TABLE 8 Read-Only Link Partner Capabilities (Continued)

Parameter

Description

 

 

 

lp_1000hdx_cap

0

= No 1000 Mbits/sec half duplex transmission

 

1

= 1000 Mbits/sec half duplex

lp_asm_dir_cap

0

= Not Asymmetric Pause capable

 

1

= Asymmetric Pause toward link partner capability

lp_pause_cap

0

= Not Symmetric Pause capable

 

1

= Symmetric Pause capable

 

 

 

If the link partner is not capable of autonegotiation (when lp_1000autoneg_cap is

0)the remaining information described in TABLE 8 is not relevant and the parameter value = 0.

If the link partner is capable of autonegotiation (when lp_autoneg_cap is 1), the speed and mode information is displayed when you use autonegotiation and get the link partner capabilities.

Setting ge Driver Parameters

You can set the ge driver parameters in two ways, depending on your needs:

■Using the ndd utility

■Using the ge.conf file

Use the ndd utility to set parameters that are valid until you reboot the system. It is also a good way to test parameter settings.

Use the ge.conf file to set parameters so they remain in effect after you reboot the system. Create a /kernel/drv/ge.conf file and add parameter values to this file when you need to set a particular parameter for a device in the system.

Setting Parameters Using the ndd Utility

Use the ndd utility to configure parameters that are valid until you reboot the system. The ndd utility supports any networking driver that implements the Data Link Provider Interface (DLPI).

The following sections describe how you can use the ge driver and the ndd utility to modify (with the -setoption) or display (without the -setoption) the parameters for each ge device.
