How to tell if auto neg is on/off?

[Unix Team]

I have r380 with hP-UX 10.20 with builtin lan. I know it is 10Base-T. How do I tell what speed and Duplex it is running? lanadmin tells me the speed is 10, but I can't seem to find anything else by using SAM, or looking at config files.

Thanks,
--Craig

You can use:
# lanadmin -x 4
Current Speed = 100 Full-Duplex Auto-Negotiation-OFF

(4) is the network management ID. Or what I guess the new OS's called PPA number.

Hi Craig,

use the command lanadmin -x 0 if the card has LMID 0 (check this in lanscan output) -
I'm afraid most 10BT cards only supported half-duplex, You will note this, if lanadmin tells You something about the 'command not being supported on this hardware'

Thanks for the replies, lanadmin -x returns the following: Error: This option is not supported for this hardware.

That being the case, I'll assume it's half duplex.

thx, --Craig

I meant lanadmin -x 4 (which is the NMID) returns the error.

Craig,

lanadmin did *not* support -x in 10.2
Why don't you go into the interactive menu with *just*
lanadmin
Else you can try
lanadmin -s NMID
but I can't remember IF it gave more than just the speed.

HTH,
Jeff

Oh & remember that NMID may *not* match the PPA
By that I mean that lan2 may be NMID 4 - so check that lanscan output carefully.

Odd. That output I pasted was from a 10.20 server (That I'm sure hasn't been patched for ages, even prior to being EOL).

Hi Dave,

Yes that is.
I was looking at the 10.2 lanadmin man page on docs.hp.com - here:

https://support.hpe.com/

But the search results page doesn't give a date - just a part number for the manual - B2355-90129

My guess is there came a patch at some point that added the functionality & Craig hasn't applied it yet.

Cheers,
Jeff

Thanks to all. This is an old system with the only patching being the General Release from Sept 2001.

I just logged into for the first time today as I learned we need to move it to another site this weekend. Checking to make sure we have the network switch configured properly at the new location.

As you can see the NMID is 4.

Hi Craig,

Looking at that lanadmin output one can almost definitively state you're running HD simply due to *all* the collisions. FD connections should have no or *very* little collisions simply due to their duplex design.
And also since you have the "older" lanadmin binary it will not support checking for, or setting of, auto-negotiation which implies it's "locked in" to 10HD - which is true of all older built-ins of that model & age.

Rgds,
Jeff
