VLAN Management

This section covers the following topics:

•VLANs

•Configuring Default VLAN Settings

•Creating VLANs

•Configuring VLAN Interface Settings

•Defining VLAN Membership

•GVRP Setting s

•VLAN Groups

•Voice VL AN

•Access Port Multicast TV VL AN

•Customer Port Multicast TV VLAN

VLANs

A VLAN is a logical group of ports that enables devices associated with it to

communicate with each other over the Ethernet MAC layer, regardless of the

physical LAN segment of the bridged network to which they are connected.
