Sun Microsystems X1150A manual Setting Parameters Using the ce.conf File

▼To Disable Autonegotiation Mode

If your network equipment does not support autonegotiation, or if you want to specify your network speed, you can set autonegotiation to off on the ce device.

Note –Disabling autonegotiation mode can cause collisions.

1.Set the following driver parameters to the values that are described in the documentation that shipped with your link partner (for example, a switch):

■adv-1000fdx-cap

■adv-1000hdx-cap

■adv-100fdx-cap

■adv-100hdx-cap

■adv-10fdx-cap

■adv-10hdx-cap

■adv-asmpause-cap

■adv-pause-cap

See TABLE 4-2for the descriptions and possible values of these parameters.

2.Set the adv-autoneg-capparameter to 0.

#ndd -set /dev/ce adv-autoneg-cap 0

When you change any ndd link parameter, a message similar to the following appears:

xcvr addr:0x00 - link up 100 Mbps full duplex

Setting Parameters Using the ce.conf File

Specify the driver parameter properties on a per-device basis by creating a ce.conf file in the /platform/sun4u/kernel/drv directory. Use a ce.conf file when you need to set a particular parameter for a device in the system. The parameters you set are read and write parameters that are listed in “Driver Parameter Values and Definitions” on page 38.

Note –Configuring the parameters by putting ndd commands in rcX.d scripts is not supported.
