Solved: cisco 3750 stack cpu utilisation

euandrian · ‎02-21-2013

Hi!

i have two cisco 3750 in stack

firts, master switch have all swports busy

second have only 5

how can i see cpu utilizations of the second switch, and its reasonable to move somme devices from first switch to second for

deacreases of cpu and memory utilisations of the master?

the stack tehnologies use both cpu as one? or its only for simple management ?

i realy need an answer now!

googl did nt say this

thanks for help if someone know!

HI Adrian,

Only the Master Switch will do all the processing and not the standby switches.

The CPU doesnt load balance in the stack switches.

Hi Adrian,

Could you please let me know whats the current CPU utlization on the switch?

Also kindly provide me the following outputs:

show version

show proc cpu sorted | ex 0.0

show proc cpu history

show controllers cpu-interface

show platform port-asic stats drop

Hi Adrian,

Currently CPU Utilization is just 7%. When did you see the spike in the cpu?

euandrian · ‎02-21-2013

at the moment its all right, but i have somme hours when its 90%, and somme aplications are very sensible to late response(sorry for my english, can you anderstand?)

Hi Adrian,

Currently everything seems to be okay to me. Usualy high cpu utilization are troubleshooting during the issue to isolate and find the culprit which is causing the cpu to go high.

Regards

Inayath

euandrian · ‎02-21-2013

my main question is if both cpu are used as one or every one is used its own cpu separateley?or there are somthink like """"load balansinc""?

HI Adrian,

Only the Master Switch will do all the processing and not the standby switches.
