Configuring and Enabling RADIUS
Defining AAA Server Groups
You c an c on f i gu re t he a cc e ss po int t o us e AA A ser ve r gr ou p s to g ro up exi st in g se rve r hos ts fo r
authentication. You select a subset of the configured server hosts and use them for a particular service.
The server group is used with a global server-host list, which lists the IP addresses of the selected server
hosts.
Server groups also can include multiple host entries for the same server if each entry has a unique
identifier (the combination of the IP address and UDP port number), allowing different ports to be
individually defined as RADIUS hosts providing a specific AAA service. If you configure two different
host entries on the same RADIUS server for the same service (such as accounting), the second
configured host entry acts as a fail-over backup to the first one.
You u se th e server group server configuration command to associate a particular server with a defined
group server. You can either identify the server by its IP address or identify multiple host instances or
entries by using the optional auth-port and acct-port keywords.
Beginning in privileged EXEC mode, follow these steps to define the AAA server group and associate a
particular RADIUS server with it:
