LABEL DESCRIPTION
ReAuthentication
Timer (in seconds) Specify how often wireless stations have to reenter usernames and passwords in
order to stay connected. Enter a time interval between 10 and 9999 seconds. The
default time interval is 1800 seconds (30 minutes).
If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server has
priority.
Idle Timeout The Prestige automatically disconnects a wireless station from the wired network
after a period of inactivity. The wireless station needs to enter the username and
password again before access to the wired network is allowed. The default time
interval is 3600 seconds (or 1 hour).
Authentication
Databases The authentication database contains wireless station login information. The local
user database is the built-in database on the Prestige. The RADIUS is an external
server. Use this drop-down list box to select which database the Prestige should use
(first) to authenticate a wireless station.
Before you specify the priority, make sure you have set up the corresponding
database correctly first.
Select Local User Database Only to have the Prestige just check the built-in user
database on the Prestige for a wireless station's username and password.
Select RADIUS Only to have the Prestige just check the user database on the
specified RADIUS server for a wireless station's username and password.
Select Local first, then RADIUS to have the Prestige first check the user database
on the Prestige for a wireless station's username and password. If the user name is
not found, the Prestige then checks the user database on the specified RADIUS
server.
Select RADIUS first, then Local to have the Prestige first check the user database
on the specified RADIUS server for a wireless station's username and password. If
the Prestige cannot reach the RADIUS server, the Prestige then checks the local
user database on the Prestige. When the user name is not found or password does
not match in the RADIUS server, the Prestige will not check the local user database
and the authentication fails.
Preamble Select a preamble type from the drop-down list menu. Choices are Long, Short or
Dynamic. The default setting is Long. See the section on preamble for more
