Chapter 6 Configuring the System
Controlling Switch Access with RADIUS
Beginning in privileged EXEC mode, follow these steps to specify a vendor-proprietary RADIUS server
host and a shared secret text string:
To delete the vendor-proprietary RADIUS host, use the no radius-server host {hostname | ip-address}
non-standard command. To disable the key, use the no radius-server key 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.

switch and the vendor-proprietary RADIUS server.
The switch and the RADIUS server use this text
string to encrypt passwords and exchange responses.

encryptionkeyusedontheRADIUSserver.
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.
