Using NetRain and set port speed to 100 Full Duplex

[Jim Giles]

How do i force the network speed to stay at 100 full duplex on my 10/100 NICards.

Add lines to /etc/inet.local with

/usr/sbin/lan_config -i ee0 -a 0 -s 100 -x 1

where ee0 is the name of the interface.

Hi,

what os release and what nic cards are you using?
if 5.1x you can use sysman to configure cards.

Hi,

With a netrain pair, you will have add lines to /etc/inet.local with

/usr/sbin/lan_config -i ee1 -a 0 -s 100 -x 1
/usr/sbin/lan_config -i ee3 -a 0 -s 100 -x 1

assuming your netrain pair nr0 consist of ee1 and ee3.

Alternatively you can force the port on the switch to hold at 100 and Full duplex.

hope this helps...

regards,
Orrin.

The intel cards uses autoneg by default and works fine with this settings. Be sure your switch is also configured for autoneg as required by a point-to-point connection.

If full duplex will not be selected during autoneg there seems some "incompatibilities", "timing issues" or "cable problems".

Hi Ralf,

how do you know, what cards are in use?
Are you a clairvoyant? ;-)

Thanks, I had never used the lan config command and was trying to use the ifconfig command.

[Jim Giles]

Information that I might share. The auto negotiation was not working properly for some reason, it would go to 100 but would not auto to full duplex consistently. That's why I wanted to force the setup. Maybe I didn't have something set right to enable it but...I need not worry now.

The network card I am using is COMPAQ Intel 82559 (10/100 Mbps) Ethernet Interface.

Jim,

in this case check cable type (shielded, length etc.) and be sure you have installed latest firmware on your switch.

A previous reply suggested using the lan_config command on each member of the NetRAIN set. I have never see this work and in most cases it results in errors. Rather, when using a NetRAIN set, always apply the lan_config command to the psuedo device as follows:

lan_config -i nr0 -a 0 -s 100 -x 1

If you are having problems using the lan_config command on the individual members try addressing the set instead as above.
