Authentication Server) statistics only. Use the port select box to select which port details to be
displayed.
The page shows the Port State information including the parameters Admin State, Port State, QoS

3.12.6 Port Security
3.12.6.1 Port Limit Control
Limit Control allows for limiting the number of users on a given port. A user is identified by a MAC
address and VLAN ID. If Limit Control is enabled on a port, the limit specifies the maximum number
of users on the port. If this number is exceeded, an action is taken. The action can be one of the four
different actions as described below.
