Chapter 13 Configuring RADIUS and TACACS+ Servers
 Configuring and Enabling RADIUS
For a complete list of RADIUS attributes or more information about VSA 26, refer to the “RADIUS 
Attributes” appendix in the Cisco IOS Security Configuration Guide for Release 12.2. 
Configuring the Access Point for Vendor-Proprietary RADIUS Server Communication
Although an IETF draft standard for RADIUS specifies a method for communicating vendor-proprietary 
information between the access point 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 
access point. 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:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
radius-server vsa send [accounting | 
authentication]
Enable the access point to recognize and use VSAs as defined by RADIUS 
IETF attribute 26.
• (Optional) Use the accounting keyword to limit the set of recognized 
vendor-specific attributes to only accounting attributes.
• (Optional) Use the authentication keyword to limit the set of 
recognized vendor-specific attributes to only authentication attributes.
If you enter this command without keywords, both accounting and 
authentication vendor-specific attributes are used.
Step 3
end Return to privileged EXEC mode.
Step 4
show running-config Verify your settings.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
radius-server host {hostname | ip-address} non-standard  Specify the IP address or host name of the remote 
RADIUS server host and identify that it is using a 
vendor-proprietary implementation of RADIUS.
