On port GigabitEthernet 1/0/1 of the switch, enable MAC authentication and configure ACL 3000.
After the host passes MAC authentication, the RADIUS server assigns ACL 3000 to port
GigabitEthernet 1/0/1 of the switch. As a result, the host can access the Internet but cannot access the
FTP server, whose IP address is 10.0.0.1.

Configuration procedure
Make sure that there is a route available between the RADIUS server and the switch.
In this example, the switch uses the default username type (user MAC address) for MAC
authentication. Therefore, you need to add the username and password of each user on the
RADIUS server correctly.
You need to configure the RADIUS server to assign ACL 3000 as the authorization ACL.
