Which card? Which OS? In general the answer is to set the value in a file in /etc/rc.config.d. It could be hpbtlancon, hpetherconf, hpgelanconf, ... depending upon the driver associated with your card. In any event, Gigabit speed cannot be hard-set; the card must be set to autoneg in order to allow it to run at that speed.

You should use SAM -> Networking and Communications -> Networking Interface Cards

for that. You can only set autoneg (default) *or* a fixed speed.

For HPUX11.11 you can find by lanscan ID of the NIC and run

lanadmin -x ID

This shows you speed and negotiation of the NIC

As far as I know, you can not change parameters of Gigabit NIC.
100BaseT parameters can be changed by

lanadmin -X 100FD ID.

In order to write this into appropriate file, use SAM

Of course, that is what SAM uses (and using SAM to set network configurations is for wimps). Lanadmin will only make the run-time changes that will be lost upon reboot; that is why you edit the appropriate file in /etc/rc.config.d so that the rc command will call lanadmin with the options taken from your file upon boot.

Whether you can or not is rather pointless. If you can you would have to reset it every time you re-boot the machine. You would be much better off to use SAM which will update the proper config file so that the setting will survive re-boot.

You can check and see what it is set to now as follows:

# lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/8/0/0/4/0 0x00306E38E28C 0 UP lan0 snap0 1 ETHER Yes
119

Sorry - missed the last part:

# lanadmin -x 0
Speed = 1000 Full-Duplex.
Autonegotiation = On.

All HP-UX Gigabit Ethernet NICs default to autoneg and autosense, so there really shouldn't be anything you need to set, unless someone before you has hard-coded settings.
