3 servers are connected to Nexus 5548 (acting as a L2 TOR switch), some are complaining about traffic slowness, so checked cpu utilization was not bad
You can see for 5 min it is 16%, that is good in case of nexus
TOR01# show processes cpu
CPU utilization for five seconds: 11%/0%; one minute: 15%; five minutes: 16%
