Shalom,

It depends on the system.

/etc/rc.config.d/hpbtlanconf

Is a place you can hardcode the speed.

Hi,

# lanscan

# lanadmin -X 100FD "ppa number"

permanent change

edit the corresponding configuration file in the /etc/rc.config.d/ directory (attachment).

Hi,
You can use sam or lanadmin to configure...
To set permanently would be in a file in /etc/rc.config.d and depends on your car model...

i have lan0 so is it going to be "lanadmin -X 100FD 0 " .

Thanks

[Victor BERRIDGE]

exactly...
But you could also go interactively by typing lanadmin to see and test...
after entering lanadmin, if you type display, it will show you the PPA number, the driver and speed...


All the best

hello thank you all.
I have only one more clarification, thanks for your time in advance.
Here is the parameters specified in the hpbtlanconf of my server
HP_BTLAN_INTERFACE_NAME[0]=lan0
HP_BTLAN_STATION_ADDRESS[0]=?
HP_BTLAN_SPEED[0]=100FD
HP_BTLAN_MTU[0]=?

Not sure what should i specify for station address and mtu.please advice.
thanks

Hi,

you don't need to specify this.
Let it empty.

Hi,

HP_BTLAN_INTERFACE_NAME[0]=lan0
HP_BTLAN_STATION_ADDRESS[0]=
HP_BTLAN_SPEED[0]=100FD
HP_BTLAN_MTU[0]=1500

You can set HP_BTLAN_STATION_ADDRESS empty, the hardware(MAC) address will be automatically set after a reboot.

Thanks much for you all.

You might want to check with your network admin to make sure that your NIC settings corresponds with the settings on your HUB/ Switch.

hello ,
Thanks for all your replies , were really helpful .
How do i set the autoneg on on the server , it turned off by itself.
thanks again

[Sheriff Andy]

Just like Robert-Jan suggested.

# lanadmin -X 100FD 100 1

[subhashni]

Thank you for the reply.Actually the "lanadmin -X 100FD 1" changes the network speed as 100FD but autoneg is still off. please advice.

[Bill Hassell]

When you select 100FD, you have turned off auto-negotiation. Auto-negotiation means that the LAN card and the switch will negotiate the speed and duplex setting. Note that 100 BaseT network cards have difficulty negotiating correctly when the LAN cable is about 30-40 meters in length. In this case, the speed will usually be 100 but duplex will be half and will cause numerous errors. By editing the config file to select 100FD, the speed and duplex will be fixed and no mistake will be made.

[subhashni]

Bill,
Then the network switch should also hardcoded to 100FD ,right. so that there is no negosiation. speed and duplex set to 100 FD.

thank you for all your help.
