FE) interface module might not download successfully. This failure occurs infrequently but causes the interfaces on the failed FE interface module to be unusable.

Workaround: Remove and reinsert the affected FE interface module.

CSCdr40560

Symptom: In some instances, an ATM interface on a Catalyst 8540 MSR may get stuck in a going down state.

Workaround: None.

CSCdr39060

Symptom: After a switch processor switchover, the microcode for an 8-port Gigabit Ethernet (GE) interface module might not download successfully. You will see the following error message:

epif_port_write_mii: Timeout for response message GigabitEthernet

This failure occurs infrequently but causes the interfaces on the failed 8-port GE interface module to be unusable.

Workaround: Enter an skmgmt reset command. When this command is entered, you might see BROUTE-VC SETUP FAILURE messages. These messages are harmless and can be ignored.

CSCdr38540

Symptom: When issuing the shutdown/no shutdown command on an ATM interface with a large number of VCs, the route processor utilization stays high for a long period of time. For example, for an 8K VC, the route processor stays high for around 720 seconds and for 4K VCs, it is around 300 seconds.

Workaround: None.

CSCdr38522

Received malformed TLV.

Symptom: Sometimes the above message is seen.

Workaround: None.

CSCdr37235

Symptom: On bootup, the following warning message may appear:

IPC-5-NULL:Recd. msg Dest Port

It has no affect on the switch.

Workaround: None.

CSCdr36952

Symptom: The switch router will crash and hang when the ip http server command is configured and a browser connects to http://<router-ip>/%%. This defect can be exploited to produce a denial of service (DoS) attack. This information has been announced on public Internet mailing lists which are widely read both by security professionals and by security "crackers," and should be considered public information.

Workaround: Disable the IP http server with the following command:

no ip http server

Alternatively, the administrator can block port 80 connections to the switch router via access lists or other firewall methods.

For further information, refer to the security advisory available at http://www.cisco.com/warp/public/707/advisory.html

CSCdr35301

Symptom: The values for ifInOctets wrap every 15 to 30 seconds on ATM interfaces with very little traffic. The wrapping occurs when the value is about 3,000,000 octets.

Workaround: None.

Workaround: None

CSCdr32957

Symptom: When configuring region sizes you are not considering the ACL region size when checking for the total size. Configuration allows regions sizes exceeding total Tcam size. No error message is printed at the time of configuration but upon next boot you get the following error messages:

ACL cannot be enabled on GigabitEthernet0/0/0 - insufficient TCAMAvailable: 24 Configured for ACL: 2048 Use sdm access-list command to reconfig

Workaround: None.

CSCdr30765

Symptom: The ip cef command does not re-enable the CEF switching on the Catalyst 8540 when previously disabled due to lack of memory. The Catalyst 8540 requires CEF switching but this can become disabled if there is insufficient memory available. When insufficient memory is available, the following message appears:

"%FIB-2-FIBDOWN: CEF has been disabled due to a low memory condition.

Workaround: None.

CSCdr30421

Symptom: Multicast statistics might show an incorrect kilobits per second (kbps) rate.

Workaround: None.

CSCdr29169

Symptom: After upgrading from Cisco IOS Release 12.0(5)W5(13) to Cisco IOS Release 12.0(5)W5(13b) code, CSR no longer boots. Restoring the older code corrects the problem. The crash occurs after the file is read. Removing the configuration text file from the TFTP server prevents the router from crashing. If the router is booted from the NVRAM configuration and the command copy tftp running then is issued, the router will crash. copy startup running does not crash the system.

Workaround: None.

CSCdr26204

Symptom: On a switch using the ospf area-range command, the summary link state advertisement created might get stuck in the database and not be flushed after the command is removed.

Workaround: None.

CSCdr26034

Symptom: XPIF modules are not supported.

Workaround: None.

CSCdr25535

Symptom: An ima_failure_trap might not be generated when an IMA group gets deleted and the group state change might not be sensed by the switch processor.

Workaround: None.

CSCdr23428

Symptom: When ports on the eight-port Gigabit Ethernet interface module are connected to Ethernet interfaces, you get frames with new MAC addresses. Because the ports on the 8-port Gigabit Ethernet interface module send ca-updates to the Cisco IOS, the show bridge command displays the learned MAC addresses. Although the 8-port Gigabit Ethernet interface module has incrementing SkIPC Rx failed counters, there is no side effect. The format of show skmgmt stats command has been modified to take care of this problem.

Workaround: None.

CSCdr22194

Symptom: When the existing two-port Gigabit Ethernet interface module is replaced with the enhanced Gigabit Ethernet interface module by online insertion and removal (OIR), the running configuration that is part of the existing two-port Gigabit Ethernet interface module will not be available for the enhanced Gigabit Ethernet interface module.

Workaround: Save the configuration to NVRAM before doing an OIR of the two-port Gigabit Ethernet interface module with the enhanced Gigabit Ethernet interface module. Complete the OIR of all two-port Gigabit Ethernet interface modules with the enhanced Gigabit Ethernet interface modules. Enter the reload command to get the configurations of the two-port Gigabit Ethernet interface module for the enhanced Gigabit Ethernet interface module. The other option is to save the configuration to a TFTP server, edit the configuration so that only those relevant to the replaced two-port Gigabit Ethernet interface module is retained, and do a copy of this edited configuration to the running configuration.

CSCdr20326

Symptom: DS3 Frame Relay port adapter firmware stops forwarding traffic when 16 channel groups are oversubscribed. The egress port hangs when it receives a frame with a size that is an integral multiple of 48 bytes.

Workaround: None.

CSCdr16404

Symptom: The standby switch processor (SP) does not take over when an active SP fails to initialize during system bootup.

Workaround: None.

CSCdr15370

Symptom: The ATM route processor might not forward IP traffic to the default route.

Workaround: None.

CSCdr14673

Symptom: When the switch is rebooted, at the point when it is going down, the console is flushed with the following messages:

Note: A random Spanning Tree Bridge Identifier address of 0000.0c00.9a70 has been chosen for Bridge Group 12 since 00:00:39: %SYS-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.

There is no mac address associated with the selected interface.
00:00:40: %SYS-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.

These messages have no effect on the switch.

Workaround: None.

CSCdr13429

show version command displays an extra ATM interface.

Symptoms: The number of ATM interfaces is displayed as one more than the actual hardware present in the system.

Workaround: None.

CSCdr07165

Symptom: A bus error exception might occur when adding parties to a root connection.

Workaround: None.

CSCdr06756

Symptom: If a peer system is reloaded after a route processor switchover, all traffic into the port might be dropped. This prevents well-known VCs from coming up.

Workaround: Enter the shutdown command. To restart the disabled interface, enter the no shutdown command.

CSCdr06375

Symptom: CBR soft VPs do not come up on route processor switchover.

Workaround: None.

CSCdr06198

Symptom: An IPX packet containing the wrong length in the IPX header and requiring an encapsulation change causes the ingress port to hang. The switch router must be reloaded.

Workaround: None.

CSCdr02365

Symptom: The show bridge command might not show all interfaces and the show bridge verbose command might not show all interfaces and hash entries. Entries are not displayed until they are "learned" when traffic is passed through them. If no traffic is ever passed, the entries will not be displayed.

Workaround: None.

CSCdr01726

Symptom: The Interim Local Management Interface (ILMI) status of shaped and hierarchical tunnel subinterfaces that are down (not shutdown) may remain in the restarting state after issuing a shutdown/no shutdown command sequence.

Workaround: Enter a shutdown/no shutdown command sequence on the main interface of the subinterface, or bring the interface up by connecting it to a peer system.

CSCdr00623

Symptom: Soft PVCs might be disabled on subinterfaces.

Workaround: None.

CSCdr00483

Symptom: When snooping is enabled on an ATM or ATM-P port, ATM PVC deletion might fail. If the deletion fails, the system does not recognize the ATM PVC deletion failure and deletes the Frame Relay PVC. This causes the ATM PVC and Frame Relay PVC to go out of sync.

Workaround: Before deleting the Frame Relay PVC, disable snooping on the ATM port.

CSCdr00463

Symptom: The show controller command does not display loopback configurations.

Workaround: None.

CSCdp97152

Symptom: When running 12.0 code with UNI 3.0, the Catalyst 8540 MSR may fail to send poll PDU's. This can result in a no_response_timer expiration and flapping of the sscop link.

Workaround: Configure UNI 3.1 on the link.

CSCdp95194

Symptom: A switch configured for MPLS (tag switching) and running the Cisco IOS 12.0(9) maintenance software release does not correctly increment counters on outgoing TVCs, although the data are being correctly sent out of the TVC.

Workaround: Upgrade to 12.0(4a)W5(11a) or higher.

CSCdp94469

Symptom: Operation, administration, and maintenance (OAM) pings might not work after a route processor switchover.

Workaround: None.

CSCdp94304

Symptom: Sometimes a MAC address learned over a port channel might not be removed from the IOS bridge table, but the entry might age out from the port channel. IPC might not be generated correctly to delete the MAC from IOS. This does not lead to incorrect routing of the packets as the packets are switched by the interface module and the table is consistent in the interface module.

Workaround: Issue the clear bridge group command.

CSCdp94120

Symptom: Under heavy traffic, if an encapsulation change (for a VLAN) is attempted on a 2-port Gigabit Ethernet interface module, the change might fail because of a microcode download failure.

Workaround: Shutdown the port (or port channel and all members of the port channel) when an encapsulation change is needed on Gigabit Ethernet ports or GEC. Make the encapsulation change, and then bring the port back up (no shutdown).

CSCdp94088

Symptom: When a snooping interface that is a higher card/subcard than the snooped interface (for example, interface ATM 0/1/1 snooping interface ATM 0/1/0), the snooping interface might be in an up state instead of in a snooping state. In addition, some of the snooping VCs might not be restored. When entering the shutdown command, the high-order snooping interface might get stuck while in the going down state.

Workaround: None.

CSCdp93731

Symptom: When OAM is enabled globally and ATM and IP traffic is in the switch, a crash might occur during route processor switchover.

Workaround: None.

CSCdp93395

Symptom: The ATM interface might show different line codes after a switch processor switchover.

Workaround: Use the show controller command to find the correct line code, which is listed under the line code violation (lcv) count.

CSCdp91740

01:34:29: %TBRIDGE-4-GIANT: Giant received on Port-channel1, 1504 exceeds 1500 DA 00d0.583f.1b47 SA 0090.214f.9047 [0x08004500]

Symptom: The above message might be seen with trunk interfaces configured in a bridge group with BVI after the clear bridge group or clear bridge command is issued. This is a transient state and the system recovers quickly.

Workaround: None.

CSCdp91190

Symptom: Packets coming in on a native VLAN being bridged to a port channel are dropped at the route processor. Untagged packets coming in on an 802.1Q trunk are associated with the native VLAN. Because of microcode limitations of the interface modules, the untagged packets are passed to the route processor to be routed or bridged. Consequently, we recommend that native VLANs not be used for network traffic and that they be limited to overhead traffic that terminates at the route processor (such as routing updates and CDP).

Workaround: Configure the traffic on a non-native VLAN.

CSCdp90216

The following traceback message appears:

%SK-7-ASSERT: Assertion Failure... Cant find port channel idb...

Symptom: Sometimes the above message appears when 8-port Gigabit Ethernet interfaces are added to port channels.

Workaround: None.

CSCdp88264

Symptom: A no loopback sonet-terminal command entered on an OC-48c interface does not bring the interface down even when no cable is connected to the port.

Workaround: Use the shutdown command to bring down the interface.

CSCdp86120

Symptom: When a port is temporarily stuck (such as egress starvation for a slightly extended period of time) there might be a memory leak. This happens very rarely when a port is temporarily stuck repeatedly.

Workaround: Schedule a reboot when the available memory goes down to a very low value. This caveat is fixed in Cisco IOS Release 12.0(5)W5(13b) and later releases.

CSCdp85211

Symptom: ATM signaling would not generate the connect ACK message and would result in conformance test failure.

Workaround: None.

CSCdp84968

Symptom: Under some very heavy stressful conditions with IP multicast, when the mcast fan-out expansion fails, the VCs do not release correctly.

Workaround: Stop the traffic and enter the clear ip mroute* command.

CSCdp84086

Symptom: The primary route processor might loop when a redundancy prepare-for-cpu-removal command is entered.

Workaround: None.

CSCdp83445

Symptom: Synchronous Digital Hierarchy (SDH) and other standard compliancy is not supported on the OC-48c. Also, LEDs and SONET/SDH alarm signals might not generate properly on the OC-48c. When using the show controller command on the OC-48c, counters might duplicate.

Workaround: None.

CSCdp82442

Symptom: Added code to display the SR3 and SR5 registers. No impact to functionality.

Workaround: The show controller counters command is enhanced in Cisco IOS Release 12.0(5)W5(13b) and later releases.

CSCdp81517

Symptom: If you are using IPX EIGRP, you might experience an inconsistency in SAP updates on a remote router if the serial interface is brought down for a brief time and then brought up.

Workaround: Enter the clear ip eigrp neighbors EXEC command or enter the no ipx linkup-request sap command for the serial interfaces.

CSCdp81493

Symptom: When unicast and multicast traffic is present on Fast Ethernet ports, the primary route processor might loop when a redundancy prepare-for-cpu-removal command is entered.

Workaround: None.

CSCdp81136

Symptom: The show atm status command might show the status of a previously looped back interface as up when it should be showing the status as up only after the line loopback is removed from the interface.

Workaround: None.

CSCdp80826

Symptom: Loopback cells might not pass across the 25-Mbps ATM port adapter modules.

Workaround: Configure the no atm oam intercept end-to-end command from global configuration mode.

CSCdp80179

Symptom: When IPX packets are sent to the system, and the system does cross encapsulation for IPX packets, it might lead to a stuck port situation if the IPX protocol length is wrong (or corrupt).

Workaround: Remove the interface module and reinstall it.

CSCdp79042

Symptom: A switch router with the Per-Class Queueing Feature Card (PCQ FC) might not count received cells per VC on transit VCs.

Workaround: None.

CSCdp77640

Symptom: IPX node address of BVI is sometimes made invalid after a long period of time.

Workaround: Enter the shutdown and no shutdown commands on the BVI interface to recover. The node entry is programmed properly back in the table.

CSCdp77324

Symptom: Online insertion and removal of the route processor, even after entering the prepare-for-cpu-removal command, sometimes hangs the system.

Workaround: Power cycle the system.

CSCdp77105

Symptom: Term length does not work for the show functional-image-info command.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp76943

Symptom: The display from a show switch fabric command scrolls without stopping when the screen fills. The output just continues to the end of the display.

Workaround: None.

CSCdp75180

Symptom: The switch router does not correctly handle extended QoS and end-to-end transit delay IEs. This occurs primarily when interoperating with third-party vendor equipment.

Workaround: None.

CSCdp74941

Symptom: When reprogramming a switch processor FPGA after a route processor switchover, the warning and the confirm prompts might not appear.

Workaround: None.

CSCdp74821

Symptom: The following error message might appear during switch processor FPGA reprogramming:

Cat85xx series supports a maximum bridge table aging timer of 600 secs

Workaround: None.

CSCdp72650

Symptom: Multiple tags for the default route might occur with VC merge.

Workaround: Do not use the tag-switching ip default-route command to assign tags to the default route.

CSCdp72498

Symptom: The input queue count on a BVI interface configured on the switch router might become larger than queue depth. This will block traffic from the same bridge group.

Workaround: Increase the hold queue on the BVI interface, depending on the rate at which the input queue fills up, or redesign the network to remove BVI.

CSCdp70903

Symptom: The switch router might crash after displaying the following message:

ipc_ok2send: Not enough room on 0, 280

Workaround: None.

CSCdp70392

Symptom: When a port is stuck there is no debugging aid.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp70087

Symptom: When the system receives a lot of bad IPX packets, it sometimes produces a spurious memory access error. This does not impact functionality.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp69276

Symptom: With the eight-port Gigabit Ethernet interface module, spurious memory access occurs when booting the system with the latest image and copying the software configuration from a TFTP server.

Workaround: None.

CSCdp67518

Symptom: If interface snooping is configured, saved to NVRAM, and reloaded, the snooping VC might come up in a NO HW RES state.

Workaround: Use the shutdown command to bring down the interface.

CSCdp66953

Symptom: With the 8-port Gigabit Ethernet interface module, ping fails when changing the VLAN ID of a BVI interface.

Workaround: Take the subinterface out of the bridge group before changing the encapsulation. Then change the encapsulation and add the subinterface back to the bridge group.

CSCdp66611

Symptom: A VP associated code point is not supported between a Catalyst 8540 and a V switch on UNI 4.0/IISP interfaces.

Workaround: Use the atm signalling vpci command to configure the value of the VPCI that is carried in the signalling messages in the VP tunnel.

CSCdp66533

Symptom: The connected route associated with an Ethernet interface might not be in the routing table.

Workaround: Clear the routing entry or the Ethernet interface.

CSCdp66044

Symptom: When a port is stuck there is no debugging aid.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp66533

Symptom: Connected route associated with Ethernet interface might be intermittently missing from routing table.

Workaround: Clear the routing entry or the Ethernet interface.

CSCdp65345

Symptom: The image crashes when redundancy for the route processors is enabled.

Workaround: None.

CSCdp64865

Symptom: When the ipx down command is entered on an interface, the routing flag for IPX remains on.

Workaround: None.

CSCdp63969

Symptom: The switch can be configured to get its network clock from a constant bit rate (CBR) port without any clock being supplied to the port.

Workaround: None.

CSCdp63799

Symptom: New SVC or soft PVC calls from a Catalyst 8540 to a Fore ATM switch across a PNNI interface fail to connect. Connections initiated from the Fore switch do not fail.

Workaround: None.

CSCdp61799

Symptom: Under the heavy stress of a large volume of multicast traffic (6K [S,G] 1MB) the switch router crashes after failing to queue IPC messages.

Workaround: None.

CSCdp61681

Symptom: Counter values from the show controllers command are not descriptive enough for troubleshooting purposes. Each counter should have a label indicating the purpose of the counter.

Workaround: The output has been improved in Cisco IOS Release 12.0(5)W5(13b) and later releases.

CSCdp60263

Symptom: A mechanism is needed to troubleshoot and recover from port stuck failures.

Workaround: To recover from a port stuck failure, perform the following tasks:

Detect port stuck failure.

Isolate the cell stuck failure.

If it is only a port stuck failure, isolate the port from the other functional ports, and inform Cisco that the line is down/down.

Depending on the configuration option for reset of the stuck port, the following action will be taken:

Default behavior

If the switch router is not configured to reset the port upon detecting a port stuck failure the port will be isolated, thus preserving the integrity of the switch router.

Nondefault behavior

If the switch router is configured to reset the port upon detection of a stuck port failure, the switch router will isolate the port from the rest of the functioning ports, and reset the port. This might affect up to three other ports in the case of Fast Ethernet 10/100 modules.


Note If you configure the switch router as described in the nondefault behavior after a port stuck failure is detected, the switch router will not reset the Ethernet ports. The Ethernet interface must be configured to reset before the port stuck failure occurs. Also, the default behavior is to not reset the port if a port stuck failure is detected. If the Ethernet interface is not configured to reset when a port stuck failure is detected, schedule the switch router for downtime to remove and reinsert the module.


Use the following interface configuration commands to troubleshoot port stuck failures:

Command
Purpose

epc port-reload

Enables automatic resetting and reloading of the Ethernet interface module microcode after detecting a port stuck failure.

epc portstuck-wait seconds

Specifies the delay before signalling a port stuck failure (from the time the failure is detected). The default is 180 seconds. The range for seconds is 0 to 1200. A value of 0 seconds causes a port stuck failure to not be detected.



Caution Due to the nature of microcode architecture, do not configure low values for the wait time in the epc portstuck-wait command. The default value of 180 seconds has been carefully chosen, allowing for the hello intervals of protocols such as HSRP, EIGRP, OSPF. Configuring a low value might lead to incorrectly detecting temporary port stuck failures as real port stuck failures and will likely cause temporary connectivity loss. It is highly recommended to keep this value at least at 60 seconds. Lower values are provided to allow for some specific network designs when you can absolutely rule out temporary port stuck failure scenarios, and also as a debugging aid. For most networks, 180 seconds should work very well.

CSCdp59602

Symptom: On the Catalyst 8540, routing with BVI does not work on the 8-port Gigabit Ethernet subinterfaces with the following configuration:

Switch(config)# interface GigabitEthernet card/subcard/port.subinterface
Switch(config-if)# encapsulation dot1Q 12 native

Workaround: Reconfigure the dot1Q VLAN as non-native.

CSCdp59046

Symptom: Variable bit rate (VBR) might allow sustainable cell rate (SCR) oversubscription.

Workaround: None.

CSCdp57307

Symptom: A Catalyst 8540 might treat the link between the physical interface and the port channel interface as a multidrop link when the MAC address of the members of a port channel differs from the MAC address of the port channel itself.

Workaround: Delete the members of the port channel and then add them back in.

CSCdp57023

Symptom: The administrative status might be shown as up even when the controller is administratively down.

Workaround: None.

CSCdp55616

Symptom: Issue the shutdown and no shutdown commands for the new setting to take effect when you change the port speed from 10 to 100 seconds on a Catalyst 8540 CSR running 12.0(5)W5(13).

Workaround: None.

CSCdp54731

Symptom: FastEthernet interfaces that are in shutdown mode have packet output and bytes incrementing in the show interface command.

Workaround: Issue the clear counters command.

CSCdp54685

Symptom: Permanent virtual circuit (PVC) creation might fail if the virtual channel identifier (VCI) is greater than 24 bits. On a reload this error might happen when the VCI is greater than 12 bits.

Workaround: None.

CSCdp54010

Symptom: Some of the interface counters display a lower value for packet counters. Increasing the frequency of poll for statistics resolves the problem. This is needed only in two-port Gigabit Ethernet interface modules because of separate channels. This does not affect functionality.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or later.

CSCdp53792

Symptom: Cisco IOS Release 12.0(5)W5(13) and later releases boot only on route processors with hardware SAR.

Workaround: If you have a route processor with software SAR (that is, below version 5.4), you must upgrade your route processor to one with hardware SAR (version 5.6 or later). For route processor related issues, see the field notice at http://cco/warp/customer/770/fn5889_06291999.html.

CSCdp53383

Symptom: A MAC address that is learned as a REMOTE entry in the port channel members gets learned as a LOCAL entry after a host move.

Workaround: Issue the clear bridge bridge-id command.

CSCdp53262

Symptom: A host move under high traffic conditions can result in a missing MAC entry from the IOS bridging table. When routing over BVI, this might cause loss of connectivity.

Workaround: Issue the clear bridge command.

CSCdp52147

Symptom: When configuring a port channel, set the hold-queue size of the port channel to 300 and save it to NVRAM. On physical interfaces and port channels, the default hold-queue size is 75. The port channel hold-queue size should be 300. If the queue size of the port channel is not reset, there might be occasional packet drops bound to the route processor.

Workaround: None.

CSCdp52120

INTERNAL ASSERT: lss_ipm_chk_shr_vc() Assertion failure

Symptom: These messages occur when there is IP multicast traffic and the user disables PIM on a physical interface and moves this physical interface to be a member of a port channel that is PIM enabled.

Workaround: Stop the IP multicast traffic, issue the clear ip mroute * command, and make the configuration change. If the assert messages occur, clear ip mroute * should fix the problem.

CSCdp51900

Symptom: When a member is removed from a bridge group which has HSRP over BVI configured and the router is an active router, active router MAC 0000.0c07.ac00 might not be removed from the interface.

Workaround: Issue the shutdown and no shutdown commands.

CSCdp53470

Symptom: A Simple Network Management Protocol (SNMP) walk of the ATM virtual channel cross connect table (CCT) might incorrectly show the following for a manually created cross connect:

atm MIb.atmMIBObjects.atmVcCrossConnectTable.atmVcCrossConnectEntry. atmVcCrossConnectAdminStatus.4680082.16.41.32.15.9.32 = up(1)

Workaround: None.

CSCdp50675

Symptom: On a 8540 MSR running 12.0(4a)W5(11a) that the following entries may appear in the log:

*Dec 10 04:54:03.806: %ALIGN-3-SPURIOUS: Spurious memory access made at 0x60448AF0 reading 0x0
*Dec 10 04:54:03.806: %ALIGN-3-TRACE: -Traceback= 60448AF0 60448958 604468EC 601451D0 60148840 60149004 60143FB8 60153718

The entries may appear when doing a SNMP get command. This may sometimes cause the active RP to crash and failover to the Standby RP (if available).

Workaround: Upgrade to Cisco IOS release 12.0(10)W5(18c) or later.

CSCdp50167

Symptom: Inverse multiplexing over ATM (IMA) groups might intermittently fail to come up, especially after reload and on E1 links.

Workaround: Enter the following command on the IMA interfaces:

(config-if)# fwmon "altrap 00 ff 00 ff 00 ff"

If the group remains down even after issuing this command, this indicates a persisting alarm on the line.

CSCdp49816

Symptom: This problem is seen very infrequently when a large configuration is copied to the running configuration under heavy traffic loads.

Workaround: Issue the clear bridge command.

CSCdp49399

Symptom: For 10/100 Fast Ethernet interface modules, the internal chip set is designed to give higher priority to ingress tasks than egress tasks because of limited buffer availability on the ingress side. This design leads to a situation of egress starvation under heavy input traffic conditions when continuously scheduled ingress tasks cannot meet the 84-cycles budget requirement under "Auto L2-learning" conditions.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp49173

Symptom: When hundreds of TVCs in bidirectional mode are repeatedly configured and unconfigured on a switch router, VC resources might become exhausted.

Workaround: None.

CSCdp48943

Symptom: If any bridge-group members are 802.1q subinterfaces on an eight-port Gigabit Ethernet interface module, then protocol specific IRB configuration will not work over these ports because of local-switching ASIC (K1) chip limitations.

Workaround: None.

