Radius Server Configuration; Disabling Radius For Epicenter - Extreme Networks EPICenter Reference Manual

4 Enter the RADIUS server's shared secret in the RADIUS Secret field for both the primary and
secondary RADIUS servers.
This shared secret is a shared key by which the RADIUS server and its clients recognize each other,
and which they use for secure transmission of user passwords.
NOTE
If the shared secret is changed in either of the RADIUS servers, you must change it in EPICenter as well, or else
EPICenter will no longer be able to access the RADIUS server.
5 Click Apply to have the configuration changes take effect.
NOTE
Some configuration may be required on the external RADIUS server to allow EPICenter to authenticate users with
various roles. See the EPICenter Concepts and Solutions Guide for a full explanation of how to configure an external
RADIUS server to perform EPICenter user authentication.

RADIUS Server Configuration

To configure EPICenter as a RADIUS server, follow these steps:
1 Click the Enable EPICenter as a RADIUS Server button in the RADIUS Configuration panel at the
top of the page.
This enables the fields in the Server Configuration panel.
2 Enter the RADIUS server's shared secret in the RADIUS Secret field.
NOTE
If you change the secret in the RADIUS server, you must also change it in any of the RADIUS clients (Extreme
switches) that use the RADIUS server for user authentication.
3 The default port used for the RADIUS server is 1645. To change the server port, enter the port
number in the RADIUS Port field.
NOTE
If you change the RADIUS server port, you must make sure that the port used by any RADIUS clients (Extreme
switches that use this RADIUS server for user authentication) match the port you enter for the server.
4 To disable RADIUS response messages, uncheck the Enable RADIUS Response Messages checkbox.
This prevents the RADIUS server from sending a response message when authentication fails. Check
the box to enable these messages. This is enabled by default.
5 Click Apply to have the configuration changes take effect.
