Hi all,

I am seeing latency on VM hosts between two sites on a dedicated 10gb link. When investigating the network I have also discovered errors on one of the connecting core switches and the other sites distrubtion switch which connects to the VM environment.

Does anybody know what these error are related to?

What is the fix/resolution of the errors?

Could they be causing the latency?
