VLAN Management
This section covers the following topics:
• Regular VLANs
• Private VLAN Settings
• GVRP Settings
• VLAN Groups
• Voice VLAN
• Access Port Multicast TV VLAN
• Customer Port Multicast TV VLAN
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.
VLAN Description
Each VLAN is configured with a unique VLAN ID (VID) with a value from 1 to 4094. A port
on a device in a bridged network is a member of a VLAN if it can send data to and receive data
from the VLAN. A port is an untagged member of a VLAN if all packets destined for that port
into the VLAN have no VLAN tag. A port is a tagged member of a VLAN if all packets
destined for that port into the VLAN have a VLAN tag. A port can be a member of only one
untagged VLAN but can be a member of multiple tagged VLANs.
A port in VLAN Access mode can be part of only one VLAN. If it is in General or Trunk
mode, the port can be part of one or more VLANs.
VLANs address security and scalability issues. Traffic from a VLAN stays within the VLAN,
and terminates at devices in the VLAN. It also eases network configuration by logically
connecting devices without physically relocating those devices.
