VLAN Virtual Local Area Network. A network of computers that behave as if
they are connected to the same wire when they may be physically
located on different segments of a LAN. VLANs are configured
through software rather than hardware, which makes them extremely
flexible. When a computer is physically moved to another location, it
can stay on the same VLAN without any hardware reconfiguration.
The standard is defined in IEEE 802.1Q - Virtual LANs, which states
that “IEEE 802 Local Area Networks (LANs) of all types may be
connected together with Media Access Control (MAC) Bridges, as
specified in ISO/IEC 15802-3. This standard defines the operation of
Virtual LAN (VLAN) Bridges that permit the definition, operation and
administration of Virtual LAN topologies within a Bridged LAN
infrastructure.”
WM-AD WM Access Domain Services (WM-AD). An Extreme Networks-
specific technique that provides a means of mapping wireless
networks to a wired topology.
VoIP Voice Over Internet Protocol. An internet telephony technique. With
VoIP, a voice transmission is cut into multiple packets, takes the most
efficient path along the Internet and is reassembled when it reaches
the destination.
VPN Virtual Private Network. A private network that is constructed by
using public wires to connect nodes. These systems use encryption
and other security mechanisms to ensure that only authorized users
can access the network and that the data cannot be intercepted.
VSA Vendor Specific Attribute, an attribute for a RADIUS server defined by
the manufacturer.(compared to the RADIUS attributes defined in the
original RADIUS protocol RFC2865). A VSA attribute is defined in
order that it can be returned from the RADIUS server in the Access
Granted packet to the Radius Client.
W

WEP Wired Equivalent Privacy. A security protocol for wireless local area
networks (WLANs) defined in the 802.11b standard. WEP aims to
provide security by encrypting data over radio waves so that it is
protected as it is transmitted from one end point to another.
Wi-Fi Wireless fidelity. A term referring to any type of 802.11 network,
whether 802.11b, 802.11a, dual-band, etc. Used in reference to the Wi-
Fi Alliance, a nonprofit international association formed in 1999 to
certify interoperability of wireless Local Area Network products based
on IEEE 802.11 specification.
