17.1 Legacy Series / Re: guide to using fq_codel on 17.1

« on: March 02, 2017, 03:31:04 am »

Your screenshots gave me an idea. I had followed the example from RickNY that I linked in an earlier post in this thread. In that example, I created my queues WITHOUT checking the Enable CoDel box.

I noticed your screenshots had that box checked. I checked that box on both of my queues and I now also show aqm codel listed in the status. It would appear as though checking the Enable CoDel box in the Pipe configuration doesn't have an effect, it has to be selected in the queue configuration.

My connection is asynchronous 120/10, I had to create two pipes (limiters) to segment my queues and rules to respect the bandwidth limits.

Limiters:
10000: 115.000 Mbit/s    0 ms burst 0
q75536  50 sl. 0 flows (1 buckets) sched 10000 weight 0 lmax 0 pri 0 droptail
 sched 75536 type FIFO flags 0x0 0 buckets 0 active
10001:   9.700 Mbit/s    0 ms burst 0
q75537  50 sl. 0 flows (1 buckets) sched 10001 weight 0 lmax 0 pri 0 droptail
 sched 75537 type FIFO flags 0x0 0 buckets 0 active


Queues:
q10000  50 sl. 0 flows (1 buckets) sched 10000 weight 100 lmax 0 pri 0  AQM CoDel target 5ms interval 100ms NoECN
q10001  50 sl. 0 flows (1 buckets) sched 10001 weight 100 lmax 0 pri 0  AQM CoDel target 5ms interval 100ms NoECN

I'm using the latest version 17.1.2. I actually just reloaded it on another box and manually re-applied all the settings based on the links above. Here is what I see in the log file after creating the pipes/queues/rules.

Mar 1 15:20:08   kernel: load_dn_aqm dn_aqm PIE loaded

Mar 1 15:20:08   kernel: ipfw2 (+ipv6) initialized, divert loadable, nat loadable, default to accept, logging disabled

I'm only selecting fq_codel when I create the pipe and input the bandwidth value in kbits. I don't select any other fq_codel components when creating the queues or the rules. I follow RickNY's instructions to the letter and it seems to work to manage buffer bloat. With these disabled, I get bad buffer bloat. When I follow RickNY's steps I get an A+ rating on the same DSLreports test.

I'm not sure why it isn't working for you. I was able to successfully duplicate these settings on two different boxes. For what it's worth, I'm using newer Intel quad port cards with the igb driver. Not sure if that matters or not.

Yes, I was confused by this too (partly why I posted here asking for help). Based on the links above, I just left all the defaults in place and/or left the sections blank. I think that's why some of my status information appears to be so limited.

Attached is a detailed screenshot of how I have one of the downpipes configured. All I can say would be to try it and run some bufferbloat tests and check if you are seeing an improvement. In my case, with these settings, I am seeing an improvement in the bufferbloat tests.

I wish some of this had better documentation as I still find it confusing and I'm just doing trial and error to see if it's working.

I have not experienced the issue outlined in that Github link. However, I am trying to do something very simple with very few queues/pipes. I'm basically just trying to duplicate what IPFire and OpenWRT already do with their fq_codel bandwidth controls. I prefer a BSD based firewall because I think pf is a better technical solution to the problem and I think that the OPNsense community is more active. So I was only trying to duplicate that very simple goal.

I've attached some screenshots of my config. I'm using the DSLreports test to confirm that buffer bloat is being controlled. I am using this to ASSume that the fq_codel is working because I see the same results if I run the same DSLreports test with IPfire and it's own fq_codel enabled. I hope this helps. I can post additional screen grabs of my config if necessary.

For the information of people that may be looking for the same thing, I was able to get this working successfully on OPNsense 17.1 by searching the forums for the OPNsense 16.7 series that introduced the fq_codel functionality.

I used the below threads to setup a simple fq_codel pipe and get a "knob-less" QoS implemented on OPNsense 17.1. It seems to be working quite well so far.

17.1 Legacy Series / guide to using fq_codel on 17.1

« on: February 28, 2017, 07:44:57 pm »

Hello and first post for me! Love the software and great work by this community on OPNsense! I was excited to see that fq_codel is available in 17.1 however, I can't figure out how to get this working.

Is there a guide available or a walkthrough on how to use fq_codel in OPNsense?
