Chapter 8 Configuring Switch-Based Authentication Controlling Switch Access with RADIUS Configuring the Switch for Vendor-Proprietary RADIUS Server Communication Although an IETF draft standard for RADIUS specifies a method for communicating vendor-proprietary information between the switch and the RADIUS server, some vendors have extended the RADIUS attribute set in a unique way. Cisco IOS software supports a subset of vendor-proprietary RADIUS attributes. As mentioned earlier, to configure RADIUS (whether vendor-proprietary or IETF draft-compliant), you must specify the host running the RADIUS server daemon and the secret text string it shares with the switch. You specify the RADIUS host and secret text string by using the radius-server global configuration commands. Beginning in privileged EXEC mode, follow these steps to specify a vendor-proprietary RADIUS server host and a shared secret text string: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Command configure terminal radius-server host {hostname | ip-address} non-standard radius-server key string end show running-config copy running-config startup-config Purpose Enter global configuration mode. Specify the IP address or hostname of the remote RADIUS server host and identify that it is using a vendor-proprietary implementation of RADIUS. Specify the shared secret text string used between the switch and the vendor-proprietary RADIUS server. The switch and the RADIUS server use this text string to encrypt passwords and exchange responses. Note The key is a text string that must match the encryption key used on the RADIUS server. Leading spaces are ignored, but spaces within and at the end of the key are used. If you use spaces in your key, do not enclose the key in quotation marks unless the quotation marks are part of the key. Return to privileged EXEC mode. Verify your settings. (Optional) Save your entries in the configuration file. To delete the vendor-proprietary RADIUS host, use the no radius-server host {hostname | ip-address} non-standard global configuration command. To disable the key, use the no radius-server key global configuration command. This example shows how to specify a vendor-proprietary RADIUS host and to use a secret key of rad124 between the switch and the server: Switch(config)# radius-server host 172.20.30.15 nonstandard Switch(config)# radius-server key rad124 Displaying the RADIUS Configuration To display the RADIUS configuration, use the show running-config privileged EXEC command.
