Parameter description:
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.
Aging Enabled:
If checked, secured MAC addresses are subject to aging as discussed under Aging Period.
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 aging enabled, a timer is started once the end-host gets secured. When the timer
expires, the switch starts looking for frames from the end-host, and if such frames are not seen within the next Aging
Period, the end-host is assumed to be disconnected, and the corresponding resources are freed on the switch.
