The Catalyst 8540 multiservice switch router (MSR) is a 13-slot, modular chassis featuring dual, fault-tolerant, load-sharing AC or DC power supplies. The ATM switch router provides a 20-Gbps full-duplex nonblocking switch fabric with switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.
The Catalyst 8540 CSR switch router belongs to a class of high-performance Layer 3 switch routers and is optimized for the campus LAN or the intranet. The Catalyst 8540 CSR switch router provides both wirespeed Ethernet routing and switching services.
System Requirements
This section describes the system requirements for Cisco IOS Release 12.0(19)W5(23) and includes the following sections:
Memory Requirements, page 2
Minimum Flash Memory Requirements, page 2
Hardware Supported, page 4
Determining Your Software Release, page 7
Other Firmware Code, page 8
Feature Set Tables, page 8
Release Names, Versions, and Part Numbers, page 24
Memory Requirements
The DRAM memory configuration is 256 MB, which is the default for the Catalyst 8540.
Minimum Flash Memory Requirements
Cisco IOS Release 12.0(19)W5(23) and later releases require a minimum of 16 MB of contiguous boot Flash memory. The Catalyst 8540 route processor now ships by default with a 16-MB boot Flash SIMM.
Earlier releases of the Catalyst 8540 switch router shipped with an 8-MB boot Flash SIMM. The 8-MB boot Flash SIMM is not large enough to store system images for Cisco IOS software releases 12.0(4a)W5(11a) and later.
To check that your system has a 16-MB boot Flash SIMM, enter the show hardware EXEC command. The part numbers for route processors with a default 16-MB boot Flash SIMM are as follows:
73-2644-06 Rev. A0 for the Catalyst 8540 MSR
73-3775-03 Rev. A0 for the Catalyst 8540 CSR
If you have an 8-MB boot Flash SIMM, and have no additional memory installed, we recommend that you order a spare Flash PC card programmed with the latest version of the system image, part number MEM-8540M-FLC20M=.
Alternatively, you can use one of the following options to accommodate the larger image:
Option 1If you already have a Flash PC card, download the system image to the Flash PC card.
Note If you have a Smart Modular, Sharp, or Intel 2+ Flash PC card that was formatted using
a Cisco IOS software release prior to 12.0(4a)W5(11a), reformat it with Cisco IOS
Release 12.0(19)W5(23) prior to downloading the image (you might need to boot the
image from a TFTP server to format the PC Flash card). Do not erase the system image
on the boot Flash SIMM. If the procedure fails, you will need it to recover. (See caveat
CSCdm47012 later in these release notes for more information.)
Then do the following:
Enter the config-register 0x2102 global configuration command to change the configuration register to boot from the Flash PC card, instead of booting from the system-code SIMM (default).
Note If you have a redundant route processor configuration, you need ROMMON image 12.0(4.6)W5(13)
or later. See caveats CSCdm81581, CSCdm54297, and CSCdm43664, which are described later in
these release notes, for more information.
Enter the boot system slot0:filename global configuration command to specify the system image to boot on the Flash PC card.
Enter the copy system:running-config nvram:startup-config privileged EXEC command to save the configuration changes to NVRAM.
An example follows:
Switch(config)# config-register 0x2102
EHSA:Syncing confreg: 256 to secondary
Switch(config)# boot system slot0:cat8540m-wp-mz.120-4a.W5.11a
Switch(config)# end
Switch# copy running-config startup-config
Option 2Download the system image to a TFTP server and boot the system image from the TFTP server. Enter the boot system tftpfilenameip-address global configuration command to boot the system image from the TFTP server, instead of booting from the system-code SIMM (default).
An example follows:
Switch(config)# boot system tftp cat8540m-wp-mz.120-4a.W5.11a172.20.52.3
Note You can boot only the primary route processor from a TFTP server, not the secondary.
Note The boot ROM on the Catalyst 8540 can be field-upgraded via the reprogram command. For more
information about upgrading the boot ROM, see the
ATM Switch Router Command Reference.
