Hello everyone - This is my first post so thank you for the help in advance. I have two Cisco CM7x servers running in ESXi with the ESXi server directly connected to a Cisco 3550 switch.
The issue here is that the 3550 is detecting a duplex mismatch with the Cisco CM server. The switch is detecting CM as half duplex, but all configurations (in ESXi and CM) are set for 100/Full. Don't know if this is related, but I read somewhere that spanned CDP traffic from any Cisco device (router, CM, etc.) will show duplex mismatch on the spanned port that's listening on the traffic..?
Has anyone encountered this issue? Again, Cisco CM eth0 is hardcoded for 100/Full, ESXi vmnic is hardcoded for 100/Full, and the switch port is also hardcoded for 100/Full. If this is related to the information I mentioned above, then I'll just go ahead and disable CDP on the connected interface. Thanks again in advance.
