Configuring Network Security AAA Configuration Step 1 Step 2 Step 3 Step 4 Step 5 configure Enter global configuration mode. radius-server host ip-address [ auth-port port-id ] [ acct-port port-id ] [ timeout time ] [ retransmit number ] [ 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. key { [ 0 ] 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 31 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. end Return to privileged EXEC mode. 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.
