2-13 MAC Table
Switching of frames is based upon the DMAC address contained in the frame. The switch
builds up a table that maps MAC addresses to switch ports for knowing which ports the frames
should go to ( based upon the DMAC address in the frame ). This table contains both static
and dynamic entries. The static entries are configured by the network administrator if the
administrator wants to do a fixed mapping between the DMAC address and switch ports.
The frames also contain a MAC address ( SMAC address ), which shows the MAC address of
the equipment sending the frame. The SMAC address is used by the switch to automatically
update the MAC table with these dynamic MAC addresses. Dynamic entries are removed from
the MAC table if no frame with the corresponding SMAC address have been seen after a
configurable age time
