Introduction

The Catalyst 8510 and LightStream 1010 switch provide 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.


Note The ATM switch processors (hardware version 4.0 or higher) and all port adapters can be installed in the Catalyst 5500 switch chassis.


The Catalyst 8510 CSR belongs to a class of high-performance Layer 3 switch routers. It is optimized for the campus LAN or the intranet and provides both wirespeed Ethernet routing and switching services.

Memory Requirements

Catalyst 8510 MSR and LightStream 1010

The DRAM memory configuration is 64-MB DRAM (MEM-ASP64M), which is the default for both the Catalyst 8510 and the LightStream 1010 switch platforms.

Catalyst 8510 CSR

Table 1 lists the default Flash and DRAM memory for the Catalyst 8510 CSR, as well as memory upgrade options.

None


To download and store a copy of the Catalyst 8510 CSR software image, we recommend using a minimum 20 MB Flash PC Card, which will allow you to have two or more images installed at the same time.

The Catalyst 8510 CSR boots from its onboard Flash memory by default. To change this default to boot from a Flash PC Card instead, you must change the configuration register setting to 0x2102. Refer to the Layer 3 Switching Software Feature and Configuration Guide for more information.

Hardware Supported

Table 2 lists the interfaces supported by both the Catalyst 8510 MSR and LightStream 1010 switch and Cisco IOS Release 12.1(14)EB1 and their minimum software release requirements. All platform specific requirements are noted in the table. Table 3 lists this information for the Catalyst 8510 CSR.


Note Although minimum software versions are listed, we strongly recommend that you use the latest available software release for all Catalyst 8510 and LightStream 1010 hardware.

Determining Your Software Release

To determine the version of Cisco IOS software currently running on either the Catalyst 8510 or the LightStream 1010 switch, log in to the switch and enter the show version EXEC command. The following is sample output from the show version command. The version number is indicated on the second line as shown below:

Cisco Internetwork Operating System Software IOS (tm) LS1010 W5-5 Software (LS1010-WP-M), Version 12.1(14)EB1

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

Other Firmware Code

Some of the port adapters supported on the Catalyst 8510 and LightStream 1010 switch have upgradeable 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 FPGA and 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 section "Maintaining Functional Images (Catalyst 8510 and LightStream 1010)" in the chapter "Managing Configuration Files, System Images, and Functional Images" in the ATM Switch Router Software Configuration Guide.

Caveat Symptoms and Workarounds

This section summarizes caveat symptoms and suggested workarounds for the Catalyst 8510 switch and the LightStream 1010 switch.


Note The maximum number of ELAN LES/BUS pairs that the ATM switch processor interface supports is 10. On configuring a Frame Relay NIW/SIW PVC, a small number of discarded frames are occasionally seen due to CRC errors. These discards happen even without passing traffic.


CSCin44348

Symptom: The Frame Relay retry-interval is shown twice in the running configuration. This means the configured Frame Relay Soft VCs are not preserved after an image reload or a route processor switchover.

Workaround: None.

CSCin41597

Symptom: PNNI routing fails from one access device to a complex-peer in some branches. For example, in the following network example, calls from the Ls1010 switch to an interface on the Catalyst 8540 switch are not set up.

But, calls from the Catalyst 8540 switch to the Ls1010 switch are set up correctly. If the Catalyst 8540.2 switch is configured as a simple single-level hierarchy the calls originated from either switch to the other switch are set up without any problems.

Workaround: Configure the complex node (Catalyst 8540.2 switch) as a simple hierarchy.

CSCin40363

Symptom: The switch crashes when you run the no tag-switching mtu command.

Workaround: None.

CSCin37548

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

The switch reloads when:

Through a console session run the show atm pnni topology 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.

Through a console session run the show atm pnni neighbor 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.

Through a console session run the show atm pnni background routes admin-weight 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.

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:

Through a console session run the show atm pnni topology 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 session causes spurious memory access.

Through a console session run the show atm pnni aggregation node border-detail exception-detail 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.

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.

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 8510 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.

CSCin29715

Symptom: If a Frame Relay-Frame Relay PVC is deleted through SNMP Resource Management the information is incorrect in the show frame-relay interface resource serial card/subcard/port:chn_grp_# command display.

This allows for creation of more VCs than the physical bandwidth available.

Workaround: Delete and recreate the channel group.

CSCin27583

Symptom: If a marker cell has been queued for a leaf and at the same time a new party is attempting to be installed, the add party fails and the following error message is seen:

00:04:26: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL 00:05:30: %ATMSIG-3-FAILXCONN: Xconnect failed, xconn fail -Traceback= 607B910C 607BB960 607C6950 607B3538 607B3640 600D2FAC 600D2F98 00:05:30: ATMSIG(1/0/3:0 0,79 - 0045/25): (vcnum:0) XConnected failed To 00:05:30: ATMSIG(1/1/0:0 0,945 - 0220/25): (vcnum:0) 00:05:30: ATMSIG: CONNECTION MANAGER/CAC Xconn install request Port A - (1/0/3) : 0 vpi = 0; vci = 79 Port B - (1/1/0) : 0 vpi = 0; vci = 945; new vpi = 0; new vci = 945 existing vpi/vci for leg B 00:05:30: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL

Workaround: The point-to-multipoint Soft-PVC party will come up because of the Soft-PVC retry.

CSCin23067

Symptom: The number of point-to-multipoint Soft-PVC connections on the destination switch displayed by the output of the show atm state command might display conflicting results with the output of show atm vc conn-type soft cast p2mp command. The show atm vc conn-type soft cast p2mp command displays the correct status of the point-to-multipoint Soft-PVC connections on the switch.

Workaround: None.

CSCin22597

Symptom: The "Number of soft vc re-try attempts:" value shown in the output of the show atm soft-vc p2mp interface atm card/subcard/port vpi vci command is always one greater than the actual number of re-try attempts made.This is because the counter is incremented on starting the party retry timer and not when the timeout happens and the signalling message is sent.

Workaround: None.

CSCin19522

Symptom: For Frame Relay Soft VCs that use frame size other than 250 (default), the CTTR should not be modified.


Note This DDTS is valid for release 12.1EB only.


Workaround: Delete the Soft VC from the configuration and re-create with new a CTTR.

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.

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.

CSCin12950

Symptom: Packets received with a destination multicast MAC address and destination unicast IP address, are forwarded to the Route Processor and then forwarded back out on the VLAN where the packets were received.

Workaround: None.

CSCin12417

Symptom: An ATM interface might stick in the state "going down" if the PVC is created from the ATM Router Module with VCI "34" on the ATM side. For example, "atm pvc 2 35 pd on interface ATM0/0/0 7 34" causes the line to flap "up" and "down".


Note The problem is not seen with any other VCI on the ATM side.


Workaround: Recreate the PVC using any VCI other than "34" on the ATM side.

CSCin12744

Symptom: Signaling is reset on other interfaces of the device that are not connected to the peer switch being reloaded.

Workaround: None.

CSCin10542

Symptom: After you configure a Point-to-Multi Point connection, if you try to remove the connection from the leaf side, the following message is displayed:

% PVC de-configuration not allowed with snooping on!! % De-configure snooping first.

Workaround: Delete the PVC or PVP from the root end.

CSCin09850

Symptom: When an ATM Soft-VC or Soft-VCP is configured between two interfaces of a Catalyst 8540 MSR using a particular VPI, and a Soft-VC or Soft-VCP is configured with the same VPI, the following error appears:

%ATMCORE-3-INTERNAL_ERROR: atmCore_connAllocateHalfLeg: return resource err.2

The internal error message should not appear when the Soft-VC or Soft-VCP configuration fails.

Plus, the following expected message is seen more than once:

connection creation fails:vpi/vci has been used

The internal error message is not seen when a PVC configuration on an interface is followed by a PVP configuration that uses the same VPI. Also, the internal error is not seen when the interface on which the configuration is being done does not have the resources required by the Soft-VC or Soft-VCP.

After the configuration is executed and then fails, this causes the allocation of the bandwidth requested by the CBR VC even though no VC actually exists. If, for example, N kbps is free on an interface, and a Soft-VC is configured from that interface with a VPI-VCI already in use and uses a CTTR of N kbps, the configuration fails, but all N kbps that were free on that interface are lost. This bandwidth loss is seen only with the CBR service-category.


Note Using the shutdown and no shutdown commands on the interface does not recover the lost bandwidth.


Workaround: For the Catalyst 8540 MSR, if you switchover the route processor it recovers the lost bandwidth on the interface. No workaround exists on the Catalyst 8510 MSR.

