Bit of a strange problem setting up a port group on our vSphere environment. I have createdt he port group as normal, assigned a VLAN number and added in the server in question but the server cannot even ping the default gateway of the port group.
I know I have seen this before but for the life of me can't remember what it was. Has anybody else seen this?
All our other port groups are setup and working, we trunk from our vSphere machines to a Cisco core switch which has the correct vlan(s) setup. This problem appears to be a vSphere 'thing'
