Configuring and Managing Access Rules for Administrative Users
To set the authentication method for administrator access
1 At the top of the Create Admin Access wizard, select Authentication. The
Authentication page appears.
2 To enable this authentication rule, select Enabled.
3 To select the authentication method, click Choose Available, then select
the method from the list:
RADIUS server group — A server group that you have configured
previously.
LOCAL — The WX switch's local database.
You can add one or both methods to the list.
If you specify a RADIUS server group as the first method and a user is
denied access by the RADIUS server, no authentication and
authorization are attempted with the other methods specified in the
list.
If you specify LOCAL as the first method and a user is not in the local
user database on the WX, authentication and authorization are
attempted with a RADIUS server group if one is defined in the method
list.
The method you select for authentication is also used for authorization.
