The RADIUS service configuration is performed on a RADIUS scheme basis. In an actual network 
environment, you can either use a single RADIUS server or two RADIUS servers (primary and 
secondary servers with the same configuration but different IP addresses) in a RADIUS scheme. After 
creating a new RADIUS scheme, you should configure the IP address and UDP port number of each 
RADIUS server you want to use in this scheme. These RADIUS servers fall into two types: 
authentication/authorization, and accounting. And for each type of server, you can configure two 
servers in a RADIUS scheme: primary server and secondary server. A RADIUS scheme has some 
parameters such as IP addresses of the primary and secondary servers, shared keys, and types of the 
RADIUS servers. 
In an actual network environment, you can configure the above parameters as required. But you should 
configure at least one authentication/authorization server and one accounting server, and keep the 
RADIUS server port settings on the switch consistent with those on the RADIUS servers. 
 
 
Actually, the RADIUS service configuration only defines the parameters for information exchange 
between switch and RADIUS server. To make these parameters take effect, you must reference the 
RADIUS scheme configured with these parameters in an ISP domain view (refer to 
AAA Configuration). 
 
Creating a RADIUS Scheme 
The RADIUS protocol configuration is performed on a RADIUS scheme basis. You should first create a 
RADIUS scheme and enter its view before performing other RADIUS protocol configurations.
