Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IESH-MB’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, without
paying attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or cross-over cable to connect the IESH-MB to Ethernet devices.
Triple Speed Functionality and Switching
The IESH-MB’s 10/100/1000 Mbps RJ45 switch port auto negotiates
with the connected device for the fastest data transmission rate
supported by both devices. The IESH-MB is a plug-and-play device, so
software configuration is not required at installation or during
maintenance.
The half/full duplex mode for the RJ45 switched 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 a 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 except
the incoming port. The IESH-MB 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.