For more information about downloading system images and changing the default boot image, refer to the "File Management" chapter of the Configuration Fundamentals Configuration Guide in the Cisco IOS software documentation set.

Determining Your Software Release
To determine the version of Cisco IOS software currently running on the Catalyst 8540, log into the switch and use the show version privileged EXEC command. The following sample output is from the show version command. The version number is indicated on the second line as shown below:
Cisco Internetwork Operating System Software
IOS (tm) PNNI Software (cat8540m-WP-M), Version 12.0(19)W5(23)
Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.
Other Firmware Code
Most of the port adapters and interface modules supported on the Catalyst 8540 have 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:
For information describing the firmware update process, refer to the section "Maintaining Functional Images (Catalyst 8540)" in the chapter "Managing Configuration Files, System Images, and Functional Images" in the ATM Switch Router Software Configuration Guide.
Feature Set Tables
The Cisco IOS Release software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. Table 3 lists the Cisco IOS software feature sets available for the Catalyst 8540 MSR. Table 4 lists the Cisco IOS software feature sets available for theCatalyst 8540 CSR.

Caveat Symptoms and Workarounds
This section contains listings of the caveats for the Cisco IOS software:
With some OC-12c single-mode fiber line modules, the link might fail after inserting the fiber cable. Make sure that the fiber cables are completely seated by pushing on the strain reliefs of the individual fibers until they click into place to complete the optical connection. In some cases, the small metal septum on the front panel of the transceiver obstructs the connection.
The maximum number of ELAN LES/BUS pairs supported is 10.
The Catalyst 8540 does not support Token Ring LANE.
The ATM router module does not support Fast Simple Server Redundancy Protocol (FSSRP).
CSCdm29529
Symptom: On the Catalyst 8540 MSR it is not possible to use a VCI value higher than 8191 for soft VCs and PVCs on the same interface module or port adapter where more than one VCI is configured.
Workaround: Use VCI values lower than 8192.
CSCdm36284
Symptom: The command show atm resources displays the number of cells in the UBR queue in an MSC and it increases continuously. Note, 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.
Symptom: Loopback cells might not pass across the 25-Mbps ATM port adapter modules.
Workaround: Configure the no atm oam intercept end-to-end command from global configuration mode.
CSCdp95194
Symptom: A LightStream 1010 configured for MPLS (tag switching) and running the Cisco IOS 12.0(9) maintenance software release does not correctly increment counters on outgoing TVCs, although the data are being correctly sent out of the TVC.
Workaround: Upgrade to 12.0(4a)W5(11a) or higher.
CSCdr20193
Symptom: The switch router might reload after a bus error in handle_new_collect.
Workaround: None.
CSCdr59347
Symptom: When two Catalyst 8540 CSRs with two-port Gigabit Ethernet interface modules are connected back-to-back, packets are lost. On one side the counters might show input and output increasing, but the other side shows only output packets increasing. The Address Resolution Protocol (ARP) from the other side is lost, and the ability to ping the other side is lost.
Workaround: Reset the GBIC.
CSCds43859
Symptom: Although packets are being sent out from an ATM OC-12 interface module, the 5-minute output rate shown using the sh int atm command indicates 0 bits/sec output. This is not consistent with the output rate shown under the sh atm traffic command.
Workaround: None.
CSCdt05168
Symptom: When using a 155-Mbps port adapter module, the show controller command output will list all port mediums as SM_IR_+.
Workaround: None.
CSCdt05348
Symptom: Cell loss on PVC connections occurs when removing the active route processor.
Workaround: Entering the redundancy prepare-for-cpu-removal command might prevent any cell loss outage from affecting established PVCs.
CSCdt10494
Symptom: An ATM router module interface indicates outgoing packets when that interface is administratively down.
Workaround: None. This does not impact functionality.
CSCdt38728
Symptom: Online Diagnostic might run in the background and then stop suddenly with the following error message:
1d23h: %SCHED-2-EDISMSCRIT: Critical/high priority process Online Diagnostics may not dismiss. -Process= "Online Diags", ipl= 0, pid= 62
Workaround: Enter the diagnostics online snake command in global configuration mode to restart the online diagnostics.
CSCdt46026
Symptom: A switch router with OC3 port adapters and five Fast Ethernet interface modules might boot up with the following error message:
epif_aal5_fastsend: bad vcinfo This message may appear 100s
of times and slow down the boot process. Normal operation does not seem affected
once the 8500 has finished booting.
Workaround: None.
CSCdt49005
Symptom: SVC signalling across a VP tunnel might not work after a reload.
Workaround: None.
CSCdt60582
Symptom: Two adjacent ATM devices (for example, ATM port at Catalyst 8540, ATM NIC, or router) might have trouble performing ILMI negotiation. The failed ILMI negotiation causes VPI/VCI range to fail and the following error message to display:
%SYS-2-MALLOCFAIL: Memory allocation of 1650891065 bytes failed from 0x6066352C,
Symptom: There is a noise problem with the CES PAM hardware version one.
Workaround: None.
CSCdu09850
Symptom: On a Catalyst 8540 performing an ATM-Frame Relay internetworking function, the ATM-Frame Relay does not propagate when the Local Management Interface (LMI) indicates a permanent virtual connection (PVC) as inactive.
Workaround: None.
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 8510MSR and LightStream 1010.
Note The WAI-OC12-1SSLR= and WAI-OC12-1MM= modules do not exhibit this problem.
Workaround: None.
CSCdv05916
Symptom: When an E1 IMA (inverse multiplexing over ATM) adapter is inserted into a chassis in which several other IMA adapters have already been added, the clock cannot be derived from the network.
Workaround: None.
CSCdv08899
Symptom: On the Catalyst 8540 MSR and LightStream 1010 platforms, the option to set loop timing on OC-12 ports is not available.
Workaround: None.
CSCdv22655
Symptom: The following error message does not specify the offending CAM/or port adapter module.:
%OIR-3-LONGSTALL: Long bus stall (20000 s), the new PAM may not seated properly,
Please remove it and try again
Workaround: None.
CSCdv25130
Symptom: A Catalyst 8540 CSR logs the following messages:
%SK-4-WARNING: Slot10: Job ScxMan-pathTable-review ran 10992 (its runTimeMax was 8000)
%SK-4-WARNING: Slot10: Job ScxMan-interruptHandler ran 24378 (its runTimeMax was 20000)
%SK-4-WARNING: Slot10: Internal Warning: Dropped 22 high priority IPC packets
%SK-4-WARNING: Slot10: Internal Warning: Dropped 22 high priority IPC packets
%SK-4-WARNING: Slot10: Internal Warning: Dropped 22 high priority IPC packets
%SK-4-WARNING: Slot10: Internal Warning: Dropped 22 high priority IPC packets
%SK-4-WARNING: Slot10: Internal Warning: Dropped 22 high priority IPC packets
%SK-3-ERROR: Slot10: Have run out of vbufs (internal buffers)
%SK-4-WARNING: Slot10: Internal Warning: Dropped 18 high priority IPC packets
However, no connectivity problem is reported.
Workaround: None.
CSCdv70086
Symptom: A Catalyst 8510 CSR produces Power Supply error messages when writing to the bootflash.
Workaround: None.
CSCdw15274
Symptom: The ARM port appears stuck on a Catalyst 8510 MSR and the ARM interfaces change to Initializing State. Along with the port stuck you might see repeated occurrences of the following error message in the log:
At the same time an output of show controller atm 2/0/0 indicates a large number of cells in memory buffer.
These occurrences are RANDOM and there is no predetermined sequence of events that cause this to happen. It might be traffic related.
The port stuck error occurs due to the large number of cells stuck in the memory buffer causing the CPU to miss the periodic poll of a certain module/interface causing a port stuck message.
Workaround: None.
CSCdw27572
Symptom: A LightStream 1010 might display the following alignment error:
Dec 11 08:04:28.227 MET: %ALIGN-3-CORRECT: Alignment correction made at 0x60329860 reading 0x614202C1
Workaround: None.
