4.11.2 L2 Table
Switching of frames is based upon the DMAC address contained in the frame. The Managed 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.