CSCdp48903

Symptom: The packet statistics displayed by the show epc ipmcast command sometimes report an incorrect value. This does not impact any functionality.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp43332

Symptom: PNNI/ILMI VCs are sending out CLP=1 traffic.

Workaround: None.

CSCdp43220

Symptom: When configuring the Simple Network Management Protocol (SNMP) trap receiver with the snmp-server host command, the following error message might appear on the console of the switch:

%Bad OID Failed to create host entry.

Workaround: This error message occurs only when SNMP is initially configured on the switch and it is the first time that the snmp-server host command is entered. If the command is entered again the error message does not appear.

CSCdp43184

Symptom: PVC and VC status might not be updated in the Frame Relay end of a connection.

Workaround: None.

CSCdp42136

Symptom: When the tag switching is configured while the switch is rebooting, the following warning message displays:

ATMCORE-3-INTERNAL_ERROR:connUpdateFreeVxiMap:invalid tvc

Workaround: None.

CSCdp40308

Symptom: The facility alarm issues a warning when the secondary route processor is brought down, but the warning goes away if the secondary route processor is initialized at ROMMON without booting.

Workaround: None.

CSCdp39497

Symptom: After booting the image, the switch router might display the following error messages and continue looping:

00:04:06: %SYS-3-LOGGER_FLUSHED: System was paused for 00:00:34 to ensure console debugging output.

00:04:07: ipc_ok2send: Not enough room on 0, 84

. . .

Workaround: None.

CSCdp39811

Symptom: The root cause of this is that the HSRP specific structures are not properly updated when an interface goes down or when a card is removed.

Workaround: Remove HSRP from the configuration before removing the card.

CSCdp36779

Symptom: When E1 Frame Relay ports are coming online the following message might be displayed:

pam_interrupt: unknown pam in slot <slot_number>

This message is harmless and does not affect the functioning of the switch router.

Workaround: None.

CSCdp34890

Symptom: When the color of an encapsulation is changed on a subinterface, the subinterface does not transition through the spanning tree states. In some situations this might result in spanning tree loops.

Workaround: To prevent looping when changing the subinterface color, delete the subinterface and recreate it with the new encapsulation color.

CSCdp34129

Symptom: When several IP/IPX ACLs are configured on Ethernet interfaces, a switchover might cause the primary CPU to crash.

Workaround: None.

CSCdp34084

Symptoms: The following error messages might appear on the Gigabit Ethernet interface module with the ACL daughter card during a route processor switchover.

NO ACL Card Detected on the PAM in Slot[0]
FATAL ERROR: ACL-FPGA reset failed

Workaround: OIR the interface module.

CSCdp33630

Symptom: On Fast Ethernet ports, untagged packets coming in on the 802.1q native VLAN are not processed by the microcode. Instead, they are transmitted to the route processor and processed. This means that high route processor utilization will be seen if untagged packets are received at a high rate on the native VLAN subinterfaces.

Generally, only management data, transmitted at a very low rate, would be seen on the native VLAN, since it is mainly used for network management purposes.

Workaround: None.

CSCdp33023

Symptom: A Catalyst 8540 might have problems with IPX routing using ATM router module ports. Once the LE-ARP entry times out, IPX packets are sent over the BUS. Because the route processor is not aware of the IPX packets anymore, it does not trigger the LE-ARP request and the switch router continues to forward the IPX traffic for the given destination over the BUS. This problem negatively impacts IPX performance. IP performance is not affected.

Workaround: Set the atm idle-timeout command to 0 on all the devices in the affected ELAN before the traffic is started, or move the LES/BUS to a Catalyst 5000 ATM LANE module.

CSCdp32289

Symptom: HSRP interface tracking may incorrectly determine that a down interface is up when the software reloads.

Workaround: Enter the shutdown/no shutdown commands on the interface.

CSCdp31368

Symptom: The interface command arp timeout 300 disappears from the running configuration after a reboot.

Workaround: None.

CSCdp31976

Symptom: If a switch processor switchover is initiated from a console port, some commands might still be able to be entered from a connection through a telnet or a vty session.

Workaround: Wait until the switchover is complete before issuing any commands from a vty port.

CSCdp31368

Symptom: The arp timeout interface command disappears from the running configuration after a reboot.

Workaround: Upgrade to Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdp30288

Symptom: The following message is sometimes seen:

Received malformed TLV

Workaround: None; this message is harmless.

CSCdp29985

Symptom: In large bridge group and bridge group member configurations exceeding supported limits, high route processor utilization from the Tbridge Monitor process might occur. System resumes normally.

Workaround: None.

CSCdp29577

Symptom: When multiple 802.1q subinterfaces are configured over interfaces belonging to the same slot of an 8-port Gigabit Ethernet interface module, the traffic will be locally switched (broadcasts, flooding, etc.) among those interfaces, and the front-panel subinterfaces are represented by a single subinterface in the back end. Therefore, it does not consistently represent the proper configuration of front-panel subinterfaces. Because of this, the front-panel port configuration might not always work, depending on the deployment scenario.

Workaround: Configure different encapsulations among the different subinterfaces in the same slot. This makes the Ethernet interfaces in the back end perform bridging and routing.

The above workaround applies only if the subinterfaces are used to perform different switching functions. Multiple subinterfaces with the same encapsulation in the same bridge group might be used to provide local switching capability for trunk ports and possibly routing over BVI.

CSCdp29185

Symptom: On reload after configuring a permanent virtual circuit (PVC), the PVC might be in the down state.

Workaround: Delete and re-install the PVC.

CSCdp28511

%SYS-3-INTPRINT: Illegal printing attempt from interrupt level. -Process= "OIR Handler", ipl= 2, pid= 10 -Traceback= 600386C0 60038134 602C08BC 602BAEB4 602BA000 600B07F4 603BC180 603BBE80 602C9B88 602C9CB8 60351A74 600976F4 600976E0

Symptom: The above messages sometimes appear upon online insertion and removal (OIR) of the route processor or switch processors and also of the 2-port Gigabit Ethernet or 10/100 Fast Ethernet interface modules. This message is harmless and the system should continue to function normally after the message.

Workaround: None.

CSCdp27782

Symptom: The redundancy prepare-for-cpu-removal command initiates a route processor switchover through a software forced crash. The forced crash causes the message buffer to flush and display to the console before initiating the switchover.

Workaround: None.

CSCdp27744

Symptom: It can take up to 3 minutes to sync up the running configuration to the secondary route processor upon inserting the secondary route processor. This is not a problem. The task is run as a background task and hence runs as a low priority task.

Workaround: None.

CSCdp27207

Symptom: The switch processor switchover might generate a route processor HOG message in the Exec process. Console input is blocked until the switchover is complete. The system resumes normally.

Workaround: None.

CSCdp27071

Symptom: In bridge group and bridge group member configurations exceeding supported limits, route processor HOGs from the Net Background process might appear. System resumes normally.

Workaround: None.

CSCdp27067

Symptom: In bridge group and bridge group member configurations exceeding supported limits, route processor HOG messages from the EPAM Card Manager process might appear. System resumes normally.

Workaround: None.

CSCdp27058

Symptom: Route processor redundancy requires a software interface descriptor block for the secondary route processor. If you use up all the interface descriptor blocks through subinterface creation before booting the secondary route processor, interface descriptor block creation failure occurs. Boot the secondary route processor before attempting to configure the maximum number of interface descriptor blocks.

Workaround: None.

CSCdp25363

Symptom: If a switch processor switchover occurs before K1 boots up, the switch router might hang or crash.

Workaround: None.

CSCdp24812

Symptom: After hot-swapping a fast Ethernet interface module, OSPF interfaces are not recognized.

Workaround: Configure a loopback interface before enabling OSPF, so that the IP address of the loopback will be selected as the OSPF router ID. This is the recommended design for OSPF configuration. To minimize the convergence time, use a software interface (which never goes down unless administratively shut down) as the router ID. This will also prevent OSPF restarts upon interface toggling.

CSCdp23213

Symptom: After a switch processor switchover, the input and output packet counters have invalid values.

Workaround: None.

CSCdp23208

Symptom: Ethernet interface modules reset during reinitialization after a switch processor switchover.

On a switch processor switchover, Ethernet interface modules behave as if a system reload occurred, and take the same amount of time to reinitialize as they do for a reload. Before the interface modules come up, and a switchover occurs, timeout messages are entered. This happens because the Ethernet ports are initialized through IPC, and halfway through the process the Ethernet interface modules are reset again by the switchover.

Workaround: None.

CSCdp22877

Symptom: With the following configuration:

line con 0
exec-timeout 0 0
privilege level 15 <<<<<<<<<<<<<<<<<<
length 48
transport input none

The switch will bootup in enable mode.

If a CPU switch-over occurs, the switch will not preserve this configuration and will boot up in user mode.

Workaround: We recommend that the user enter enable password to enter enable mode after a CPU switch over.

CSCdp22692

Symptom: After hot-swapping a fast Ethernet interface module, OSPF routes are not propagated properly.

Workaround: Issue the shutdown and no shutdown commands on the appropriate interface.

CSCdp22516

Symptom: Do not hot swap an active switch processor (SP) module before putting it in standby mode.

If an SP module is currently active while the switch router is running IOS, and the module is removed from the chassis before making it a standby module, the connections might hang. This stops switch traffic after an SP switchover.

Workaround: Before removing an active SP module, make it the standby.

First determine whether the SP module to be removed is currently active using either of the following methods:

Use the show preferred-switch-card-slots command.

Look at the LEDs on the SP modules.

If the SP module is active, the active LED on the module is green.
If the SP module is standby, the standby LED on the module is green.

If the SP module is currently the standby, remove it without issuing any commands.

If the SP module is currently active, use the following EXEC command to designate the other two SP modules as the active switch processor modules:

redundancy prefered-switch-card-slots slot#1 slot#2

The range of the slot value is 5 through 7. This prepares the SP module to be removed as the standby module.

Once the prompt returns, ensure that the SP module is the standby by issuing the following command:

show preferred-switch-card-slots

The SP module should no longer be active, and can be safely removed.

The following example shows how to prepare the switch router to safely remove an active SP module from slot 5:

Switch# show preferred-switch-card-slots The currently preferred switch card slots are slot:5 and slot:7 The currently active switch card slots are slot:5 and slot:7
Switch# redundancy prefered-switch-card-slots 6 7
Switch# show preferred-switch-card-slots
The currently preferred switch card slots are slot:6 and slot:7 The currently active switch card slots are slot:6 and slot:7

CSCdp22057

Symptom: OC-48c SONET is supported but SDH is not.

Workaround: None.

CSCdp21879

Symptom: If an OC-48c interface module is removed and reinserted on an active switch router when NCPD is enabled, and the clock source is set to the OC-48c interface, the ILMI state remains in waiting/restarting on the OC-48c interface.

Workaround: After the OC-48c interface module is reinserted, enter a shutdown command, followed by a no shutdown command on the affected OC-48c interface.

CSCdp21758

Symptom: CBR interfaces might incorrectly come up when configured as structured services, even though no cables are plugged into the ports. This problem might also occur when removing the configuration of the structured services.

Workaround: Remove and reinsert the CES port adapter.

CSCdp21692

Symptom: When the secondary route processor is brought to ROMMON and initialized in the rommon, the redundancy alarm is cleared in the primary route processor even though the secondary route processor is still down.

Workaround: None.

CSCdp20865

Symptom: Entering shutdown/no shutdown commands on an ATM router module interface, especially when it has several LANE clients configured, can cause the switch router to issue messages similar to the following:

%LANE-3-LANE_ERROR: lecs finder: ILMI hung on interface ATM1/0/0

This message indicates that an internal timeout occurred. The interface recovers and normal operations are not affected.

Workaround: None.

CSCdp20845

Symptom: Under heavy stress conditions with multicast PIM-DM, there can be a situation in which VC allocation failed messages appear. This is a high stress scenario, and it happens when all the VC resources are not freed properly.

Workaround: Stop the traffic for a short time (a few minutes), enter the clear ip mroute * command, and then restart the traffic. This caveat has been resolved by ensuring that the VC resources are cleaned up properly in Cisco IOS Release 12.0(5)W5(13b) and later releases.

CSCdp20608

Symptom: The show interfaces atm-sec0 command always displays zero counter values.

Workaround: None.

CSCdp20230

Symptom: The switch router might crash when logging messages to a buffer when the switch router is very active.

Workaround: None.

CSCdp19523

Symptom: If an IPX router goes down in a multiple-path topology, the Catalyst 8540 layer might get out of synchronization with the Layer 3 IPX routing table. A lower layer forwarding and switching anomaly might occur if the router first receives a "down" notification for a particular network from the same host that originally notified the router about that network, and then, shortly afterward, the router receives a good route to the network from another host.

Workaround: None.

CSCdp19342

Symptom: The switch router sends PIM v2 register messages when PIM v1 is configured.

Workaround: None.

CSCdp19060

Symptom: The secondary route processor incorrectly displays out-of-sequence messages even though the packets are resent and the sequence is recovered.

Workaround: None.

CSCdp15945

Symptom: If a Fast Ethernet interface module is installed on an active switch router, cells become stuck in the switch fabric when a route processor module is inserted into the chassis.

