Dual Speed Functionality And Switching; Switching, Filtering, And Forwarding - Moxa Technologies EtherDevice Hardware Installation Manual

Dual Speed Functionality and Switching

Moxa EtherDevice Server's 10/100 Mbps RJ45 switched ports can
be configured for 10 Mbps operation, 100 Mbps operation, or to
auto-negotiate with the connected device for the fastest data
transmission rate supported by both devices.
All models of Moxa EtherDevice Server are plug-and-play devices,
so that software configuration is not required at installation, or
during maintenance. The half/full duplex mode for the switched
RJ45 ports is user dependent and changes (by auto-negotiation) to
full or half duplex, depending on which transmission speed is
supported by the attached device.

Switching, Filtering, and Forwarding

Each time a packet arrives at one of the switched ports, a decision
is made to either filter or forward the packet. Packets with source
and destination addresses belonging to the same port segment will
be filtered, constraining those packets to one port, and relieving the
rest of the network from the need to process them. A packet with
destination address on another port segment will be forwarded to
the appropriate port, and will not be sent to the other ports where it
is not needed. Packets that are used in maintaining the operation
of the network (such as the occasional multi-cast packet) are
forwarded to all ports.
Moxa EtherDevice Server operates in the store-and-forward
switching mode, which eliminates bad packets and enables peak
performance to be achieved when there is heavy traffic on the
network.
