Chapter 34: 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.

information in order to automatically register VLAN members on interfaces across
the network. This section describes how to enable GVRP for individual interfaces
and globally for the switch, as well as how to display default configuration settings
for the Bridge Extension MIB.
