4.2.30 Configuring Port-based
Single-user Authentication
By default, 802.1x controls on the basis of user MAC. Only the authenticated users can use
the network, while other users connected to the same port is not able to use the network. In the
port-based control mode, the port is authenticated when there is an authenticated user on the
port. All the users connected to the authenticated port are able to use the network normally.
However, in the port-based control mode, the port-based single-user authentication controls
only one authenticated user. The port is authenticated when it allows only one authenticated
user who is enable to use the network normally. Then, if you find other users on the port, you
should clear all the users on the port and reauthenticate.
From the privileged mode, follow the steps below to configure port-based single-user control
mode on the port.
