LACP LAGG Poor Performance & Errors

stephenw10

Yes, possibly. Try disconnecting that or removing it from the lagg.

851 is not a huge number though.

VioletDragon

Errors seems to go when i remove the 4th Port, if i only assign 3 Ports it is fine i have tried different Network Cards and still the same problem. Ive tried a HP 364T on different hardware and tried different cabling still the same problem.

FreeNAS and XCP-ng has 0 errors and have the same hardware.

stephenw10

Hmm, odd.

Do you see the expected throughput when there are no errors?

VioletDragon

Nope. i am limited to only 50 to 60mbps until i enable Hardware Large Receive Offloading then i can get way over 100mbps without any issues except errors then just stacks up and internet drops out when that is enabled.

stephenw10

I assume you are enabling LRO globally. It is actually added/removed from all the interfaces involved here?

What does ifcofig -a show?

Steve

VioletDragon

Here you go.

Yeah so no LRO on any em interface or on lagg0 or any VLAN on it.

So what happens when you enable it? Which is pretty much never required normally.

How does it fail?

Steve

VioletDragon

@stephenw10 if I enable it. I get great speeds 110mbps but after so long the Internet drops out then comes back up. WAN isn't disconnecting tho but with it disabled the Internet seems fine. When it is enabled the errors are Pilling up. What do you suggest?

VioletDragon

The Errors have always happened I tried different hardware such as motherboards, cpus, ram etc and network cards but always had issues with error in and out on the Lagg.

stephenw10

Hmm, well I would first try to find why you lose the WAN. What actually happens at that point?

Is it only WAN you lose?

Steve

VioletDragon

No. Everything on the network. Can't connect to webmail on my Mail Server which is on the same network when it happens. WAN is in a Vlan on the Lagg interface.

stephenw10

OK that sounds more like it's exhausting something. mbufs maybe. That would likely be shown on the console.

It certainly should log something.

VioletDragon

I set the mbufs to 10000 as recommended on the Tuning guide. So you think I should enable LRO then look at the logs?

It is just strange when LRO is enabled the errors are just counting up.

stephenw10

mbufs should be set to 1000000 unless you have low available RAM.

Steve

VioletDragon

That is what I've done. Machine has 4gigs of RAM but only 35% is used.

stephenw10

And all NICs are still failing when LRO is enabled?

You should try to find out what's actually failing when that happens.

VioletDragon

I know it's not a hardware issue as I have tried different motherboards, with Cpus and network cards with different memory I have tried moving the Lagg ports on the switch to other ports and different cabling still the same issue.

Cool_Corona

Can you manually change the interface settings to full duplex in the GUI??

I would like to see if that makes a difference.

Run ifconfig -a afterwards

VioletDragon

i only have these options.

stephenw10

You would need to set that on the parent interfaces. And that's tricky because you can't assign them when they're in a lagg. You could only do it using ifconfig directly.

So you don't see any errors if you remove any one of the four links?

If you have 3 links in the lagg and enable LRO does it still stop responding?

Steve
