Operates when the port is in full duplex mode.
■ Current Flow Control — Displays the current flow control status on
the port.
■ 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.
■ Current MDI/MDIX — Displays the current MDI/MDIX status on the
port.
■ LAG — Displays the LAG for which the port setting parameters are
defined.
