2.2.1 Adding Servers

You can add one or more RADIUS/TACACS+ servers on the switch for authentication. If
multiple servers are added, the server with the highest priority authenticates the users
trying to access the switch, and the others act as backup servers in case the first one
breaks down.
■ Adding RADIUS Server
Follow these steps to add RADIUS server on the switch:
Step 1
Step 2
Step 3
Step 4
configure
Enter global configuration mode.
radius-server host ip-address [ auth-port port-id ] [ acct-port port-id ] [ timeout time ] [
retransmit number ] [ nas-id nas-id ] key { [ 0 ] string | 7 encrypted-string }
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 { [ 0 ] string | 7 encrypted-string }:
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.
show radius-server
Verify the configuration of RADIUS server.
