[BUG?] New PPPoE module (if_pppoe) causes high "Errors Out" on WAN (Vivo Fibra)
-
Mmm, something could be added. Though as I understand it if_pppoe actually works as expected with ALTQ. It's just that users don't expect to see the dropped packets logged as errors,

Good morning, everyone,
I'm a bit lost regarding the PPPoE issue.
Has the root cause of the errors been identified?
Also, will the fix be included via System Patches? If so, is there an estimated timeline for when that might happen?Thanks in advance!

Bom dia, pessoal!
Estou um pouco perdido em relação ao problema com o PPPoE.
Vocês já identificaram a causa desses erros?
Gostaria de saber também se o fix será incluído via System Patches — e, se sim, há alguma previsão de quando isso deve acontecer?Agradeço desde já!

@dorabiatto said in [BUG?] New PPPoE module (if_pppoe) causes high "Errors Out" on WAN (Vivo Fibra):
Has the root cause of the errors been identified?
Yes. ALTQ decides to drop packets on congestion (which is what it does, this is not a bug) and if_pppoe counts this. Again, not a bug.
Also, will the fix be included via System Patches? If so, is there an estimated timeline for when that might happen?
There is not fix because there is no bug. We are accurately counting dropped packets. Packets which we meant to drop.

What can I do to avoid having these errors here in our pfsense? Is there anything I can do or are these thousands of errors normal?
-
@dorabiatto do you use the ALTQ traffic shaper? If so just change to use the equivalent limiter instead - you will no longer have errors.
I'm not sure I agree that it is not a bug that if_pppoe shows dropped packets as errors - this wasn't the case with the old code. To me an error should not be shown if it results from expected behaviour of dropping congested packets... a better solution would be to show a separate counter for dropped packets - that would actually be useful.
-
@brookheather But is this discarding behavior normal?
Our pfsense is simple, we use it for NAT, VPN, and other simple, everyday things.
I don't think we use ALTQ
Even so, the number of Errors Out is very high.
So, what can I do to avoid having more discarded packets?
-
Check Status > Queues. If there are any queues then you're using ATLQ.
-
@stephenw10 I disabled any queues that I was using but still my problem persists. I am beginning to think that my problem although related is not the same as the one originally reported so I might create a new thread.

-
@brookheather @stephenw10 From what I understand, Errors Out happens to those who use Traffic Shaping and those who don't.
So why does Errors Out happen? Is there any way to avoid it?
-
Do you see errors on the parent interface?
You can try the dtrace commands shown in this thread and see if you're hitting some error other than
55(no buffers).
