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 four different as described below.
The Limit Control module is one of a range of modules that utilizes a lower-layer module, the Port Security module, which
manages MAC addresses, learned 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.
