What do you mean here? Static Rule for all, or automaticly Rules per PPPoE-Login?whe mangle the tcp mss
Hi,
first off all make shure that you don't use the automatic change MSS feature. You can use 2 static rules for all instead of 2 dynamic rules per PPPoE-User for that feature. Save 1.198 rules by 600 connected PPPoE-User.
Second, don't use the rate limit per PPPoE-User or Profile, this also generate 2 simple queues per loged in PPPoE-User. Use PCQ-Queues instead against adress-lists or IP-Pools. This also save hundreds of simple-queues.
You maybe also use a little bit higher queue sizes (default = 10 if I remember correctly) try 100 here.
If you done this all, you should be able to run some more PPPoE-Clients without having that problem. But still remember also that the PPP-Stack in linux is not optimal for use as access concentrator. We have a system which is able to terminate > 50.000 concurrent sessions, but this is not linux based.

I think the problem is not related with PPPoE code, but with dynamic queue and PPPoE interface. It happens with much less than 500 online users (500 users is the max I have per MK router).Hi,
I don't belive that is really a bug. Linux is not suitable for terminating hundreds of PPP-Users. Regardless if it's L2TP or PPPoE. Maybe they have some small problems, so you run a little bit earlier in that problem. But over all, if you need to terminate 500+ Users, I prefer non Linux based solutions. As I figured out, we have a system which terminate 50.000+ PPP-Sessions without any trouble. No it's not CISCO or Juniper and their is no Linux PPP-Stack used.

I am here too.
I started to experience this issue something later then 2.9.3x.
The early 3.x seems not affected but now the problem is there too.
Support wrote me to pass to new feature present on 3.10 to use pcq.........
Strange that all the major MT issues were about queue.
I think they should improve the area of the code.

Ros
Can you share this script?I have the same problem. I see the queue simple without counting upload or download. If this happend i do an script to disable and enable this queue, after that the queue work fine.
use dynamic Address-Lists, not static IP rangesDo not want to have to change a users IP range when they change rate plans.
I heard on part-15 list that a number of users with a large number of PPPoE sessions jump to Imagestream as a PPPoE server. They state after that everything works fine. Imagestream is also based on linux AFAIK.I don't belive that is really a bug. Linux is not suitable for terminating hundreds of PPP-Users. Regardless if it's L2TP or PPPoE.

I have this problem even with much less than 500 online users.Hello,
I think MT is a serious solution, but sometimes restricted to the Linux. If you need more in some special situations, e. g. a PPPoE-Server for more than roundabout 500 concurrent user, you may take a specialized solution for this topic, and not a full featured RouterOS System.

If Mikrotik could simply integrate a house keeping script that would detect PPPoE sessions with the queue problem and bump them off line or something that would be great. I just had a 'user' thats paying for a cheap 256k account run 5m all last night and max out a backhaul. Most likely everyone else feed by that backhaul had slow laggy service all night due to this. Come on Mikrotik we need a fix!I have this problem even with much less than 500 online users.
Hi Matt, it´s really annoying, whe have the same problem here. It already happened to us with just 40 connected users (nobody can say it´s due too much users online or too much traffic). It´s a huge bug that will make us abandon MK.If Mikrotik could simply integrate a house keeping script that would detect PPPoE sessions with the queue problem and bump them off line or something that would be great.

This case we have to read:Hi,
we are supporting roundabout 250 WISPs in Europe using our concept with one central PPPoE-Server. Nobody have this problems with less than ~ 350 concurrent users.
WISPs with more than ~ 300 concurrent users are migrating away from the automaticly generated queues, they use adress-list or IP-Pools and PCQ.
WISPs with more than ~ 500 concurrent users we use our own special device for terminating tunnels with carrier class quality.
Maybe you have some other problems?

I have 650 pppoe client on average, 900 on the heavy hour without problem.

