3.5 Functioning of Switches
Switches analyze all incoming data packages and forward them to the port where
the corresponding destination address is located. Exceptions are the multicast
and broadcast telegrams, which are forwarded to all active ports of the switch.
For selective forwarding of the telegrams, each switch contains of an address /
port assignment table in which the assignments of the destination addresses to a
specific port of the switch are stored. The address / port mapping table is typically
generated and maintained automatically by the switch through a self-learning
process. Incoming data packages are analyzed, filtered and forwarded directly to
the appropriate port by using this assignment table based on their destination
address. The incoming data package is sent to all ports, if there is no
corresponding entry in the assignment table for a destination address. If a
destination address answers, the assignment table is complemented with this
destination address as well as the associated port.
3.6 Port Speed & Duplex Mode
After a cable is plugged into a specific port, the system uses auto negotiation to
determine the transmission mode for the new twisted pair connection:
If the connected device does not support auto negotiation or has auto negotiation
disabled, an auto sensing process is initiated to select the speed and set the
duplex mode to half duplex.
