lanspeed

Hi there,

We have a problem with HPUX11 on a rp5430 server.
When we change the lanspeed in Sam to 100FD (Autoneg off)
and then connect a Fluke NetTool (see: http://www.flukenetworks.com/us/Solutions/Handheld+Network+Testers/Products.htm)
the fluke displays that autoneg is still on.
After we disabled the lan port
and the enabled it again, it may happen the autoneg is off. But not everytime.
Sam and lanadmin always show the right speed/autoneg off but not the Fluke.
Does somebody know this beavior ?

Andreas,

have you changed the mode on the network switch as well?

I don't trust SAM to do this. Much better to use lanadmin.

You may want to set the speed manually.

To check if lan is set to full duplex or not, do this:
# lanadmin -x

To set lan speed on lan0(using btlan 3 driver) for example, edit /etc/rc.config.d/hpbase100conf

and

set
HP_BASE100_INTERFACE_NAME[0]= lan0
HP_BASE100_STATION_ADDRESS[0]=
HP_BASE100_SPEED[0]=100FD

then
# /sbin/init.d/hpbase100 start

When wi did lanadmin -x 0 there was always the correct output. Something like this:
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF

But still the Fluke showed us that autoneg is on. We also checked the files in /etc/rc.config.d/hp*** if there are the correct values in there. Everything was OK.
Even a halt and restart (shutdown -h) didn't help.
Any other ideas ?

Hi,

The output from lanadmin is the right one(trustable). could you contact Fluke nettool guys

Edit /etc/rc.config.d/hpbase100cxonf

Change
HP_BASE100_SPEED[0]=YOURCHOICE

HP_BASE100_SPEED Manually set the driver's speed. Can be
# one of: 10HD, 10FD, 100HD, 100FD, auto_on

Remember [0] assumes your card number. We had an older managed switch. and before replacing it we had to also set it to the 100FD instead of Auto.

Thanks for your help. But I need to know if somebody has also seen that the lanspeed or autoneg is physicaly different than Unix shows me. I know how to change the config files and use sam or lanadmin. Problem ist that an analyzer tells me that Unix is wrong.

We have a bunch of rp5430 servers with HPUX11. The problem sometimes there, sometimes not.

If somebody knows this behavior, what can be done ?

Are you sure that the port on the switch is not set to auto-negotiate? I find it unlikely that, once properly set, would not stay that way.

Hi Pete,

The switch is according to the
measrement equipment set to 100FD, no autoneg. I got a little document from HP where
strange behaviors with lanspeed is discribed (see attachment). This doc
hrlps me. Thanks anyway
