Setting 100 Full Duplex

dictum9 — Mon, 23 Oct 2006 16:34:14 GMT

OK, here is the info. My driver is btlan.

# ioscan -kfnC lan

And here is where I manually set it. Apparently it took it, but how do I modify the above script to make this change permanent?

# lanadmin -X 100FD 0

WARNING: an incorrect setting could cause serious network problems!!!

Driver is attempting to set the new speed
Reset will take approximately 11 seconds

# lanadmin -x 0
Current Config = 100 Full-Duplex MANUAL

You don't modify that script.

You modify /etc/rc.config.d/hpbtlanconf to set the speed.

Add

HP_BTLAN_SPEED[0]=100FD

in /etc/rc.config.d/hpbtlanconf

Just as an FYI, here is the list of drivers and the appropriate file in /etc/rc.config.d to modify for that driver:

Driver File to modify
btlan /etc/rc.config.d/hpbtlanconf
btlan0 /etc/rc.config.d/hpeisabtconf
btlan1 /etc/rc.config.d/hpbasetconf
btlan3 /etc/rc.config.d/hpbase100conf
btlan4 /etc/rc.config.d/hpgsc100conf
btlan5 /etc/rc.config.d/hppci100conf
btlan6 /etc/rc.config.d/hpsppci100conf

I usually use SAM to set it.

I go with Rariasn has published.
Especialy the attention to your port
is auto-negotation off. So it is ficed port to port.

Adapting the script is permanent during each boot.

It seems you have already tested it
successfully and your lancard
supports it. So you can safely
adapt your script as shown.

This is good info, but where do you get the HP_BTLAN_interface_name[x] from? I know what lan0, lan2 is but that number in the bracket [ ]

Re: Setting 100 Full Duplex

Patrick Wallek — Tue, 24 Oct 2006 14:52:05 GMT

That is just the index number for the value triplets.

The first triplet would be index [0], the second index [1] and so on. It does not necessarily relate to the lan? interface numbers.

Do you _really_ have to go with hardcoding? The NICs driven by the btlan driver should autoneg just fine, so unless you are stuck with a hopelessly broken switch, leaving things at autoneg might be better.

Frank de Vries — Wed, 25 Oct 2006 02:35:21 GMT

What Rick is saying is the ideal situation,
and in most cases it is like that.

However, you are then dependent on your
network hardware, event when it works well,
glitches are not unthinkable.
We had the odd incident once in a while.

The most important nodes in our network
we have hardcoded through the script.
I have had no incident at all since then.

So better the devil you know then you don't.