Workaround: Upgrade to Fast Ethernet FPGA 3.3 or later.

CSCdp14997

Symptom: Flash PC cards cannot be formatted on the secondary route processor.

Workaround: Format the Flash PC card on the primary route processor then move it to the secondary route processor.

CSCdp14860

Symptom: If an 8-port Gigabit Ethernet interface module is installed on the switch router, switch processor switchover is temporarily unsupported. After issuing a redundancy prefered-switch-card-slots command, the switch router displays the following message:

There is 8 Port Gigabit Ethernet PAM in the Chassis, SP switch over is temporary unsupported

Workaround: None.

CSCdp14547

Symptom: A Gigabit Ethernet interface indicates it is in the up state, even though there is no longer connectivity through this interface. Pinging a device through the Catalyst 8540 MSR times out. Pinging a device from the Catalyst 8540 MSR is successful.

The sh epc if-entry int gi 0/0/0 gi 3/0/1 command displays the following message:

Status Down Broute VC - 0

The shutdown/no shutdown command sequence restores the connectivity.

Workaround: None.

CSCdp14547

Symptom: A Gigabit Ethernet interface displays its status as up, however, there is no connectivity through the interface. Pinging a device through the Catalyst 8540 CSR times out but pinging a device from the Catalyst 8540 CSR is successful.

Workaround: Issue the shutdown and no shutdown commands on the appropriate interface to restore connectivity.

CSCdp14175

Symptom: Ports on an eight-port Gigabit Ethernet interface module cannot be snooped or used to snoop other interfaces.

Workaround: Use a Gigabit Ethernet port from a two-port Gigabit Ethernet interface module to snoop.

CSCdp14509

Symptom: The switch router might crash with a bus error. The interfaces were not restored after the crash.

Workaround: None.

CSCdp14004

Symptom: In rare instances, a Catalyst 8510 CSR takes a software forced crash at a program counter value of 0x6004A4D64 when running Cisco IOS Release 12.0(1a)W5(6f). Because the conditions which trigger this crash are not currently known, it is strongly advised that the router be configured to write a core dump if such an instance happens.

Workaround: None.

CSCdp13836

Symptom: Even though the route processor capabilities do not match, the switch router still reports full redundancy when it boots up.

When the secondary route processor resources, such as the amount of DRAM, are equal to or greater than the primary route processor resources, the switch router is fully redundant. However, after a route processor switchover, if the new primary route processor resources are more than those of the new secondary route processor, a fully redundant switch router becomes conditionally redundant and the new primary route processor console displays a message such as the following:

00:03:14: %COUGAR_EHSA-4-FLASH_MISMATCH: Mismatch in BOOTFLASH SIMM size between Primary and Secondary ACPMs
BOOTFLAH SIMM Size - Primary = 16 MB, Secondary = 8 MB
Because of the BOOTFLASH size mismatch, the files that fits in the
Primary ACPM's BOOTFLASH may not fit in the Secondary's BOOTFLASH, if and
when a switchover occurs. This may cause loss of information. The system
is now running CONDITIONALLY REDUNDANT - subject to the above mentioned
mentioned restriction

Workaround: Ensure that both route processors on the switch router have the same resources.

CSCdp11944

Symptom: When copying a file to a Flash PC card on a secondary route processor, the switch router might return control to the user before the copy process is complete. If a reload is done before the image is completely copied, the file might be lost.

Workaround: Enter the dir sec-slotn: command to verify that the image is completely copied before reloading the switch router.

CSCdp10310

Symptom: IP multicast counters (S,G) might not be accurate.

The microcode maintains 16-bit packet counters for each (S,G) entry, which are polled every 10 seconds. If the input rate for the (S,G) entry is higher than 6.4K packets/second for a 10-second duration, the counters might overrun.

Workaround: None.

CSCdp08794

Symptom: On an OC-12 interface, the show controllers command might incorrectly show very large numbers of tx and rx counters.

Workaround: None.

CSCdp08255

Symptom: The show running-config command display contains a reference to the aux 0 port, which is not supported.

Workaround: None.

CSCdp08242

Symptom: The undebug all command does not disable the debug redundancy all command.

Workaround: Use the no debug all command to disable all debugging activity.

CSCdp07226

Symptom: If the configuration register value is set to 0x2102 while autobooting, the system might experience a TLB (translational bridging) exception if the system boot image is not specified using the boot system command. The system continues to boot without problems, despite this exception.

Workaround: When the configuration register is set to 0x2102, specify the system boot image to be autobooted using the boot system command. If the system boot image is specified using the boot system tftp command, also specify the bootloader image using the boot bootldr command. After executing these commands, save the configuration in the NVRAM, using the copy running-config startup-config command.

CSCdp06298

Symptom: All Software Upgrade (system IOS, ATM, FDDI) is broken on Cluster Manager and VSM if the cluster member's management VLAN has no IP address.

Workaround: None.

CSCdp05103

Symptom: When attempting to reprogram the ROMMON, the switch router sometimes hangs after displaying the following message:

Resetting in 3 seconds

Workaround: Remove and reinsert the route processor module or power cycle the switch router.

CSCdp04109

Symptom: The debug ncdp packets, debug ncdp errors, and debug ncdp events commands do not display any information when accessing the switch router through the Ethernet port.

Workaround: Access the switch router using the console port.

CSCdp03740

Symptom: If ILMI is configured on the terminating interface of a soft VC, ILMI must be in the UpAndNormal state for this soft-VC to come up.

Workaround: Upgrade to the Cisco IOS release 12.0(10)W5(18c).

CSCdp03092

Symptom: The Catalyst 8540 might display a CRC error when it obtains the clock over an OC-3c link from a LightStream 1010 ATM switch and then uses or redistributes the clock over an OC-12c link.

Workaround: Use the internal clock or bring the clock source directly to the Catalyst 8540.

CSCdp01936

Symptom: PVCs exiting the switch router over a hierarchical VP tunnel are not preserved when the route processor switches over.

The switch router stops switching traffic over such PVCs upon and after the route processor switchover. The hierarchical VP tunnel remains active, however, and after the route processor switchover the VCs defined over the hierarchical VP tunnel (both PVCs and SVCs) function as expected.

Workaround: None.

CSCdp01016

Symptom: If no ACL module is present in a slot, the following message appears in the console log on a SP switchover:

No ACL card in slot

This is an informational message only and has no effect on switch router function.

Workaround: None.

CSCdp07758

Fast Ethernet port identifier truncated in the show atm status command.

Symptom: The show atm status command is not supported.

Workaround: The command is supported in Cisco IOS Release 12.0(5)W5(13b) or a later release.

CSCdm95298

Symptom: Bridging on a subinterface is only supported in conjunction with the IEEE Spanning Tree.

Workaround: None.

CSCdm94019

Symptom: Under certain circumstances, the Catalyst 8540 might display inaccurate traffic statistics on NNI or UNI interfaces.

Workaround: None.

CSCdm92990

Symptom: Despite having enough bandwidth, resource management might reject some soft PVCs.

Workaround: None.

CSCdm92257

Symptom: 8-port Gigabit Ethernet interfaces cannot support bridging when the bridge group runs DECNET Spanning Tree.

Workaround: None.

CSCdm92183

Symptom: After shutting down an ATM router module interface which is a member of a port channel, the interface entry is not removed from the port channel. Since removing a member interface from a port channel does not put the port channel into blocking mode, no loss of connectivity should result.

Workaround: None.

CSCdm91571

Symptom: When using the Catalyst 8540 usage parameter control (UPC) tag functions (change the CLP=0 to CLP=1), the following ports might not work: For 16-port OC-3c and 4-port OC-12c interface modules, interfaces ATM 0/0/0, ATM 0/0/2, ATM 2/0/0, ATM 2/0/2, ATM 9/0/0, ATM 9/0/2, ATM 11/0/0, and ATM 11/0/2 might fail UPC tag mode.


Note All other interfaces should work.


Workaround: Upgrade the switch processor FPGA image to Version 1.5 (fi-c8540-msp.A.1-5) or later.

CSCdm91060

Symptom: The ILMI keepalive feature resets the interface on the second retry following a link failure. This behavior might occur despite having configured the system to allow up to five retries.

Workaround: None.

CSCdm91042

Symptom: On a system configured with either both power supplies or only power supply 1, issuing the show hardware, show hardware detail, or show tech-support commands might cause the memory corruption. If this memory corruption occurs and the show subsystem command is entered, the Catalyst 8540 might fail unexpectedly.

Workaround: If the system is configured with two power supplies, remove power supply 1 before issuing any of the commands listed in the Symptom section. If the system is configured with one power supply, make sure that you use power supply 0.

CSCdm90640

Symptom: Alignment correction made while running IPX routing and data packets over dot1q over fec.

Workaround: None.

CSCdm90166

Symptom: If the switch router is booted with cleared NVRAM, because the switch router is new, or after a write erase command, and the automatic configuration is skipped, the following messages are displayed:

%Error opening tftp://255.255.255.255/network-confg (Not enough space)
%Error opening tftp://255.255.255.255/cisconet.cfg (Not enough space)
%Error opening tftp://255.255.255.255/switch-confg (Not enough space)
%Error opening tftp://255.255.255.255/ciscortr.cfg (Not enough space)

These messages are harmless and can be ignored. The only effect is an increased boot time of approximately 1 minute.

Workaround: Use the automatic configuration feature upon first boot-up or when the switch router is booted after a write erase command.

CSCdm89519

Symptom: The digital cross-connect unit (DCU) might malfunction unexpectedly.

Workaround: None.

CSCdm89205

Symptom: Following a route processor switchover, the switch router might fail to recognize port adapter interfaces associated with a carrier module.

Workaround: Upgrade the carrier module FPGA image to release 1.7 or later.

CSCdm89022

Symptom: With RMON enabled on Fast Ethernet interfaces, SNMP interface counters begin to grow exponentially. Port utilization might be greater than 100% when the actual utilization might be as low as 1%. This happens with either RMON native or RMON promiscuous. While SNMP counters are erratic, the CLI remains accurate.

Workaround: None.

CSCdm88183

Symptom: Following a software reload, the Catalyst 8540 might fail unexpectedly with a write bus error. This failure might occur if the system is configured with one route processor, and the switch processor modules are installed in slots 5 and 6 or in slots 6 and 7.

Workaround: Install the switch processor modules in slots 5 and 7.

CSCdm88103

Symptom: The router fails to see incoming AppleTalk broadcasts when the router, configured for IRB, is routing and bridging IP and just routing AppleTalk.

Workaround: None.

CSCdm87966

Symptom: When powering up and booting the switch router with two route processors, or installing a second route processor in a working switch router, the console port of the secondary route processor might display the following error message:

SECONDARY CPU: *** Failure - Can not sync to other CPUs sync ****
Sys Clock lock and sync failed.

The secondary route processor fails to boot and the switch router is in a non-redundant mode. This problem occurs when the Catalyst 8540 with two route processors and the secondary route processor have an FPGA image version of 4.5 or earlier. To recover, power cycle the switch router or remove and reinsert the secondary route processor.

Workaround: Upgrade the route processor FPGA image to version 4.6 or later.

CSCdm87797

Symptom: An IPX packet containing the wrong length in the IPX header and requiring an encapsulation change causes the ingress port to hang. The switch router must be reloaded.

Workaround: None.

CSCdm87397

Symptom: On the Catalyst 8540 CSR running the W5(11) code or lower, adding logging source-interface and then removing logging source-interface might stop syslogs being sent out on Ethernet 0 (the management port). Syslogs continue to be sent out through the regular interface module ports.

Workaround: Do not configure the source-interface. If you configure the source-interface, do not remove the logging source interface. Rebooting the switch router resolves the state. An error syslog (LINK-3-UPDOWN) also corrects the problem.

CSCdm86667

Symptom: The squeeze command might result in an error in which the squeeze progress is not displayed. For example:

ms04_m84_01#squeeze sec-slot0:
All deleted files will be removed. Continue? [confirm]
Squeeze operation may take a while. Continue? [confirm]
Squeeze of sec-slot0 complete
ms04_m84_01#

Workaround: None.

CSCdm86262

Symptom: The switch router crashes when you enter and exit configuration mode repeatedly and quickly.

Workaround: None.

CSCdm84834

Symptom: AppleTalk routing does not work when two connected ports are part of a bridge-group with AppleTalk addresses on the ports and IP addresses on the BVI.

Workaround: None.

CSCdm84798

Symptom: With IRB configured, bridging loops occur if there is a physical loop for the broadcast domain.

Workaround: None.

CSCdm84365

Symptom: The Hot Standby Router Protocol (HSRP) over a Bridge Group Virtual Interface (BVI) configuration is not supported if the BVI encompasses LANE interfaces. This configuration is valid and functional only if the BVI encompasses Ethernet interfaces.

Workaround: None.

CSCdm83635

Symptom: Appletalk is not supported on 8-port Gigabit Ethernet interface modules.

Workaround: None.

CSCdm82878

Symptom: Following a change to a spanning tree, inconsistencies might occur in the bridge members information stored in the Ethernet module interface and the IOS.

Workaround: Use the clear bridge command to purge the bridging cache.

