Wrong duplex-mode with GBIT-SX-NIC on L-Class and HPUX11 ?

[Joachim Mangold_1]

We are using a Gigabit-SX-Nic with a HP Procurve-Switch 4000M. The switch is reporting errors; one error-source is a misconfigured duplex-mode.
Now, the switch-port is configured to auto-negotiate. The NIC we are not shure !
How can we look in which duplex-mode the NIC is running and if the mode is wrong, who can we configure the correct mode.

Hi,
The easiest would be to use sam...
otherwise you should find a config file in /etc/rc.config.d like hpgelanconf

to see:
e.g.
lanadmin -x 6
Speed = 1000 Full-Duplex.
Autonegotiation = On.

Both the Switch Port and the NIC should be manually configured to the setting you need.

Your network bods can do the switch, by using SAM you can do the NIC.

Hi,

you can find a configuration file of Gigabit lan in /etc/rc.config.d directory

" hpgelanconf "

and Look at this part and set your NIC's speed such as under example.


# HP_GELAN_SPEED Change the speed/duplexity for 1000Base-T cards
#Valid values are: 10hd 10fd 100hd 100fd auto_on


HP_GELAN_SPEED= [VALUE]


after then, you can confirm your setting value was true or wrong by lanadmin command like this,

# landadmin -x [PPA]




Have a good day!

lanadmin -x

# lanadmin -x 0 (shows current values)

# lanadmin -X 1000FD 0 (changes values to 1000 full duplex, not auto-negotiate and will issue a reset which takes 11 seconds.)

You can update the file as suggested for the next reboot.

Hi,

Below is a small sh script I named it lanspeed and placed it /usr/local/bin.

#!/usr/bin/sh
TH=/usr/sbin:/usr/bin
ppas=`lanscan | awk '$3~/^[0-9]$/{print $3}' | xargs`
for i in $ppas
do
printf "Card at PPA %s - " $i
ipa=`ifconfig lan${i} 2>/dev/null | awk '{ip=$2}END{if(ip==""){printf("Not assig
ned")}else{printf("%s ",ip)}}'`
printf "IP Address: %15s- " "$ipa"
lanadmin -x $i 2>/dev/null | awk '{$1="";printf("%s",$0)}'
echo ""
done

it prints your current conf of all your lan's.

Hope it helps,

Robert-Jan.

You can check ur interface running which mode through the command

lanadmin -x (PPA is the ur instance no. for lan Adapter like 0,1,2,3)


If you want to change the mode the apply the following command

lanadmin -X

I believe I've read here on the forums (from well respected sources) that the gigabit NICs should not be manually set: they *HAVE* to auto-negotiate! Try a search on gigabit.

Pete is essentially correct. The autonegotiate feature is pretty much a requirement for the server (it works much better than the 10 and 100 layers do). However, the switch should still be hard set to 1000 FD.

[Steven E. Protter]

Contrary to HP's 10/100 BaseT cards autonegotiate is a must for 1000 BaseT cards.

Has to be auto negotiate on the switch, and you shouldn't go through the hard coding instructions in /etc/rc.config.d/hpbtlanconf that you'll see if you run through an itrc search on this topic.

The Manual Provides the Details:

For the SX, you should auto-negotiate as mentioned above, the switch should as well.
