We have multiple closets at a EDU customer's High School many of which are seeing 90+% CPU spikes on a regular basis. I have read the articles about 8-20% CPU usage and the cli related CPU levels of 30+%.
The customer is experiencing random network issues this for the second day in a row and it is hard to argue against the CPU usage being related. Yes, I understand switching should not be affected by CPU usage.
These are stacks of 3-6 X440-G2-48p.
They are running summitX-184.108.40.206-patch1-7
ELRP is configured
configure elrp-client periodic vlan NOLOOP ports all disable-port duration 600
configure elrp-client disable-port exclude ports 1:52
NOLOOP is on every port on every stack.
