Deleting Radius Servers; Configuring Radius Server Groups; Creating Server Groups - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

Note: You must provide RADIUS servers with names that are unique. To prevent confusion, D-Link
recommends that RADIUS server names differ in ways other than case. For example, avoid naming two
servers RS1 and rs1.
You must configure RADIUS servers into server groups before you can access them.
To remove a RADIUS server from the switch configuration, use the following command:
clear radius server server-name

Configuring RADIUS Server Groups

A server group is a named group of up to four RADIUS servers. Before you can use a RADIUS server
for authentication, you must first create a RADIUS server group and add the RADIUS server to that
group. You can also arrange load balancing, so that authentications are spread out among servers in the
group. You must declare all members of a server group, in contact order, when you create the group.
Once the group is configured, you can use a server group name as the AAA method with the set
authentication and set accounting commands.
Subsequently, you can change the members of a group or configure load balancing.
If you add or remove a RADIUS server in a server group, all the RADIUS dead timers for that server
group are reset to the global default.
To create a server group, you must first configure the RADIUS servers with their addresses and any
optional parameters. After configuring RADIUS servers, type the following command:
set server group group-name members server-name1 [server-name2]
[server-name3] [server-name4]
For example, to create a server group called shorebirds with the RADIUS servers heron, egret, and
sandpiper, type the following commands:
DWS-1008# set radius server egret address 192.168.253.1 key apple
DWS-1008# set radius server heron address 192.168.253.2 key pear
DWS-1008# set radius server sandpiper address 192.168.253.3 key plum
DWS-1008# set server group shorebirds members egret heron sandpiper
In this example, a request to shorebirds results in the RADIUS servers being contacted in the order that
they are listed in the server group configuration, first egret, then heron, then sandpiper. You can change
the RADIUS servers in server groups at any time.
