Physical Host Networking Setup:
The physical host was installed with ESXi 4.1 with basic vSwitch networking initially. I elected to configure both physical NIC’s as a LAG’s to simply the physical connectivity due to all of the virtual networking. Below you can see the port groups configured and highlighted is VLAN 4095. This is a key VLAN becuase the “Virtual” ESX VM’s will use this to see all the same VLAN’s as the physical to fully mimic a true VLAN network configuration. If you don’t do this you will have to add multiple NIC’s to each Virtual ESX server to access the port groups. This gets a little confusing so after playing with it I decided to go the 4095 route which works perfectly. Also pictures is the vSwitch security settings. for all the follow on nested ESX virtual machines to work and boot up nested VM’s on them as well as access the networks. This is a key limitation that makes this not well suited for production networks.
