User Priority
User Priority is a 3-bit field storing the priority level for the 802.1Q frame.
V
VLAN
Virtual LAN. A method to restrict communication between switch ports. VLANs can be used for the
following applications:
VLAN unaware switching: This is the default configuration. All ports are VLAN unaware with Port VLAN
ID 1 and members of VLAN 1. This means that MAC addresses are learned in VLAN 1, and the switch
does not remove or insert VLAN tags.
VLAN aware switching: This is based on the IEEE 802.1Q standard. All ports are VLAN aware. Ports
connected to VLAN aware switches are members of multiple VLANs and transmit tagged frames. Other
ports are members of one VLAN, set up with this Port VLAN ID, and transmit untagged frames.
Provider switching: This is also known as Q-in-Q switching. Ports connected to subscribers are VLAN
unaware, members of one VLAN, and set up with this unique Port VLAN ID. Ports connected to the
service provider are VLAN aware, members of multiple VLANs, and set up to tag all frames. Untagged
frames received on a subscriber port are forwarded to the provider port with a single VLAN tag. Tagged
frames received on a subscriber port are forwarded to the provider port with a double VLAN tag.
VLAN ID
VLAN ID is a 12-bit field specifying the VLAN to which the frame belongs.
W
WAN
Wide Area Network. A network that connects computers located in geographically separate areas (e.g.
different buildings, cities, countries). The Internet is a wide area network.