No workaround exists for the following error message:

"%ATMCORE-3-INTERNAL_ERROR: atmCore_connAllocateHalfLeg: return resource err.2

CSCin09752

Symptom: If an IMA group exists between a Catalyst 8540 and Catalyst 8510 switches with CBR soft VCs configured between the switches and a link of the IMA group is shut down or fails, the IMA interfaces still display the pervious bandwidth value. This bandwidth value is greater than the actual resources available on the interface and the soft VCs still appear as "up" on both the Catalyst 8540 and Catalyst 8510 switches. This continues to happen as more links are shut down or fail until the 2 CBR soft VCs that require the resources of 7 E1 links still appear as "up" with only 1 E1 link actually "up" between the IMA interfaces and the other 6 links that are shutdown.


Note This behavior is seen when the links are either deleted from the IMA group or that are shutdown.


Workaround: Use the shutdown and no shutdown commands on the IMA group and it will display the correct values of available and allocated bandwidth.

CSCin09205

Symptom: If a VC is down when the switch is reloaded, the ARM subinterface stays UP even though the OAM-state is OAM-Down.

Workaround: Bring the VC UP at least once after a reload.

CSCin09194

Symptom: If you configure OAM on a PVC while it is down, the OAM state of the VC is displayed as "not applicable" instead of "OAM-Down" and never changes. This means OAM cells are not sent even after the VC comes UP. This only occurs if AIS is not enabled for the VC.

Workaround: Configure OAM for a VC only when it is in UP state.

CSCin06705

Symptom: Subinterfaces of route processor and ATM router module ports are not registered with SNMP ifTable.

Workaround: None.

CSCin06080

Symptom: On a LightStream 1010 switch with an E1interface connection, Detailed Device Report shows "slot number : N/A" but should display the actual interface slot number.

Workaround: None.

CSCin02864

Symptom: On interface ATM0, while breaking the packet into cells, when the MTU size configuration is checked it is checked for the cross-connect ATM interface and not for interface ATM0 itself. This means if the size of the packet exceeds the configured MTU on the cross-connect ATM interface, the following error is displayed:

%LINK-4-TOOBIG: Interface ATM1/1/3, Output packet size of 2008 bytes too big

Workaround: There are two possible workarounds for this condition: either change the MTU size on both ATM interfaces back to the default using the command no mtu in interface configuration mode, or change the MTU configuration on interface atm 0 to match the MTU configuration on the cross-connect interface using the mtu # interface configuration command.

CSCea72899

Symptom: Soft PVC does not come up.

If a Soft PVC originates from a Catalyst 8510 MSR or LightStream 1010 ATM switch is 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 8510 MSR 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

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

show atm pnni neighbor --- Neighbor Name: unknown, Node number: 40 Neighbor Node Id: 88:160:xx.348F8001BBFC00000BA06F10.408021810A00.00 Neighboring Peer State: Full Link Selection For CBR : minimize blocking of future calls Link Selection For VBR-RT : minimize blocking of future calls Link Selection For VBR-NRT: minimize blocking of future calls Link Selection For ABR : balance load Link Selection For UBR : balance load Port Remote Port Id Hello state ATM12/0/3 1281000 2way_in (Flood Port) --- Switch# show atm route P I 40 0 UP 0 39.348f.8001.bbfc.0000.0ba0.6f10/104 ---

But, if the show atm pnni dtl node 40 ubr command is used:

*Apr 10 23:11:21.218: PNNI: UBR route request from ATM_OWNER_UNKNOWN *Apr 10 23:11:21.218: PNNI: To node 88:160:xx. 348F8001BBFC00000BA06F10.408021810A00.00 *Apr 10 23:11:21.218: PNNI: selected target node 40 *Apr 10 23:11:21.218: priority: 2 (40 0) pnni-remote-internal *Apr 10 23:11:21.218: PNNI: Compute On-Demand Route Based On Admin Weight *Apr 10 23:11:21.218: PNNI: Failed To Find An On-Demand Route, Code: PNNI_RESOURCE_UNAVAILABLE *Apr 10 23:11:21.218: PNNI: No Route To 88:160:xx.348F8001BBFC00000BA06F10.408021810A00.00 *Apr 10 23:11:21.218: PNNI: Send Source Route Reply To Requestor: Code PNNI_RESOURCE_UNAVAILABLE ---

When the call is initiated from the LightSteam 1010 switch, nothing comes to the Alcatel switch. At the same time, when the call is initiated from the Alcatel switch, the Soft PVC comes up:

Switch# show atm vc interface atm 9/1/1 Interface VPI VCI Type X-Interface X-VPI X-VCI Encap Status ATM9/1/1 0 5 PVC ATM13/0/0 0 72 QSAAL UP ATM9/1/1 0 16 PVC ATM13/0/0 0 40 ILMI UP >>Alcatel Init <<<< ATM9/1/1 0 400 SoftVC ATM12/0/3 0 227 UP >> LS1010 Init <<<< ATM9/1/1 1 455 SoftVC NOT CONNECTED

Workaround: None.

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 ATM switches or Catalyst 8510 MSR 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.

CSCea48476

Symptom: POD (Parallel Optical Device) fails with ATMDIAG_UNEXPECTED_PIF_INTERRUPT_ERROR. POD errors might occur in some LightStream 1010 switches. These errors occurred on ports that were up and working. This problem appears to be a false error reported by POD.

Workaround: None.

CSCea33595

Symptom: On a LightStream 1010 switch running Cisco IOS Release 120-24.W5.26b, might crash because of 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 LightStream 1010 ATM switch the following error message appears:

ACL is not supported

ACL functionality on the interface is not affected.

Workaround: None.

CSCea28131

A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. 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. BGP MD5 is a valid workaround for this problem.

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-20040616-bgp.shtml.

CSCdz71298

Symptom: The Catalyst 8510 MSR might display following error messages:

xpif_read_media_type: Null ds structure for Port-channel1 xpif_read_media_type: Null ds structure for Port-channel1

Workaround: None.

CSCdz06963

Symptom: After a LAN emulation client (LEC) goes down, a router that has an enhanced ATM port adapter (PA-A3) may not be able to register a network service access point (NSAP) address with an Integrated Local Management Interface (ILMI). Several messages that are similar to the following may be logged in the log file:


%LANE-3-NOREGILMI: ATM1/1/0.7 LEC cannot register 39.000000000000000000000022.000163728428.07 with ILMI

%LANE-3-NOREGILMI: ATM1/1/0.6 LEC cannot register 39.000000000000000000000022.000163728428.06 with ILMI

This symptom is observed on a Cisco router that has a PA-A3 port adapter and that is running Cisco IOS Release 12.2(10a). This symptom is observed after the software is upgraded from Cisco IOS Release 12.2(8)T4.

Workaround: Reload the router.

CSCdy81424

Symptom: Same problem as DDTS CSCdx58649 · except the fix was not committed to the LightStream 1010 image.

Workaround: None.

CSCdy45231

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

Workaround: None.

CSCdy44850

Symptom: The command network-clock-select priority system disappears from the running configuration after a switch reload.

After entering the command in global configuration mode, the switch parser adds the keyword "clock" at the end of the line and that causes the reload to skip the command when parsing the configuration file.

Workaround: None.

CSCdy38993

Symptom: A Route Processor crash occurs when address registration fails at the switch. Also, an error message is flashed to the console. This problem occurs when traffic is flowing over a Flexwan module and either a hw-module-reset or OIR has occurred.

Workaround: None.

CSCdy32886

Symptom: When using version UNI 4.0, during SVC call set ups, a Catalyst 8500 MSR switch in the "Call Received" state does not send a connect-ack upon reception of a connect. This causes the SVC to be released.

Workaround: Use version UNI 3.1

CSCdy25535

Symptom: On a Catalyst 8500 MSR or LightStream 1010 switch with a DS3 interface, the interface goes down after only 7ms of AIS and then comes back up. For example, the following message appears:

%LINK-5-CHANGED: Interface ATM1/0/0, changed state to going down

Approximately three seconds later, the next message appears:

%LINK-3-UPDOWN: Interface ATM1/0/0, changed state to up

Note This might happen when experiencing a protection switchover on the transport network.


Workaround: None.

CSCdy07314

Symptom: A Catalyst 8500 MSR running Cisco IOS version 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, Catalyst 8510, or LightStream 1010 switch, 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 fail. 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.

CSCdx68903

Symptom: The Catalyst 8510 MSR might encounter a memory leak in ATMSIG processes and this might render the switch unusable after one month of operation.

Workaround: None.

CSCdx65390

Symptom: When a point-to-multipoint SVC connection is set up through a switch (root and leaf are active and cross-connected), and a request is received to add a leaf through another interface, and the allocation of this half-leg fails, the connection structures associated with this half-leg are not cleaned up. This means when the connection is cleared, that failed connection cannot be released.

