Chapter 3 Configuring Driver Parameters 41
Enabling Autonegotiation or Forced
Mode for Link Parameters With the
OpenBoot PROM
The following parameters can be configured to operate in autonegotiation or forced
mode at the OpenBoot PROM (OBP) interface:
To establish a proper link, the speed, duplex, and link-clock (1000 Mbps only)
parameters must be configured correctly between the local link and the link partner.
Both link partners must operate in either autonegotiation or forced mode for each of
the speed, duplex, and link-clock (1000 Mbps only) parameters. A value of
auto for any of these parameters configures the link to operate in autonegotiation
mode for that parameter. The absence of a parameter at the OBP prompt configures
that parameter to have a default value of auto. A value other than auto configures
the local link to operate in forced mode for that parameter.
TABLE 3-11 Local Link Network Device Parameters
Parameter Description
speed This parameter can be set to auto, 1000, 100,or10; the syntax is as follows:
• speed=auto (default)
• speed=1000
• speed=100
• speed=10
duplex This parameter can be set to auto, full,orhalf; the syntax is as follows:
• duplex=auto (default)
• duplex=full
• duplex=half
link-clock This parameter is applicable only if the speed parameter is set to 1000 or if
you are using a 1000 Mbps MMF Sun Crypto Accelerator 4000 board. The
value for this parameter must correspond to the value on the link
partner—for example, if the local link has a value of master, the link partner
must have a value of slave. This parameter can be set to master, slave,or
auto; the syntax is as follows:
• link-clock=auto (default)
• link-clock=master
• link-clock=slave
