Crashinfo Outputs



Does Cisco have a webpage that can diagnose Crashinfo files? I have the following from a 3750 switch within a stack that crashed this morning...

Or is a TAC CAse needed?

That's it?  Nothing else?

Can you please attach the 4 latest crashinfo files.  If there's a crashinfo file that happens to have a large file size, then attach those too.

Thats it. The only other crashfiles have been from last year.

Ity is better to open an SR to have Cisco engineer look at registers of that crashinfo for the root cause.

The tool that you can use for stack analysis is the output intrepreter but I don't think it will be able to analyze this particular crashinfo file:
