LIMIT C ONTROLS
Use the Port Security Limit Control Configuration page to limit the number
of users accessing a given port. A user is identified by a MAC address and
VLAN ID. If Limit Control is enabled on a port, the maximum number of
users on the port is restricted to the specified limit. If this number is
exceeded, the switch makes the specified response.

The following parameters are displayed on the Port Limit Control
Configuration page:
System Configuration
◆ Mode – Enables or disables Limit Control is globally 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 enabled, secured MAC addresses are subject to
aging as discussed under Aging Period.
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.
