Change VMWare ESX/VSphere Host VLAN ID

Recently we had an issue where we had not set the VLAN ID on 10 new VMWare VSphere servers. This resulted in us being unable to manage the VMWare hosts, the only way to resolve this was to change the VLAN ID manually on each of the hosts.

If you find yourself in this situation, you can use the following procedure to change the VLAN ID in VSphere/ESX.

Log on to a VMWare VSphere or ESX host with your ROOT account.

At the prompt enter: esxcfg-vswitch -l