This ties up bandwidth and VPI and VCI resources for the root half-leg of the connection.


Note These resources cannot be cleared using the shutdown and no shutdown commands on the interface.


Workaround: None.

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 and 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 non-errored messages. This is for "mmc errors" and "atm sig cc-errors".

Workaround: None.

CSCdx49779

Symptom: The switch crashes when the IPX encapsulation is changed on Fast Ethernet or Portchannel interfaces.

This might occur after you change encapsulation and then use the shutdown and no shutdown commands.

Workaround: None.

CSCdx47684

Symptom: On the LightStream 1010 switch, 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.

CSCdx29693

Symptom: An ARM configured with subinterface and PVCs loses IP connectivity over the active PVCs.

Workaround: To delete and reconfigure the PVC configuration restores connectivity.

CSCdx11136

Symptom: Power-on Diagnostics fail on the Catalyst 8510 MSR when Cisco IOS Release 12.1(10)E or higher is loaded in the bootflash.

Workaround: None.

CSCdx09652

Symptom: After OAM detects a failure on a PVC terminating on the ATM Router Module (ARM), it fails to remove the adjacency, the directly connected route, and any additional route pointing to the next hop reachable over the failed PVC. This condition might stop traffic.

Workaround: There is no work-around, other than to perform an admin shutdown of the ARM subinterface (if the PVC is the last or only PVC on that subinterface). Alternatively, you could remove the PVC until the problem has been rectified.

CSCdx06532

Symptom: The PNNI-MIB object pnniLinkIfIndex(.1.3.6.1.4.1.353.5.4.1.1.9.1.11) returns 0 on the main interface running PNNI.

This problem does not exist in 12.0(13)W5(19c) but exists in 12.0(18)W5(22) and 12.0(20)W5(24a).

Workaround: None.

CSCdx04773

Symptom: When the Cisco ATM switch is running UNI 4.0 with a Fore or Marconi switch, it might releasing 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 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 softVC.

Workaround: None.

CSCdw93109

Symptom: When using ATM Frame Relay IWF on a Catalyst 8540 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.

CSCdw90604

Symptom: Interoperability problem between LightStream 1010 and Compaq Server with ATM NIC if you pull out the optical fiber connection and reconnect it. If you do so, ILMI keeps restarting, and never stabilizes. You can use the shutdown command on the interface, then disconnect and reconnect the fiber optic connection and use the no shutdown command on the ATM interface to eliminate the problem. These commands cause ILMI to restart correctly.


Note Using the shutdown and no shutdown commands on the LightStream 1010 ATM interface after the disconnection and reconnection does not solve the problem.


Workaround: Follow these steps:
1. Reboot the server.
2. Use the shutdown and no shutdown commands on the des ATM-Switch-Interfaces.
3. Restart of the ATM-NIC (only the NIC interface).
4. Bind the TCP-Stack.

CSCdw84540

Symptom: LightStream 1010 switches running 12.0(X)W5 Cisco 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 LightStream 1010 ATM interfaces if the point-to-multipoint interoperability issue is observed.

CSCdw79090

Symptom: Occasionally after a system crash or route processor switchover you may see a PVC connection that exists in the interface software configuration but not does appear configured in the interface hardware.

Workaround: Perform an OIR on the interface module with the failed connection or perform a route processor switchover to restore the connection on the interface hardware.

CSCdw70257

Symptom: A Catalyst 8510 MSR configured with an IMA (inverse multiplexing for ATM) bundle might not log link up or down status messages. Only messages displaying clock change are logged. See 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 its revertive clocking and the source is recovered, link functionality is restored. Confusion can be created if there are multiple links flapping and only CLOCKSW messages are received without reporting status of the interface.

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


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


Workaround: None.

CSCdw67033

Symptom: If configuring RFC1483 bridging on the ATM router module, when certain RFC 1483 bridging PVC cable connections are unplugged the Catalyst 8540MSR CPU utilization will become very high. This could last a few hours until you shutdown the corresponding bridge-group subinterface on the ATM router module. Only shutting down the physical ATM port will not help.

Workaround: Shutdown the corresponding bridging group subinterface on ATM router module.

CSCdw65903

Symptom: Multiple Cisco products contain vulnerabilities in the processing of Simple Network Management Protocol (SNMP) messages. The vulnerabilities can be repeatedly exploited to produce a denial of service. In most cases, workarounds are available that may mitigate the impact. These vulnerabilities are identified by various groups as VU#617947, VU#107186, OUSPG #0100, CAN-2002-0012, and CAN-2002-0013.

This advisory is available at http://www.cisco.com/warp/public/707/cisco-malformed-snmp-msgs-pub.shtml.

Workaround: None.

CSCdw55504

Symptom: AIS signal taken into account with 2 seconds delay.

Workaround: None.

CSCdw45551

Symptom: On the LightStream 1010 switch, the following error message appears if your switch is using Cisco IOS Release 12.0(19)W5(23):

Jan 15 12:34:19.734 CET:%ATMSIG-3-FAILXCONN: Xconnect failed, xconn fail -Traceback= 6054D9CC 6054F8A0 60559AF0 60548BC0 60548CC8 6009938C 60099378 Jan 15 12:34:19.738 CET: ATMSIG(0/1/0:0 0,174 - 4887/00): (vcnum:0) XConnected failed To Jan 15 12:34:19.738 CET: ATMSIG(1/0/0:0 0,251 - 93568/00): (vcnum:0) Jan 15 12:34:19.738 CET: ATMSIG: CONNECTION MANAGER/CAC Xconn install request Port A - (0/1/0) : 0 vpi = 0; vci = 174 Port B - (1/0/0) : 0 vpi = 0; vci = 251; new vpi = 0; new vci = 251 existing vpi/vci for leg B Jan 15 12:34:19.738 CET: ATMSIG: CONNECTION MANAGER/CAC Xconn install result CONN_INSTALL_RESULT_HW_FAIL

It appears frequently without any other preceding error messages and software/hardware changes on the switch.

Workaround: Upon its first appearance the issue was avoided by reloading the switch.

CSCdw44534

Symptom: Excessive CLP0 discards on TSCAM for PD enabled VCs.

Workaround: None.

CSCdw43258 (LightStream 1010)

Symptom: If you use the show version command on a LightStream 1010 switch with a faulty Flash PC card, the following error message might appear:

%SYS-3-CPUHOG: Task ran for 3708 msec (343/19), process = Virtual Exec, PC = %600AB140. -Traceback= 600AB148 60038620 60038D1C 60038734 600384D8 60038D1C 60038734 6044C190 6005809C 60057DDC 6004BF74

Workaround: Use a different Flash PC card.

CSCdw41639

Symptom: The LightStream 1010 switch might drop OAM F5 END Loopback cells under its default configuration of OAM intercept (which is enabled by default).

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.

CSCdw39079

Symptom: SSH fails with the CRC-check failed error message sometimes.

Workaround: None.

CSCdw33859

Symptom: If you use the no negotiation auto command in interface config 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.

CSCdw33641

Symptom: The Catalyst 8540MSR and LightStream 1010 console hangs when using the hw-module {slot number | subslot subslot/subcard} reset command on the Frame Relay E1 interface nodule.

Workaround: Shutdown all controllers in the module before using the hw-module {slot number | subslot subslot/subcard} reset command.

CSCdw33267

Symptom: Load balancing between provider edge (PE) to provider (P) switches and provider edge to provider edge does not work. If MPLS is enabled on the switch router running Release 12.1 software, MPLS might not re-resolve all dependant routes for a path if you enter the shut/noshut or the clear ip route commands on the outgoing interface of the next hop router.

Workaround: None.

CSCdw31172

Symptom: Unusual delays in Frame Relay VC counters update on Frame Relay ATM interface modules.

Workaround: None.

CSCdw27518

Symptom: Frame relay PVC goes down and remains down after enabling the OAM feature and performing a shut / no shut on the serial interface. However, traffic flow is not affected through the PVC even though it appears down.

Workaround: Disable OAM and shut/no shut the serial interface to force the interface to appear back up.

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.

CSCdw23597

Symptom: Globally changing TDP to LDP or changing LDP to TDP sometimes causes a loss of neighbors.

Workaround: Following is a four-step work-around:

1. Configure no tag-switching ip on both sides.

2. Configure the desired protocol at each end.

3. Wait two minutes.

4. Configure tag-switching ip at each end.

CSCdw22219

Symptom: If PNNI continuously receives a high rate of corrupted PTSP packets over a long period of time, it can cause a large number of internal node numbers to be generated for bogus Node IDs. If the number of internal node numbers reaches 1032, it can cause a crash.

