Chapter 3 Configuring Driver Parameters 25
Advertised Link Parameters
The following parameters determine the transmit and receive speed and duplex
link parameters to be advertised by the vca driver to its link partner.
TABLE 3-2
describes the operational mode parameters and their default values.
Note – If a parameter’s initial setting is 0, it cannot be changed. If you try to change
an initial setting of 0, it will revert back to 0. By default, these parameters are set to
the capabilities of the vca device.
