Status: Select the status of Port Security. Three kinds of status can be selected: Drop: When the number of learned MAC addresses reaches the limit, the port will stop learning and discard the packets with the MAC addresses that have not been learned. Forward: When the number of learned MAC addresses reaches the limit, the port will stop learning but send the packets with the MAC addresses that have not been learned. Disable: The number limit on the port is not effective, and the maximum number of learned MAC addresses is limited by the length of MAC address table. It is the default setting.
