555555 Static MAC Address Table
A static MAC address table entry contains a MAC address and its corresponding switch port. All the packets taking that MAC address as their destination will be forwarded to the corresponding switch port.
The static MAC address won’t age, which differs from the dynamic MAC address. The static MAC address table entry is always valid before it is deleted.
Supposing an entry, whose MAC address is 000AEB000001 and corresponding port number is 1 and it is added to the static MAC address table. All the packets routing to the address of 000AEB000001 egress for the switch port 1. This static entry obliges the device of 000AEB000001 to be connected to port 1; otherwise, that device cannot be accessed. Static MAC addresses are free of MAC learning, which enhances the efficiency of packets forwarding. The MAC addresses already configured in static MAC address table cannot be added to filtering MAC address table.
The capacity of static MAC address table capacity differs among different switches. Appendix C lists the difference.
555555 Filtering MAC Address Table
A filtering MAC address excludes a device from being accessed through the switch. All the packets taking the filtering MAC address as their destination will be discarded. The filtering MAC address is applicable to all the switch ports. The configured filtering MAC address can neither be added to static MAC address table, nor be bound by switch ports.
555555 Dynamic Binding
A switch port in dynamic binding state can bind a specified number of MAC address. Once the specified number is reached, the port transfers into secure state automatically and stops binding MAC addresses. The bound MAC addresses won’t age, they can be removed by disabling the dynamic binding or rebooting the switch.
The function of dynamic binding causes the switch port to acknowledge the devices connecting to it after startup, and stores the connections (through binding MAC addresses\ in static state. This enhances the efficiency of packets forwarding and limits the connecting device number of the switch port. Reboot the switch after configuring the dynamic binding function. The switch will acknowledge and bind the latest connecting devices. If the switch is managed through remote connection, please add the MAC address of the management computer or that of the default gateway to the static MAC address table; otherwise, the management channel may break down.
