Gigabit Uplink Web Smart Switch
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.
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.
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.
