VSA
Vendor-specic attribute. A type of RADIUS attribute that enables a vendor to extend
RADIUS operations to t its own products, without conicting with existing RADIUS attributes
or the VSAs of other companies. Companies can create new authentication and accounting
attributes as VSAs.
WECA
Wireless Ethernet Compatibility Alliance. See Wi-Fi Alliance.
WEP
Wired-Equivalent Privacy protocol. A security protocol, specied in the IEEE 802.11 standard,
that attempts to provide a wireless LAN (WLAN) with a minimal level of security and privacy
comparable to a typical wired LAN. WEP encrypts data transmitted over the WLAN to protect
the vulnerable wireless connection between users (clients) and access points (APs). Although
appropriate for most home use, WEP is weak and fundamentally awed for enterprise use.
Compare AES; CCMP; TKIP.
Wi-Fi Alliance
An organization formed by leading wireless equipment and software providers, for certifying
all IEEE 802.11 wireless LAN (WLAN) products for interoperability and promoting the term
WiFi as their global brand name. Only products that pass WiFi Alliance testing can be certied.
Certied products are required to carry an identifying seal on their packaging stating that the
product is Wi-Fi certied and indicating the radio frequency band used (2.4 GHz for 802.11b
and 5 GHz for 802.11a, for example). The WiFi Alliance was formerly known as the Wireless
Ethernet Compatibility Alliance (WECA).
Wi-Fi Protected Access
See WPA.
wildcard mask
A 32-bit quantity used with an IP address to determine which bits in the address to ignore in
a comparison with another IP address. When setting up security access control lists (ACLs),
you specify source and destination IP addresses and corresponding wildcard masks by which
the switch determines whether to forward or lter packets. The security ACL checks the bits in
IP addresses that correspond to any 0s (zeros) in the mask, but does not check the bits that
correspond to 1s (ones) in the mask.
wired authentication port
An Ethernet port that has 802.1X authentication enabled for access control.
