Due to the learning function of the Ethernet switching, the source address
and corresponding port number of each incoming and outgoing packet
are stored in a routing table. This information is subsequently used to filter
packets whose destination address is on the same segment as the source
address. This confines the network traffic to its respective domain, reducing
the overall load on the network.
The Switch performs "Store and Forward" therefore, no error packets occur.
More reliably, it reduces the re-transmission rate. No packet loss will occur.
3.5 Auto-Negotiation
The STP ports on the Switch have built-in “Auto-negotiation”. This technology
automatically sets the best possible bandwidth when a connection is
established with another network device (usually at Power On or Reset).
This is done by detect the modes and speeds at the second of both device
is connected and capable of, both 10Base-T and 100Base-TX devices can
connect with the port in either Half- or Full-Duplex mode.
