Web and MAC Authentication for the Series 2600/2600-PWR and 2800 Switches
Configuring Web Authentication on the Switch
Syntax: aaa port-access web-based [e] < port-list > [quiet-period <1 - 65535>]
Specifies the time period, in seconds, the switch should
wait before attempting an authentication request for
a client that failed authentication.
(Default: 60 seconds)
Syntax: aaa port-access web-based [e] < port-list > [reauth-period <0 - 9999999>]
Specifies the time period, in seconds, the switch
enforces on a client to re-authenticate. When set to
0,
reauthentication is disabled. (Default: 300 seconds)
Syntax: aaa port-access web-based [e] < port-list > [reauthenticate]
Forces a reauthentication of all attached clients on the
port.
Syntax: aaa port-access web-based [e] < port-list > [redirect-url <url>]
no aaa port-access web-based [e] < port-list > [redirect-url]
Specifies the URL that a user is redirected to after a
successful login. Any valid, fully-formed URL may be
used, for example, http://welcome-server/welcome.htm
or http://192.22.17.5. HP recommends that you provide
a redirect URL when using Web Authentication.
Use the no form of the command to remove a specified
redirect URL.
(Default: There is no default URL. Browser behavior
for authenticated clients may not be acceptable.)
Syntax: aaa port-access web-based [e] < port-list > [server-timeout <1 - 300>]
Specifies the period, in seconds, the switch waits for a
server response to an authentication request. Depend­
ing on the current
max-requests value, the switch sends
a new attempt or ends the authentication session.
(Default: 30 seconds)
