Processor Memory C2960

DPlagueHT · ‎06-08-2012

Hello

I have a C2960-24PC-L which has a very high occupancy of the processor memory. I've used version 15.0SE 15.0SE2 and now 15.0SE3 and the problem seems to persist.

Is there anything I can do to lower the memory consumption?

Thanks for the help

Green,

can you please show "sh run proc cpu sorted"

I believe that's a cosmetic bug.

capture sh cpu processes and see which interface is utilising the more cpu utilization.

You can check the machjine/server connected to that interface.

1st step try shutting the suspect interafce and check if the process utilzation gets down and works normally....

DPlagueHT · ‎06-11-2012

I put the "sh processes cpu" above.

No interface have relevant traffic at this time, for example, the uplink:

5 minute input rate 80000 bits / sec, 21 packets / sec
5 minute output rate 11000 bits / sec, 8 packets / sec

thanks