Restrictions
This section describes the following Catalyst 8500 MSR restrictions:
ACL Daughter Card Restrictions
AppleTalk Restrictions
ATM Router Module Restrictions
VLAN Encapsulation Restrictions
EtherChannel Restrictions
Maximum Path Restriction for EIGRP or OSPF
Port Snooping Restrictions
Online Insertion and Removal of Interface Modules Restrictions
The following restrictions apply to the ACL daughter card supported on the Catalyst 8540 MSR:
The 8-port Gigabit Ethernet interface does not support an ACL daughter card.
UDP flooding is disabled on routers with an ACL daughter card.
The following ACLs are not supported with the ACL daughter card:
ACL for GEC, FEC, or BVI
Dynamic ACL
Reflexive ACL
IPX extended ACL
ACL logging
Catalyst 8540 CSR
The following restrictions apply to the ACL daughter card supported on the Catalyst 8540 CSR:
The 8-port Gigabit Ethernet interface does not support an ACL daughter card.
UDP flooding is disabled on routers with an ACL daughter card.
The following ACLs are not supported with the ACL daughter card:
ACL for GEC, FEC, or BVI
Dynamic ACL
Reflexive ACL
IPX extended ACL
ACL logging
AppleTalk Restrictions
We recommend that you evaluate the level of CPU utilization and performance in your switch router before turning on AppleTalk. Unlike IP and IPX, AppleTalk routing and processing in the Catalyst 8540 is accomplished by the switch processor, not the interface module. This means that routing AppleTalk packets consumes more processing time than routing other protocol packets. In a switch with a sustained high CPU utilization, turning on AppleTalk could result in longer convergence times for routing protocols like EIGRP. AppleTalk packet throughput is dependent on the amount of available CPU processing power.
ATM Router Module Restrictions
The Catalyst 8540 MSR ATM router module does not support the following features:
Point-to-point subinterfaces. Only point-to-multipoint subinterfaces are supported.
Tag-edged router functionality
Fast Simple Server Redundancy Protocol (FSSRP)
Bridging for multiplexing device encapsulation
Protocol Independent Multicast (PIM) IP multipoint signalling
PIM nonbroadcast multiaccess (NBMA)
PIM over ATM multipoint signalling
Translation from IP quality of service (QoS) to ATM QoS
Resource Reservation Protocol (RSVP) to ATM SVC
PVC management using ILMI
Access lists for ATM to ATM routing
Half-bridge devices
RFC 1577 SVCs
RFC 1483 MUX encapsulation
Appletalk over 1483 VCs
VLAN Encapsulation Restrictions
The four adjacent ports (such as 0-3 or 4-7) on a 10/100 Fast Ethernet interface must all use the same VLAN encapsulation, that is, either 802.1Q and native, or ISL and native.
EtherChannel Restrictions
When assigning Ethernet interfaces to an EtherChannel, all interfaces must be either Fast Ethernet or Gigabit Ethernet. You cannot mix Fast Ethernet and Gigabit Ethernet interfaces within a single EtherChannel.
Maximum Path Restriction for EIGRP or OSPF
Catalyst 8540 interface modules support a maximum of 2 paths. To improve EIGRP or OSPF convergence, set the maximum-paths for the router to 2, using the following command:
8540(config)# router eigrp 109
8540(config-router)# maximum-paths 2
Port Snooping Restrictions
The snooping source port and destination port cannot be the same port.
You can only snoop with one source port and one destination port.
Snooping configuration information is not saved in NVRAM.
You cannot snoop a port that is part of a bridge group.
The eight-port Gigabit Ethernet interface module is supported on the Catalyst 8540 CSR only. This section describes limitations of the eight-port Gigabit Ethernet interface module.
Ports Per Bridge Group Restrictions
The eight-port Gigabit Ethernet interface module installed in a Catalyst 8540 CSR can support a maximum of 128 ports per bridge group.
Port Channel Restrictions
If your Catalyst 8540 CSR has an eight-port Gigabit Ethernet interface module, you cannot create a port channel that has some members on that module and others on other modules. All port channel members must reside on the same Gigabit Ethernet interface module.
