4.12.1 Port Limit Control
This Page allows you to configure the Port Security Limit Control system and port settings. 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.
The Limit Control module utilizes a lower-layer module, Port Security module, which manages MAC addresses learnt on the port.
The Limit Control configuration consists of two sections, a system- and a port-wide. The Port Limit Control Configuration screen
in
Figure 4-12-1
appears.
