Controlling Access Point Access with RADIUS
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 use the 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:
Command
Step 1
configure terminal
Step 2
aaa new-model
Step 3
radius-server host {hostname |
ip-address} [auth-port port-number]
[acct-port port-number] [timeout
seconds] [retransmit retries] [key
string]

6-10
Purpose
Enter global configuration mode.
Enable AAA.
Specify the IP address or host name of the remote RADIUS server host.
(Optional) For auth-port port-number, specify the UDP destination
•
port for authentication requests.
(Optional) For acct-port port-number, specify the UDP destination
•
port for accounting requests.
(Optional) For timeout seconds, specify the time interval that the
•
access point waits for the RADIUS server to reply before
retransmitting. The range is 1 to 1000. This setting overrides the
radius-server timeout global configuration command setting. If no
timeout is set with the radius-server host command, the setting of
the radius-server timeout command is used.
(Optional) For retransmit retries, specify the number of times a
•
RADIUS request is resent to a server if that server is not responding
or responding slowly. The range is 1 to 1000. If no retransmit value
is set with the radius-server host command, the setting of the
radius-server retransmit global configuration command is used.
(Optional) For key string, specify the authentication and encryption
•
key used between the access point and the RADIUS daemon running
on the RADIUS server.
Note
The key is a text string that must match the encryption key used
on the RADIUS server. Always configure the key as the last item
in the radius-server host command. Leading spaces are ignored,
but spaces within and at the end of the key are used. If you use
spaces in your key, do not enclose the key in quotation marks
unless the quotation marks are part of the key.
To configure the access point to recognize more than one host entry
associated with a single IP address, enter this command as many times as
necessary, making sure that each UDP port number is different. The
access point software searches for hosts in the order in which you specify
them. Set the timeout, retransmit, and encryption key values to use with
the specific RADIUS host.
