Configuring 802.1X and Port-Based Security 537
3 Enable 802.1X port-based access control on the switch.
console(config)#dot1x system-auth-control
4 Configure ports 9 and 24 to be in the Authorized state, which allows the
devices to connect to these ports to access the switch services without
authentication.
console(config)#interface range gi1/0/9-10
console(config-if)#dot1x port-control force-
authorized
console(config-if)#exit
5 Configure Port 7 to require MAC-based authentication with MAB.
console(config)#interface gi1/0/7
console(config-if-Gi1/0/7)#dot1x port-control mac-
based
console(config-if-Gi1/0/7)#dot1x mac-auth-bypass
6 Set the port to an 802.1Q VLAN. It is recommended to configure the port
as to be in general mode in order to enable MAC-based 802.1X
authentication.
console(config-if-Gi1/0/7)#switchport mode general
console(config-if-Gi1/0/7)#exit
console(config-if-Gi1/0/7)#exit
7 View the client connection status.
When the clients on Ports 1, 3, and 7(supplicants), attempt to
communicate via the switch, the switch challenges the supplicants for
login credentials. The switch encrypts the provided information and
transmits it to the RADIUS server. If the RADIUS server grants access, the
system sets the 802.1X port state of the interface to authorized and the
supplicants are able to access network resources.
