GS700AT Smart Switch Software Administration Manual
• Duplex Mode – Select the port duplex mode. This field is configurable only when auto
negotiation is disabled and the port speed is set to 10M or 100M. The possible field values
are:
– Half – The interface supports transmission between the device and the client in only
one direction at a time.
– Full – The interface supports transmission between the device and its link partner in
both directions simultaneously.
– Auto – The interface supports transmission between the device and the link partner
based on the transmission mode of the link partner.
• Auto Negotiation – Select the port auto negotiation status. Auto negotiation is a protocol
between two link partners that enables a port to advertise its transmission rate, duplex
mode, and flow control abilities to its partner. The possible field values are:
– Enable – Enable auto negotiation.
– Disable – Disable auto negotiation.
• Back Pressure – Select the back pressure mode of the Port. Back Pressure mode is used
with half duplex mode to disable ports from receiving messages. Back Pressure mode is
disabled by default. The possible field values are:
– Enable – Enable back pressure mode.
– Disable – Disable back pressure mode.
• Flow Control – Select the flow control status of the port. Operates when the port is in full
duplex mode. Flow control is disabled by default. The possible field values are:
– Enable – Enable flow control.
– Disable – Disable Flow control.
• MDI/MDIX – Select the MDI/MDIX status of the port. Hubs and switches are
deliberately wired opposite the way end stations are wired, so that when a hub or switch is
connected to an end station, a straight through Ethernet cable can be used and the pairs
will match up properly. When two hubs or switches are connected to each other or two end
stations are connected to each other, a crossover cable is used to ensure that the correct
pairs are connected. The possible field values are:
– Auto – Provide automatic cable type detection.
– MDI (Media Dependent Interface) – Connect end stations.
– MDIX (Media Dependent Interface with Crossover) – Connect HUBs and switches.
