RADIUS Authentication and Accounting

Configuring the Switch for RADIUS Authentication

For example, suppose that your switch is configured to use three RADIUS servers for authenticating access through Telnet and SSH. Two of these servers use the same encryption key. In this case your plan is to configure the switch with the following global authentication parameters:

■Allow only two tries to correctly enter username and password.

■Use the global encryption key to support the two servers that use the same key. (For this example, assume that you did not configure these two servers with a server-specific key.)

■Use a dead-time of five minutes for a server that fails to respond to an authentication request.

■Allow three seconds for request timeouts.

■Allow two retries following a request that did not receive a response.
