I wish to apologize to the list for such a simple question. I was under the gun
yesterday and it is faster sometimes to ask the list than it is to download the
FAQ and print it out.
I don't normally do that. I am usually very good about researching and trying
to find the answers myself...
I would like to thank all of the 65 people that responded with an answer to my
question. It would make for a very long post to thank them all individually, so
I wish to just thank the list in its entirety!
Here is the general tip that was given, and it serves as a reminder of
things/commands that I know, but take for granted... :)
Using the ndd command to access the hme kernel driver and change parameters on
the fly, you can change the behaviour of a specific hme device with the
following... I have created a script that runs at startup that will (until no
longer needed) change the hme interface at boot time.
Here is the basic steps that were given by 95% of the responses...
# ndd -set /dev/hme instance 0 (Change this to whatever instance of hme you
need. Mine was hme0)
# ndd -set /dev/hme adv_10hdx_cap 1 (Turns on the 10mb half duplex)
# ndd -set /dev/hme adv_100fdx_cap 0 (Turns off the 100mb full duplex)
# ndd -set /dev/hme adv_autoneg_cap 0 (This will ensure that auto-negotiation is
off)
You can confirm that the settings are implemented by using the following
commands:
# ndd -get /dev/hme link_speed (0=10mb, 1=100mb)
# ndd -get /dev/hme link_mode (0=Half Duplex, 1=Full Duplex)
The other 5% recommended that the interface be configured at the OBP with these
commands:
One of the best answers that I received (Documentation wise) was from John T.
Douglass and is as follows:
SRDB ID: 16143
SYNOPSIS: How to force the HME card to work at 10mb (full-duplex).
DETAIL DESCRIPTION:
The section "10FDX" includes how to force the HME card to work at 10 MB
(full-duplex). You can either put the commands in the /etc/system file
or in a startup script -- i.e. /etc/rc2.d/S99hme_config. You can also
make the changes from the command line -- using the "ndd" command and
the syntax below but we need to put the commands in /etc/system or a
startup script to preserve the environment accross reboots.
SOLUTION SUMMARY:
10FDX only
/etc/system
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=0
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=1
set hme:hme_adv_10hdx_cap=0
ndd commands
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_100T4_cap 0
ndd -set /dev/hme adv_100fdx_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 1
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0
