FQ_CODEL setup and now seeting packet loss on WAN_DHCPv6

IsaacFL · Sep 25, 2018, 9:13 PM

I on the new 2.4.4 Release. I set up FQ_Codel from the video. I am seeing the following on the Gateway widget.

Intermittently.

Looking in the log, I see:

kernel config_aqm Unable to configure flowset, flowset busy!

and also these:

It seems to work ok though. ??

To get the log error to go away you will need to change your "Queue Management Algorithm" You want your scheduler to be "FQ_Codel" but you can only use "Tail Drop" as the AQM. RED and GRED might work but I've never tried those.

Do I change the "Tail Drop" in the Limiter and the Queue both?

I don't know the correct answer to this, but just to add to the confusion . . . in a recent instructional video posted by jimp he sets the queue management algorithm of his limiters to CoDel:
Youtube Video

I followed that guide and it seemed to work, but I do get the "flowset busy" log entries.

That is the video I used to set it up.

I changed it to use Tail Drop on all 4 entries, and I am seeing the same log entries, but I am not able to reset all of the states right now on the firewall.

Will have to try later when the network is not in use.

I went back to the way jimp sat it up in the video, and am going to run that way for a few days. I noticed that I only see the log entries when I am running speedtests. If I am letting it run normal, I don't see any entries, so maybe that is just an artifact of the speedtests?

Also I downloaded a large file from Microsoft, and didn't see any log entries, so maybe it is supposed to work this way?

I have been following the fq_codle thread for quite some time, and the video clearly goes against what has been established in the thread. to name a few inconsistencies. ECN, Masks and AQMs.
