•
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.
•
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.
•
MDI/MDIX — Displays the Media Dependent Interface (MDI)/Media Dependent Interface
with Crossover (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 — Use for hubs and switches.
–
Auto — Use to automatically detect the cable type.
–
MDI — Use for end stations.
•
Current MDI/MDIX — Displays the current MDI/MDIX setting.
•
LAG — Defines if the port is part of a Link Aggregation (LAG).
•
PVE — Indicates that this port is protected by an uplink, so that the forwarding decisions are
overwritten by those of the port that protects it.
