Router Interaction with RADIUS Servers Overview

To identify the RADIUS servers that the router can use and to configure how the router interacts with the servers, you include the radius-server statement at the [edit access] hierarchy level. You can specify multiple RADIUS servers on the network.



[edit access]

radius-server server-address {
accounting-port port-number;
port port-number;

retry attempts; 
secret password;
source-address source-address;
timeout seconds; 
}

The following list describes the radius-server configuration statements:

server-address—The address of the RADIUS server to use. To configure more than one RADIUS server, include multiple server-address entries.
accounting-port—The RADIUS server accounting port number. The default accounting port number is 1813.
port-number—The port number used to contact the RADIUS server. The default is port number 1812.
retry—The number of times that the router attempts to contact a RADIUS accounting server. You can configure the router to retry from 1 through 16 times. The default setting is 3 retry attempts.
secret—The required secret (password) that the local router passes to the RADIUS client. Secrets can contain spaces.
source-address—A source address for the RADIUS server. Each RADIUS request sent to a RADIUS server uses the specified source address. The source address is a valid IPv4 address configured on one of the router interfaces.
timeout—The length of time that the local router waits to receive a response from a RADIUS server. By default, the router waits 3 seconds. You can configure the timeout to be from 1 through 90 seconds.
