Static MAC addresses do not age out. When you set up static MAC address rules, you are setting static MAC addresses for a port. This may reduce the need for broadcasting. Static MAC address forwarding together with port security allows only computers in the MAC address table on a port to access the device. 8.4.5.2 MAC Address Learning This feature allows only packets with dynamically learned MAC addresses and/or configured static MAC addresses to pass through a port on ZyXEL Ethernet Switches. 222 ENC User's Guide
