ndd problem

Below is the update and then the original query.

All of the interfaces for these 2 machines are fddi (I knew that) but ndd

doesn't support fddi cards (I didn't know that). These cards run at 100Mb

ONLY so checking it's link speed and auto-negotiation properties is

pointless. However, pinpointing where my problem lies is still an issue

but I guess I need a different method of analysis, and it may still be the

cards.

I have received a few replies but nothing has helped so far. Here's what

I've done and what the response was:

ndd -set /dev/nf instance 0 operation failed, Invalid argument

(if I start with 'ndd -set /dev/nf' it asks for the name to get/set, when I

enter 'instance' it asks for the value, when I tell it '0' it gives me the

error. It does the same for '1'.)

ndd -get /dev/nf "any_thing" operation failed, Invalid argument

(I've tried link_status, link_speed, link_mode, and transceiver_inuse.

Same as above if I do 'ndd -get /dev/nf'.)

dmesg | grep nf nf0 at sbus: blah blah

                         nf0 is /iommu@f/blah/blah

                         nf1 at sbus:

                         nf1 is

All of this has been done as root, not myself. I don't fare any better on

the other machine with 'pf' either.

Hello,

I am trying to find out what speed my network cards are running at on 2

machines. One is an Ultra5 and the other is a SS20. Both are running 2.6.

The SS20 is a failover for the Ultra5 which dumps to it every hour and

performance has dropped between the two.

I have nf0 and nf1 as interfaces on the SS20 and pf0 as the interface on

the Ultra5. When I do 'ndd /dev/nf link_speed' I get the following:

operation failed, Invalid argument

I get the same on the Ultra5 using 'pf'. I have no idea what type of

interface a 'nf' or 'pf' is. Nothing is set in /etc/system.

I found out about the above by searching through the archives but I found

nothing on this problem. It may be that I need to set the instance of the

'nf' interface but I don't think that is the problem in this case since it

occurs with the 'pf' interface as well and there is only one instance of

'pf'.

All help is appreciated.
