Configure an EAP-enabled RADIUS Server

The switch uses RADIUS servers for authentication and accounting services. Use the no form to delete a RADIUS server.

Before you begin

You must enable EAP globally.

About this task

The RADIUS server uses the secret key to validate users.

RADIUS supports IPv4 and IPv6 addresses, with no difference in functionality or configuration.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Add an EAP-enabled RADIUS server:

radius server host WORD <0–46> used-by eapol acct-enable

radius server host WORD <0–46> used-by eapol acct-port <1-65536>

radius server host WORD <0–46> used-by eapol enable

radius server host WORD <0–46> used-by eapol key WORD<0-20>

radius server host WORD <0–46> used-by eapol port <1-65536>

radius server host WORD <0–46> used-by eapol priority <1-10>

radius server host WORD <0–46> used-by eapol retry <0-6>

radius server host WORD <0–46> used-by eapol secure-enable

radius server host WORD <0–46> used-by eapol secure-log-level

radius server host WORD <0–46> used-by eapol secure-mode

radius server host WORD <0–46> used-by eapol secure-profile

radius server host WORD <0–46> used-by eapol source-ip WORD <0–46>

radius server host WORD <0–46> used-by eapol timeout <1-180>

By default, the switch uses RADIUS UDP port 1812 for authentication, and port 1813 for accounting. You can change the port numbers or other RADIUS server options.

Example

Add an EAP RADIUS server:

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#radius server host fe80:0:0:0:21b:4fff:fe5e:73fd key radiustest used-by eapol
