So...connecting my new cluster of X2100s to a load balancing switch.
The switch only does 100baseT. Given my previous poor experiences with
autonegotiation in a production environment, I'm attempting to lock
the nge0 interface on the machines at 100 full duplex.
My first instinct was to set it in /kernel/drv/nge.conf and be done with it.
Unfortunately, I have been completely unsuccessful in finding any
documentation for nge.conf and have no idea what the values are for
locking speed/duplex. The closest I've come is finding an OpenSolaris
changelog stating that a bug related to setting values via nge.conf
was fixed - google seems to have let me down...
I then attempted to disable autonegotiation and set the speed/duplex I
want via a script located in /etc/rc2.d using ndd. The ndd commands in
the script are as follows:
/usr/sbin/ndd -set /dev/nge0 adv_autoneg_cap 0
/usr/sbin/ndd -set /dev/nge0 adv_1000fdx_cap 0
/usr/sbin/ndd -set /dev/nge0 adv_1000hdx_cap 0
/usr/sbin/ndd -set /dev/nge0 adv_100fdx_cap 1
/usr/sbin/ndd -set /dev/nge0 adv_100hdx_cap 0
/usr/sbin/ndd -set /dev/nge0 adv_10fdx_cap 0
/usr/sbin/ndd -set /dev/nge0 adv_10hdx_cap 0
setting the speed/duplex caps works fine, but the autoneg one at the
top fails with "Permission denied"
This disturbed me, as I'm doing all of this as root. I tried various
shots in the dark, such as downing or unplumbing the interface before
attempting to disable autoneg via ndd, to no avail
I have included output from truss on the ndd command below.
What I really want is to lock nge0 at 100fdx via nge.conf, so if
someone can point me in the right direction on what those settings
look like, I would greatly appreciate it.
If someone could tell me why I'm unable to disable autoneg via ndd,
that would work as well.
I could very well be missing a patch - I am running stock 10 update 2
Thanks!
