Hi everyone,
I'm having trouble finding any information on what these logs could mean:

Would this cause any issues?? Downtime, performance?
I have 2 Nexus 5000s configured in VPC, and Po 3 and Po 4 connect to an ESX host (VMWare). These logs are showing up on pretty much all my switches that have the same configuration. Po3 & 4 are configured as edge trunk ports... See config below. Port 4 is configured the same way.
Ethernet1/3 on Switch 1 is configured as a port channel (VPC) with E1/3 on Switch 2. Same thing for E1/4 on Switch 1 in a VPC with E1/4 on Switch 2.
All these ports go to 1 ESX host with 4 CNA ports.

Any ideas what could be causing these logs?
Thanks for the help.
