Problem Description

Cisco C6MSFC 12.1(1)E2 images are being deferred due to the following problem:

After a software upgrade on a Catalyst 6000 with redundant MSFCs to Cisco IOS® Software release 12.1(1)E2, the MSFC modules 15 (supervisor slot 1) and 16 (supervisor slot 2) appear faulty. The MSFC ports also stop trunking.

Background

This problem can be identified by issuing a show module command following upgrade. Here is an example:

MSFCs can still be sessioned into, but have to be reloaded to clear the MSFC faulty state or bring up MSFC port trunking.

Problem Symptoms

This problem will appear after upgrading to MSFC IOS 12.1(1)E2. It is caused by the MSFC booting prior to software boot diagnostics, and can be avoided by introducing a delay in the MSFC's boot sequence.

Workaround/Solution

Workaround

If MSFC IOS release 12.1(1)E2 is required for your Catalyst 6000 you can take the following steps to avoid this problem:

Specify multiple invalid (dummy) images for the MSFC to boot before specifying a valid boot image. A minimum of 3 invalid images that point to "sup-slot0:" need to be specified for this workaround to be effective.

For example:

boot system flash sup-slot0:test <---dummy boot statement

boot system flash sup-slot0:test1 <---dummy boot statement

boot system flash sup-slot0:test2 <---dummy boot statement

boot system flash bootflash:c6msfc-js-mz.121-1.E2 <--- correct boot statement

This sequence will introduce a sufficient delay in the MSFC to allow the the boot sequence with the supervisor to proceed correctly.

Solution

This problem does not appear in Cisco IOS Software release 12.1(1)E and has been fixed in release 12.1(2)E.

Cisco IOS 12.1(1)E2 orders will be converted to 12.1(1)E until 12.1(2)E is available. CCO IOS Upgrade Planner will remove 12.1(1)E2 c6msfc-*-mz images.