Well, now you know and I´m not the only one. PCQ is not an option for me. I have some bandwidth fixed plans but I have a lot of users with dynamic bandwidth plans. Can I collect usage statistics of each PCQ queue by user via SNMP to generate reports? I don´t think so. There are a lot of services we have today that cannot be done with PCQ.Hi,

all I can say that we never see this problems with a RouterOS 3.x PPPoE-Server and less than 300 to 350 concurrend users, and we have access to lot of such systems. This is why I suggest that you maybe have any other problems.It already happened to us with just 40 connected users
I swapped my two pppoe server from simple queue to pcq, following the indication of this presentation http://mum.mikrotik.com/presentations/US08/janism.pdf
i have very wired results.
Some of my clients are really limited to the max limit of pcq, and some others to a quoter of that.
If i disable the queue into the wueue tree the clients that are overlimited started to fly..............
I checked evertyhny...mangle trying different mangling strategies, but anytime there are clients over limited.
I am going back to dynamic simple queue.....
Very frustrating-
Ok, don't take this as Tik bashing... We still use it exclusively for core routing and firewalling, and are very happy with it.
But.... We've been using an ImageStream linux router for PPPoE termination for several months now, following a fiasco with Mikrotik. The hardware is a 2.0GHz Celeron, with 1GB RAM. There are currently over 1800 simultaneous sessions with queues. Load average is 0.60, and everyone is getting their speeds consistently. Management UI sucks, and leaves much, much more to be desired, but performance is smooth... I'd take a happy customer over a shiny GUI any day.
Anyhow, it IS possible to terminate lots of PPPoE sessions with queuing on minimal hardware. It's all in the implementation. I hope Tik gets these issues fixed soon because I miss the user interface
I agree with you. But as everybody is saying it´s because Linux kernel problems it´s better to hire Linus.I would like to say that MT rules, but its pppoe server sux. So far I couldnt make at least one device (no matter what) running ros 3.x smoothly with pppoe server. The same setup but running DHCP and PCQ works perfectly on 3.11. Our pppoe servers was running a maximum of 50 simultaneous til ros 3.5 and above. Now we are forced to stuck upgrades in 3.4 for pppoe server and deal with other bugs that are already fixed on 3.11 (rip, ospf, etc). We have already a pppoe server MT running 2.9.45 smoothly since about a year, but you cant even dare to think in upgrade it. I think it is not really a bug on MT pppoe server, but I assure you the system get very unstable when using it on ros 3.11 and seems that its instability is increaseing on every ros version after 3.0rc. Supouts sent and they see nothing about freezing. Even the best hardware ive seen (rb433) from MT this issue happen but very often compared to a RB532 f.e. Ive lost my sleep for about a month to downgrade devices running pppoe server back to 3.4 and now the nightmare is back due to RIP/OSPF stuff bugged. Resuming, my issues with MT are only one: its pppoe server.
Do I need to hire normis to solve this?
If so how did Imagestream get around the linux kernel problems? I really doubt its a kernel issue.I agree with you. But as everybody is saying it´s because Linux kernel problems it´s better to hire Linus.
I have never heard Mikrotik say that. Only place I heard that was in this thread and it did not come from Mikrotik. Perhaps they told someone that somewhere else?3. MT says it is a kernel issue
after months of posting..............
If they said that I am happy. Did you get that in an email? As long as its fixed soon, within month or two?4. MT says we will fix it.
I have completely different experience:i was referring to a generic way they approc an issue.

1) report the issue in details
2) Mikrotik - unable to repeat
3) me - here you go full access to my router
4) Mikrotik - yes, we see the issue, can we reboot, put debug etc...
5) me - yes
6) Mikrotik - ok, it looks like we have done it, could you test our bugfix we applied it on your router.
the most problematic part is 1) - you really need to put research into it, what kkind of traffic, what kind of situation etc. - If you just yell that "I have a problem, fix it." then ofcourse you will get something like that.
BTW: there are actual problem with Linux Kernel - i major cases related to Intel products (those guys always make something differently)
is it a joke?didn't "next release" fix the issue?
No, I'm serious. If support promised that bug is fixed in next release - Did you try the fixed release?
How do you expect MikroTik to fix bugs, magically apply fixes to your system without upgrade???
Where?*) fixed bug - in some cases web proxy https with parent-proxy did not work;
*) added default-route-distance setting for DHCP client;
*) mesh protocol
*) multicast
*) user manager
*) added ability to dst. nat only address or port, not both at the same time;
*) ospf
*) ipsec
*) port remote-access
*) ethernet half duplex modes on rb400 series work now;

