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

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.
If checked, secured MAC addresses are subject to aging as discussed under
Period .
If Aging Enabled is checked, then the aging period is controlled with this input. If other
modules are using the underlying port security for securing MAC addresses, they may
have other requirements to the aging period. The underlying port security will use the
shorter requested aging period of all modules that use the functionality.
The Aging Period can be set to a number between 10 and 10,000,000 seconds.
To understand why aging may be desired, consider the following scenario: Suppose
