changing built in lan on C200 to 100 full duplex

[Joe Swauger]

I have a customer who has the following problem: The model is a C200, it does have the lan aui in the back. sticker on backside near the rj45 port says 10bt/100btx. Want to ideally have it run at 100/full,half, auto. The exact error message when using sam to try to change those settings is
"The driver specific configuration file in /etc/rc.config.d dosent support the configuration of speed, duplex, and autoneogotiation from /usr/newconfig/etc/rc.config.d directory. to enable this contact your support personnel for further assistance"

Any ideas would be appreciated. thanks

You need to do two things to make sure it runs 100 BT full duplex.

hard code this settng in the file /etc/rc.config.d/hpbtlanconf

Then make sure the switch is set manually for 100 BaseT Manual.

Sorry,

I forgot to explain that HP 100 BT cards don't work well with auto negotiate.

You can change settings with the lanadmin -X command. landadmin -x shows current settings.

On our machine in the /etc/rc.confid.d directory there is no hpbtlanconf file.
there is hpbase100conf and hpetherconf. neither of which have any settings defined.
If i use the hpbase100conf file and set it to lan0, will it then be assumed the card is going to run at 100mb? reason i ask is because the file contains the interface name, station address fields but the last setting is only duplex, doesnt address speed at all.

by the way this machine is running HPUX10.20

Hi Joe,

Have you tried the Lanconfig (LC) command from the CO menu. you access the CO menu by interrupting the boot process and typing "CO" and the prompt. Return to the main menu from the CO menu by typing "MA".

hope this helps.

ioscan -fkC lan will display the btlan driver loaded in the kernel.

Not it and accordingly modify the file in
/etc/rc.config.d/

Driver File
btlan0 hpeisabtconf
btlan hpbtlanconf
btlan1 hpbasetconf
btlan3 hpbase100conf
btlan4 hpgsc100conf
btlan5 hppci100conf
btlan6 hpsppci100conf

If you want to use sam to do it, it sounds as if you need to load a sam patch.

#lanscan
>> note the NMID of the card

#lanadmin -x NMID
>> will show the current speed/duplex

#lanadmin -X NMID 100FD
>> will change it on the fly

(ensure the port on the switch is set to 100FD)

Modify the appropriate configuration file in /etc/rc.config.d to set upon reboot.

Joe the C200 can be set at the boot admin menu.

Here is the procedure:
'LanConfig AUTO' Command Information

HP 9000 Workstatation models B132L+, B180L, C200, C240, C360 and
J2240 have an Automatic Lan Configure feature. The 'Default'
setting is 'LanConfig AUTO' which searches for the LAN-TP(RJ45)
first. If that setting fails, the system tries the LAN-AUI
setting next.

NOTE: Any LAN Configuration changes will take effect at the next
Boot or SEArch command.


The LanConfig command (at the Boot Console Interface) configures
and displays the current LAN settings.

Accessing the LanConfig command at the Boot Console Interface:

1. Boot the system:

* If AUTOBOOT is turned off , the boot sequence automatically
stops at the boot console main menu.

* If AUTOBOOT is turned on, you will see the following message:

Processor is starting Autoboot process.
To discontinue press any key within 10 seconds

* If AUTOBOOT and AUTOSEARCH are both turned on, you will see the
following message:

Processor is booting from first available device.
To discontinue press any key within 10 seconds.

NOTE:If you are using power-saving Monitor, you will have
less than 10 seconds from the time this message appears to
press a key.

2. Press a key.
You will see the message:

Boot terminated

The Main Menu of the boot console appears.

Main Menu: Enter Command >

3. Type in CO for configuration commands:

Configuration Menu (CO)

4. At the Configuration Menu prompt, Enter the appropriate
LanConfig command to achieve the desired configuration. The
next section lists the available commands.

----------------------------------------------------------------------
LanConfig Commands

To enable/disable the built-in LAN, enter the following command:

LanConfig [ENABLE|DISABLE]

To set the different speeds and operation modes, apply one of the
following LanConfig commands at the Configuration Menu: Enter
command> prompt:

* To automatically select the network speed (100 Mbytes/sec or
10 Mbytes/sec) and data transfer operation (full or half duplex),
operating in compliance with IEEE 802.3u, type the following:

LanConfig AUTO_detect

* To select 10 Mbits/sec network speed and half duplex mode, type
the following:

LanConfig 10/Half_dx

* To select 10 Mbits/sec network speed and full duplex mode, type
the following:

LanConfig 10/Full_dx

* To select 100 Mbits/sec network speed and half duplex mode, type
the following:

LanConfig 100/Half_dx

* To select 100 Mbits/sec network speed and full duplex mode, type
the following:

LanConfig 100/Full_dx

* To select the AUI port (10 Mbits/sec, half duplex only), type
the following:

LanConfig AUI

The LAN setting defaults to LAN-TP(RJ45). If that setting fails,
the system tries the LAN-AUI setting. The new LAN configuration
settings take effect at the next BOot or SEArch command.

NOTE: Short command for LanConfig is LC.

Hope that helps,

Todd

Thanks for all the responses. the customer was able to set it via the LC command at the config menu during boot. thanks again fo all the great responses.
