Procedure 7-24: Provision RADIUS server
Overview
Use this procedure to provision a Remote Authentication Dial In User Service (RADIUS) server on your network for authentication.
An Authentication Server simplifies the authentication and management of users in a large network. One such type of Authentication Server supports the Remote Authentication Dial In User Service (RADIUS) protocol as defined by RFC 2865.
To accomplish the authentication in a secure manner, the RADIUS client and RADIUS server must both be configured with the same shared secret. This secret is used to generate one-way encrypted authenticators that are present in all RADIUS packets. The secret is never transmitted over the network.
To use RADIUS authentication, you need to create an authentication login list, which uses RADIUS as the primary authentication method, and local authentication as a backup method in the event that the RADIUS server cannot be contacted. The authentication list is then associated with the default login.
Before you begin
Prior to performing this procedure:
-
Refer to Before you begin and Required equipment in this chapter.
Step
Complete the following steps to provision a Remote Authentication Dial In User Service (RADIUS) server on your network for authentication.
1 |
From the System View menu, select Administration → Security → Provision Radius Server. Result: The Provision Radius Server window opens. |
2 |
Provision the parameters as required. See Table 7-1, Radius configuration parameters. |
3 |
Click Create to create a server or Delete to delete a server. |
4 |
Important! The system-level RADIUS Authentication parameter must be Enabled to provision the local network element as a RADIUS client. Select View → Equipment to access the system-level parameters and verify that the RADIUS Authentication parameter is Enabled for the network element. If required, select Configuration → Equipment to access the system-level parameters and enable RADIUS Authentication for the network element.