Under normal conditions, PTSP packets should have a very low rate of being corrupted. But if PNNI interfaces are tunneled through a network where the connections are rate limited to a too low rate it can force cell drops which can corrupt packets.

Workaround: Troubleshoot and remove the cause of PTSP packet corruption.

CSCdw22042

Symptom: A point-to-multi point failure might occur if a physical hardware connection does not exist but a virtual software connection is configured. Due to the connection delink failure the following error message appears on the console:

%ATMCORE-3-INTERNAL_ERROR: connDeLinkP2mpPeerLegs: wrong root FSM

Workaround: None.

CSCdw14139

Symptom: The combined installation of TSCAM and a mixed interface module might cause the following mmc_queuecell failure message to appear:

"%AAL5-3-INTERNAL_ERROR: aal5send: mmc_queuecell failed "

Workaround: None.

CSCdw11289

Symptom: The ATM router module has only 147 Mbps of resources available on the ATM interfaces. The following display shows the available bit rate for an ATM router module ATM interface:

Switch# show atm interface resource atm 0/1/1    [Information Deleted] Resource Management state: Available bit rates (in Kbps): 147743 cbr RX, 147743 cbr TX, 147743 vbr RX, 147743 vbr TX, 147743 abr RX, 147743 abr TX, 147743 ubr RX, 147743 ubr TX Allocated bit rates: 0 cbr RX, 0 cbr TX, 0 vbr RX, 0 vbr TX, 0 abr RX, 0 abr TX, 0 ubr RX, 0 ubr TX Best effort connections: 0 pvcs, 0 svcs

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.

CSCdw09750

Symptom: Inverse ARP does not succeed for a Frame Relay PVC terminated on ATM router module.

Workaround: None.

CSCdw04573

Symptom: The enhanced ATM router module subinterface counters do not get updated.

Workaround: None.

CSCdw02689

Symptom: When reloading the switch the following error message appears after a varying number of SVCs are set up.

00:20:42: %ATMCORE-3-INTERNAL_ERROR: atmCore_connCheckSpot: exhausted vpi/vci

Workaround: None

CSCdw01726

Symptom: A Simple Network Management Protocol version 3 (SNMPv3) user is created by using message digest 5 (MD5) authentication with the following commands:

snmp group groupy v3 auth

snmp user abcdefghij groupy v3 auth md5 abcdefghij

An SNMP walk is performed, the configuration is saved, and the switch is reloaded.

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l AuthNoPriv 194.12.224.11

It is working and a debug snmp header shows this:

Incoming SNMP packet : v3 packet security model: v3 security level: auth username: abcdefghij

A second SNMP walk is performed:

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l AuthNoPriv 194.12.224.11

After the second SNMP walk is performed, the command does not return any output and the debug snmp headers show this:

Incoming SNMP packet : v3 packet security model: v3 security level: noauth : username: abcdefghij

Workaround: None.

CSCdv88029

Symptom: PNNI and SSCOP signaling does not come back up on the Catalyst 8540 MSR OC48 interfaces after a power loss and restart.

Workaround: None.

CSCdv87337

Symptom: Ping fails when one of the two parallel soft VCs is missing.

Workaround: Use clear bridge command to reset bridge forwarding cache.

CSCdv85162

Symptom: LDP session does not go down when you shut the enhanced ATM router module interface. When tag-switching is configured on a Fast Ethernet interface and the controlling ATM router module is either not configured or shutdown, TDP will come up but the tag packets received on the Fast Ethernet interface will be dropped because there is no controlling ATM router module to process the packets.

Workaround: Make sure the Fast Ethernet interface is linked to an active controlling ATM router module.

CSCdv82794

Symptom: An ATM router module interface with a PVC configured might experience a port stuck condition.

Workaround: None.

CSCdv67501

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

%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.

CSCdv65055

Symptom: Configuring different encapsulations on 2-port Gigabit Ethernet subinterfaces clears the existing active configuration when multiple subinterfaces are present on a main interface.

Workaround: All subinterfaces have to be configured with the same encapsulation (either 802.1 Q or Inter-Switch Link [ISL]).

CSCdv62465

Symptom: A tag switching traceback might appear when an interface is shut.

Workaround: None.

CSCdv60858

Symptom: A crash occurs while configuring BVI/eigrp, or while powering off the redundant power supply.

Workaround: None.

CSCdv56244

Symptom: Catalyst 8540 CSR eight port Gigabit Ethernet interface modules fails to run CLNS.

Workaround: Update to Cisco IOS release 12.1(11b)E.

CSCdv55117

Symptom: A Catalyst 8540 MSR locks up when configuring ATM port snooping. The switch lockup can occur if ATM port snooping is configured without an analyzer connected to the snoop port.

Workaround: 1.- Load the most recent version of Cisco IOS.

or

2.- Have the analyzer connected to the snoop port prior to configuring ATM port snooping. Keep the analyzer connected until the snoop configuration is removed.

CSCdv49358

Symptom: When a circuit emulation service (CES) circuit that is carrying traffic is removed, no warning message is 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 Cisco IOS version, and tunnels and SVC/Soft VCs are used.

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

CSCdv46664

Symptom: All MPLS VPN connectivity is broken on Cisco 7500, Cisco 7200, and all common platforms if there is a TCATM link between the two provider edges (PEs) that falls in the IGP path and LSP. The routers are disabled from initiating headend VC request over TCATM link.

Workaround: None.

CSCdv45286

Symptom: Point-to-multipoint PVCs that are configured by using SNMP are not preserved across route processor switchovers.

Workaround: Disable the dynamic synchronization feature.

CSCdv43426

Symptom: When a Catalyst 8540 MSR 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.

CSCdv39328

Symptom: When using a Packet Over SONET card, the Open Shortest Path First (OSPF) routes do not come up after a route processor switchover, even though they were up before the switchover.

Workaround: None

CSCdv35065

Symptom: PNNI goes to down state on all interfaces, and all adjacency is lost.

Workaround: None.

CSCdv32093

Symptom: The switch might reload when VP tunnels are created and removed.

Workaround: None.

CSCdv22476

Symptom: The Soft-VC permanent virtual connection (PVC) status is indicated as 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, and the destination end of the Soft VC does not exist, and therefore indicates the PVC status as 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.

CSCdv15294

Symptom: When Frame Relay/ATM Network Interworking (FRF.5) is configured on a Catalyst 8540, traffic above the peak information rate is dropped, and the INPUT ERROR counter is incremented, rather than the INPUT DROPS counter.

Workaround: None.

CSCdv15245

Symptom: With a Frame Relay-ATM Soft-VC set up in FRF5, UPC on the passive side is always set to PASS, regardless of the hard setting on the serial interface with 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 the show vc int serial command always shows the UPC intent as PASS.

Workaround: None.

CSCdv15238

Symptom: Cisco Discovery Protocol (CDP) does not work over Portchannel platforms.

Workaround: None.

CSCdv13291

Symptom: After the simultaneous rebooting of switches terminating the active and passive side of Soft-VC for FRF5, randomly Soft-VPC stays up but, traffic might be dropped on the Frame Relay interface module. This might occur either on the active side of Soft-PVC or on the passive side of the call.

Workaround:

The Frame Relay interface module starts forwarding traffic only after you use the shutdown and no shutdown commands on the serial interface.

You might see the following error message when you reset the Frame Relay interface module:

Error Message: Channel-Group 1 State Change on FR-PAM failed 1

For additional details, refer to DDTS CSCdv17817.

CSCdv11518

Symptom: After the Tag Distribution Protocol (TDP) toggles from down to up ("flaps") on the Label Controlled ATM (LC-ATM) interface, it takes a long time for the interface to become TDP ready. Entering the show tag-switching tdp discovery command might indicate that TDP is not ready, and TVCs might still be allocated on the interface. This can occur under stressful conditions in which cross-connections fail to be de-allocated on the ATM switching fabric.

Workaround: None.

CSCdv11126

Symptom: Single bit errors have been observed on CES circuits originating on the same interface module if two other circuits always carry non-spec-conform AAL1 SNP for SN=0. Only this very high number of SNP errors in 1/8 of all AAL1 cells causes the issue. Multiple SNP corrections that could be seen in production networks are handled correctly without data-loss or corruption.

This is an interoperability issue with a Lucent PSAX 2300.

Workaround: None.

CSCdv07613

Symptom: Under stressful conditions such as large topology changes, TVC cross-connections might fail to be removed from the ATM switching fabric, causing the TC-ATM function to repeat attempts to remove the TVCs. This might lead to the TC-ATM state process entering a bad state, and to an error message being displayed.

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 Simple Network Management Protocol (SNMP) get operations.

Workaround: None.

CSCdv00784

Symptom: The Catalyst 8540 MSR switch may ignore certain commands from the NVRAM after a reboot. This appears most often on switches with dual route processors.

