VLAN Commands
A VLAN is a group of ports that can be located anywhere in the network,
but communicate as though they belong to the same physical segment.
This section describes commands used to create VLAN groups, add port
members, specify how VLAN tagging is used, and enable automatic
VLAN registration for the selected interface.
