Problems with hanging MSFC2

alanbcameron
Level 1
Level 1

I have a Multilayer Switch Feature (WS-F6K-MSFC2) installed in a 6509 chassis.

The MSFC hangs periodically where no traffic traverses the switch and from the supervisor I must issue a reset to the device.

It will recover after a fashion.

It has a redundant 6509 which handles BGP duties as well.

I am not certain if this is related, but after issuing the reset  on the primary switch, I must log on to the

backup switch's router and issue a clear ip bgp * command to resume WAN access.

I thought this was a hardware problem. I am being told though by my hardware support this

maybe more a software problem.

I have not made configuration changes to either of these switches in at least a year.

But in reviewing the supervisor log, I see my MSFC has reset a few time in the past

30 days anyway.

Is this a behavior anyone has observed and if so what was the resolution?

Thanks

Hi

Can you post the "show log" of your MSFC ? Can you also let us know what is the IOS version running on the MSFC ? Did you check the release notes to see if there are any open caveats related to hardware reset ? Is the other SUP working good always ?

Raj

Do you mean the show log or the show logging command?

This is in my show logging command:

Hi Alan

I just went through the release notes, and found the following bug.. might be related to your issue: You can probably update your software to 8.4(4) to solve this issue.. this is more related to flapping of interface counters, which is causing your SUP to reset...

CSCeh84332 Bug Details

Line card reset due to excessive Link changes

Under Certain Circumstances constellation classic cards with certain port asic type
(WS-X6148-45AF, WS-X6348-RJ-45,...) may reset with following Error.
2005 May 06 13:02:24 %SYS-5-MOD_NOSCPPINGRESPONSE:Module 9 not responding...
resetting module
2005 May 06 13:02:24 %SYS-5-MOD_RESET:Module 9 reset from Software
2005 May 06 13:04:07 %SYS-5-MOD_OK:Module 9(WS-X6148-45AF,SAL08175TMG) is online

This reset is not because of BAD hardware and is caused if some port/ports
on the particular Line
card are flapping abnormally with high rate.

Work Around:

Check the linkChange counter in the out put of Sh counters.
If this has huge number of link changes then it could cause line card to get
reset.
Fixing the frequent Link change issue will avoid reset of line card.

Also new software will have the fix where system will not reset the line card
if their is rapid
link changes


Hope this helps.. all the best..

Raj

Hello Alan,

Looking at the "sh ver" command you provided, your switch is experiencing software crashes

Identify a Software-forced Crash

A software-forced crash occurs when the router detects a severe, unrecoverable error, and reloads itself so that it does not transmit corrupted data. A vast majority of software-forced crashes are caused by Cisco IOS® software bugs, although some platforms (such as the old Cisco 4000) can report a hardware problem as a software-forced crash.

You should open a TAC case and send them crash file to be analyzed.

Thanks for your prompt and helpful insights.

I will pursue this path of resolution.

Hello Alan

as told in my previous post, you might want to look at the bug that I sent to you.. Have a look at that and see if it matches your issue.. you might then need to upgrade the OS to 8.4(4) to solve this..

Raj

Hi Raj,

He is running native IOS.

Cheers,

Reza
