Auto-Negotiation - Planet IFT-802T User Manual

The Industrial Media Converter scans the destination address
from the packet-header, searches the routing table provided
for the incoming port and forwards the packet, only if required.
The fast forwarding makes the media converter attractive for
connecting servers directly to the network, thereby increasing
throughput and availability. However, the media converter is
the most commonly used to segment the existing hubs, which
nearly always improve the overall performance.
Owing to the learning function of the Industrial Media Converter,
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. It confines network traffic to its respective domain,
reducing the overall load on the network.
The Industrial Media Converter performs "Store-and-Forward";
therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur

4.4 Auto-negotiation

The STP ports on the Industrial Media Converter have a 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 detecting the modes and speeds within seconds
right after both devices are connected. Both 10BASE-T and
100BASE-TX devices can connect with the port in either half- or
full-duplex mode.