I also have noticed this problem.. All my PPPoE concentrators are running 2.9.46. I've been holding off on upgrading them until this particular problem has been addressed.
Basically what happens is a user connects, but for some reason the simple queue does not get created for their interface, thus giving them an unlimited connection. I've had users getting 10+mbps because of this. I usually catch it, and the fix is to remove their PPPoE session and it will then reconnect and recreate the queue properly. It happens inconsistently but I'd say I see it happen a few times a week.
I have 3 PPPoE concentrators with 300+ users on each of them, and it happens on all of them. I have a whole Customer Information System (CIS) that is designed around RADIUS, Mikrotik, and PPPoE.. So changing to PCQ wouldn't be my ideal solution. I do have the ability to specify an IP address pool through my CIS but that would require going through the 1000+ accounts and changing each one to match their specific connection speed. Using a dynamic address list may be possible, but can you add an account to an address list through RADIUS? If not whats the point? I'm looking to reduce administrative overhead as much as possible.
In that case. Is it possible to write a script that at 3am or so evry night it disables then reenables all the queues on the box? Might be a temp fix?In my case the queue is created but the traffic doesn´t flow thru it. I now a person who have this same problem that told me if you disable que queue and re-enable it the traffic starts to flow thru it.
Someone else in this thread stated they switched to PCQ like that and still had the same issues.Dynamic PPP Address list looks like it might be a viable solution... at least for me.. I can change the attribute in my management system so instead of passing mikrotik-rate-limit for the rate plans i can create dynamic address lists based on the same value and just change the RADIUS attribute.
Then create the PCQ's and get rid of all the simple queues.
This might be a solution... at least for my setup.
But at 3am just a few users are connected and this is a random problem. If the user connect in the middle of the day? Most of my users connect, use Internet and then disconnect.In that case.

In my experience this affects more users that stay connected 24/7 then those that disconnect and reconnect. Problem is on a user connected 24/7 that is a bandwidth hog they will be online with no rate-limit for weeks. Reseting the queues every 24 hours insures they will only get away with it 24 hours at most.But at 3am just a few users are connected and this is a random problem. If the user connect in the middle of the day? Most of my users connect, use Internet and then disconnect.
This is a important information. I will pay attention for how long time the user was online when this happen. But how do you disable and enable a dynamic queue? This option is not available at WinBox for this kind of queue. This can be done via script?In my experience this affects more users that stay connected 24/7 then those that disconnect and reconnect.

