Configuring 802.1X and Port-Based Security 539
Configuring MAC-Based Authentication Mode
The PowerConnect M6220, M6348, M8024, and M8024-k switches support
MAC-based 802.1X authentication. This feature allows multiple hosts to
authenticate on a single port. The hosts are distinguished by their MAC
addresses.
When multiple hosts (for example, a PC, a printer, and a phone in the same
office) are connected to the switch on the same port, each of the connected
hosts authenticates separately with the RADIUS server.
To configure the switch:
1 Enable MAC-based authentication on port 8 and limit the number of
devices that can authenticate on that port to 3.console#configure
console(config)#interface gi1/0/8
console(config-if-Gi1/0/8)#dot1x port-control mac-
based
console(config-if-Gi1/0/8)#dot1x max-users 3
2 Set the port to an 802.1Q VLAN. The port must be in general mode in
order to enable MAC-based 802.1X authentication.
console(config-if-Gi1/0/8)#switchport mode general
console(config-if-Gi1/0/8)#exit
console(config)#exit