CSCdm82033

Symptom: After repeatedly entering and exiting global configuration command mode, the system might freeze unexpectedly.

Workaround: None.

CSCdm81581

Symptom: When the system is configured to autoboot, and the redundancy prepare-for-cpu-removal command is entered, the route processor does not stay in ROMMON mode, but proceeds to autoboot again.

Workaround: Upgrade the ROMMON image to release 12.0(4.6)W5(13) or later.

CSCdm77987

Symptom: Attempting to format the Intel 200 Series Flash PC card that is currently shipping with other platforms (such as the Catalyst 6000) might cause the Catalyst 8540 to fail unexpectedly with a bus error. If this failure occurs, the system will not boot up successfully until the Flash PC card is removed from the switch router.

Workaround: Remove the Flash PC card from the switch router.

CSCdm77667

Symptom: IPX ping incorrectly shows success during simultaneous pinging.

Workaround: None.

CSCdm76785

Symptom: When a clear bridge command is issued, MAC addresses specified for the access lists are not reprogrammed in the CAM tables.

Workaround: Issuing a shutdown/no shutdown on the bridge port where the access list is configured reprograms the MAC address in all other bridge group members.

CSCdm75735

Symptom: After an interface timeout is expired, adjacencies for static ARP entries are refreshed every minute, which might cause momentary connectivity loss. This does not apply to dynamically created adjacencies.

Workaround: None

CSCdm74898

Symptom: The Catalyst 8540 sends an invalid PDU when the counters are cleared.

Workaround: None.

CSCdm73823

Symptom: Following the online insertion of an interface module into a router configured with IGMP static group and running multicast traffic, failures occur when downloading to the interface module.

Workaround: Either shut down any interface configured with IGMP static group before inserting or removing interface modules; or do not insert or remove interface modules online when the switch router is configured with IGMP static group.

CSCdk72837

Symptom: Path costs on Gigabit Ethernet interfaces shown by the show span command do not match the expected default value of 100.

Workaround: Set the path costs manually. One option would be to set the path cost for Gigabit EtherChannel (GEC) ports to 1 and set the path cost for the non-GEC ports to 2.

CSCdm71729

Symptom: When large numbers of MAC addresses are learned over a port channel, some addresses do not age out after the aging timer expires.

Workaround: Use the clear bridge bridge-id command to remove learned MAC addresses.

CSCdm69765

Symptom: The interface delay metric is set inappropriately for port channel interfaces where one or more Gigabit Ethernet interfaces or Fast Ethernet interfaces are grouped into a channel. The delay for a single Gigabit Ethernet interface is 10 microseconds. The delay for a port channel consisting of one or more Gigabit Ethernet interfaces is 100 microseconds. The delay for a single Fast Ethernet interface is 100 microseconds. The delay for a port channel made up of one or more Fast Ethernet interfaces is 1000 microseconds.

This incorrect setting has implications for routing protocols that use interface delay as part of the metric, such as IGRP and EIGRP, and might cause the routing protocol to prefer a route through a single interface over a route through a port channel, everything else being equal.

Workaround: Manually configure an appropriate delay on the port channel interface using the delay command.

CSCdm69065

Symptom: The "Uptime" for the secondary route processor from a show redundancy command might display incorrectly. This problem occurs because the "Uptime" rolls over after about four hours.

Workaround: None.

CSCdm68875

Message: Job <job name> ran <time>

Symptom: Job <job name> ran <time> messages appear frequently or at regular intervals.

The job event queue on the 8-port Gigabit Ethernet interface module lets the event manager know, in microseconds, the maximum amount of time a job is expected to run. It also tracks how long each job actually ran. The Job <job name> ran <time> message should alert you that a job ran longer than expected. It is not normal for the message to come often or at a regular interval.

Workaround: None.

CSCdm68761

Symptom: Performing an OIR on the secondary route processor might produce the following error message:

%OC3SUNI: Read diagnostics for ATM1/1/0 failed(1)

Workaround: Reboot the system.

CSCdm68368

Symptom: Routing protocols take more time to converge after reboot on a router with large ACLs configured on many interfaces.

Workaround: None. When you reboot a router, it can take considerable time to populate large ACLs on many interfaces, resulting in a delay in the convergence of some routing protocols.

CSCdm66516

Symptom: Configuring interfaces on line aux 0 might cause the redundancy feature to fail. The primary and secondary route processors will boot, but running the show redundancy command on the primary route processor incorrectly indicates that the secondary route processor is down.

Workaround: Remove all configuration commands from line aux 0 and reboot the switch router.

CSCdm64544

Symptom: When using FTP to transfer a core file to a server, the switch router might not create an exception dump following a system crash.

Workaround: None.

CSCdm64047

Symptom: IPX ACL on a subinterface of a non-trunk main interface does not filter traffic.

Workaround: Configure the ACL on the main interface instead of the subinterface to achieve the same result. Due to space limitations, IPX ACL cannot be applied directly to a subinterface of a non-trunk main interface.

CSCdm63047

Symptom: If an interface in subslot 1 of a carrier module is the present active clock source, and an interface in subslot 2 of the same carrier module is the secondary clock source, the clock source of the secondary might be overridden to loop-timed rather than network-derived.

Workaround: None.

CSCdm62162

Symptom: After replacing an existing configured ACL on an interface with another ACL, routed packets that should be blocked are forwarded for a very short period of time.

Workaround: Within a short period of time, the ACL is reprogrammed and block packets as required. When you remove an ACL and replace it with another ACL, ACLs are temporarily removed from memory, and the ACL flag is turned off. Some packets that should be blocked by the ACL will temporarily be permitted until the ACL flag is turned on again.

CSCdm60645

Symptom: When using Cisco IOS Release 12.0(1), the router crashes with a bus error when an attempt is made to remove the bridge-group command.

Workaround: None.

CSCdm60387

Symptom: On a router with a rev-B1 fast Ethernet interfaces, there is no way to turn off time-stamp refresh during destination address lookup. A source address is learned on a port in the initial spanning tree state. After the port goes into blocking state, a destination address lookup on the received packet keeps the entry alive. This is particularly true where the source and destination address are the same, as in the case of keepalive packets.

Workaround: None. This problem does not occur in routers with fast Ethernet interfaces later than rev-B1.

CSCdm58126

Symptom: After upgrading the ACL FPGA image using the reprogram command, the system warns you that the image is not compatible with the current IOS version, and the ACL card might become unusable unless you update the IOS image.

Workaround: Ignore this warning for the ACL card, and continue the FPGA download. Do not ignore this warning for other controllers.

CSCdm57767

Symptom: When configuring ACL on subinterface 1023 or above, the router returns the following message:

CARD:ERROR: access_list_add;Index allocation failed for lookuptype 2
CARD:ERROR: handle_addition:access_list_add failed:label 1, Fast Ethernet3/0/0.3 LSS_ACL_AP_OUTPUT_ACL

Workaround: Limit the number of subinterfaces configured with ACL to 1000 for the switch router.

CSCdm57720

Symptom: Cannot receive CDP packets on a trunk port connected to a Catalyst 5000 if CDP packets are coming on a VLAN for which a subinterface is not configured.

Workaround: To receive CDP packets, configure a dummy VLAN subinterface on the trunk port connected to the Catalyst 5000.

CSCdm57516

Symptom: Two Catalyst 8540 CSRs with 802.1Q VLAN encapsulation cannot ping each other.

Workaround: To receive ARP packets, use ISL VLAN encapsulation on trunk ports connected to a Catalyst 5000.

CSCdm56393

Symptom: The soft VCL counter incorrectly reaches its maximum value upon link transition, thus keeping soft VCs from connecting to ports which have incorrect soft VCL numbers.

Workaround: Reload the system.

CSCdm55248

Symptom: The status LED on the standby switch processor module remains red after boot up.

Workaround: None.

CSCdm54297

Symptom: When the switch router is booted after a power cycle, the reload reason in the show version command does not indicate that the "System restarted by power-on."

Workaround: Upgrade the ROMMON image to release 12.0(4.6)W5(13) or later.

CSCdm54001

Symptom: After performing an OIR on a carrier module, the corresponding port adapter interface counter values displayed in a show interface command might become unreliable.

Workaround: None.

CSCdm52306

Symptom: When a static route pointing to one interface is changed to point to a different interface, the corresponding adjacency entry is not updated.

Workaround: Use the clear arp command to reprogram the correct adjacencies.

CSCdm51009

Symptom: When a port adapter is removed from the chassis, the entry in ciscoLS1010SubModuleTable is not deleted.

Workaround: None.

CSCdm50065

Symptom: When you insert an 8-port Gigabit Ethernet interface module while IOS is running, you see the following message:

Jul 15 11:33:31.528 pdt: %OIR-6-INSCARD: Card inserted in slot 12, subcard 1, interfaces administratively shutdown
Jul 15 11:33:31.788 pdt: %ATMSIG-3-FAILASSERT: Assertion failed: file "../src-4k/alignment.c," line 897
FALSE
-Traceback= 6046FA4C 60096908 600971D4 600B1F10

The LED on the interface module is orange and none of the interfaces will work. The interface module is nonfunctional.

Workaround: Reload the Cisco IOS software, and the interface module will function. The LED should always be green when the 8-port Gigabit Ethernet interface module is functioning.

CSCdm49429

Symptom: Connections to the ATM router module interfaces cannot pass through shaped VP tunnels.

Workaround: Configure hierarchical VP tunnels for ATM router module interface connections.

CSCdm48886

Symptom: The Catalyst 8540 does not support a PVP tunnel with a VPI value of 0.

The IOS software relates subinterface 0 to the main interface, so interface ATM x/y/z.0 represents the main interface x/y/z. If the user attempts to create a PVP tunnel with a VPI value of 0, the system should return an error on interface ATM x/y/z.0.

Workaround: None.

CSCdm47048

Symptom: An unexpected system failure might occur following a show tech-support command when OC-3c interfaces are present. This might also occur with the show controllers command.

Workaround: None.

CSCdm47012

Symptom: The versions of the Smart Modular and Sharp Flash PC cards used to store diagnostics and IOS software images might report unrecoverable write errors. Affected cards use a Sharp chip set (LH28F016SCT).

Workaround: If you have a Smart Modular Flash PC card, the fix for this problem is available with the Cisco IOS Release 12.0(4a)W5(11a) software. Netboot the image, reformat the Flash PC card and copy the image to it. You can then autoboot from the Flash PC card.


Note For redundant systems, only the primary route processor can be netbooted.


CSCdm46430

Symptom: The Catalyst 8540 does not allow you to configure more than 255 VPs, even though the 12-bit VPI allows a maximum of 4095 VPs.

Workaround: None.

CSCdm45453

Symptom: The ciscoLS1010ChassisInletTempStatus MIB, which is an object added for the Catalyst 6400 platform, does not return a value.

Workaround: This object is not supported by the LightStream 1010 or Catalyst 8500 platforms.

CSCdm44497

Symptom: On a PNNI signalling link, the Promina 4000 NET switch sends a message that prompts the system to send a CALL PROCEEDING message and then a RELEASE message. The UNI 3.0 specification, section 5.4.5.15, defines a cause code 8a as "VPCI/VCI unacceptable." When the call goes out on a UNI 3.1 interface, this cause code should be mapped to VPI/VCI assignment failure. This mapping does not occur for PNNI links.

Workaround: None.

CSCdm44167

Symptom: EIGRP updates are missing for some addresses on ATM router module port subinterfaces.

Workaround: In global configuration mode, enter the no auto-summary command followed by the auto-summary command.

CSCdm44079

Symptom: A problem in the reinitialization logic might cause the system to fail unexpectedly when a switch processor module in slot 5 is the standby and the switch processor module in slot 7 fails.

Workaround: Do not configure the switch processor in slot 5 as the standby.

CSCdm43664

Symptom: When the system is configured to autoboot, and the configuration register is set to 0x2102, the secondary route processor crashes during autoboot.

Workaround: Upgrade the ROMMON image to release 12.0(4.6)W5(13) or later.

CSCdm43436

Symptom: Incorrect MAC address entries in the CAM table might cause HSRP to fail over a BVI interface.

Workaround: None.

CSCdm41015

Symptom: The following messages may appear on the console. They are not reproducible.

15:28:43: %LANE-3-LEC_CONTROL_MSG: Received bad control message on interface ATM11/0/0.14Cant find ARM bound VC, port = 102, vci=0

The message appears on subinterface ATM11/0/0.14 on the ATM router module port.

Workaround: None.

CSCdm40533

Symptom: The device might lose its IP OSPF neighbor information and connections over a BVI interface after a few days of running, requiring a system reboot.

Workaround: None.

CSCdm39686

Symptom: IP prefix entries in the CAM table might point to incorrect adjacency information, causing routing failure.

Workaround: None.

CSCdm36800

Symptom: The CES ABCD bits are not user configurable when a fault occurs.

Workaround: None.

CSCdm36790

Symptom: When forwarding a call setup message from one VP tunnel to another, the Catalyst 8540 might drop certain information elements that are considered mandatory. This problem might cause compatibility problems with third-party equipment.

Workaround: None.

