Changing network card to full duplex

[Aaron Tebo]

How can you change the network card on a HP9000/D370 to full duplex? It is using OS ver 10.2

[Stefan Farrelly]

edit the file /etc/rc.config.d/hpsppci100conf and change the line;
HP_SPPCI100_DUPLEX[0]=FULL

and reboot your server. You will need to ensure the network device it connects to (hub/switch) also has full duplex set on the port its plugged into.

Depending on what 100Mb network card you have this file may be called something slightly different, but it should have a 100 in its name. Do a>
grep -i duplex /etc/rc.config.d/* and you will see the file you need to edit.

To change the settings on a NIC use the lanadmin command with the "-X" switch. You can check the current settings with the "-x" switch.

[Rick Garland]

The lanadmin -X command will change the duplex settings. Ensure you are patch.
A common return to the command is "hardware not supported for this option". This will go away if you are patched. Depending on the drivers in use will depend on the patches you need.

[Alan Riggs]

lanadmin -X 100FD
will work until reboot. The instance number can be found from lanscan.

To make the change permanent, edit the appropriate configuration file and set the speed/duplex setting. The configuration file will differ depending upon which type of NIC you have (HPPB, HSC, EISA). It will be found in /etc/rc.config.d and will have a form like "hpbase100conf" or "hpeisabtconf".
