Supposing an entry, whose MAC address is 000AEB000001 and
corresponding port number is 1, 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 static MAC address table capacity of different types of switches may be
different. Appendix C lists the difference.
4.3.4 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.
4.3.5 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
