Configuring RADIUS
Step 3
Router (config)# 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 4
Router (config)# aaa group server
radius
group-name
Define the AAA server-group with a group name.
This command puts the ML-Series card in a server group configuration
mode.
Step 5
Router (config-sg-radius)# 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
Router (config-sg-radius)# end
Return to privileged EXEC mode.
Step 7
Router # show running-config
Verify your entries.
Step 8
Router # copy running-config
startup-config
(Optional) Save your entries in the configuration file.
Step 9
Enable RADIUS login authentication. See the
Authentication” section on page 19-11
