RADIUS
The Remote Authentication Dial-in User Service (RADIUS) configuration page is used for setup and
maintenance of all settings required to enable RADIUS support.
Enabling or disabling RADIUS support:
Select Enabled or Disabled from the RADIUS drop-down menu and click Apply.
Configuring the authentication order:
Select Remote > Local or Remote Only from the drop-down menu and click Apply.
NOTE: Server Technology recommends not setting the authentication order to Remote Only until RADIUS has been
configured and tested.
Changing the RADIUS server address:
Enter the IP address or hostname in the Primary and/or Secondary Server field and click Apply.
Setting the RADIUS shared secret:
The shared secret is the RADIUS authentication key.
Enter the shared secret in the Primary and Secondary Shared Secret field. Up to 48 upper and lowercase
alphanumeric and other typed characters (ASCII 33 to 126 decimal) and spaces are allowed; control
characters are not allowed. Click Apply.
To change the shared secret, check the Change checkbox to clear the Shared Secret field, enter the new
shared secret, and click Apply.
Changing the RADIUS server port:
This field specifies the port number used by the RADIUS server for incoming RADIUS authentication
requests.
Enter the port number in the Primary and/or Secondary Port field and click Apply.
The valid port number range is 1-65535; default is 1812.
Setting the RADIUS server timeout value:
The Timeout field specifies the time interval (in seconds) to wait for a reply from the RADIUS server
before resending an authentication request.
Enter the timeout value (in seconds) in the Primary and/or Secondary Timeout field and click Apply.
The valid timeout range is 1-30 seconds; default is 5 seconds.
Setting the number of RADIUS server retries:
The Set RADIUS Retries command specifies the number of times an authentication request is sent to
the RADIUS server. The PT22 will attempt authentication with the primary server until the number of
retries is reached, then will attempt authentication with the secondary server. If the unit does not receive
a response from these attempts, the authentication request will be rejected.
Setting the number of retries:
At the Switched CDU: prompt, type set radius, followed by primary or secondary, followed by retries,
and followed by the number of retries (0-10). Click Enter.
Examples
The following command sets the retries for the primary RADIUS server to 5:
Switched CDU: set radius primary retries 5<Enter>
The following command sets the retries for the secondary RADIUS server to 2:
Switched CDU: set radius secondary retries 2<Enter>