Workaround: Create a connection traffic index and use that number for the set up of the PVC.

CSCdu86398

Symptom: What is present in the Patricia trie in the Ethernet processor interface is out of synchronization with what is present in IP Cisco Express Forwarding (CEF). This might cause connectivity problems. This problem only exists on Ethernet processor interfaces; entries in the Switching Database Manager (SDM) on Gigabit processor interface cards are not affected.

Workaround: Find the route (for example, the route network_x) that is not consistent with IP CEF; enter (in the case of this example) the clear ip route network_x command.

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.

CSCdu78141

Symptom: If a large frame or packet (more than 6096 Bytes) is received on the tag control virtual circuit (0/32 of an interface enabled for tag switching), the frame is not purged from the switch fabric. Subsequent packets received on this virtual circuit are dropped, causing the Tag Distribution Protocol (TDP) and the routing session (OSPF) to time out.

Workaround: Disable, then re-enable, tag switching on the affected interface; subsequent occurrences can be avoided by increasing the queue depth, using the following entry:

atm threshold 2 max-queue-limit 511

CSCdu78056

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

Workaround: None.

CSCdu74491

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

Jul 14 05:00:09: %ATMSIG-3-FAILXCONN: Xconnect failed, xconn fail -Traceback= 6054A204 6054C0A0 60556188 60545538 6054561C 6009930C 600992F8 Queued messages: Jul 14 05:00:09: %SYS-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.

Workaround: None.

CSCdu69809

Symptom: A port of a 4-port DS3 port adapter for LightStream 1010s and for Catalyst 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.

CSCdu65431

Symptom: If the ASP or 8515MSRP installed in a Catalyst 5500 chassis is OIR removed an installed OC12 Single Mode Intermediate Reach module (WAI-OC12-1SS=) continues to send carrier on the OC-12 interface. This causes the interface of the ATM device connected to this interface to display an up/up state even though the interface is reporting constant errors.

This affects all Cisco IOS versions for the Catalyst 8510 MSR and LightStream 1010.


Note The WAI-OC12-1SSLR= and WAI-OC12-1MM= modules do not exhibit this problem.


Workaround: None.

CSCdu57077

Symptom: In a network running cell-mode MPLS (tag switching) with a large number of IP routes (and consequently, with many TVCs being set up), a 16-port OC-3 interface module might fail to allocate a new TVC on a bind request and print out the below error message. This occurs even though the number of TVCs currently set up does not reach the limit of VCs supported on that interface or the cross-connect interface.

Jun 22 20:49:02.011: %TCATM-4-RESOURCE_LIMIT: VC resource exhausted on ATMx/y/z


Workaround: Enter the shutdown command followed by the no shutdown command on the interface for which the error message appears.

CSCdu56774

Symptom: In Cisco IOS Release 12.1(6)EY and earlier, only two equal-cost IP paths were supported on Fast Ethenet and Gigabit Ethernet interface modules that were based on an Ethernet processor interface.

Workaround: Upgrade to Cisco IOS Release 12.1(7a)EY; in that release, four-path load balancing for IP is available through use of the epc epif-4-path-lbal command.

CSCdu53656

A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. 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. BGP MD5 is a valid workaround for this problem.

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-20040616-bgp.shtml.

CSCdu50525

Symptom: The EIGRP Summary Routes are not properly populated in the adjacency table when a default route also exists. This affects the Fast Ethernet and ATM router module interfaces, but does not impact the Gigabit Ethernet interfaces.

Workaround: None.

CSCdu44352

Symptom: A Cisco edge services router (ESR) that is running Cisco IOS Release 12.1(2)E1 experiences interoperability problems when an ATM traffic descriptor information element is included in the CONNECT message on a non-negotiated link. Under such conditions, a STATUS message is sent with cause "invalid information element contents (100)" and call will not succeed. This problem is observed when Cisco routers are connected to other vendor switches like FORE, and occurs only when UNI version is 4.0.

Workaround: None.

CSCdu44017

Symptom: After deleting a connection, an immediate request to re-install with the same VPI/VCI results in connection-creation failure messages.

Workaround: Increase the bit map size from 32 to 64, to avoid reuse of the same VPI/VCI immediately after a call is released.

CSCdu39277

Symptom: After performing consecutive OIRs of three traffic-shaping carrier modules (TSCAMs) in a chassis more than 20 times, memory allocation fails. Because the TSCAMs require 2 MB of contiguous memory, this failure might occur on a system with severely fragmented memory.

Workaround: Do not perform a large number of consecutive OIRs on the TSCAM and do not perform an OIR on a module that has a large number of VCs.

CSCdu35462

Symptom: After a reload, the switch router's memory might be corrupted. This occurs after the following error messages are displayed:

TLB (store) exception occurred on ... dcl-dram-excep: A3420019, dcl-memd-excep: 60C10100, dcl-io-excep: 012C1580" TLB (load or instruction fetch) exception occurred on 00/05/03 10:38:16 ... dcl-dram-excep: A3420019, dcl-memd-excep: 60C10100, dcl-io-excep: 012C15", " *** Unknown External Interrupt *** Stacked Cause = 0x0, Stac

Workaround: None.

CSCdu24272

Symptom: When entering the show atm ilmi-status command the switch shows the 0.0.0.0 as a peer IP address even though a loopback address is configured.

Workaround: None.

CSCdu20618

Symptom: One side of a circuit emulation service (CES) E1 port of a LightStream LS1010 switch connection remains consistently in the YELLOW alarm or ALARM INTEGRATION state.

Workaround: None.

CSCdu21174

Symptom: A switch router with an eight-port Gigabit Ethernet interface module might forward duplicate broadcasts when bridging is configured on a trunk.

Workaround: None.

CSCdu03975

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

Workaround: None.

CSCdu01489

A ROMMON configuration might not work properly.

Symptom: A ROMMON configuration might not work properly on a slot after performing an OIR on the interface module in that slot.

Workaround: Reload the switch router.

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.

CSCdt96389

Symptom: After rebooting the switch router, Ethernet interfaces might have invalid MAC addresses, causing connectivity problems over that interface.

Workaround: Enter the shutdown command and then the no shutdown command on the affected Ethernet interfaces.

CSCdt93866

There might be a buffer overflow.

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.

CSCdt91339

Symptom: In the ATM-MIB there is an atmVcCrossConnectTable that allows SNMP to create VC Cross-connects. It is not possible to create multipoint connections. At the time of creating the second entry corresponding to the multipoint connection, SNMP reports the following error:

# ./snmpset -c private lore atmVcCrossConnectRowStatus.8431167.3.0.51.2.0.41 integer 5 atmMIB.atmMIBObjects.atmVcCrossConnectTable.atmVcCrossConnectEntry.atmVcCrossConnectRo wStatus.8431167.3.0.51.2.0.41 : INTEGER: createAndWait # ./snmpset -c private lore atmVcCrossConnectRowStatus.8431167.3.0.51.3.0.55 integer 5 snmpset: Agent reported error with variable #1. .iso.org.dod.internet.mgmt.mib-2.atmMIB.atmMIBObjects.atmVcCrossConnectTable.atmVcCros sConnectEntry.atmVcCrossConnectRowStatus.8431167.3.0.51.3.0.55: SNMP: A general failure occurred on the agent.

Workaround: None.

CSCdt86157

Symptom: The snmp polling of the virtual path mibs atmVplLastChange and atmVplOperstatus results in unavailability of the virtual path. But the polling of the virtual circuit in this virtual path states that it is available.

Workaround: None.

CSCdt83187

Symptom: On the LightStream 1010 switch when you try to use the atm rmon collect interface command you receive the following error:

ATM-RMON Error: Entry not found

Workaround: None.

CSCdt78388

Symptom: The Catalyst 8510 MSR does not auto boot if the first file in the bootflash is not an executable file (for example, the running-configuration or crashinfo files).

Workaround: Delete any non-executable file from the bootflash that appears before the first bootable image.

CSCdt73634

Symptom: If an interface comes up after the system initialization, the scheduler for that interface might not be programmed correctly. Since IMA interfaces comes up after system initialization, IMA interfaces are usually affected by this.

Workaround: Enter the shutdown command on the IMA interface. Take the first link on the IMA interface out of IMA group. Bring that interface up. Shutdown that interface and then make it part of IMA group. Enter the no shutdown command to bring the IMA interface up.

CSCdt71010

Symptom: The ifTable indexes do not match the MIB-II table indexes.

Workaround: None.

CSCdt63813

Symptom: A LightStream 1010 switch router might automatically reload. When you enter the show version command, the switch reports the reason as "System was restarted by error - a Software forced crash". In addition, log error message might say:

"SYS-6-BLKINFO: Corrupted @redzone blk"

Other messages indicating memory corruption might also occur.

