boot net:speed=100,duplex=full – install

This is a gem for jumpstarting, usually people have a begin script that sets the interface to 100M Full. But this sets the interface immediately at boot time. It speeds this up a bit, and makes it easier to configure your jumpstart server. For more information see EXAMPLES in boot(1m).

Setting ce driver parameters with ce.conf

I am starting to run into a situation where I need both a 100M Full Duplex set on one ce interface, but 1000M Auto Negotiate on another. To put it bluntly this is a chore. I have done it a few times over the last year, but never remember the steps. I am sure there are some descent docs out there but I have pieced this together from looking at the documentation, which was wrong at one point. What you need to do is unambiguously identify the exact PCI device to supply different parameters. Otherwise it is easy you just add the following to /platform/sun4u/kernel/drv/ce.conf:

adv_autoneg_cap=0 \
adv_1000fdx_cap=0 \
adv_1000hdx_cap=0 \
adv_100fdx_cap=1 \
adv_100hdx_cap=0 \
adv_10fdx_cap=0 \
adv_10hdx_cap=0;

Of course you can use ndd in an rcX.d script to set these parameters, but SUN is quick to point out in the documentation that it is not supported. Plus I always viewed the conf files as the best practice.

NOTE: The following should work exactly the same for bge devices
