Configuration Procedure
z
Make sure that the terminals, the servers and the switch are reachable to each other.
z
If using an external DHCP server, ensure that the terminals can get IP addresses from the server
before and after authentication.
z
Complete the configuration on the RADIUS server and make sure the authentication, authorization
and accounting functions work normally. In this example, you need to configure on the RADIUS
server an 802.1X user (with username userdot), a Web user (with username userpt) and a MAC
authentication user (with a username and password both being the MAC address of the printer
001588f80dd7).
z
For information about DHCP, MAC address authentication, and Web authentication, refer to DHCP
Operation, MAC Address Authentication Operation, and Web Authentication Operation.

is recommended to shorten the time terminals use to re-acquire IP addresses after passing or failing
authentication.
