2) If it sued 62%(heavy usage) what could be the reason?How to finout??(if it happens just because of loops ,how to find ut loops easily??Do i have to do "show cdp neighour" for each device and find how many connections are there??)

Thanks

Hello,

As per the logs shown, it is clearly visible that CPU process is reaching 60% and there could be multiple reason for high cpu utilization.

In order to troubleshoot high CPU utilization, 'show log' will be your best friend and it will guide you in the right direction.

You can use few commands along with 'show cpu history' to check the current status and cause of high utilization.

show log - It will show buffered logs messages.

show version - To check cisco IOS software version, platform, cpu type and uptime.

show interface stat - It will show number of characters/packets processed by interfaces.

you can refer the below URL for more details:-
