Process level in Catalyst 4503E

Hi Guys

I have a Catalyst 4503E switch with a Supervisor II+TS. I have monitoring for several weeks and I see that the process is over 40%:

I have doubts about the behavior. I sent the show process cpu sorted too:

Re: Process level in Catalyst 4503E

Hi,

There is no unusual behaviour from the (show processes cpu sorted) command. Could you please run this command again when the CPU reaches 40 or above 40% and post the output here.

As ageneral note, 40% is not Scary Percentage of CPU utilization, but for checking purposes , you should figure what most consumes your CPU.

Re: Process level in Catalyst 4503E

   As previous poster said that is not high . these switches will show 30% with nothing running on them .  If you worried about it then go thru the high cpu doc.
