I just recently did a clean install of ESX 3.5 on an ESX host at a remote site (the system was on ESX 2.5.3). Unfortunately we did not do any "trunking" with ESX 2.5.3 and had our network people change the ports to trunk except for the Vmotion physical connection. My question is how can I "stop" a vmnic so that the network people can see the verify the port from the switch?
