Add the RADIUS server and configure the related parameters as needed.
host
ip-address
:
Enter the IP address of the server running the RADIUS protocol.
auth-port
port-id
:
Specify the UDP destination port on the RADIUS server for authentication
requests. The default setting is 1812.
acct-port
port-id:
Specify the UDP destination port on the RADIUS server for accounting
requests. The default setting is 1813. Usually, it is used in the 802.1X feature.
timeout
time
:
Specify the time interval that the switch waits for the server to reply before
resending. The valid values are from 1 to 9 seconds and the default setting is 5 seconds.
retransmit
number
:
Specify the number of times a request is resent to the server if the
server does not respond. The valid values are from 1 to 3 and the default setting is 2.
nas-id
nas-id
:
Specify the name of the NAS (Network Access Server) to be contained in
RADIUS packets for identification. It ranges from 1 to 31 characters. The default value is the
MAC address of the switch. Generally, the NAS indicates the switch itself.
key {

string

7
encrypted-string
}
:
Specify the shared key. 0 and 7 represent the
encryption type. 0 indicates that an unencrypted key will follow. 7 indicates that a
symmetric encrypted key with a fixed length will follow. By default, the encryption type is 0.
string
is the shared key for the switch and the server, which contains 32 characters at most.
encrypted-string
is a symmetric encrypted key with a fixed length, which you can copy from
the configuration file of another switch. The key or encrypted-key you configure here will be
displayed in the encrypted form.
Step 3
show radius-server
Verify the configuration of RADIUS server.
Step 4
end
Return to privileged EXEC mode.
Step 5
copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to add a RADIUS server on the switch. Set the IP address
of the server as 192.168.0.10, the authentication port as 1812, the shared key as 123456,
the timeout as 8 seconds and the retransmit number as 3.
