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.
