selected action will be taken immediately.
4.6.2.1.1 Limit Control
Limit Control can restrict the number of users that can access the switch based on users’ MAC address and VLAN ID on a
per port basis. Once the number of users that wants to access the switch exceeds the specified number, a selected action
will be taken immediately.
System Configuration
Mode: Enable or disable port security limit control globally. 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.
Aging Period: If Aging Enabled is checked, then the aging period can be set up with the desired value. By default, the
aging period is set to 3600 seconds. The allowed range is 10 - 10,000,000 second.
