Hi ankur

U can change to full duplex thorugh lanadmin

Find out the ppa number of ur card by lanscan command.

The NMID filed in lanscan output is the ppa number for ur lancard.

To change to 1000Mbps Full duplex use

lanadmin -X 1000FD

It doesn't require a reboot and u can check the current status through sam also.
sam -->networking and communication -->network interface cards-->selct the card and check the configuration.

Regards
CS

Hi:

You will need to set HP_HP_BASET_SPEED[n]=100FD for the entry matching your HP_BASET_INTERFACE_NAME[n].

The choice of the for '/etc/rc.config.d/' is dependent on the driver you have:

btlan0 = hpeisabtconf
btlan = hpbtlanconf
btlan1 = hpbasetconf
btlan3 = hpbase100conf
btlan4 = hpgsc100conf
btlan5 = hppci100conf
btlan6 = hpsppci100conf
intl100 = hpintl100conf

You can deduce the driver from:

# ioscan -kfC lan

Hi Ankur,

I think it is a setting at the lan card level and not about the product APA. So suggestions should be all the best.

Also check the following thread where I and other guys replied about how to change the lan card sepeed:

As usual please don't forget to assign points if people helps you.

Thanks and best regards,

Hi,

First of all, you have the same settings for lan and its switch port, i.e. if the port is set up as 100HD, the lan should be set up 100HD etc. If you want to have the best performance, the setup must be 100FD.
I think, that the best way to setup the lan is to use SAM.
Please do that either from the computer console or from connection via other lan.

I think this is what you want:

[root@orasrv2:]/etc/rc.config.d<>>> more hpbase100conf
[root@orasrv2:]/etc/rc.config.d<>>> more hpbase100conf

Hi Ankur,
Consider that configuration also depend of the switch port where the lan card is connected to, it must be configured to full duplex mode also.

I think its worth noting that some early btlan cards were not capable of running FULL duplex even though they were capable of running at 100HD. At 100HD I have found that the errors, collisions and such happen too fast for the switch/router to handle and it shuts the drop down temporarily causing backups and such to fail. If your card is only capable of 100HD its better to leave it at 10HD and avoid that problem. If its running at 100FD now, you can configure at the prom level by interrupting the boot and going into CO LC "configure Lanconf" and from there type help and choose your setting, and then reboot again to pick it up
You should also configure the /etc/rc.config.d lan file for your OS level, ie 11.11 is usually hpbtlanconf. with the settings. And the previous reply was correct if you set the system you must set the switch to the same, usually requires a passwd to log into the switch. Else you can
end up with what we call a network mode mismatch resulting in a system running slower then the old 10HD would have. also evidenced by lots of runts and giant showing up on the switch when monitored.
