Figure 11-5. Negotiation Details (twisted pair results shown)
amd31.eps
A
The speed negotiated for the connection.
B
The connection's duplex configuration:
•
Half Duplex: data travels in one direction at a time.
•
Full Duplex: data travels in both directions at the same time (as with
Gigabit Ethernet).
C
Twisted pair links only:
MDI-X (medium-dependent interface crossover): The tester compensated
for a crossover cable by crossing pairs 12-36.
MDI: The tester did not compensate for a crossover cable. Either the cable
is straight-through, or the cable is a crossover and the hub or switch
crossed pairs 12-36.
D
Twisted pair links only. Yes indicates a reversed pair on the link, (such as
wires 1 and 2 crossed). Run a wire map test on the link to check the
wiring.
E
The speeds supported by the hub or switch.
F
The pairs that supply Ethernet power and an “adequate/inadequate”
rating for the power. PoE results are shown only if the Network
Connectivity w/PoE test was selected.
