Example #2: MAC-Based Authentication Mode
The PowerConnect 6200 Series 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.
The following command enables MAC-based authentication on port 1/g8 and limits the number of
devices that can authenticate on that port to 3. The switchport mode general command sets the
port to an 802.1Q VLAN. The port must be in general mode in order to enable MAC-based 802.1X
authentication.
