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.
System Configuration
Mode
Indicates if Limit Control is globally enabled or disabled on the switch. If globally disabled, other modules
may still use the underlying functionality, but limit checks and corresponding actions are disabled.
