300 CHAPTER 7: CONFIGURING AUTHENTICATION, AUTHORIZATION, AND ACCOUNTING PARAMETERS
5 In the Name box, type the name of the RADIUS server group (1 to 32
alphanumeric characters, with no spaces or tabs). Do not use the same
name for a RADIUS server and a server group.
6 To enable load balancing in the server group, select Load Balance.
If you enable load balancing, a round-robin approach is used to balance
the load among servers. Authentication and accounting requests for a
given user are always sent to the same server. Each new authentication
event uses the next server in the list.
If load balancing is not enabled, the first server in the list is contacted
first. If the first server does not respond, the second server in the list is
contacted.
7 To add a RADIUS server to the server group, click Choose Available.
8 Select a RADIUS server from the list.
When you add a RADIUS server to a RADIUS server group, all RADIUS
timers for the server group are restarted.
9 To add more servers (up to four maximum) to the group, repeat step 7
and step 8.
