[BUG?] New PPPoE module (if_pppoe) causes high "Errors Out" on WAN (Vivo Fibra)
-
@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).