Also, if your switch router has an eight-port Gigabit Ethernet interface module, port channel IDs 57 to 64 are reserved, and cannot be assigned to other external interfaces. If you assign a port channel ID number greater than 56, the system will respond with the following message:
Port channel with ID > 56 cannot be created.
If you have already assigned port channel IDs 57 to 64, you must reassign them before installing an eight-port Gigabit Ethernet interface module.
If your switch router does not have an eight-port Gigabit Ethernet interface module, you can assign port channel ID numbers up to 64.
Online Insertion and Removal of Interface Modules Restrictions
The following restrictions apply to the online insertion and removal (OIR), also known as hot swapping, of interface modules on the Catalyst 8500 CSR:
Wait at least one minute after removing an interface module before inserting a new one.
While the device is operating, remove only one interface module at a time.
OIR of the eight-port Gigabit Ethernet interface module is supported in Cisco IOS Release 12.0(5)W5.13 and later releases.
Online Diagnostics Restrictions
Online diagnostics, such as access tests, online insertion and removal (OIR) tests, and snake tests, detect and report hardware failures in the Catalyst 8540 during system bootup and operation. The following restrictions apply to the OIR (also known as hot swapping) tests and the snake tests on the Catalyst 8500 CSR:
The OIR tests support all Layer 3 interface modules, with the exception of the ATM uplink interface module and the eight-port Gigabit Ethernet interface module.
The snake test on the Catalyst 8540 CSR is supported on the enhanced Gigabit Ethernet interface module, the ATM uplink with enhanced Gigabit Ethernet interface module, and the Packet-over-SONET uplink with enhanced Gigabit Ethernet interface module. Snake tests are not supported on either the Fast Ethernet interface modules or the Gigabit Ethernet interface modules.
Note Access tests are supported on all Layer 3 interface modules. Refer to the
"Configuring Online
Diagnostics (Catalyst 8540)" section in the
Layer 3 Switching Software and Feature Configuration
Guide for additional information.
FPGA Upgrade Restriction
On an 8540, the reprogram command for upgrading the FPGA on the switch processor requires power cycling the box after completing the FPGA download.
1000BASE-ZX GBIC Restriction
The Catalyst 8540 MSR switch routers support extra long haul (1000BASE-ZX) GBICs as follows:
Catalyst 8540 MSR: A maximum of 12 1000BASE-ZX GBICs per system to comply with FCC Class A emissions (CFR 47 Part 15), or 8 1000BASE-ZX GBICs per system to comply with EN55022 Class B emissions (CISPR22 Class B).
Catalyst 8540 CSR: A maximum of 12 1000BASE-ZX GBICs per system to comply with FCC Class A emissions (CFR 47 Part 15), or 8 1000BASE-ZX GBICs per system to comply with EN55022 Class B emissions (CISPR22 Class B).
Bridge-Group Virtual Interface Restriction
A Bridge-Group Virtual Interface (BVI) is a virtual interface within the campus switch router that acts like a normal routed interface. A BVI does not support bridging, but it actually represents the corresponding bridge group to routed interfaces within the switch router. The interface number is the link between the BVI and the bridge group.
Layer 3 switching software supports the routing of IP and IPX between routed interfaces and bridged interfaces in the same router, in both fast-switching and process-switching paths. BVIs do not support IP multicast routing.
Catalyst 8540 Route Processor and Switch Module Redundancy
The Catalyst 8540 CSR supports the use of redundant route processors and switch modules. The second route processor would be installed in slot 8, and an additional switch module would be installed in slot 6.
Route Processor
There are some precautions that need to be taken before removing a route processor module from a chassis that is powered-up. If a route processor module that is currently running IOS is removed from the chassis in a skewed manner such that the left side of the processor comes out before the right side does, the traffic flowing through the device might stop flowing.
To avoid this, make sure the route processor module that is being removed is currently at the ROM monitor prompt; it is then safe to remove it from the chassis. One way to get the system into ROM monitor from IOS is to issue a reload command. This will work if the system is not configured to auto-boot. If the system is configured to auto-boot, it starts booting IOS again.
