– Full — Indicates that the interface supports transmission between the device and the client
in both directions simultaneously.
– Half — Indicates that the interface supports transmission between the device and the client
in only one direction at a time.
• Current Duplex Mode — Displays the port current duplex mode.
• Auto Negotiation — Enables Auto Negotiation 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.
• Current Auto Negotiation — Displays the Auto Negotiation status on the port.
• Admin Advertisement — Specifies the capabilities to be advertised by the Port. The possible field
values are:
– Max Capability — Indicates that all port speeds and Duplex mode settings can be accepted.
– 10 Half — Indicates that the port is advertising a 10 mbps speed and half Duplex mode
setting.
– 10 Full — Indicates that the port is advertising a 10 mbps speed and full Duplex mode
setting.
– 100 Half — Indicates that the port is advertising a 100 mbps speed and half Duplex mode
setting.
– 100 Full — Indicates that the port is advertising a 100 mbps speed and full Duplex mode
setting.
– 1000 — Indicates that the port is advertising a 1000 mbps speed and full Duplex mode
setting.
• Current Advertisement — The port advertises its capabilities to its neighbor port to start the
negotiation process. The possible field values are those specified in the Admin Advertisement field.
• Neighbor Advertisement — The neighbor port (the port to which the selected interface is
connected) advertises its capabilities to the port to start the negotiation process. The possible values
are those specified in the Admin Advertisement field.
• Back Pressure — Enables Back Pressure mode on the port. Back Pressure mode is used with Half
Duplex mode to disable ports from receiving messages. The Back Pressure mode is configured for
ports currently in the Half Duplex mode or on LAGs.
• Current Back Pressure — Displays the Back Pressure mode on the port.
• Flow Control — Enables or disables flow control or enables the auto negotiation of flow control on
the port.
• Current Flow Control — Displays the current Flow Control setting.
