Chapter 4 Configuring Driver Parameters 51

▼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 TABLE4-2 for the descriptions and possible values of these parameters.
2. Set the adv-autoneg-cap parameter to 0.
When you change any ndd link parameter,a message similar to the following
appears:
Setting Parameters Using the ce.conf File
Specify the driver parameter properties on a per-devicebasis by creating a ce.conf
filein 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 Valuesand
Definitions” on page 38.
Note – Configuring the parameters by putting ndd commands in rcX.d scripts is
not supported.
