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 failover

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.

Configuring AAA Server Group

To define the AAA server group and associate a particular RADIUS server with it, follow these steps, beginning

in privileged EXEC mode:

SUMMARY STEPS

configure terminal

aaa new-model

radius-server host {hostname | ip-address } [auth-port port-number ] [acct-port port-number ] [timeout

seconds ] [retransmit retries ] [key string ]

aaa group server radius group-name

server ip-address

end

show running-config

copy running-config startup-config

DETAILED STEPS

PurposeCommand or Action

Enters global configuration mode.configure terminal

Step 1

Enables AAA.aaa new-model

Step 2

Specifies the IP address or hostname of the remote RADIUS server host.

radius-server host {hostname

| ip-address } [auth-port

Step 3

• auth-port port-number—(Optional) Specifies the user datagram protocol (UDP)

destination port for authentication requests.

port-number ] [acct-port

port-number ] [timeout

seconds ] [retransmit retries ]

[key string ]

• acct-port port-number—(Optional) Specifies the UDP destination port for

accounting requests.

• timeout seconds —(Optional) The time interval that the wireless device 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.

• retransmit retries—(Optional) The number of times that 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.
