Topology:
Nexus 7710 to FEX. no VPC configuration. Image: 7.2(1)D1(1)
ESX host is not running spanning-tree, port configured as trunk with VLANs.
When I hook an ESX host up to my FEX host port configured as a trunk, the port does not go into err-disable mode, the FEX host port shows up/up but I cannot connect to any of the trunked VLANs either.
Am i missing something? Thanks
Config is as follow:
interface Ethernet8/19
