I am troubleshooting high CPU on a few (5 out of 75) Cisco 3650 (3.07.04E) switches in a flat L2 network. I found that the STP process is floating around 60% on one of the switches.
Is it normal to have all the client interfaces reported in the output of 'show spanning-tree vlan xxx'?
switch#show spanning-tree vlan 200
VLAN0200
