Appendix A:Glossary 727Nortel WLAN—Security Switch 2300 Series Configuration Guideuser A person who uses a client. In a Nortel WLAN 2300 system, users are indexed by username andassociated with authorization attributes such as user group membership.user wildcard A Nortel convention for matching fully qualified structured usernames or sets ofusernames during authentication by means of known characters plus two special “wildcard” characters.Double asterisks (**) represent all usernames. A single asterisk (*) can appear either before or after thedelimiter in a user wildcard and can represent any number of characters up to the next delimiter. A delimitercan be an at (@) sign or a dot (.). See also MAC address wildcard; VLAN wildcard.user group A collection of users with the same authorization attributes.vendor-specific attribute See VSA.virtual LAN See VLAN.VLAN Virtual LAN. A set of ports that share a single Layer 2 network. Because the ports that constitute aVLAN can be on a single network device or multiple devices, VLANs enable you to partition a physicalnetwork into logical networks that meet the needs of your organization. You can divide a single device intomultiple logical Layer 2 switches, with each VLAN operating as a separate switch, or make multiple devicesmembers of multiple logical Layer 2 networks. By default, all WLAN—Security Switch (WSS) ports aremembers of VLAN 1, which is named default.VLAN wildcard A Nortel convention for applying the authentication, authorization, and accounting(AAA) attributes in the location policy on a WSS to one or more users, based on a virtual LAN (VLAN)attribute. To specify all VLANs, use the double-asterisk (**) wildcard characters. To match any number ofcharacters up to, but not including a delimiter character in the wildcard, use the single-asterisk wildcard. ValidVLAN wildcard delimiter characters are the at (@) sign and the dot (.). See also location policy; MAC addresswildcard; user wildcard.Voice over IP See VoIP.VoIP Voice over IP. The ability of an IP network to carry telephone voice signals as IP packets in compliancewith International Telecommunications Union Telecommunication Standardization Sector (ITU-T)specification H.323. VoIP enables a router to transmit telephone calls and faxes over the Internet with no lossin functionality, reliability, or voice quality.VSA Vendor-specific attribute. A type of RADIUS attribute that enables a vendor to extend RADIUSoperations to fit its own products, without conflicting with existing RADIUS attributes or the VSAs of othercompanies. Companies can create new authentication and accounting attributes as VSAs.watch list A WLAN Management Software method for monitoring user location and activity. Afterinitially finding a user through WLAN Management Software, you can add the user to the watch list forcontinued monitoring. WLAN Management Software tracks and displays such information as the AP that auser is associated with during a session, the server that authenticated the user, and the session start and stoptimes.Web View A Web-based application for configuring and managing a single WLAN—Security Switch(WSS) and its attached Access Point (AP) through a Web browser. Web View uses a secure connection thatimplements Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS).WECA Wireless Ethernet Compatibility Alliance. See Wi-Fi Alliance.
