Adapter Driver Parameters

Parameter Meaning

tx_flow_control

If link negotiation is on, a value of 1 allows the
adapter to negotiate 802.3x transmit flow control
with the device at the other end of the link. If
802.3x flow control is supported by the other
device, transmit pause packets will be respected. A
value of 0 disables transmit flow control. The
default is 0 (off).

from 0 to the number of adapters installed in the
system. The default is 0.

To check a current parameter setting, use the following command:

# ndd /dev/alt

<parameter_name>

Setting Parameters

Follow this procedure to set parameters using the ndd utility:

1. Check

the

/etc/path_to_inst

file for the instance

associated with particular devices.

2. Specify the instance for the adapter you wish to configure:

# ndd -set /dev/alt instance

<instance#>

Any subsequent ndd configuration commands will act on the
adapter with the selected instance. The adapter remains selected
until you specify a different instance.

3. Specify the configuration command using the following format:

# ndd -set /dev/alt

<parameter> <value>
