Answer 1

Favourite answer

That's the VLAN ID.

You use it to identify a particular VLAN.

If you have 4 VLANs, you may tag them as: VLAN 10, VLAN 20, VLAN 30, VLAN 40 or however you want.

Answer 2

You can use VLAN-2 if you want to. People tend to spread out their use of VLANs so that they have room to insert news VLANs if needed.  Sort of how one numbers lines in a program.   

 

The VLAN numbers don't mean anything -- they're just the way we keep track of different VLANs. If you want to use VLAN-2, VLAN-3, and VLAN-4 -- go for it.  Others might use VLAN-20, VLAN-30, and VLAN-40, instead.
