Re: CPU Profiling - Cisco Router

Guru,

Though i don't know much in detail about CPU profiling, i have worked in the past with Cisco TAC wherein they have asked me to configure the same to troubleshoot high CPU utilization

The command necessary are mostly hidden in the Cisco IOS

We first use the following command to get the addresses

show region | incl main:text

Then create a CPU profile

Router(config)#profile 60008AF4 61D5A5C3 4 ...note the values entered depend on platform. sometimes u need to include the 0x in the beginning...

4 at the end is the increment

You can use show command to view the cpu profile

sh profile detail, sh profile terse

U start the profile and then stop it after a while and the output is then submitted to TAC

Router#profile start

Router#sh profile terse

PROF 60008AF4 61D5A5C3 4

PROFSKIP 6000D354

0 0 0 0 0 1 0 0

PROFSKIP 601C2B74

0 0 1481 0 0 0 0 0

...output omitted

Router#profile stop

Router#clear profile