Since you need to ensure that a route processor is in ROM monitor before removing it, the redundancy prepare-for-cpu-removal command has been added to take the system to the ROM monitor prompt. Execute this command on the route processor being removed before removing it. Once this command is issued, the route processor will go to the ROM monitor prompt and stay there even if the system is configured to auto-boot. At this point it is safe to remove the route processor from the system.
Switch Modules
If a Catalyst 8540 has three switch modules, then by default the switch modules in slots 5 and 7 come up as active, and the one in slot 6 comes up as the standby. If you wish to change this default, there is a command that lets you select the "preferred" switch module slots. This command is a privileged exec level command with the following format:
Two unique preferred slots must be specified. The range of the slot value is 5 to 7. If one of the preferred slots is not a currently active switch module, you are informed of this and asked if the system should change the active switch modules to the preferred switch modules. If such a switch-over occurs, all the active connections in the system will be reinitialized. If you wish to continue, then the preferred switch modules become active, and the other switch module becomes the standby. This configuration will remain in effect until either one of the active switch modules is removed.
The preferred switch module configuration is preserved across route processor switch-overs. However, the preferred switch modules setting will be lost if the system is power-cycled or if both route processors are reloaded to the ROM monitor.
Autonegotiation (Catalyst 8540 CSR)
Beginning with Cisco IOS Release 12.0(5)W5(13) software, the autonegotiation feature for speed and duplex on 10/100BASE-T Ethernet ports defaults to "on." This means that for each port, the Catalyst 8540 CSR automatically detects the port speed (10 Mbps or 100 Mbps) and duplex of the peer port, if that port also autonegotiates.
To override autonegotiation and set a port to 10 Mbps operation, issue the following command:
(config-if)# speed 10
To set a port to 100 Mbps operation, issue the following command:
(config-if)# speed 100
To set the duplex value for a port to full-duplex, issue the following command:
(config-if)# duplex full
To set the duplex value for a port to half-duplex, issue the following command:
(config-if)# duplex half
Caution If you connect a Catalyst 8540 CSR running Cisco IOS Release 12.0(5)W5(13) software to a switch router running in forced full-duplex mode, you might encounter symptoms such as high collision rate or reduced throughput, as the Catalyst 8540 unsuccessfully tries to autonegotiate with the other device. When autonegotiation fails, the Catalyst 8540 defaults to half-duplex operation, which causes a mismatch between it and the other device. Possible workarounds include forcing the Catalyst 8540 CSR to operate in full-duplex mode or removing the full-duplex command from the other device.
Incompatibility (Catalyst 8540 CSR)
When you connect a Catalyst 8540 CSR to a Catalyst 5000 100BASE-FX MM Ethernet interface module using ISL, ensure that the hardware version on the Catalyst 5000 interface module is 1.3 or higher. You might experience connectivity problems between the Catalyst 8540 CSR and the Catalyst 5000 if the hardware version on the Catalyst 5000 Ethernet interface module is lower than 1.3.
Interoperability
You can use Catalyst 8540 CSR interface modules in a Catalyst 8540 MSR chassis with an MSR route processor and switch modules. Use only CSR (Ethernet) interface modules, and load the CSR software image on the MSR.
Starting with the following software releases, hardware and software functionality interoperability exists between CSR interface modules and MSR interface modules by way of the ATM router module on the MSR chassis running an MSR image:
Cisco IOS Release 12.0(4a)W5(11a) supports interoperability between CSR interface modules and MSR interface modules by way of the ATM router module on the Catalyst 8540 MSR running an MSR image.
Cisco IOS Release 12.0(10)W5(18b) supports interoperability between CSR interface modules and MSR interface modules by way of the ATM router module on the Catalyst 8510 MSR running an MSR image.
Y2K Compliance
The Catalyst 8540 MSR system running Cisco IOS Release 12.0(0.6)W5(1) or later have been certified as Y2K Compliant. For more information, see the following URL: http://www.cisco.com/warp/public/752/2000/.
