Hi all,
I have a 2 Cisco 3750X stacked working as CORE switches but not in production yet showing a high CPU utilization and I would like to see with you whether you think this is normal or a IOS upgrade/downgrade should be performed.
I have very low traffic coming through as this is not yet in production:

It is a 48port switch but I am only using 10 ports.
It is configured with few ip prefix list and 3 route-maps but not a heavy config.
Any recommendation?
Thanks
