Speed and Duplex Confi guration
Three keywords are used to control the speed and duplex confi guration. These
keywords are Speed, Duplex, and AutoNeg.
If the board uses a fi ber interface, these keywords are ignored, and the fi ber inter-
face board only links at 1000 Mbps full-duplex.
For copper-based boards, the keywords interact as follows:
The default operation is auto-negotiate. The board advertises all supported
speed and duplex combinations, and it links at the highest common speed and
duplex mode IF the link partner is set to auto-negotiate.
If Speed = 1000, limited auto-negotiation is enabled and only 1000 Mbps is
advertised (The 1000BaseT spec requires auto-negotiation.)
If Speed = 10 or 100, then both Speed and Duplex should be set. Auto-negotia-
tion is disabled, and the AutoNeg parameter is ignored. Partner SHOULD also
be forced.
The AutoNeg parameter is used when more control is required over the auto-nego-
tiation process. It should be used when you wish to control which speed and duplex
combinations are advertised during the auto-negotiation process. The parameter