Workaround: None.

CSCdt63152

Symptom: HSRP cannot be configured on Cisco IOS Release 12.1(5)EY1 image on the Catalyst 8510 MSR platform.

Workaround: None.

CSCdt62215

Symptom: After resetting a switch or router that is connected to a CES port on a LightStream 1010 or Catalyst 8510, there is connectivity about the physical layer.

Workaround: Enter the shutdown command and then the no shutdown command on the CBR interface of the LightStream 1010 or Catalyst 8510.

CSCdt60582

Symptom: Two adjacent ATM devices (for example, ATM port at Catalyst 8540, ATM NIC, or Cisco 7200 router) had problems performing ILMI negotiation. The result of the ILMI negotiation is VPI/VCI range fails and the following error message appears:

%SYS-2-MALLOCFAIL: Memory allocation of 1650891065 bytes failed from 0x6066352C, pool Processor, alignment 0 -Process= "ILMI Response", ipl= 0, pid= 80 -Traceback= 6009E1F4 6009FCA0 60663534 60661488 6065EF94 6065E934 6009944C 60099438

Workaround: None.

CSCdt53814

Symptom: An ATM router module port configured for transparent bridging and in blocking state may forward certain frames.

Workaround: Ensure that a non-ATM router module port is in blocking state. If this is not feasible, physically shutdown the ATM router module port that is in blocking state.

CSCdt47492

Symptom: ILMI might stay in the "waitdevtype" state after a redundancy failover. This is because on an OC3 port adapter, each of the 4 ports are served by one processor interface. The first port needs to be set for the other three ports to be able to receive. Sometimes this does not occur on a redundancy failover.

Workaround: Bring up port 0, if problem is seen on ports 1-3, port 4, if problem is seen on ports 5-7, port 8, if problem is seen on ports 9-11, and port 12, if problem is seen on ports 14-15. The ports can be brought up by connecting a loopback cable, or by simply using that port.

CSCdt45629

Symptom: When the switch router is under stress because there are greater than 1000 TVCs on a given interface, some TVCs might not get set up successfully and the following error message occurs:

%TCATM-4-RESOURCE_LIMIT: VC resource exhausted


Workaround: Configure less than 1000 TVCs on interfaces.

CSCdt44914

Symptom: The transmit side of a tag-enabled ATM interface may go into the "not TDP ready" state Use the show tag tdp discovery command to verify that it is in the "not TDP ready" state. As a consequence, Tag is inactive on that interface.

Workaround: Enter the shutdown command followed by the no shutdown command. If this does not work, there is no workaround.

CSCdt43218

Symptom: The IP PAT tree becomes programmed incorrectly for 1483 SVC after removing the ATM router module. If an SVC is configured on an ATM router module/Enhanced ATM router module card and the card is OIRed, the adjacency available across the SVC will remain valid in the EPIF/XPIF cam. This results in packets destined to that adjacency to disappear.

Workaround: Before OIRing an ATM router module/Enhanced ATM router module card, remove any subinterfaces that have a SVC configurations, then proceed to do the OIR.

CSCdt40530

Symptom: When access is made to PNNI tables, a memory leak might occur. This only happens when an Network Management System (NMS) is running SNMP on the switch router.

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

CSCdt38604

A peer switch might not learn an IP address through ILMI-status.

Symptom: An IP address might not be learned by peer switch when using ILMI-status.

Workaround: None.

CSCdt24278

Symptom: The ATM router module sets the CLP of all cells to 1 when bridging is configured over a 1483 PVC. This happens for cells being transmitted over the 1483 PVC only.

Workaround: None.

CSCdt21568

Symptom: The ATM router module interface shut downs when entering the epc portstuck-manual-reload command with IP traffic. This only occurs when running the epc portstuck-manual-reload command several times.

Workaround: None.

CSCdt21513

Symptom: Spurious memory access at lss_arm_atm_adjacency_mac is observed after there is a CLI epc portstuck-manual-reload command entered on two ATM router module interfaces, while two Catalyst 8540 MSRs are connected.

This has no functionality impact.

Workaround: None.

CSCdt18467

Symptom: Port stuck messages might not log into the system log.

Workaround: None.

CSCdt17850

Symptom: The outbound ACL fails to filter packets in the subinterface when the static ARP is configured and the ACL is used with it. If a static ARP is configured and the same address is moved from an interface to a subinterface of the same interface, the static ARP entry remains associated with the main interface itself.

Workaround: When the IP address is reconfigured to a subinterface of a main interface, you then need to delete and reconfigure the ARP address.

CSCdt17751

Symptom: The following operations will result in a CPU HOG and a CPU HOG error message:

when a TSCAM is inserted or removed from the chassis

when a Port Adapter Module (PAM) is inserted into or removed from the subcard 0 position of the TSCAM

This will not affect the future operation of the TSCAM.

Workaround: Though this CPU HOG should not have any adverse impact on the network, it is recommended that any online insertion or removal of TSCAMs or Port Adapter Modules in the subcard 0 position of the TSCAM are scheduled appropriately.

CSCdt15978

Telnet might be slow.

Symptom: Telnet responses between two switch routers might be very slow.

Workaround: Replace one switch router with another that can accept ISL-frames less than 94B in size (for instance, the Catalyst 5000).

CSCdt15169

Symptom: After configuring an ipx network between a Catalyst 8540 MSR and a Catalyst 8540 MSR, and a Catalyst 7500, old buffers detected messages being displayed on the Catalyst 8540 MSR. This occurs with an ATM interface and a Fast Ethernet interface. The Encap is 11 (Novell-Ether). This does not impact any functionality.

Workaround: None.

CSCdt13517

Symptom: A LightStream 1010 stops switching some VCs, and log error messages similar to the following example are generated:

Jan 9 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.

CSCdt11569

Symptom: Oversized packets on the Enhanced ATM router module interface are observed when it is a member of a BVI. This console output relates to the oversized packets on the Enhanced ATM router module interface. The following message is displayed:


00:41:36: %TBRIDGE-4-GIANT: Giant received on ATM3/0/1, 1514 exceeds 1500 DA 0100.5e00.0005 SA 0001.4274.ee09 [0x080045C0]

The system recovers from this. The cause of this may be temporary congestion in the switch fabric, leading to the loss of the last cell of the packet.

Workaround: None.

CSCdt10494

Symptom: The ATM router module (8540-ARM-64K) indicates outgoing packets when on an interface that is in an admin down state.

This was observed on Cisco Internetwork Operating System Software IOS (tm) PNNI Software (cat8540m-WP-M), Version 12.0(10)W5(18c). This does not impact the functionality.

Workaround: None.

CSCdt09229

Symptom: The switch router might loose traffic on its LANE or 1483 or 1577 interfaces on ATM router module. Frame interfaces or non-LANE interfaces on ATM router module with configured PVCs should pass traffic without any problems. It doesn't matter if the traffic is going to route processor or not, part of the traffic is lost.

Workaround: The switch router will recover from this state only after an OIR of the module or a reload.

CSCdt05674

Symptom: A switch with a lot of FC-PCQ connections or running a lot of LANE traffic, might display the following message when the interface carrying most of the traffic is shutdown:

../src-4k-ls1010/mmc_dvr.c 2428 PORT DIED: 0/0/0, taking off line

Workaround: None.

CSCdt04810

Symptom: While executing a series of shutdown/no shutdown commands on the ATM router module interface with a large number of CLIP clients (more than 32), the following error message appears on the console:

00:58:16: %SYS-3-MGDTIMER: Uninitialized timer, timer stop, timer = 644B0550. -Process= "ATM ARP INPUT", ipl= 0, pid= 30 -Traceback= 600CE1BC 600CF2A4 60792B0C 60796850 60797744 600BBA64 600BBA50shut

This does not impact functionality. Enter the shutdown command, followed by the no shutdown command to recover.

Workaround: None.

CSCdt01582

Symptom: On Cisco IOS Release 12.0(10)W5(18b), when the module with c8510-ACL is in the Catalyst 5500 chassis, the show hardware command does not show the ACL daughter card.

Workaround: None.

CSCds86520

Symptom: While sending traffic with super CAM (for example, the OC48 combo super CAM or OC12 super CAM) and enabling the online diags, then performing an OIR of the super CAM. If you use shutdown and no shutdown commands on one of the interfaces you might see the following error message:

ALIGN-3-READEXCEPTION messages.

Workaround: None.

CSCds85282

Symptom: In the Cisco IOS release image ls1010-wp-mz.120-13.W5.19, the LS1010 power on diagnostic test causes the IOS not to boot while the ATM router module and Fast Ethernet modules are installed.

