Problem Description

If you are a registered CCO user and you have logged in, you can view details of the defects mentioned in this table.

Background

ROMMON fixes are detailed in the defects listed in the the table above.

The ROMMON images on C8540 route processors (RPs) are designed to be upgraded via the reprogram command. Some RPs were produced with non-AMD chips and the reprogram command can't update them. This can happen on a Catalyst 8540 CSR or MSR RP. This is a hardware problem; it is sensitive to temperature and varies from board to board.

Problem Symptoms

Output from boot with config reg at 2102. The following output doesn't display in the show stack output, but it does in the show crash-info output. Any attempt to boot an image by secondary RP using 0x2102 results in the following crash:

Enter hex value: 0x600B05F8
      0x600B05F8:emt_call(0x600b05f4)+0x4

      0x60093DF8:r4k_process_dispatch(0x60093df8)+0x0
      Enter hex value:

With autoboot, crashdump does not stop ROMMON after the crash:

• With the system configured to autoboot, and the redundancy prepare-for-cpu-removal command is issued, the RP does not stay in ROMMON but proceeds to autoboot again.

• When the ROMMON image on the Primary and Secondary RPs is upgraded simultaneously using the reprogram command, one of the RPs may crash.

• When the switch is booted after a power-cycle, the reload reason in the show version command output does not indicate that the system was booted "from power-on".

• Device hangs on an attempt to reprogram ROMMON.

About 10 percent of the time when attempting to reprogram the ROMMON on a Catalyst 8540, the system hangs after displaying:

Workaround/Solution

Some RPs have non-AMD ROMMON chips which can not be upgraded to newer rommon code via the reprogram command. This can be verified with the reprogram command. If the non-AMD failure occurs have the RP replaced.

The solution for all of these issues except Cisco bug ID CSCdp05103 (registered customers only) is to upgrade the ROMMON image to COUGAR_RM.120-4.6.W5.13.srec.

To download this image, refer to Cisco Catalyst 8540m Software Images (registered customers only) .

The workaround for Cisco bug Id CSCdp05103 (registered customers only) is to reboot the switch. The solution for this issue is to load RP FPGA image version 4.7.
