The page includes the following fields:

System Configuration

Object Description

 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 peri

od 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 weren’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 disconnect, and the corresponding resources

are freed on the switch.

Port Configuration

The table has one row for each port on the selected switch, which are:

Object Description

 Port

The port number for which the configuration below applies.

 Mode

Controls whether Limit Control is enabled on this port. Both this and the Global

Mode must be

set to Enabled for Limit Control to be in effect. Notice that other

modules may still use the underlying port security features without enabling Limit

Control on a given port.
