Modifying the Properties of an Existing Radius Server
Some of the attributes of an existing Radius Server can be modified by the controller to better reflect the
Radius Server’s existing connection with the controller.
To modify the attributes of an existing Radius Server:
1 Select Management Access > Users from the main menu tree.
The Users screen displays.
2
Click on the Authentication tab.
3 Select an existing Radius Server from those listed and click the Edit button at the bottom of the
screen.
Shared secret
Displays the shared secret used to verify Radius messages (with the
exception of the Access-Request message) are sent by a Radius-enabled
device configured with the same shared secret. The shared secret is a
case-sensitive string (password) that can include letters, numbers, or
symbols. Ensure the shared secret is at least 22 characters long to
protect the Radius Server from brute-force attacks.
Retries
Displays the maximum number of times the controller can retransmit a
Radius Server frame before it times out of the authentication session.
Timeout
Displays the maximum time (in seconds) the controller waits for the
Radius Server’s acknowledgment of authentication request packets before
the controller times out of the session.
