cpu high on Cat4k

Sir,

My cpu utility on C4k is always high even with any configuration and connection. After I remove a 4232 module, everything is ok. Please help me identity the problem.

Thank you very much!

Regards,

Sha, Haijiang

Re: cpu high on Cat4k

Sir,

Thank you first!

I read the document. I don't think it's normal.

The switchover traiffic are:

Address learning;

STP traffic;

control traffic;

management traffic;

Now there is not any connection and configuration. Except little control traffic, i don't think there are enough traffic would use switching overh process.

And after i remove a 4232 module. The cpu utility would drop.

Thanks again.

Agree, if I am not wrong, the 4232 module is the worst case causing other unexpected system crash when plug-in some multi-mac connection.

Don't any patching or solution from Cisco available.
