HP procurve 5300xl Series Access Security Manual page 51

Authentication Server: The entity providing an authentication service to
the switch. In the case of a Series 5300XL switch running Web/MAC-
Authentication, this is a RADIUS server.
Authenticator: In HP ProCurve switch applications, a device such as a Series
5300XL switch that requires a client or device to provide the proper
credentials (MAC address, or username and password) before being
allowed access to the network.
CHAP: Challenge Handshake Authentication Protocol. Also known as
"CHAP-RADIUS".
Client: In this application, an end-node device such as a management station,
workstation, or mobile PC linked to the switch through a point-to-point
LAN link.
Redirect URL: A System Administrator-specified web page presented to an
authorized client following Web Authentication. HP recommends that this
URL be specified when configuring Web Authentication on a switch. See
the command "aaa port-access web-based [e] < port-list > [redirect-url
<url>]" on page 3-20.
Static VLAN: A VLAN that has been configured as "permanent" on the switch
by using the CLI vlan < vid > command or the Menu interface.
Unauthorized-Client VLAN: A conventional, static, untagged, port-based
VLAN previously configured on the switch by the System Administrator.
It is used to provide limited network access and services to clients who
are not authenticated.