Workaround: Upgrade to Cisco IOS release image version ls1010-wp-mz.120-13.W5.19a.

CSCds81263

Symptom: The IP CEF adjacencies are reported as invalid when using the ATM router module configured with LANE clients on the Catalyst 8540 MSR. The router reports an invalid cached adjacency for ip addresses that is not reachable through the LANE interface when running the show ip cef ip address command.

For example:

show ip cef 207.18.18.0 207.18.18.0/24, version 25, cached adjacency to ATM11/0/0.1 0 packets, 0 bytes via 207.18.19.1, ATM11/0/0.1, 0 dependencies next hop 207.18.19.1, ATM11/0/0.1 invalid cached adjacency

With an invalid cache adjacency, all the packets destined to this address will be sent to the route processor for processing.

The CEF adjacency will be invalid until a LANE data direct VC and valid LE-ARP entry are established on the adjacent device. As soon as the data direct VC and LE-ARP entry are established, the adjacency will be reported as valid.

Workaround: None.

CSCds78385

Symptom: When using the Internetwork Packet Exchange (IPX), the output of the traceroute command skips the middle hop when the middle router is a Catalyst 8540/8510 MSR, Catalyst 8540/8510 CSR, or LightStream 1010.

Workaround: None.

CSCds77275

Symptom: On the LightStream 1010 switch, very intermittently, a SVC call could be rejected due to a VPI/VCI collision when established the call is through a PVP tunnel.

Workaround: After you reseat the interface module on which the PVP tunnel is configured, the condition will be cleared for some time.

CSCds69507

Symptom: If the HSRP has been configured on a Catalyst 8500 running an Cisco IOS Release 12.0(10)W5(18c), and the ATM router module is removed and then reinserted, the HSRP configuration is lost.

Workaround: None.

CSCds57646

Symptom: When a ping command is entered from one member of a BVI to the outside, it causes some pings between members of the BVI to timeout.

Workaround: None.

CSCds55768

Symptom: In a multi-vendor environment, if a non-Cisco IMA interface side does not support Test pattern, as specified in Inverse Multiplexing for ATM (IMA) Specification Version 1.1 by the ATM Forum, the Cisco IMA interface status might from up to down continuously.

Workaround: None.

CSCds44008

Symptom: Under certain conditions, the Catalyst 8510 does not have a certain MAC address in the CAM table. This leads to flooding of L2 traffic for a short time, until the MAC addresses are learned.

Workaround: Issue a clear br gr command.

CSCds40925

Symptom: When entering the show atm interface traffic command on an ATM subinterface, the total number of cells that has passed might show as zero. This rate is incorrect.

Workaround: None.

CSCds28912

Symptom: IP traffic is not sent over a PVC if aal5mux 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.

CSCds27586

Symptom: The subinterfaces of an ATM router module (ATM router module or Enhanced ATM router module) may appear to receive the INARP packets even though the main interface is shut down. The upper layer finally discards the packet based on the state of the interface. There is no impact to any functionality.

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 port adapter is inserted in slot 0 subslot 0 of the carrier module, then the hierarchical VP tunnel can be configured.

Workaround: None.

CSCdr86285

Symptom: The output of the EXEC command show atm controllers atm 2/0/0 is incorrect. Interfaces with spurious card/subcard/port IDs are displayed, duplicating valid interface displays.

Workaround: None.

CSCdr79972

Symptom: The ATM router module always signals a fixed value for the PCR if LANE is configured on the ATM router module. The hidden CLI will give a way to signal the user-configured PCR. This will help with ATM traffic shaping/policing by the ATM nodes in between.

Workaround: None.

CSCdr70086

Symptom: The IP adjacencies are not being cleared from the gigabit ethernet card quickly. The sh epc ip-address command was issued on the adjacency, it was found that the entry for the host on vlan2 was still there and took some time to clear. As soon as it did clear, the ping command works again.

Workaround: None.

CSCdr62898

Symptom: Per-VC drop counters are not consistent. This applies only to non-packet discard connections. The inconsistencies are between the three per-VC statistics: total RX cell drops, RX UPC violations, and RX clp0 q full drops. The total of RX UPC violations and RX Clp0 q full drops exceeds the total RX cell drops count. However, the total RX cell drops is accurate.

Workaround: None.

CSCdr59877

Symptom: In the LightStream 1010 switch, on the output of a show ethernet command display, the "lost carrier" count will follow the collision counter. This is a counter error only and does not actually indicate a lost carrier and does not impact the operation of the Ethernet interface.

Workaround: None.

CSCdr43326

Symptom: The atmVcCrossConnectAdminStatus entries might disappear.

Workaround: None.

CSCdr39274

Symptom: On the LightStream 1010 switch, while trying to monitor ciscoLS1010ModuleOperstatus and while performing snmpwalk on CiscoLS1010ModuleEntry (1.3.6.1.4.1.9.5.11.1.2.1.1) the process goes all the way to 1.3.6.1.4.1.9.5.11.1.2.1.8, which is ciscoLS1010ModuleAdminStatus (which is the second to last field in this table, stops, and does not go all the way to ciscoLS1010Operstatus (1.3.6.1.4.1.9.5.11.1.2.1.1.9).

The ciscoLS1010ModuleOperStatus different status numbers are as follows:

unknown(1)

ok(2)

fault(3)

fanAlarm(4)

partialFault(5)

empty(6)

These status numbers should display "2," which is correct.

Workaround: None.

CSCdr36952

Symptom: The switch router will crash and hang when ip http server 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 by both 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: ifOutOctets wrapping at 3000000 on an ATM interface.

Workaround: None.

CSCdr32958

Symptom: CPU hog by OIR handler.

Workaround: None.

CSCdr30421

Symptom: Multicast stats shows an incorrect rate in kbps.

Workaround: None.

CSCdr28797

Symptom: HVPT: Incorrect scheduling values installed for low PCR. When a HVPT with a PCR of 2 kbps is configured on a OC-3 interface, this results in the cell starving of WKVC on the main interface.

Workaround: None.

CSCdr16095

Symptom: On rare occasions the switch fails SVC set ups even when physical connectivity is established.

Workaround: Reload the switch.

CSCdr02365

Symptom: The output from the show bridge command is incomplete.

Workaround: None.

CSCdr01726

Symptom: The ILMI status of shaped and hierarchical tunnel subinterfaces that are down (not shutdown) appear stuck in the Restarting state after a shutdown/no shutdown command sequence.

Workaround: None.

CSCdp95194

Symptom: A LightStream 1010 configured for MPLS might not correctly increment counters on outgoing TVCs, although the data is being correctly sent out of the TVC.

Workaround: None.

CSCdp80826

Symptom: OAM F5 loopback cells are not passing across 25-Mbps port adapter interfaces.

Workaround: Configure the global configuration command no atm oam intercept end-to-end on the switch.

CSCdp79109

Symptom: The switch might have spurious memory access tags after configuring and unconfiguring tag switching on different ATM interfaces. This is not known to impact tag switching functionality on the switch. The following message might appear on the console:

*** gd03_tag_stress: Mon Jan 31 08:35:12 2000 949336512 comment Spurious memory accesses on gd03_r55_11: count = 1 *** *** gd03_tag_stress: Mon Jan 31 08:35:12 2000 949336512 comment 1C 1 0x60254C28 0x60236140 0x6009868C 0x60098678

Workaround: None.

CSCdp50167

Symptom: IMA group fails to come up intermittently, especially after reload and on E1 IMA links.

Workaround: Go to one of the IMA interfaces and give the following command:

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

If the group still remains down, it indicates a persisting alarm on the line. The line configuration has to be checked to clear the problem.

CSCdp20865

Symptom: Performing a shutdown/no shutdown command sequence on an ATM router module interface, especially when it has configured a large number of LANE clients, might cause an error message like this to appear:

%LANE-3-LANE_ERROR: lecs finder: ILMI hung on interface ATM1/0/0

It indicates an internal timeout occurred. It should try to self-cover and not affect any normal operations.

Workaround: None.

CSCdp15454

Symptom: The PNNI on-demand routing algorithm ignores longer equal cost paths.

Workaround: None.

CSCdp02816

Symptom: The show ncdp path root command might not display any information when you access the switch through the Ethernet port.

Workaround: Access the switch using the console port.

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.

CSCdm36800

Symptom: The CES ABCD bits are not user configurable when a fault occurs.

Workaround: None.

CSCdm62514

Symptom: Reset button does not work correctly, and switch does not reload.

Workaround: None.

CSCdm36284

Symptom: The command show atm resources displays the number of cells in the UBR queue in an MSC and it increases continuously. The increase happens very slowly.

