UPnP
UPnP is an acronym for Universal Plug and Play. The goals of UPnP are to allow devices to
connect seamlessly and to simplify the implementation of networks in the home (data sharing,
communications, and entertainment) and in corporate environments for simplified installation
of computer components
User Priority
User Priority is a 3-bit field storing the priority level for the 802.1Q frame. It is also known as
PCP.
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
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.
Voice VLAN
Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice
devices attached to voice VLAN, we can perform QoS-related configuration for voice data,
ensuring the transmission priority of voice traffic and voice quality.
W
WEP
WEP is an acronym for Wired Equivalent Privacy. WEP is a deprecated algorithm to secure
IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio, so are
more susceptible to eavesdropping than wired networks. When introduced in 1999, WEP was
intended to provide confidentiality comparable to that of a traditional wired network
1 and members of VLAN 1. This means that MAC addresses are learned
