Hi,
In Cisco 3750 facing high CPU utilization for specific period. During this period traffic response times across the switch degrades
Request help to identify the issue and/or steps to identify interface potentially generating traffic
I have attached 'sh proc cpu history' , ' sh ip traffic', 'sh proc cpu sorted' during troubled period . Also attached snapshot of 'sh ver'
Thanks,
vg

Hi Vg,
Can you provide us the outputs of the following commands as well:
- show platform health
- show platform cpu stat
show platform cpu packet statistics
I see the cpu is going high due to Interupts so kindly provide the requested ouputs and we shall see what causing this.
Regards
Inayath.

3750's perforamance can be dependent on using the correct SDM template. You might check your TCAM usage, i.e. "sh platform tcam utilization".
