I have a test ESX 3.5 Virtual server that has two physical NIC's.
I have configured an extra virtual switch so now have two:-
VSwitch0 - Vlan 22 - NIC 0
VSwitch1 - Vlan 122 - NIC 1
Does Vmware automatically connect these switches together in the virtual machine or do I have to do this by connecting them via NIC's, cables and an external switch?
