Use the undo portal free-user interface command to delete all authentication-free
users on a specified interface.
Use the undo portal free-user all command to delete all set authentication-free users.
In actual networking environments, you can configure some servers and the LAN
network devices attached to the router as authentication-free users, enabling them to
access all networks without authentication.
The authentication-free user information contains the IP address of the user and the
interface on the router to which the user is connected. Only the user whose information
fully matches the authentication-free user information can be allowed to access the
Internet without authentication.
Caution:
z In re-DHCP authentication mode, the IP address of an authentication-free user and
the primary IP address of the interface must be on the same network segment. In
direct authentication mode, the IP address of an authentication-free user and the IP
address of the interface must be on the same network segment.
z This configuration takes effect only if portal authentication is enabled on the
interface to which the authentication-free user is connected.

# Configure a portal authentication-free user, who is at 10.110.100.100 and connected
