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 untagged VLAN and can be a member of
several tagged VLANs.
