2-­‐14 MAC Table
Switching frames is based upon the DMAC address contained in the frame. The switch builds a table
that maps MAC addresses to switch ports to identify 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 the 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 it
does not see any frames with the corresponding SMAC address after a configurable age time.