CSCdm36745

Symptom: Configuring a channelized E1 (CE1) Frame Relay 2.048-Mbps ATM port adapter for clear E1 might cause the linecode violation and LES counters to increment continually.

Workaround: None.

CSCdm36648

Symptom: The device might lose IPX connectivity over a BVI interface, requiring the use of the clear ipx route* command to reestablish connectivity.

Workaround: None.

CSCdm35971

Symptom: After executing an IPX ping with a timeout value of zero, subsequent IPX pings on the device will fail.

Workaround: None.

CSCdm34838

Symptom: When an FEC is configured as a part of a bridge group and a topology change occurs, the bridge table might get out of sync with the Layer 2 CAM information.

Workaround: Use the clear bridge command to keep the IOS bridge table and the Layer 2 CAM in sync.

CSCdm34634

Symptom: atmfAtmLayerConfiguredVCCs might not include the soft PVC count.

If a router connects to an ATM interface on a Catalyst 8540 where soft PVCs are configured, the PVC Discovery feature on the router fails to correctly discover all the configured PVCs and soft PVCs from the switch router. This does not happen if only PVCs are configured.

Workaround: None.

CSCdm33903

Symptom: A fully loaded Catalyst 8540 CSR with 2-port Gigabit Ethernet modules boots properly from bootflash and slot, but does not boot from tftp.

Workaround: None.

CSCdm33737

Symptom: Marker cells are not drained after entering the shutdown/no shutdown command on the interfaces.

Under stress conditions, if there are several hierarchical VP tunnels configured and if the tunnel interfaces are transitioned several times, cells might stay in the switch fabric.

This does not occur on interfaces without hierarchical VP tunnels.

Workaround: None.

CSCdm33313

Symptom: If you configure BVI, but do not want to do IP routing at the BVI level, and you have IP addresses for the interfaces in the bridge group, then routing protocols might not work.

Workaround: Remove the interfaces from the bridge group and then add them back into the bridge group.

CSCdm32706

Symptom: When a large number of bridge groups or bridge group members are configured and IRB is enabled on the devices, reloading one of the devices or configurations might lead to high route processor utilization. The side effect of this is temporary spanning-tree loops, leading to AAL5 buffer exhaustion problems.

Workaround: In this case, if IRB is enabled, you might need to increase the number of buffers on the device using the aal5 buffers command.

CSCdm32506

Symptom: After entering the show running-config command several times, the Catalyst 8540 might fail unexpectedly due to a bus error.

Workaround: None.

CSCdm30294

Symptom: The file system fails to add the secondary NVRAM and secondary RCSF on a route processor switchover.

Workaround: None.

CSCdm30269

Symptom: No means to change the default active switch processor modules is available.

Workaround: If a Catalyst 8540 has three switch processor modules, by default the switch processor modules in slots 5 and 7 come up as the active switch processor modules and the switch processor module in slot 6 comes up as the standby. To change this default, use the following privileged EXEC command:

redundancy preferred-switch-card-slot slot#1 slot#2

Two preferred slots must be specified and they must be unique. The range of the slot value is 5 to 7. If one of the preferred slots selected is not a currently active switch processor module, you are asked whether the system should change the active switch processor module to the preferred switch processor module. If such a switchover occurs, all the active connections in the system are reinitialized. If you wish to continue, then the preferred switch processor modules become active and the other switch processor module becomes the standby. This configuration remains in effect until one of the active switch processor modules is removed. The preferred switch processor module configuration is preserved across route processor switchovers. However, the preferred switch processor module setting is lost if the system is power cycled or if both route processors are reloaded to ROM monitor mode.

CSCdm30023

Symptom: Setting the gateway of last resort is delayed on route processor switchover.

The static IP routes take from 1.5 to 2 minutes to take effect on switchover.

Workaround: None.

CSCdm30009

Symptom: The primary route processor should not be hot swapped.

If a route processor that is currently running IOS is removed from the chassis in a skewed manner, such that the left side of the route processor comes out before the right side does, the traffic through the switch router might stop.

Workaround: There are some precautions to take before removing a route processor module controller from a chassis that is powered-up.

If the route processor module is currently in ROM monitor mode, then it is safe to remove it from the chassis. You can put the route processor in ROM monitor mode from IOS by issuing a reload command if the switch router is not configured to automatically boot. If the switch router is configured to automatically boot, it starts booting IOS again. To ensure that the route processor is in ROM monitor mode before removing it, use the following command:

redundancy prepare-for-cpu-removal

Execute this command on the route processor before removing it. Once this command is entered, the route processor goes to ROM monitor mode and stays there even if the system is configured to automatically boot. At this point, it is safe to remove the route processor from the system.

Enter this command after connecting to the console port of the route processor. If the system has a Y cable, then remove the Y cable and obtain a local connection to the route processor before the command is entered. Enter the command only on a route processor that is in IOS mode, even if it is the secondary route processor.

CSCdm31218

Symptom: Changing the MAC address for a bridge group member causes route processor bound packets on that interface to be discarded. For a port channel, the problem occurs when the first member is removed from the port channel.

Workaround: When an interface's MAC address is changed, remove the interface from its bridge group and then add it back into the bridge group.

CSCdm29650

Symptom: Incorrect coding of the information element "call state."

Information element "call state" incorrectly sets the coding standard to 00 (ITU-T coding standard) instead of 11 as specified in the PNNI specification. This can cause compatibility problems with other vendors' implementations.

Workaround: None.

CSCdm29529

Symptom: On the Catalyst 8540 MSR it is not possible to use a VCI value higher than 8191 for soft VCs and PVCs on the same interface module or port adapter where more than one VCI is configured.

Workaround: Use VCI values lower than 8192.

CSCdm29503

Symptom: The advertised priority is not updated for PGLs configured to match the advertised priority.

Workaround: None.

CSCdm29365

Symptom: The show controller command only displays information for even-numbered ports.

The show controller command for all odd-numbered ports in a 16-port OC-3c interface module displays the information for even-numbered ports.

Workaround: None.

CSCdm28633

Symptom: When a peer switch with UPLINK FAST enabled is connected to a Catalyst 8500 bridge group interface, the virtual MAC address of HSRP for an ACTIVE device in one of the member interfaces of the bridge group is programmed as a REMOTE entry.

Workaround: Use the clear bridge command to update the CAM table.

CSCdm26948

Symptom: Adjacencies are removed when a bridge table entry ages out. This causes traffic to be routed to the route processor, which might lead to high route processor utilization.

Workaround: Set the ARP timeout value to be less than the bridge age timer.

CSCdm25960

Symptom: When the fiber port is shut, level 1 does not have a mechanism for disabling the transmit signal. Disabling the fiber mode causes the level 1 chip to cut itself from the optical transceiver, which puts the transceiver in a floating state. The remote connection might pick up the bad signal sent by the transceiver as a good one and declare itself as up. The randomness of this signal causes flapping. This is evident when the fiber ports are connected between the following systems:

When the fiber ports on the Catalyst 8540 CSR and Catalyst 8510 CSR are connected, and the port on Catalyst 8540 CSR is shut, link flapping can occur on the Catalyst 8510 CSR fiber port.

When the fiber ports on two Catalyst 8540 CSRs are connected, link flapping can occur on the fiber port of one of the Catalyst 8540 CSRs when the fiber port on the other the Catalyst 8540 CSR is shut down.

When either a Catalyst 8540 CSR or a Catalyst 8510 CSR are connected to a Catalyst 5000, link flapping can occur on the fiber port of the Catalyst 5000 if it does not detect the shutdown on the fiber port of the Catalyst 8540 CSR or the Catalyst 8510 CSR.

Workaround: Change the hardware to send a constant signal (idle) when the port is shut.

CSCdm25943

Symptom: With 16 or more subinterfaces on a port channel, the following configuration might cause CPUHOG messages to appear:

[no] ip routing
[no] ipx routing
[no] bridge irb
[no] bridge-g [bridge-group-no]

Workaround: No workaround is needed; the route processor HOG messages should not affect the functionality of the device.

CSCdm25175

Symptom: The rate scheduler allocation (rsAlloc) update is accurately based on granularity of the mantissa value and might lead to oversubscription.

During the CAC process, for pure or partial rate scheduled connections, the rate actually programmed in the hardware might exceed the rate requested. This is particularly visible at very high rates, and is due to the granularity in the mantissa value (which cannot be fractional). However, the CAC allocates in its software structures only the rate requested. This might lead to an oversubscription of the rate scheduler.

This problem occurs at very high VC rates, where the CAC algorithm allocates slightly less than what the rate scheduler is programmed with (the difference is less than 0.03%).

Workaround: None.

CSCdm24192

Symptom: Failed attempts to reprogram a carrier module cause the Catalyst 8540 to hang.

Workaround: None.

CSCdm23579

Symptom: The switch router rejects calls with extended QoS parameters.

When ATM QoS for CDV is configured and you specify a soft VC (whether CBR or VBR-RT) from a UNI port which has negotiated a UNI 4.0 connection, this soft VC does not come up.

Workaround: None.

CSCdm23212

Symptom: The show hardware command does not display power supply IDPROM details.

Workaround: None.

CSCdm20899

Symptom: Under certain conditions, some Gigabit Ethernet interface module ports will not come up.

Workaround: If you observe this problem, you might need to upgrade your 10/100BASE-T interface module firmware. Contact your Cisco service representative for more information.

CSCdm20257

Symptom: The lane server-bus ethernet command might cause an unexpected exception when entered after deleting LANE clients from the subinterface.

Workaround: None.

CSCdm19783

Symptom: Under extreme low memory conditions, if a switch is configured with lots of hierarchical tunnels and LANE components are configured on the cpu port of the switch (or ATM interface of a router), removing a few subinterfaces or many several times can result in a crash. This removal without first cleaning up LANE configuration results in the loss of 6400 bytes of memory.

Workaround: Delete LANE configuration on a subinterface before deleting the subinterface itself.

CSCdm19670

Symptom: 1CT3 and 4CE1 do not support DS1 MIB (RFC 1406). Also 1CT3 does not support DS3 MIB (RFC 1407).

Workaround: None.

CSCdm19073

Symptom: The switch router rate scheduler rounds down the rates (when converting from bits per second to cells per second) when they should be rounded up.

Workaround: None.

CSCdm19018

Symptom: When a call setup message traverses a switch router running PNNI on the ingress side and IISP (version 3.0 or 3.1) on the egress side, the message might be corrupted.

Workaround: None.

CSCdm15900

Symptom: The Catalyst 8540 uses backward parameters in QoS information elements for point-to-multipoint calls.

This might cause incompatibility with other vendors' implementations.

Workaround: None.

CSCdm13967

%IPX-3-BADINSERT: Duplicate SAP entry insert attempted.

Symptom: The switch router returns a %IPX-3-BADINSERT message when a duplicate SAP entry is made.

Workaround: None.

CSCdm13198

Symptom: High route processor utilization if multicast traffic is high. When PIM protocol is configured, non-RPF multicast traffic is forwarded to the route processor.

Workaround: None.

CSCdm12694

Symptom: Cell loss occurs between unlike bandwidth interfaces, such as DS3 or T1 and OC-3c, that reside on the same carrier module which has functional image version 1.4 or earlier.

Workaround: Upgrade the carrier module FPGA image to release fi-c8540-scam.A.1-5 or later.

CSCdm08234

Symptom: Circuit emulation service (CES) might show an interface as UP following a loss of signal (LOS). Also, if the interface is shut down or the uplink ATM is not functioning, CES might fail to send an alarm indication signal (AIS).

Workaround: None.

CSCdm07857

Symptom: Messages appear when hot swapping a carrier module.

When you hot swap a carrier module into the Catalyst 8540 chassis, traceback messages such as the following appear on the console of the secondary route processor. These messages are harmless and can be ignored:

IDPROM in slot 10 not properly programmed
IDPROM in slot 12 not properly programmed
01:01:55: %SCHED-2-WATCH: Attempt to lock uninitialized watched semaphore (address0).

Workaround: None.

CSCdm07703

Symptom: When deleting the secondary route processor's start-up configuration, a CPUHOG message appears on the secondary route processor.

The delete command only removes files.

Workaround: Use the erase command to delete devices instead of the delete command.

CSCdm05738

Symptom: Due to a bad VCXO, a packet might delay on the switch router indefinitely, causing a software crash.

Workaround: None.

CSCdm05084

Symptom: CES port LEDs on the Catalyst 8540 are inconsistent with those of the LightStream 1010 ATM switch.

The Catalyst 8540 has an LED status configuration that is inconsistent with that of the LightStream 1010 ATM switch on CBR ports. When nothing is connected to the CBR port, the LED status on the LightStream 1010 ATM switch is as follows:

S1=red; S2=red; CD=off

When nothing is connected to the CBR port, the LED status on the Catalyst 8540 is:

S1=red; S2=red; CD=green

Workaround: None.

CSCdm04013

Symptom: AAL5 CRC errors are not accounted for at the physical interface.

The show atm interface command does not display CRC errors seen at the physical interface level. These errors are not logged under AAL5 CRC.

Workaround: None.

CSCdk93048

Symptom: When downloading an IOS image to the slot 0 Flash memory card on the Catalyst 8510 CSR by way of SNMP, the copy operation fails with a "copyUnknownFailure" message, and the formatting information on the Flash memory card is lost.

