 To define RADIUS servers, go to “Defining RADIUS Server Groups”.
 Click Finish to save the changes and close the wizard.
Defining RADIUS
Server Groups
A server group is a group of one to four RADIUS servers. Server groups
enable RADIUS server redundancy by allowing another server to be used
if the first server is unavailable. You must create at least one server group,
even if you are using only one RADIUS server. You can specify the order
in which servers are used for authentication. You can also specify load
balancing, which uses all servers in a group using a round-robin
algorithm.
To define a RADIUS server group
1 Access the WX Switch wizard for the WX switch. (See “Accessing the WX
Switch Wizard” on page 187.)
2 Select AAA at the top of the wizard, if not already selected.
3 Select RADIUS Server Group from the organizer list on the left side of the
page, if not already selected.
4 Click New RADIUS Server Group. The Create RADIUS Server Group
wizard appears.
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.
