Adding VLANs to ESX

ESX 3.02

We currently use 1 subnet (VLAN 1) for all our production network traffic to our VMs. I need to add another subnet to our cluster & just wanted to get some confirmation I'm on the right track:

1. on Ethernet switch, change port connected to vmnic0 to allow trunking & add VLAN 2

2. on ESX host, change VLAN ID on vSwitch0 from * to 1.

3. on ESX host, create new vSwitch1 for VLAN ID 2.

4. on ESX host, assign new VMs using new subnet to vSwitch1.

Is that all there is to it?

TIA
