A Length of the cabling. This example shows
approximate length (
≈
). Length may be
approximate or may not be shown (
− − −
) if the
port does not produce a reflection. This occurs with
newer hubs and switches that use common-mode
termination.
Length may fluctuate or be obviously too high if the
port’s impedance fluctuates or varies from the
cable’s impedance. When in doubt, disconnect the
cable from the port to get an accurate length
measurement.
B The type of port detected:
•
10BASET , 100BASETX , 1000BASET : An Ethernet port that
communicates at 10, 100, or 1000 Mb/s (megabits per
second). Ports may support multiple speeds.
FDX indicates
a full-duplex port, which can transmit and receive data at
the same time. Speed and duplex information are reported
only for autonegotiating ports.
•
INACTIVE PORT : The port shows no electrical activity. The
port may be unused, or the device may be turned off.
•
Device : The port does not appear to be a standard
Ethernet port.
•
NP : A “next page” flag was detected in the port’s
broadcast of capabilities. In most cases, this indicates the
port has 1000BASE-T capability; however, ports made by
some manufacturers broadcast this status flag without
supporting 1000BASE-T.
C Signal direction. This example shows a port that can
transmit or receive on either pair (Auto-MDIX).
