Hi.

On 6.0, Winbox does not show queue trees after making a change, but the Terminal does. This was not an issue in the 6.0 RC11 version the CCR shipped with as far as i know.. Any advice on this?

Just to make sure:

'global-in', 'global-out', or 'global-total' are replaced with 'global' in v6

today i updated my CCR1016-12G to version6.1 . The bug is not fixed yet.

atu · Thu Jun 13, 2013 6:11 am

what exactly is not working for you? please explain in details what you expect and what you see

sry for my poor english.

2 WAN named:WAN_CNC and WAN_TEL
1 LAN named:ether6_LAN

in mangle, i marked conn for P2P,Games etc... then marked packets upload/download like game_down_cnc,game_up_cnc,small_down_tel.. etc
u can see the Bytes/Packets counters are working fine and numbers is changing in mangle, but in queue tree with packet mark, they don't work at same time (packet counter read 0),only 1 of quere trees has packets reading at same time in winbox .

i attached mangle and queue tree,plz hlp me . those setting is working good in version 3.xx~5.xx

all your queues in Queue Tree are disabled - is it normal?..

atu · Sat Jun 15, 2013 9:12 am

all your queues in Queue Tree are disabled - is it normal?..

because they can not work,so i disabled them.

Chupaka · Sun Jun 16, 2013 7:26 pm

because they can not work,so i disabled them.

I don't understand... is it working better when they are disabled?.. because all screenshots and all configs you show do not expose anything unusual - when queues are disabled, they don't work

Funny question and perception.

What he means is he disabled it because it didn't work. If you want to try it, just simply copy the config and enabled it.

Almost same situation also for me.
CCR router, with v6.1, queue tree does not work well, with mangle.
I have some mangle rules in forward chain and queue tree with PCQ.
Some queues process packets slower than others, the buffer has more packets. If I change priority and give better priority to the problematic queue it works.
The problem is with the queue which has more traffic than others.
The router processes about 400Mbit of traffic and processor is 12%.
It is not a bandwidth problem, i have not put anything Limit-Max or Limit-At.

Maybe something is wrong with the priorities in queue tree.

atu · Wed Jun 26, 2013 1:52 am

If I change priority and give better priority to the problematic queue it works.

this is what i mean "can not work at same time",in my case, only one bewteen(Down1~down8) have packets if u changed their priority or Limit at or something.

Just experienced a crash on 6.1 x86 while disabling/re-enabling queue trees. When I re-enabled the queue tree, the router stopped forwarding traffic and ended up rebooting itself. It came back after about 5 minutes with no user intervention. This is on a MaxxWave MW-RM1300-i7 router.

I see a lot of forums posts about bugs in the queue trees in 6.1....what's the latest on this?

atu · Mon Jul 22, 2013 2:07 am

any suggestion or help???

kyob · Fri Aug 02, 2013 10:20 am

I have the same problem.

My queue just stop receiving data from mangle and for example yesterday works fine but today all queues show 0 "zero".

Log does not report any error.

When I edit something in options in queue tree for specific mangle then it's start to work.

Would it be fixed in 6.2?

Puffer · Fri Aug 09, 2013 8:30 am

Any feedback on this ?

I upgraded my RB450G to 6.2 yesterday and the 46 queue trees are not visible in Winbox.
If I go to new terminal console they are all there and working.
Nothing shows in the queue tree window in Winbox, even if I add a new queue tree in V6.2.

Have tried disabling them all and re-enabling them in console and rebooted several times, no luck.

still bugged in version 6.4 !

Bi11 · Sat Oct 12, 2013 6:20 pm

Ditto happened to me.
After I upgraded routeros to 6.4 from 5.2, the queue tree shows all zeros and is not working at all.

I guess the bug is happened when calculating the max-limit for each queue.

parent max-limit=5m
+- child max-limit not set

is not working. may be it was treated the max-limit to 0.

So I set the max-limit

parent max-limit=5m
+- child max-limit=10m

It works, so I added another

parent max-limit=5m
+- child max-limit=10m priority=4
+- child max-limit=10m priority=3

It still works, but when I added one more

parent max-limit=5m
+- child max-limit=10m priority=4
+- child max-limit=10m priority=3
+- child max-limit=10m priority=2

It falls to zeros, was not working any more.

So I disabled the last one that I've added

parent max-limit=5m
+- child max-limit=10m priority=4
+- child max-limit=10m priority=3
X +- child max-limit=10m priority=2

The tree still not working.

So I disabled all children, and re-enable the first one

It works.

It seem that something wrong while calculating the max-limit for each queue.
If an error occurred, the whole tree dies.

After I tried many times to reset configuration, add queue one by one, disable and enable the queue tree, the RouterOS hangs.
The router was no response. Maybe a kernel failure?

So I downgrade to 5.2 immediately, it is not stable for 6.4 .

But I really need the new Queue model in v6. In v6 we can mark in input chain and have no worries on queuing a packet twice.

Hope it will be fixed soon.

Bi11 · Mon Oct 14, 2013 6:10 pm

I can't upgrade the main gateway again for the screen shot.
So I installed a x86 version and the bug can be easily reproduced.

/queue tree
add max-limit=5M name=queue1 packet-mark=A,B parent=global queue=default
add name=queue2 packet-mark=A parent=queue1 queue=default
add name=queue3 packet-mark=B parent=queue1 queue=default
/ip firewall mangle
add action=mark-packet chain=prerouting new-packet-mark=A

I connect the router with ip winbox, so you can see the packet in the mangle rule are increasing time by time.

ros6_queue_s1.png

s1. It works fine with one child queue.

ros6_queue_s2.png

s2. The queue counter stopped when I enabled the second child queue

ros6_queue_s3.png

s3. It is not working even when I disabled the second child.

Bi11 · Mon Oct 14, 2013 6:23 pm

ros6_queue_s4.png

s4, It back to normal when I disabled all the children

ros6_queue_s5.png

s5, Enable one child is OK

ros6_queue_s6.png

s6, Again, the counter stopped when I enabled the second

Bi11 · Mon Oct 14, 2013 6:29 pm

ros6_queue_s7.png

s7, Really, the packet in mangle increased but the queue counter were froze.

This a temporary test router so here is the supout.

Bi11, please write to support@mikrotik.com (at least with a link to your posts)

Bi11 · Tue Oct 15, 2013 7:26 pm

I've already sent the email when I finished detailed post here.
The support says

Thanks, problem repeated, we are working on a fix.
Should be included in release of v6.5

Thanks.

still bugged in version 6.5

You are doing something wrong. Bug reported by Bi11 is fixed long time ago.
my queue tree is working fine and i can't see anyone else complaining lately, so jump to conclusions yourself

bmeiojas · Fri Nov 01, 2013 7:58 pm

Ok, If ATU do something wrong, I do it the same wrong because i have the same problem and can't find a solution.

Simply... simple queue does not work

engineertote · Fri Nov 01, 2013 10:45 pm

atu , you can go for simple queue with V6 .

My queue tree is working too since ROS 6.5

You can add/enable queue tree rules one by one, and watch the counters.
Once the counters frozen, the rule just added has the most suspicious to cause it.

Clean/disable all queues and try again, and try to find the minimal rules that can reproduce the issue.

Print the rules here and MK team can fix it very efficiently once they can reproduce it too.

I'm a software engineer so I'm sure this is a efficient way to fix a uncommon bug.

djdrastic · Wed Nov 06, 2013 9:13 am

While we've had a multitude of issues with 6 , qtree's luckily haven't been one of them . Most of our 5.xx rules with a little bit of tweaking (no global in , global out) import and run successfully.
