Port Security Limit Control Configuration Parameters:
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 Aging 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 an end-
host is connected to a 3rd party switch or hub, which in turn is connected to a port on this switch on
which Limit Control is enabled. The end-host will be allowed to forward if the limit is not exceeded. Now
suppose that the end-host logs off or powers down. If it wasn't for aging, the end-host would still take up
resources on this switch and will be allowed to forward. To overcome this situation, enable aging. With