Workaround: When downloading an IOS image by way of SNMP, such as with the SWIM (Software Image Management) application of CiscoWorks2000, always use slot 1 instead of slot 0 as the target location of the IOS image.

CSCdk92832

Symptom: Some tx per-vc counters on both point-to-point and point-to-multipoint connections miscount cells. The cells are transmitted but not counted. The number of missed cells is small relative to the total number of cells counted is approximately 1% in the worst case.

Workaround: Upgrade the switch router feature card FPGA image to release fi-c8540-fc.A.4-17 or later.

CSCdk92661

Symptom: When you hot swap any interface module with an OC-12c interface module, the correct configuration for the OC-12c interface module in the port mode table does not come up properly.

Workaround: Upgrade the switch router feature card FPGA image to release fi-c8540-fc.A.4-17 or later.

CSCdk91364

Symptom: In the output of the show atm vc command, all of the packet counters are incorrectly displayed as zero.

Workaround: None.

CSCdk90147

Symptom: A crash might occur while removing subinterfaces using the no interface command.

When an active VP tunnel subinterface is deleted, a software crash might occur.

Workaround: Shut down the subinterface before deleting it.

CSCdk90091

Symptom: A software crash might occur on the switch router running software release 11.2(15)WA3(6). The crash is related to PNNI; the crashing function is pnni_link_av.

Workaround: None.

CSCdk89501

Symptom: Online insertion and removal of port adapter modules can result in a bus error.

Workaround: Avoid the online insertion and removal of port adapter modules.

CSCdk89275

Symptom: Occasionally, the show controllers interface-name command can bring down an interface and the line protocol. The condition that leads to this scenario is random and very infrequent. The end result is that routing/bridging stops on this interface.

Workaround: None.

CSCdk89079

Symptom: OIR INSCARD messages display during boot.

Workaround: None.

CSCdk88859

Symptom: The Frame Relay port adapter firmware might report CRC errors on a PVC if it receives traffic using the same VPI/VCI/DLCI while the PVC is configured.

The errors only occur while the firmware is still configuring the VC. Once the PVC is configured, the CRC errors stop. Since the frames appear like zero-length AAL5 packets while the firmware is still configuring the VC, the firmware does not increment the discard bytes counter, but does increment the discard frames counter due to the CRC errors.

Workaround: Do not allow traffic to pass on the VC while it is being configured.

CSCdk87118

Symptom: While toggling the interfaces on the peer switch (the LightStream 1010 ATM switch), the following error message is occasionally displayed on the Catalyst 8540:

04:09:08: process_cubi_cell_list: cubi_oam_upcall returned an error

This occurs when a LECS is configured on the route processor port along with 10 LES/BUS/LECs on the 10 subinterfaces on the route processor port.

Workaround: None.

CSCdk82832

Symptom: Unpredictable results might occur if the route processor scheduler allocation is changed in the configuration file.

Workaround: Remove the scheduler allocate command from the configuration file. We recommend that you do not change the default values for this command.

CSCdk73492

Route processor HOG message appears when activating OSPF on a large port channel configuration.

Symptom: A route processor HOG message appears when OSPF is activated on a port channel interface with more than 30 subinterfaces.

Workaround: The operation succeeds even if this message appears. No action is necessary.

CSCdk83334

Symptom: Point-to-multipoint PVC preservation across a route processor switchover is not fully supported.

If traffic is flowing through a point-to-multipoint connection when a route processor switchover takes place, then some of the leaves of the connection might not be restored properly. Traffic might continue to flow through all the leaves of the connection even after the switchover, but the output of the show atm vc command might show NO HW RESOURCE for some of the leaves of the connection. In the absence of traffic, all the leaves of a point-to-multipoint connection will be restored properly across a route processor switchover.

Workaround: If possible, shut down traffic on all point-to-multipoint connections before a route processor switchover.

CSCdk82708

Symptom: When running tag switching, no tag is created for the default route.

Workaround: None.

CSCdk80021

Symptom: The sysConfigName MIB variable value is not set correctly.

If the system is set to autoboot and no explicit boot image is specified, the system boots the default image from the bootflash. In this scenario, the show version command displays the image name as "default image" instead of the actual image name. The MIB variable sysConfigName also returns an empty value.

Workaround: None.

CSCdk79426

Symptom: Soft VPs and PVPs cannot coexist due to VPI allocation errors.

When creating soft VPs, the VPI value allocated on the switched part of the soft VP path might collide with existing configured PVPs.

Workaround: There are two ways to get the soft VP up:

Remove the PVP.

Create a PVP using the same VPI value on the peer switch router. This forces the peer switch router to allocate a different VPI value for the soft VP.

CSCdk78469

Symptom: PNNI does not correctly clean up and release some of its data structures after process termination. A PNNI process is terminated when the associated node is either disabled or removed. As a result of not freeing the data structures, the associated memory is unavailable until the next reload.

Workaround: None.

CSCdk77032

Symptom: The PNNI SNMP agent is not able to discover and allow PNNI-related configurations on ATM subinterfaces.

An alignment error message is printed when an SNMP walk (or other SNMP get next) request is entered.

Workaround: None.

CSCdk76280

Symptom: Connections might fail when the connect message includes an end-to-end delay IE. A Catalyst 8540 that is an intermediate switch router passes a bad CONNECT message from one side to another. The CONNECT message shows up as a CONNECT packet that is longer than the actual contents, with junk bytes at the end.

Examples of these connections include UNI 4.0, CBR, and VBR-rt.

Workaround: None.

CSCdk71688

Symptom: Reprogramming a network clock module causes a processor reset.

Reprogramming the network clock module on the primary route processor causes the route processor to reload after the download is complete. Power cycle the switch router to make the newly loaded image active.

Workaround: None.

CSCdk71268

Symptom: Reprogramming a carrier module might cause the Catalyst 8540 to hang and not reboot.

After successfully reprogramming a revision 4.0 carrier module with FPGA 1.4, the Catalyst 8540 might hang. To recover the switch router, remove the carrier module before rebooting.

Workaround: None.

CSCdk69639

Symptom: Disabling tag switching on an interface that carries tagged VCs (TVCs) does not remove the TVCs. Reenabling tag switching on that interface will put it in the "not TDP ready" state.

Workaround: None.

CSCdk62547

Symptom: The DS1 MIB objects do not work for T1/E1 ATM port adapters and CES port adapters.

Workaround: None.

CSCdk52436

Symptom: On a Catalyst 8540 system configured with 32 MB of RAM, IPC traffic between the port adapter driver and the firmware can experience a transient failure when the port adapter firmware crashes under heavy traffic conditions. The port adapter recovers from this transient failure if it is reset after waiting for about 2 minutes.

This IPC failure, which is due to an unexpected firmware crash under a heavy load, does not occur on a Catalyst 8540 system configured with 64 MB of RAM.

Workaround: None.

CSCdk47516

Symptom: Tag switching and Tag Discovery Protocol (TDP) might cause memory fragmentation.

While running tag switching with a very large number of destinations, continuous toggling of VC merge (which forces all the TDP sessions to restart) on the switch router for a period of time (for example, overnight) causes memory fragmentation in the TDP process.

Workaround: None.

CSCdk42052

Symptom: When loading a software version 11.3 or later image on a switch router with 11.2 or earlier image, LECs and other LANE components might fail to come up if they are configured using an ATM address whose first 19 bytes are the same as the active ATM address of the switch router.

The ATM address of the switch router along with the first 128 values for its selector byte should be reserved for use by PNNI. Starting with the 11.3 software version, PNNI supports hierarchy and registers an ATM address for all PNNI nodes using the switch router ATM address with various selector byte values.

Workaround: If LANE components fail to come up because their ATM addresses collide with the reserved ATM addresses for PNNI, reconfigure the LANE components using different addresses. It is recommended that LANE applications use the addresses shown by the show lane default-atm-addresses command, which will eliminate this problem.

CSCdk33601

Symptom: ADD party requests over a VP tunnel do not work.

On a source node, when adding a subsequent leaf to a VP tunnel that is out of bandwidth, PNNI might reject the route request (for the leaf) leading to an eventual rejection of the ADD party by signaling.

Workaround: None.

CSCdk30912

Symptom: An unnecessary lookup for a network configuration file occurs after a route processor switchover.

When a route processor switchover occurs, the new primary route processor that is taking over might look for configuration files from a network server that might not exist. These network configuration file lookups will timeout. This causes some delay during the switchover process.

Workaround: None.

CSCdk27725

Symptom: Snooping error: %ATMCORE-3-INTERNAL_ERROR:connUpdateFreeVxiMap:bitMapInfo

When snoop-VC is configured on a port, the switch router returns this internal error message:

%ATMCORE-3-INTERNAL_ERROR: connUpdateFreeVxiMap: bitMapInfo null ptr

Ignore this message; it does not affect the snooping functionality.

Workaround: None.

CSCdk26482

Symptom: The following error message appears when using the show atm interface resource atm card/subcard/port.subport command:

Tunnel:%ATMCORE-3-INTERNAL_ERROR: show_atm_int_rm: Cannot find phylo

This error message appears because the tunnel specified in the command has been deleted and the structures pertaining to that tunnel have been released.

Workaround: None.

CSCdk22791

Symptom: When a large amount of data is sent out of the Ethernet interface, the interface might become overwhelmed and start generating the following error message:

%SONICT-3-INTERNAL_ERROR: sonic_send: no free tbufs

The interface stops sending data and the transmitter remains stuck.

Workaround: Enter a shutdown/no shutdown command sequence on the interface.

CSCdk22484

Symptom: When ATM accounting is enabled, an exception might occur because resources at the destination switch router are not available.

Workaround: None.

CSCdk17977

Symptom: Another vendor's router running UNI 4.0 cannot connect a VC to a Cisco router running UNI 3.1 by way of a Catalyst 8540.

Workaround: None.

CSCdj85853

Symptom: When you set the ROM monitor environment variable to boot a nonexistent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch router hangs during the subsequent reload command issued by the software.

Workaround: Power-cycle the switch router and send a break character to the switch router within 60 seconds to force it to the ROM monitor prompt. You can then manually reboot the switch router and reconfigure the environment variable.

CSCdj84379

Symptom: The granularity provided by the switch processor scheduling hardware does not allow an exact match of all requested cell rates. To satisfy the traffic contract guarantee, the next higher available scheduling value is used. A shaped VP tunnel is used frequently to pass data to a WAN VP trunk, and limits the traffic transmission to the scheduled rate. This can cause cells to be dropped in the WAN. Any dropping must be done prior to multiplexing onto the VP, so that a packet discard can be performed.

Workaround: None.

CSCdj84344

Symptom: There is a small divergence in the measured output of the shaped VP tunnels at rates of 90 Mbps and above.

Workaround: None.

CSCdj82930

Symptom: Open Shortest Path First (OSPF) does not recognize more than four parallel interfaces. This might cause some tag switching VCs (TVCs) to not switch to other interfaces if a tunnel carrying the TVCs is shut down.

Workaround: Enter a clear ip route command on the switch router for the interface that was shut, or a clear ip route command on all the switch routers to bring everything back up. If the clear ip route command does not bring everything back up, enter a shutdown/no shutdown command sequence on the UNI interfaces of the switch router that had the closed physical interface.

CSCdj80396

Symptom: The switch router issues CPU hog messages while setting up many calls.

With a large number of connections installed, a show atm vc command may take longer than 2 seconds to complete. This produces a %SYS-3-CPUHOG error message from the scheduler.

Workaround: If information about a specific VC is desired, to specify the interface and the VPI/VCI needed, use the show atm vc interface command card/subcard/port vpi vci

CSCdj71109

Symptom: The ATM switch router does not currently support maxvc-number negotiation through ILMI.

Workaround: None.

CSCdj68412

Symptom: If there are multiple parallel paths to the same destination on the ATM switch router with a switch processor feature card installed, the tag switching VCs (TVCs) should be load balanced on a per network prefix basis over these parallel paths (up to a maximum of four parallel paths) instead of being VC merged. Load balancing does not happen in some cases and the TVCs might be VC merged and go out of the switch router as a single VC.

Workaround: None.

CSCdj47998

Symptom: The Catalyst 8540 Ethernet connection does not receive CDP multicast packets. However, the Catalyst 8540 does send out CDP multicast packets.

Workaround: None.

CSCdj31762

Symptom: SNMP SET to a CES port causes the switch router to hang.

If you attempt to do an SNMP SET on the ifAdminStatus of a virtual ATM port associated with a CES port adapter, the switch router stops working.

Workaround: None.

CSCdj11070

Symptom: The CDP configuration for a LEC cannot be saved to NVRAM.

When disabling CDP on the atm0.x interface, which has been configured as a LEC, the information is not saved to NVRAM and does not appear in the show running-config command display. CDP is disabled, but the setting reverts to enabled after a reload.

Workaround: None.

CSCdj01016

Symptom: You can create variable bit rate (VBR), available bit rate (ABR), and unspecified bit rate (UBR) VCs across the switch router with peak cell rate (PCR) values greater than the interface line rate. However, the actual allocated bandwidth continues to be:

VBR: sustained cell rate (SCR) + sustained-cell-rate-margin-factor x (PCR - SCR).

