In original design, port security function will stop learning MAC addresses when it reaches a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static address table will be accepted.
If enable network-access aging then the switch's secure MAC address table will be removed when the aging time expires or detect the MAC address on new ports.
So we enhance Sticky MAC function on ECS4620 series. When you connect the interface to your network, you can enable the sticky MAC feature and ensure that MAC-address is only learned on this port and protect MAC-address is not learned by other ports even port move or any attack.
