Configuring Voice VLAN Properties
A VLAN is a logical group that enables devices connected to the VLAN 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 VID (VLAN ID) 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 one or more 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.
