Configurable Operational Mode Parameters

The parameters in

TABLE 4-3

determine the transmit and receive speed and duplexing

capability.

TABLE 4-3

also describes the operational mode parameters and their

default values

TABLE 4-3

Operational Mode Parameters

Parameter

Description

AutoNegAdvertised

A bitmap for the speeds advertised during autonegotiation.
The adapter only autonegotiates to a speed that is
advertised. For example: AutoNegAdvertised = 4 causes
an adapter to only advertise autonegotiation at 100 Mbps,
full duplex. No other link speeds are accepted or given
during autonegotiation. AutoNegAdvertised = 47
advertises all speeds available, This is the same as using
the default setting of 0.

0 - 255

Allowed values.

4

= AutoNegAdvertised = 100 Mpbs.

0

= AutoNegAdvertised = 47 (default).

ForceSpeedDuplex

Specify the speed and duplex mode for each instance.
If you set ForceSpeedDuplex = 7,4, the e1000g0 is set to
autonegotiate and e1000g1 is set to 100 Mbps, full
duplex. Note that fiber optic ethernet adapters ignore this
setting.
Allowed values are:

1

= 10 Megabits per second, Half Duplex.

2

= 10 Megabits per second, Full Duplex.

3

= 100 Megabits per second, Half Duplex.

4

= 100 Megabits per second, Full Duplex.

7

= autonegotiate speed and duplex. (Default).