This occurs when traffic is sent through a Catalyst 8540 MSR at line rate. Increasing the threshold group per VC queue size does not eliminate the problem.

Workaround: None.

CSCdm04186

Symptom: EIGRP routes stop might be advertised out of an interface when there doesn't appear to be any interface problems.

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

CSCdk88174

Symptom: The 25-Mbps ATM interface module installed in a LightStream 1010 ATM switch always displays an input rate of 25 Mbps, even if the connected ATM end-station is not sending any data.

Workaround: None.

CSCdk73733

Symptom: Power-on diagnostics will display an NVRAM-Config failure following the second power-cycle after you use the write erase command if the write memory command has not been used between power-cycles.

This failure will occur only if you use the write erase command and the power-on diagnostics runs twice without the write memory command being used.


Note Power-on diagnostics run only if the switch is powered on. Power-on diagnostics do not run when using the reload command.


Workaround: After using the write erase command, use the write memory command before power cycling the switch.

CSCdk64928

Symptom: When a LightStream 1010 ATM switch has its image saved in bootflash and the config-register is configured to 0x2101, the system stays in ROMMON mode after a crash.

If the config-register is set to 0x2102, the switch crashes a second time by bus error while trying to open slot 0. The switch then recovers and boots the bootflash image.

Workaround: Set the MONRC command in the ROM monitor, which overrides any BOOT SYSTEM command from the configuration, as follows:

rommon 1>MONRC="boot bootflash:" rommon 2>sync rommon 3>reset

CSCdk57536

Symptom: The following message appears on the neighbor ATM switch after using the reload command:

%SYS-3-CPUHOG: Task ran for 3984 msec (24/11), process = Net Background

Workaround: None.

CSCdk56557

Symptom: Spurious memory access on show ip route command when SONICT interface is shutdown.

If you shutdown a 10-Mbps port and then use the show ip route command, spurious memory access appears in the print_route_preamble():

Workaround: None.

CSCdk52436

Symptom: On a switch router configured with 32 MB 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 system configured with 64MB of RAM.

Workaround: None.

CSCdk47516

Symptom: Tag switching and Tag Discovery Protocol (TDP) 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 for a very long period of time (for example, overnight) causes memory fragmentation in the TDP process.

Workaround: None.

CSCdk42052

Symptom: When loading a software image version 11.3 or later on a switch router with a software image version 11.2 or earlier, LEC 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.

The ATM address of the switch 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 ATM address with various selector byte values.

Workaround: If LANE components fail to come up because their ATM addresses conflict 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 eliminates this problem.

CSCdk41001

Symptom: The show controller atm card/subcard/port command displays the incorrect interface type after hot swapping the port adapter.

Workaround: None.

CSCdk34773

Symptom: When you try to connect Racal-Datacomm CSUs together using ports on the same CES interface module, timing problems might prevent the CSUs from starting up.

Workaround: None.

CSCdk25256

Symptom: A non-zero generic flow control (GFC) field is not reset to zero when passing through the switch router.

When cells with a non-zero GFC field are received on a PVC, they are switched on the exit port without changing the GFC field. The switch should reset to zero all GFC bits from cells received with non-zero GFC at the user network interface (UNI).

Workaround: None.

CSCdk10398

Symptom: ILMI does not come up upon reload of VP-MUX (VUNI).

ILMI on the tunnel interface, which is connected to the far end peer device through a VP-MUX switch and virtual UNI, is occasionally unable to come up and stay in state of "WaitDevType" after reloading the VP-MUX switch. This situation can be cleared by shutting down the tunnel interface, disabling ILMI followed by a no shutdown command on the tunnel interface. After the interface settles down, ILMI on the tunnel can then be reenabled by shutting down the interface, entering the atm ilmi-enable command and also the atm auto-configuration command, if desired. Reenable the tunnel interface with a no shutdown command.

Workaround: None.

CSCdk07378

Symptom: Funnel VCs can jeopardize quality of service (QoS) for 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 SVC simultaneously, the rate scheduler on the output interface oversubscribes and, potentially, affects the peak cell rate (PCR), sustained cell rate (SCR), and maximum cell rate (MCR) guarantees for other VCs on the interface.

Workaround: None.

CSCdj85853

Symptom: When you set the ROM monitor environment variable boot to a nonexistent file (using the Cisco IOS command boot system flash) and the configuration register is set to 0x2102 (autoboot), the switch hangs during the subsequent reload command issued by the software.

Workaround: Power-cycle the switch; a break character is sent to the switch to force it to the ROM monitor prompt. You can then manually reboot the switch.

CSCdj84379

Symptom: The granularity provided by the FC-PFQ feature card 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. It might be better to do any dropping prior to multiplexing onto the VP, so that a packet discard can be performed. Packet discard cannot be performed on the VP trunk.

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 get switched to other interfaces if a tunnel carrying the TVCs is shut down.

Workaround: Enter a clear ip route command on the switch on the interface that was shut, or a clear ip route command on all the switches 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 that had the closed physical interface.

CSCdj80396

Symptom: While setting up a large number of calls, the system generates the following error message:

%SYS-3-CPUHOG: Task ran for 5852 msec (0/0), process = Exec, PC = 6008DBB4

Workaround: None.

CSCdj78305

Symptom: IP host-routing does not disable when specified.

Workaround: Enable and disable IP routing and then save the configuration to NVRAM.

CSCdj71109

Symptom: The ATM switch does not currently support maxvc-number negotiation through ILMI.

Workaround: None.

CSCdj68412

Symptom: If there are multiple parallel paths to the same destination on a switch router with a FC-PFQ 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 4 parallel paths) instead of being VC merged. Load balancing does not happen in some cases and the TVCs might be VC merge and go out of the switch as a single VC.

Workaround: None.

CSCdj54954

Symptom: On a switch router equipped with an FC-PFQ, the maximum number of cells available for use is 64,511. The number of cells in the switch fabric is 65,535.

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.

CSCdj25772

Symptom: Cell loss might occur while hot swapping a power supply.

Workaround: None.

CSCdj18678

Symptom: SNMP support of the ciscoAtmIfPhysEntryData table and LED information is not available on the 25-MB port adapter.

Workaround: None.

CSCdj18430

Symptom: The cell count reported on a snooped interface is twice the actual number of cells transmitted.

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 (via PortSelTable) is not possible until the interface's 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 its NNI interfaces because of switch crankback attempts. This might result in a discrepancy between the call attempt counters shown on PortSelectGroups representing the interface on which the call came in and the counters shown on the PortSelectGroups representing the interface over which an attempt was made to forward the call. This problem might occur when a call fails.

Workaround: None.

CSCdj01757

Symptom: When one of the installed power supplies is powered OFF, and you are copying an image to bootflash, a power supply failure message appears.

Workaround: None.

CSCdi92142

Symptom: A LECS, using Cisco IOS Version 11.2(X), expects all LESs to establish an individual control VC to the LECS in order to validate clients.

If different emulated Local Area Networks (ELANs), using Cisco IOS Release 11.1(X), are configured on multiple subinterfaces of the same physical interface, then all LESs multiplex the control messages (which validate 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 an LECS sends the following warning messages to the console stating that an LES of one ELAN is attempting to obtain information about another ELAN:

%LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 'sysa_70k_31_a1.1_LAN' %LANE-4-LECS_WARNING: interface ATM2/0/0: elan 'sysa_70k_31_a1.4_LAN' LES asking for elan 'sysa_70k_31_a1.2_LAN' %LANE-4-LECS_WARNING: interface ATM2/0/0: 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 messages.

Workaround: None.

CSCdi83275

Symptom: When a large number of LANE clients come up and down constantly over extended periods of time, the system can run out of AAL5 buffers and the following message appears:

%AAL5-3-INTERNAL_ERROR: No more big aal5 pkts

In most cases, the system continues to function normally, but occasionally the system denies additional calls from end systems.

Workaround: Toggle the interface to reinitialize all connections and restore normal operation.

CSCdi82954

Symptom: The receiver circuitry on DS3 port adapters can interpret noise as a valid signal. This signal is framed incorrectly and does not contain real data. The DS3 controller interprets the signal as a bad signal instead of no signal, and the red RX LED lights up.

Workaround: None.

CSCdi75584

Symptom: Under very heavy traffic conditions the switch might experience temporary queue cell failures. This should clear after the traffic congestion clears.

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.

Workaround: None.

CSCdi55937

Symptom: Remote defect identification (RDI) cells sent by an end point in response to alarm indication signal (AIS) cells generated at an intermediate switch with a fault condition on an interface are not propagated beyond the intermediate switch. The intermediate switch 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.

Workaround: None.

Interoperability

Starting with Cisco IOS Release 12.0(10)W5(18b) software release, 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.
