hp-pb 100 abse tx card

[MarkW_1]

When I run lanadmin -x on the ppa # the output says autonegotiate is on. In sam I cannot change that value. How can I do this?

[Patrick Wallek]

You should edit the file /etc/rc.config.d/hpbasetconf and modify the line so that it looks like the line below.

HP_BASET_SPEED[0]=100FD


That should do it for you.

Will that change the conf. from:

# lanadmin -x ppa 1
Current Speed = 100 Half-Duplex Auto-Negotiation-ON

to Auto-Negotiation-Off if I change to 100HD
in the file, or do I need to do anything else.

The entry in /etc/rc.config.d/hpbasetconf will be read the next time you reboot the machine. It will not change it immediately.

The main question is, what speed do you want the machine to be set at? Do you want it at 100 Half duplex or 100 full duplex? Decide, then put the appropiate entry (100HD or 100FD) in the conf file.

Also be sure that your switch is set for the appropriate speed and not set to auto-negotiate as well.

Then the next time you reboot, the settings will be fixed and auto-neg will be off.

Patrick,

This hp-pb card is hd only. Can I immediately change the card with lanadmin. When I use sam to change info on nw cards, the systems (HP) do not require reboots.

lanadmin -x reports the current setting and lanadmin -X will change the setting without a reboot. Howeverm if the card does not support full duplex, you'll just get an error from lanadmin when setting it to 100FD.

NOTE: 100 half-duplex *MUST* be matched on the other end (hub or switch). If not, lanadmin will show a lot of errors in the statustice display and throughput will be less than 5Mbit/sec.

Hi Mark,

When using "lanadmin -X" the option can be either a speed / duplex setting (100FD, 10HD, etc) OR auto_on. Specifying a speed / duplex setting will turn off auto-negiotiate.

The setting specified in /etc/rc.config.d/hpbasetconf is used as the lanadmin -X option when you boot. Here again, you can specify either a speed / duplex setting or auto_on.

I should point out there are several different config files in /etc/rc.config.d for NICs. The one(s) you use depends on what type NIC you have. You can determine that with ioscan -fnkC lan. See the attached doc for info on the config files.

You can run lanadmin -X "on the fly". At best, you will interrupt net traffic on the specified NIC while it re-establishes communication with the switch. At worst, it won't be able to re-establish communication.

An example: one of my servers was set with auto_on. So was the switch. They correctly negiotiated 100FD. So you'd think I could run lanadmin -X 100FD 1 (1 is the ppa#) without a problem. Wrong. The switch was still set to autoneg and could not figure out what the server was.

My point(s): be prepared to change the switch and server settings at the same time and realize the possibility exists to interrupt your network connection.

The 100 Base TX card should support 100 full-duplex. I've got one in a K460 running 11.0 that is set to full duplex and works without a problem.

# lanadmin -x ppa 2
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF
