which cannot be categorized to some function type.
MAC Table
The 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 has been seen after a configurable age time.
