4.3.12 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.
