Catalyst 6513 - silent reloads ???

Hi all,

we got 9 catalyst 6513 switches in the access-layer. All switches running the same

Hard/Software constellation (c6k_sup2 engine + cat os 6-3-5 + 12 100BaseFX Boards), absolutely no problems so far.

But now, only one of these access-switches shows unexpected relaods at sporadic intervalls. The NVRAM log shows the reloads but no reasons. After a permanent Console-Logging the following event seems

to be the failure :

int status = 00000400, 00000000mistral interrupt status register contents: 00000

400, 00000000

table manage data par err happened.

mistral interrupt_source_status register contents: 00000400, 20000802

timer 0 int happened.

inband int happened.

programmable int 0 int happened.

table manage data par err happened.

mistral interrupt_status_10 register contents: 00000000, 00000000

fatal mistral happened

The CSCdz65338 Bug Detail discribes a very similar situation, and i realy would like to know what happend there, before updating sw and replace hw ???

Will a sw update truly help or shall i change the complete sup2 ???

What are your experiences ?

THX for your efforts !

Re: Catalyst 6513 - silent reloads ???

Hi Maik,

The first couple of lines seem to sugesting a parity error. This could be as simple as faulty memory on the sup.

However, the bug is very similar to your problem, although it does mention it being an IOS bug and you are running CATos.

I would run the online diags and get the crashinfo file from bootflash (if there is one there) and see if TAC can verify that you have ran into that bug.

Or...you can just upgrade the software anyway and see if it fixes it.

Cheers

Re: Catalyst 6513 - silent reloads ???

Hi Maik,

Looks like you're hitting a mistral interrupt. In 6.3(5), mistral interrupts were not saved to the NVRAM log. I feel that a software upgrade would definitely help here. The 6.3 train continues into the 6.4 train (it's essentially the same train, but due to hw support for a new blade, we had to change the release name for the sake of consistency), and the latest maintenance release of 6.4 will give you all of the diagnostic enhancements and bug fixes that have been integrated into this train. The latest maintenance release of 6.4 is currently 6.4(21) and is GD code.

HTH,

Bobby
