You inform everybody they see network change.
This will cause connectivity issue with server. Better do this at server console.
configure /etc/rc.config.d/netconf

and if you want to make 100 Full Duplex permanent then change relative file in /etc/rc.config.d
btlanconf or hpgelanconf.
Change network physical connection from lan0 to 1.
then /sbin/init.d/net stop;/sbin/init.d/net start

If you do not want to modify the files manually -

Use SAM
disable the current lan0 card
enable lan1 card with desired IP address and speed setting

move network cable from lan0 card to lan1 card

Shalom,

You absolutely do not want to use SAM for network configuration. It has a well storied history of breaking network configuration by any means possible.

Manual edit the files.

to make lan1 lan0 you need to probably renumber your hardware instance.

Hi Gene,

You can modify the /etc/rc.config.d/netconf file to change the lan0 to lan1. I use SAM to set the NIC to 100 Full Duplex.

I respectfully disagree with Mr Protter on the use of SAM for NIC changes. I use it exclusively for NIC changes(and have done so for many years) without ever having any issues as a result. In fact, I have used SAM to correct NIC issues brought on by people who thought they knew how to do the changes by editing the files.
