Create a VLAN
A VLAN is created when you assign it a VLAN ID.
A VLAN is active only if the VLAN contains interfaces and those interfaces are up. VLAN 1 is inactive 
because it contains the interfaces that are not up. When you delete a VLAN (
no interface vlan vlan-id), any 
interfaces assigned to that VLAN are reassigned to the default VLAN as untagged.
