Gig Nic card configuration

[David Hunnicutt]

I have installed a gig nic card on an HP 9000 server running Unix. The sam command will only allow you set the speed at either 10/100. How do I configure it at 1000? The card is working fine.

Hi,

GB NIC cannot fix at speed 1000, you need to set it to AUTO. if other side is a switch, you could fix the speed on there.

GOOD LUCK!

Please indicate the exact adapter number you are trying to use and your OS version and patch levels.
Is the IGELAN driver enabled?

Gigabit cards are not meant to be "hardcoded" when operating at gigabit speeds. If it is working fine, might be best to leave it well enough alone :)

If you let the setting to float rather than fixing it, which by the was is not possible for 1000mbps rate on the interface card, and letting the switch port float to autonegotiate, they will find the 1 gb speed setting. Depending on the cabling quality and switch firmware level, you may end up in half duplex mode. I have not figured it out myself yet why and when it sets to half duplex and why to full duplex as networking devices are not under my group's control to play with them. So far, it is a crapshoot for me.

David,
you can set the speed for the lan card by using the following command

lanadmin -S 1000 1 or whatever the lan PPA number it is

to check the speed you can do a
lanadmin -s 1
for lan1

thanks

Hi David ,

You can check the current speed by ,

1. #lanadmin -s 0 [ assuming PPA no. is 0]

( PPA no, can be found by #lanscan command)

To change.

2. #lanadmin -S 1000 0

You can try this , Hope this will work ,

Cheers ,
Raj.

We've had this exactproblem as well, especially with Enterasys switches. It seems from our troubles with it that the NIC goes through some re-negotiation at some point and steps down to half-duplex after a while. Its really frustrating. Our fix for it has been to hard code the switch ports to fullduplex as its the only way to stop them re-negotiating the settings.

Thanks to everyone for their help. I was able to use your advice to solve the problem.
