UTHENTICATION
Changing the password applies both to MAC users and to last-resort
users.
All MAC address-authenticated users or last-resort users must share the
same authorization password on the RADIUS server.
10 Click OK.
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.
1 Access the Create RADIUS Server Group wizard:
a Select the Configuration tool bar option.
b In the Organizer panel, click the plus sign next to the WX switch.
c Click the plus sign next to AAA.
d Select RADIUS.
e In the Task List panel, select RADIUS Server Group.
2 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.
3 Click Next.
4 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.
5 To add RADIUS servers to the server group, select the servers in the
Available RADIUS Servers list and click Add.
