Chapter 50 MAB Configuration
50.1 Introduction to MAB
In actual network existing the device which can not install the authentication client, such as
printer, PDA devices, they can not process 802.1x authentication. However, to access the
network resources, they need to use MAB authentication to replace 802.1x authentication.
MAB authentication is a network accessing authentication method based on the accessing
port and the MAC address of MAB user. The user needn't install any authentication client, after
the authentication device receives ARP packets sent by MAB user, it will authenticate the MAC
address of the MAB user and there is the corresponding authentication information in the
authentication server, the matched packets of the port and the source MAC are allowed to
pass when the authentication is successful. MAB user didn't need to input the username and
password manually in the process of authentication.
At present, MAB authentication device only supports RADIUS authentication method. There is
the selection method for the authentication username and password: use the MAC address of
the MAB user as the username and password, or the fixed username and password (all users
use the configured username and password to authenticate).
