Hi
I want to create two (2) SQM instances. One for gaming and one for normal WEB surfing.
Gaming SQM instance is throttled down to 80% of the speeds I pay for, giving me a triple A+ in bufferbload, quality, speed. That's fine.
My problem is that if I create a new one for usual full speed WEB surfing, it gets active even though it's not ticked.
I've test it in DSL reports webpage.
My router is a TP-LINK ND1043v4 with 17.01.0-rc2.
Any help would be appreciated.
Why you don't just disable Sqm from startup when you want Web surfing?
I was hoping to create a list of instances in the future so I could test them on the fly.
Apparently there is a problem.
How did you enable/disable the instances?
sqm has an in "enabled" switch for each sqm instance in the config file /etc/config/sqm
If you set that to '0' in the config file for each sqm section, the section should stay disabled. Does it not work that way?
Edit it to be active ("1") only for that section that you currently want.
I enabled/disabled from gui. Do you mean I should try with a command from shell?
GUI should edit the same SQM config file, so it should make no difference.
But you get more exact control when you edit /etc/config/sqm from console shell, and then use "/etc/init.d/sqm restart" to get the new config activated.
I tested that and noticed something strange. I had two config sections in the SQM config file. First had enabled 1 for eth0.2 interface, while the second instance had enabled 0 for the same interface. When I then restarted SQM, it first evaluated the first block and started SQM but then found the next block that disabled it...
root@LEDE:~# /etc/init.d/sqm restart
SQM: Starting SQM script: simple.qos on eth0.2, in: 85000 Kbps, out: 10000 Kbps
SQM: simple.qos was started on eth0.2 successfully
SQM: Stopping SQM on eth0.2
/etc/config/sqm
config queue 'eth0'
option enabled '1'
option interface 'eth0.2'
option download '85000'
...
config queue 'ethkoe'
option enabled '0'
option interface 'eth0.2'
option download '85000'
...
So, I do not think that the curent startup script logic in SQM really supports multiple alternative settings blocks for the same interface. You might need to edit the interface from eth0.2 to eth0.44 (something non-existing) in the disabled block to get it properly ignored.
Thanks mate. Though it seems more like a workaround rather than a fix.
Well, this an issue we fixed in upstream sqm-scripts. But since that version contains more restructuring the quickest potential fix (you would still need to test it I only mocked this up here in the discourse editor) would be to replace /usr/lib/sqm/run.sh's content with the following:

That hopefully will make multiple sections for the same interface work. The reason for the problems is that /etc/config/sqm can be edited multiple times before being processed by /etc/init.d/sqm, so we have no certainty that what ever instances are running are in any way related to the config file. But have a look at https://github.com/tohojo/sqm-scripts/blob/master/src/run-openwrt.sh for how @tohojo solved this issue for good.
Best Regards
Thank you so much for your response @moeller0 .Keep up the good work.
Can you pls explain which part should I replace in my /usr/lib/sqm/run.sh because I'm not very good with Linux.
The red part? The green part in the code window ? The blue part ? All together ?
The screenshot is from your reply.

Or if it's easier can you upload the modified file?
Thanks
@moeller0 You can use the "Preformatted text" option in the editor menu to markup scripts or thelike.
Thanks Tmomas,
I had forgotten to do this and hence the post looked terribly confusing, sorry Sgt_Greco. I hope this is clear enough, and hopefully it will be suffiecient to copy and paste from the discourse page..
