When the switch performs layer2 forwarding, it searches MAC ad-
dress table and VLAN table according to target MAC address of
data frame. Its purpose is to know the destination port of the data
frame forwarding.
When the switch performs Layer 3 fast forwarding, after it gets
MAC address corresponding to next-hop IP address, it also needs
to know the destination port of the packet forwarding by searching
MAC address table.

MAC Address Categories

MAC address in MAC address table on ZXR10 8900 series switch
can be classified into the following three categories:
� Dynamic MAC address
Switch learns the dynamic MAC address through data frame in
the network, and the dynamic address is deleted when aging
time is approached. When the switch port connected with the
device changes, the correspondence between MAC address in
the MAC address table and port is also changed correspond-
ingly. Dynamic MAC address disappears when the switch is
powered off and restarted and it again requires the MAC ad-
dress.
� Static MAC address
Static MAC address is generated by configuration, so it will not
be aged. No matter how the switch port connected with the
device changes, the correspondence between MAC address in
the MAC address table and port will never change. Static MAC
address will also disappear when the switch is powered off and
restarted; it has to be reconfigured.
� Permanent MAC address
Permanent MAC address is also generated by configuration, so
it will not be aged. No matter how the switch port connected
with the device changes, the correspondence between MAC ad-
dress in the MAC address table and port will never change.
Saved permanent MAC address will not disappear after the
switch is powered off and restarted.
