When we check the cpu usage of the switch ,we take this output.

Isn't it high ? What could we do to reduce ?

We have about seventy vlan with HSRP, eighty edge switches with fiber. We dont use BGP protocol, only a few static routes.

Your CPU output seems completely fine.

I suggest the use of the command show proc cpu history, that will show you when spikes happen.

It's OK to have high CPU on a a router, it depends what it's doing.

20% of CPU is completely fine, you should not worry about it.
