VLAN Management 12 VLANs This section covers the following topics: • VLANs • Configuring Default VLAN Settings • Creating VLANs • Configuring VLAN Interface Settings • Defining VLAN Membership • Voice 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 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. 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.
