8.4.5 Port Security
Port security allows to configure the Static MAC Forwarding and MAC Address Learning features.
8.4.5.1 Static MAC Forwarding
A static MAC address is an address that has been manually entered in the MAC address table. 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.
