Controlling Switch Access with RADIUS Chapter 8 Configuring Switch-Based Authentication Beginning in privileged EXEC mode, follow these steps to define the AAA server group and associate a particular RADIUS server with it: Step 1 Step 2 Command configure terminal radius-server host {hostname | ip-address} [auth-port port-number] [acct-port port-number] [timeout seconds] [retransmit retries] [key string] Step 3 aaa new-model Step 4 aaa group server radius group-name Step 5 server ip-address Step 6 end Step 7 show running-config Purpose Enter global configuration mode. Specify the IP address or hostname 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 switch waits for the RADIUS server to reply before resending. 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 switch 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 switch 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 switch 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. Enable AAA. Define the AAA server-group with a group name. This command puts the switch in a server group configuration mode. Associate a particular RADIUS server with the defined server group. Repeat this step for each RADIUS server in the AAA server group. Each server in the group must be previously defined in Step 2. Return to privileged EXEC mode. Verify your entries. 8-26 Catalyst 2960 Switch Software Configuration Guide OL-8603-04

Chapter 8
Configuring Switch-Based Authentication
Controlling Switch Access with RADIUS
Beginning in privileged EXEC mode, follow these steps to define the AAA server group and associate a
particular RADIUS server with it:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
radius-server host
{
hostname
|
ip-address
} [
auth-port
port-number
]
[
acct-port
port-number
] [
timeout
seconds
] [
retransmit
retries
] [
key
string
]
Specify the IP address or hostname 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
switch waits for the RADIUS server to reply before resending. 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 switch 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 switch 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 switch 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.
Step 3
aaa new-model
Enable AAA.
Step 4
aaa group server radius
group-name
Define the AAA server-group with a group name.
This command puts the switch in a server group configuration mode.
Step 5
server
ip-address
Associate a particular RADIUS server with the defined server group.
Repeat this step for each RADIUS server in the AAA server group.
Each server in the group must be previously defined in Step 2.
Step 6
end
Return to privileged EXEC mode.
Step 7
show running-config
Verify your entries.
