8. MAC Address Tables
Configuration
Switching of frames is based on 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 on 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.
