Network card speed settings

[BFA6]

Hi,

Is there a quick way of finding out if the network cards in my servers, can run at 100mb ?

regards,

Hilary

see the command lanadmin with the option -x.

Hi

To check your cards capability:
# lanadmin
Enter Command: lan
Enter Command: display

"Description" will give you the type card:
10/100TX Full-Duplex

means that yo can run this card at 10 or 100 Mb and half or full duplex.

Remember that the settings on your crad must match the switch settings, and if the switch is set to Autonegotiate, so must your card.

Andreas,

I've run lanadmin and get the following

lan0 Hewlett-Packard LAN Interface Hw Rev 0

Does this mean that this card can only run at 10mb ?

Thanks,

Hilary

run the command lanscan
the output gives all lancards and you can see the NM-ID for each card.

then you can run lanadmin -x NMID and the output shows you the speed of the card, e.g. 100 Full Duplex.

sorry, you need the value "Card IN" from the output of lanscan for the lanadmin -x command, not the NMID.

Hi,

But will lanadmin show me the speed the card is capable at running at ?

I have the cards set to 10mb, but I need to know if they are capable of running at 100mb

You can change the speed settings with:

lanadmin -X CardIn 100FD

if the card cannot be switched it will give an error message.
btw, what does the output ioscan say about your lancard?

Hi

Christians reply will give you the current setting, but I guess you'll want the upper limit?

Andreas

[BFA6]

Andreas,

Yes please, I need to know the upper limit.

HI again

I think you will have to consult the Owners Guide for your server system:

http://docs.hp.com/hpux/hw/index.html

There you find the Core I/O that is in the system.

ioscan -funC lan should give you something like that:

lan 1 8/0/20/0 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX Core

[BFA6]

Hi,

ioscan gives the following

lan 0 8/16/6 lan2 CLAIMED INTERFACE Built-in LAN

Hilary,

I assume by the ioscan output that this is a D-Class server. The inbuilt lan is only capable of 10HD speed. Now if you want to purchase a card that will run 10/100 HD/FD I would recommend the J3515A single port lan card or J3516A dual port card. Both cards use the btlan4 driver.
