User account policies
MAC authentication supports the following user account policies:
One MAC-based user account for each user. As shown in Figure 43, the access device uses the source MAC addresses in packets as the usernames and passwords of users for MAC authentication. This policy is suitable for an insecure environment.
One shared user account for all users. You specify one username and password, which are not necessarily a MAC address, for all MAC authentication users on the access device. This policy is suitable for a secure environment. See Figure 44.