ABR, UBR: no bandwidth is allocated.

Workaround: None.

CSCdi92142

Symptom: A LECS expects all LESs to establish an individual control VC to the LECS to validate clients.

If different emulated LANs (ELANs) are configured on multiple subinterfaces of the same physical interface, then all LESs multiplex the control messages which validates the clients into a single VC.

For example, see the following LES router configuration:

atm1/0.1 sysa_70k_31_a1.1_LAN sysa_70k_31_a1.1_LAN
atm1/0.2 sysa_70k_31_a1.2_LAN sysa_70k_31_a1.2_LAN
atm1/0.3 sysa_70k_31_a1.3_LAN sysa_70k_31_a1.3_LAN
atm1/0.4 sysa_70k_31_a1.4_LAN sysa_70k_31_a1.4_LAN

This configuration of a LECS sends the following warning messages to the console stating that a LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan
'sysa_70k_31_a1.1_LAN'
%LANE-4-LECS_WARNING: interface ATM0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan
'sysa_70k_31_a1.2_LAN'
%LANE-4-LECS_WARNING: interface ATM0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan
'sysa_70k_31_a1.3_LAN'

The clients are still allowed to join the ELAN. Disregard the warning message.

Workaround: None.

CSCdi74229

Symptom: When more than 1000 SVCs are active on an interface and the shutdown command is entered, all SVCs on that interface are released and the following message appears:

%SYS-3-CPUHOG

This message indicates that the release process runs for a long time before returning control to the kernel, which can then schedule other tasks. This process does not affect normal operation of the switch router.

Workaround: None.

CSCdi55937

Symptom: Remote defect identification (RDI) cells (sent by an endpoint in response to alarm indication signal [AIS] cells generated at an intermediate switch router with a fault condition on an interface) are not propagated beyond the intermediate switch router. The intermediate switch router removes the connection leg entries for both interfaces participating in the connection when a fault is discovered on one of the interfaces, even though the other interface might still be up. As a result, the RDI cells are dropped at the intermediate switch router.

Workaround: None.

The following ACLs are not supported with the ACL daughter card:

ACL for GEC, FEC, or BVI

Dynamic ACL

Reflexive ACL

IPX extended ACL

ACL logging

AppleTalk Restrictions

We recommend that you evaluate the level of CPU utilization and performance in your switch router before turning on AppleTalk. Unlike IP and IPX, AppleTalk routing and processing in the Catalyst 8540 is accomplished by the switch processor, not the interface module. This means that routing AppleTalk packets consumes more processing time than routing other protocol packets. In a switch with a sustained high CPU utilization, turning on AppleTalk could result in longer convergence times for routing protocols like EIGRP. AppleTalk packet throughput is dependent on the amount of available CPU processing power.

ATM Router Module Restrictions

The Catalyst 8540 MSR ATM router module does not support the following features:

Point-to-point subinterfaces. Only point-to-multipoint subinterfaces are supported.

Tag-edged router functionality

Fast Simple Server Redundancy Protocol (FSSRP)

Bridging for multiplexing device encapsulation

Protocol Independent Multicast (PIM) IP multipoint signalling

PIM nonbroadcast multiaccess (NBMA)

PIM over ATM multipoint signalling

Translation from IP quality of service (QoS) to ATM QoS

Resource Reservation Protocol (RSVP) to ATM SVC

PVC management using ILMI

Access lists for ATM to ATM routing

Half-bridge devices

RFC 1577 SVCs

RFC 1483 MUX encapsulation

Appletalk over 1483 VCs

VLAN Encapsulation Restrictions

The four adjacent ports (such as 0-3 or 4-7) on a 10/100 Fast Ethernet interface must all use the same VLAN encapsulation, that is, either 802.1Q and native, or ISL and native.

EtherChannel Restrictions

When assigning Ethernet interfaces to an EtherChannel, all interfaces must be either Fast Ethernet or Gigabit Ethernet. You cannot mix Fast Ethernet and Gigabit Ethernet interfaces within a single EtherChannel.

Maximum Path Restriction for EIGRP or OSPF

Catalyst 8540 interface modules support a maximum of 2 paths. To improve EIGRP or OSPF convergence, set the maximum-paths for the router to 2, using the following command:

8540(config)# router eigrp 109
8540(config-router)# maximum-paths 2

Port Snooping Restrictions

The snooping source port and destination port cannot be the same port.

You can only snoop with one source port and one destination port.

Snooping configuration information is not saved in NVRAM.

You cannot snoop a port that is part of a bridge group.

Eight-Port Gigabit Ethernet Restrictions (Catalyst 8540 CSR)

The eight-port Gigabit Ethernet interface module is supported on the Catalyst 8540 CSR only. This section describes limitations of the eight-port Gigabit Ethernet interface module.

Ports Per Bridge Group Restrictions

The eight-port Gigabit Ethernet interface module installed in a Catalyst 8540 CSR can support a maximum of 128 ports per bridge group.

Port Channel Restrictions

If your Catalyst 8540 CSR has an eight-port Gigabit Ethernet interface module, you cannot create a port channel that has some members on that module and others on other modules. All port channel members must reside on the same Gigabit Ethernet interface module.

Also, if your switch router has an eight-port Gigabit Ethernet interface module, port channel IDs 57 to 64 are reserved, and cannot be assigned to other external interfaces. If you assign a port channel ID number greater than 56, the system will respond with the following message:

Port channel with ID > 56 cannot be created.

If you have already assigned port channel IDs 57 to 64, you must reassign them before installing an eight-port Gigabit Ethernet interface module.

If your switch router does not have an eight-port Gigabit Ethernet interface module, you can assign port channel ID numbers up to 64.

Online Insertion and Removal of Interface Modules Restrictions

The following restrictions apply to the online insertion and removal (OIR), also known as hot swapping, of interface modules on the Catalyst 8500 CSR:

Wait at least one minute after removing an interface module before inserting a new one.

While the device is operating, remove only one interface module at a time.

OIR of the eight-port Gigabit Ethernet interface module is supported in Cisco IOS Release 12.0(5)W5.13 and later releases.

Online Diagnostics Restrictions

Online diagnostics, such as access tests, online insertion and removal (OIR) tests, and snake tests, detect and report hardware failures in the Catalyst 8540 during system bootup and operation. The following restrictions apply to the OIR (also known as hot swapping) tests and the snake tests on the Catalyst 8500 CSR:

The OIR tests support all Layer 3 interface modules, with the exception of the ATM uplink interface module and the eight-port Gigabit Ethernet interface module.

The snake test on the Catalyst 8540 CSR is supported on the enhanced Gigabit Ethernet interface module, the ATM uplink with enhanced Gigabit Ethernet interface module, and the Packet-over-SONET uplink with enhanced Gigabit Ethernet interface module. Snake tests are not supported on either the Fast Ethernet interface modules or the Gigabit Ethernet interface modules.


Note Access tests are supported on all Layer 3 interface modules. Refer to the "Configuring Online Diagnostics (Catalyst 8540)" section in the Layer 3 Switching Software and Feature Configuration Guide for additional information.


FPGA Upgrade Restriction

On an 8540, the reprogram command for upgrading the FPGA on the switch processor requires power cycling the box after completing the FPGA download.

1000BASE-ZX GBIC Restriction

The Catalyst 8540 MSR switch routers support extra long haul (1000BASE-ZX) GBICs as follows:

Catalyst 8540 MSR: A maximum of 12 1000BASE-ZX GBICs per system to comply with FCC Class A emissions (CFR 47 Part 15), or 8 1000BASE-ZX GBICs per system to comply with EN55022 Class B emissions (CISPR22 Class B).

Catalyst 8540 CSR: A maximum of 12 1000BASE-ZX GBICs per system to comply with FCC Class A emissions (CFR 47 Part 15), or 8 1000BASE-ZX GBICs per system to comply with EN55022 Class B emissions (CISPR22 Class B).

Bridge-Group Virtual Interface Restriction

A Bridge-Group Virtual Interface (BVI) is a virtual interface within the campus switch router that acts like a normal routed interface. A BVI does not support bridging, but it actually represents the corresponding bridge group to routed interfaces within the switch router. The interface number is the link between the BVI and the bridge group.

Layer 3 switching software supports the routing of IP and IPX between routed interfaces and bridged interfaces in the same router, in both fast-switching and process-switching paths. BVIs do not support IP multicast routing.

Catalyst 8540 Route Processor and Switch Module Redundancy

The Catalyst 8540 CSR supports the use of redundant route processors and switch modules. The second route processor would be installed in slot 8, and an additional switch module would be installed in slot 6.

Route Processor

There are some precautions that need to be taken before removing a route processor module from a chassis that is powered-up. If a route processor module that is currently running IOS is removed from the chassis in a skewed manner such that the left side of the processor comes out before the right side does, the traffic flowing through the device might stop flowing.

To avoid this, make sure the route processor module that is being removed is currently at the ROM monitor prompt; it is then safe to remove it from the chassis. One way to get the system into ROM monitor from IOS is to issue a reload command. This will work if the system is not configured to auto-boot. If the system is configured to auto-boot, it starts booting IOS again.

Since you need to ensure that a route processor is in ROM monitor before removing it, the redundancy prepare-for-cpu-removal command has been added to take the system to the ROM monitor prompt. Execute this command on the route processor being removed before removing it. Once this command is issued, the route processor will go to the ROM monitor prompt and stay there even if the system is configured to auto-boot. At this point it is safe to remove the route processor from the system.

Switch Modules

If a Catalyst 8540 has three switch modules, then by default the switch modules in slots 5 and 7 come up as active, and the one in slot 6 comes up as the standby. If you wish to change this default, there is a command that lets you select the "preferred" switch module slots. This command is a privileged exec level command with the following format:

redundancy preferred-switch-card-slot slot#1 slot#2

Two unique preferred slots must be specified. The range of the slot value is 5 to 7. If one of the preferred slots is not a currently active switch module, you are informed of this and asked if the system should change the active switch modules to the preferred switch modules. If such a switch-over occurs, all the active connections in the system will be reinitialized. If you wish to continue, then the preferred switch modules become active, and the other switch module becomes the standby. This configuration will remain in effect until either one of the active switch modules is removed.

The preferred switch module configuration is preserved across route processor switch-overs. However, the preferred switch modules setting will be lost if the system is power-cycled or if both route processors are reloaded to the ROM monitor.

Autonegotiation (Catalyst 8540 CSR)

Beginning with Cisco IOS Release 12.0(5)W5(13) software, the autonegotiation feature for speed and duplex on 10/100BASE-T Ethernet ports defaults to "on." This means that for each port, the Catalyst 8540 CSR automatically detects the port speed (10 Mbps or 100 Mbps) and duplex of the peer port, if that port also autonegotiates.

To override autonegotiation and set a port to 10 Mbps operation, issue the following command:

(config-if)# speed 10

To set a port to 100 Mbps operation, issue the following command:

(config-if)# speed 100

To set the duplex value for a port to full-duplex, issue the following command:

(config-if)# duplex full

To set the duplex value for a port to half-duplex, issue the following command:

(config-if)# duplex half

Caution If you connect a Catalyst 8540 CSR running Cisco IOS Release 12.0(5)W5(13) software to a switch router running in forced full-duplex mode, you might encounter symptoms such as high collision rate or reduced throughput, as the Catalyst 8540 unsuccessfully tries to autonegotiate with the other device. When autonegotiation fails, the Catalyst 8540 defaults to half-duplex operation, which causes a mismatch between it and the other device. Possible workarounds include forcing the Catalyst 8540 CSR to operate in full-duplex mode or removing the full-duplex command from the other device.

Incompatibility (Catalyst 8540 CSR)

When you connect a Catalyst 8540 CSR to a Catalyst 5000 100BASE-FX MM Ethernet interface module using ISL, ensure that the hardware version on the Catalyst 5000 interface module is 1.3 or higher. You might experience connectivity problems between the Catalyst 8540 CSR and the Catalyst 5000 if the hardware version on the Catalyst 5000 Ethernet interface module is lower than 1.3.

Interoperability

You can use Catalyst 8540 CSR interface modules in a Catalyst 8540 MSR chassis with an MSR route processor and switch modules. Use only CSR (Ethernet) interface modules, and load the CSR software image on the MSR.

Starting with the following software releases, hardware and software functionality interoperability exists between CSR interface modules and MSR interface modules by way of the ATM router module on the MSR chassis running an MSR image:

Cisco IOS Release 12.0(4a)W5(11a) supports interoperability between CSR interface modules and MSR interface modules by way of the ATM router module on the Catalyst 8540 MSR running an MSR image.

Cisco IOS Release 12.0(10)W5(18b) supports interoperability between CSR interface modules and MSR interface modules by way of the ATM router module on the Catalyst 8510 MSR running an MSR image.

Y2K Compliance

The Catalyst 8540 MSR system running Cisco IOS Release 12.0(0.6)W5(1) or later have been certified as Y2K Compliant. For more information, see the following URL: http://www.cisco.com/warp/public/752/2000/.
