32 Intel® Gigabit Ethernet Switch AXXSW1GB User Guide
• Duplex Mode — Displays the port duplex mode. This field is configurable only when
auto negotiation is disabled, and the port speed is set to 10M or 100M. This field
cannot be configured on LAGs. The possible field values are:
— Full — The interface supports transmission between the device and its link
partner in both directions simultaneously.
— Half — The interface supports transmission between the device and the client in
only one direction at a time.
• Auto Negotiation — Displays the auto negotiation status on the port. 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.
• Advertisement — Defines the auto negotiation setting the port advertises. The
possible field values are:
— Max Capability — Indicates that all port speeds and duplex mode settings are
accepted.
— 10 Half — Indicates that the port advertises for a 10 Mbps speed port and half
duplex mode setting.
— 10 Full — Indicates that the port advertises for a 10 Mbps speed port and full
duplex mode setting.
— 100 Half — Indicates that the port advertises for a 100 Mbps speed port and half
duplex mode setting.
— 100 Full — Indicates that the port advertises for a 100 Mbps speed port and full
duplex mode setting.
— 1000 Full — Indicates that the port advertises for a 1000 Mbps speed port and
full duplex mode setting.
• Back Pressure — Displays the back pressure mode on the Port. Back pressure mode
is used with half duplex mode to disable ports from receiving messages.
• Flow Control — Displays the flow control status on the port. Operates when the port
is in full duplex mode. The possible field values are:
— Enable — Enables the flow control.
— Disable — Disables the flow control.
— Auto-Negotiation — Detects the flow control and automatically configures the
highest performance mode.
• MDI/MDIX — Displays the MDI/MDIX status on 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 are matched 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:
— MDIX (Media Dependent Interface with Crossover) — Use for hubs and
switches.
— MDI (Media Dependent Interface) — Use for end stations.
— AUTO — Use to automatically detect the cable type.
