AOC-PG-i2+ Add-on Card User’s Manual
4-8
If Speed = 10 or 100, then both Speed and Duplex should be set. Auto-negotiation 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-negotiation
process. It should be used when you wish to control which speed and duplex
combinations are advertised during the auto-negotiation process. The parameter may
be specified as either a decimal or hexadecimal value as determined by
Table 4-2
below.
Some examples of using
AutoNeg
:
modprobe e1000 AutoNeg=0x01 (Restricts autonegotiation to 10 Half)
modprobe e1000 AutoNeg=1 (Same as above)
modprobe e1000 AutoNeg=0x02 (Restricts autonegotiation to 10 Full)
modprobe e1000 AutoNeg=0x03 (Restricts autonegotiation to 10 Half or 10 Full)
modprobe e1000 AutoNeg=0x04 (Restricts autonegotiation to 100 Half)
modprobe e1000 AutoNeg=0x05 (Restricts autonegotiation to 10 Half or 100 Half)
modprobe e1000 AutoNeg=0x020 (Restricts autonegotiation to 1000 Full)
modprobe e1000 AutoNeg=32 (Same as above)
Note that when this parameter is used,
Speed
and
Duplex
must not be specified.
If the link partner is forced to a specific speed and duplex, then this parameter should
not be used. Instead, use the
Speed
and
Duplex
parameters previously mentioned to
force the adapter to the same speed and duplex.
