Appendix D - Glossary
attribute
In authentication, authorization, and accounting (AAA), a property used to identify (authenticate)
a user or to configure (authorize) or record (account for) a user’s administrative or network
session. A user’s AAA attributes are stored in a user profile in the local database on a DWS-
1008 switch, or on a RADIUS server. Attribute names are casesensitive. See also

;
VSA
.
authenticated identity
In a D-Link network, the correspondence established between a user and his or her
authentication attributes. User authentication attributes are linked to the
user
, rather than
to a physical port or device, regardless of the user’s location or type of network connection.
Because the authenticated identity follows the user, he or she requires no reauthentication
when roaming.

authentication mobility
The ability of a user (client) authenticated via Extensible Authentication Protocol (EAP)—
plus an appropriate subprotocol and back-end authentication, authorization, and accounting
(AAA) service—to roam to different access points (APs) without reauthentication.
authentication server
An entity that provides an authentication service to an authenticator. From the credentials
provided by a client (or
supplicant
), the authentication service determines whether the
supplicant is authorized to access the services of the authenticator. In a D-Link network, one
or more RADIUS servers can act as authentication servers.
authenticator
A device that authenticates a client.

bias
The priority of one DWS-1008 switch over other switches for booting, configuring, and
providing data transfer for a DWL-8220AP access point. Bias can be set to either low or
high on each DWS-1008 switch and is high by default. Bias applies only to switches that
are indirectly attached to the AP through an intermediate Layer 2 or Layer 3 network. An AP
always attempts to boot on AP port 1 first, and if the AP is directly attached to a switch on AP
port 1, the AP uses the directly attached switch to boot from regardless of the bias settings.
