LAN problem

Ron Irving — Tue, 21 Apr 2009 14:46:22 GMT

lanadmin -x 1 shows 100BaseT.

Sam shows lan1 at 1000BaseT

How do I make A=B?

Are you sure they are the same NIC? What does lanscan show?

Same NIC. A7012A

Sorry, that was probably a pretty silly question.

In order to get 1000BaseT, both ends of the link are supposed to be set to AUTO. Can you verify?

Auto Neg is set to on, on my end. Infrastructure says it's on, on the switch end too.

Can you please post the full output of your lanadmin command?

Re: LAN problem

Ron Irving — Tue, 21 Apr 2009 15:12:35 GMT

lanadmin -g 1

Sorry, I meant just the full output of the 'lanadmin -x 1'.

So the autoneg results in 100 MB/s; the solution must be found at the switch side ... is it autoneg too or a fixed speed?

Re: LAN problem

Ron Irving — Tue, 21 Apr 2009 15:52:38 GMT

According to the network dude, it's set for auto negotiate. If this were the case, then I could not run ladadmin -S 1000000000, correct?

Hi,

There are few other things you need to check?

Is there any other device which doesnot support autoneg involved in between the switch and lan interface? Like hub or bridge.

Cable also should support 1000Mbps. otherwise you will not get 1000Mbps speed.

Our infrastructure team, and I changed cables, and ports on the switch...same result.

Re: LAN problem

Ron Irving — Wed, 22 Apr 2009 11:15:20 GMT

no hub or bridge between either.

Hi Ron,

Could you post the output of;

# what /stand/vmunix | grep iether

Hi,

I am still doubting switch side settings. If you are sure that this card is 1000BaseT and autoneg is ON, try to use the port which is working in 1000Mbps in your environment.

Re: LAN problem

Ron Irving — Wed, 22 Apr 2009 11:27:43 GMT

Well...my network guy is adament on this issue. He is positive it's at 1000BaseT.

Here's the output of the iether

I've got a network guy just like him! ;^)

Is there another server with a properly functioning GB NIC? Can you sneak into the switch room and connect this server to the port that is properly functioning? Or can you diplomatically ask him to show you the proof that this port is, indeed, set to auto-negotiate.

If the port is set properly, then the only other cause has to be between the port and the NIC and if there's no other hardware, then it has to be cabling. The next step is swapping out cables.

During the day it would take a Presidential decree, or an amendment to the constitution to move switch ports. Developers and the business community would be outside my door with torches and pitchforks. No sense of humour.

Our next maintenance window is 5/16, so we'll just have to limp along until then, or until I can get a 'special-window'.

I was just seeing if there was anything I could do ahead of that.
