Changing token ring speed on HP9000

[Arnold Perez]

I'm converting a small token ring infrastructure from 4M to 16M and we've experienced a problem with changing the speed on three 9000 servers. The sysadmin inherited the environment and only knows of one file called "hptokenringconf" (or something to that effect) where speed is a parameter. Modifying it has not helped. We still see a speed discrepency on the network equipment and we also see a quick message during boot sequence that the token ring card failed to initialize.
I suspect something else at a lower level in the stack needs to be modified but don't know where to look. The card has know switches that we can see. Any hints? Sorry I don't have more specifics. I can't take down the boxes to inspect the hardware closer.

Hi,

You can use the lanadmin command to change the speed setting. Do note that any change using this would be temporary and you need to modify the proper configuration file to make the change permanent.

Here is a link from hp docs site which will help you in configuring the token ring card. Is this card PCI or EISA,

Look for "configuring Token Ring"

Hope this helps.

Thanks Sanjay. You provided a good starting point.
That's what I needed.
Thanks again.

Hi Arnold,

I don't use token ring card myself, but wish you good luck in configuring the card. Hope you configure it the way you want. Do remeber if it is a EISA card, you will have to run the eisa config to configure the card and you'll need a reboot of the system for the change to take effect. If the card is PCI, you can use lanadmin command to change the settings on the card. To make the change permanent, modify the required file and reboot. However you can check different setting by using lanadmin command and modifying different parameter for the card.

You can get the NM_ID or the ppa for the card by using the lanscan command.

Hope this helps.
