Hi folks,
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%

Indeed cpu is high utilize up to 90%
This can slow the traffic to us not traffic pass use tcam
So why traffic is pass to cpu?
One of case is mtu mismatch, check mtu along the path
MHM