It can be done on terminal. Not sure if disabling and enabling the queue actually causes the PPPoE user to be ratelimited again. Someone else in this thread heard it did.But how do you disable and enable a dynamic queue? This option is not available at WinBox for this kind of queue. This can be done via script?
Our experience is like this one:i think the discovery path is the following:
1. MT says: there isn't any problem;
2. MT says: we tested your configuration and didn't find anything;
after dozen mails and supout....
3. MT says it is a kernel issue
after months of posting..............
4. MT says we will fix it.
I hope MT will fix it ASAP.
Thanks Normis.. this is what everybody here wants.. MK team trying to solve the problem.we have done some fixes and improvements in simple queues and pcq, and made a special "test" package. if anyone is interested to test this package, and help mikrotik solve this problem, write to support
This is exactly the same problem whe have. We will test this beta version that Normis is talking about to see what happens.The TX on ETH0 is the upload as ETH0 is the public interface.
I am just monitoring ETH0 in Dude for RX and TX as it shows me what the overall site is doing. It helps me spot inconsistancies in the sites bandwidth usage (thats all)
I do not have any IP address on ETH1 as I am using pppoe only on the local side.
The point is that pppoe user account apt79 in the screenshots is getting 9.5Mb Download as per the pppoe account dynamic interface, eventhough apt79 has a dynamic queue limitation of 256k Download/128k Upload as per the profile for his pppoe account. The queue limit appears correct eventhough the dynamic pppoe interface is not being controlled.
I used torch to check the amount of bandwidth that this user was getting by the public IP address that he is using (this is blanked out in the pictures above for privacy issues)
If I log apt79 out of the system "manually" when he reconnects he seems to be limited correctly again.
This happens with other users too randomly.
Bad news. I had some hope with this beta version.It happened again last night. I have been running ROS 3.12 (Beta) that Mikrotik gave me to test and this is the first time that I have seen it all week. It usually happened at weekends in the past. Most users are at home then in this apartment block.
See DUDE graph. The upload speed of >12.5Mb is impossible with the customer base in the building.
Does anyone have a script that I could use to detect the excess usage and disconnect the pppoe account until this issue is solved ?
I hope this fix is not the same as 3.12 beta because as told above the problem was not fixed with this beta version.ROS 3.12 is now released; change log tells that problem was fixed. Any one tested this version yet??
We have been running 3.12 for over 2 days now but it typically takes at least a week to act up so am not sure yet. So far so good though. Will likely update to 3.13 here shortly though.Does release 3.12 solve the dynamic queue issue in the field?
For us is pretty difficult to upgrade a pppoe server because we use some voip pppoe client that some time lockup when the pppoe server reboots.Anyone? I had a user getting 10+mbps for a week.. Wasn't really effecting overall performance for the network but annoys me that this user was getting something for nothing !
Was running 3.12 shortly after it came out. Now running 3.13. Have not seen the issue YET. Its too soon to be sure though. Why not try it?
Matt
We updated some MK routers (x86) to 3.13 where we have more problems with this bug. But we have to wait some days to see.any update from who is testing 3.13?
then please report also the platform, RB or x86.
Regards
Ros
Yes,Can anyone confirm this?
very disappointed!!!!Yes,Can anyone confirm this?
RouterOS 3.13v + x86 not solved , the problem still lives .... unfortunately
This is not what is happening to us. The traffic we saw on PPPoE interface was the real one in use (we could see it at radio interface used for MK backhaul). When it was displaying 4Mbits on interface he was really using it (but this traffic was not displayed in queue).Hi all, just to add - 3.13 also x86 (WRAP) does seem to still have the queue issue, We are seeing something strange, Winbox will report some PPPoE clients moving 20Mbit/s, but that sort of speed is impossible at some of our towers, as some are only fed 5Mbit.
We are rolling back to an earlier version
No, they are really using it. We can see the over traffic at all equipments (switchs, routers, radios, etc).Ops, maybe we are being misled to believe the clients are using the extra bandwidth without actually using it?

This will cycle all PPPoE clients on n interface. When they reconnect a new queue is created that works for a whileCode: Select all/interface pppoe-server server print
MT CPE will usually reconnect seamlessly meaning an outage of around 12 seconds
Please, if someone could do this it would be of great help!anyone who can give full remote access to your router (with missing queue problem - where queue is shown, but not working for the specific customer), please contact support and we will look !

Can you please contact MikroTik support team and grant them access to your router so they can investigate what is going on? They prompted to help but we need someone with the problem.Were are seeing the issue on 3.13 yet as well. What makes it a real pain is a user gets like several meg upload for a few days but then later after connection goes up and down they are locked back at 512k upload. Then they call complaining the connection is not working right. Argh. Hopefully Mikrotik gets this fixed soon.

I have not gotten a response from Mikrotik on the ticket I opened with them on this last week. Hopefully they got everything figured and 3.14 will solve this even so.Or could HCI so kind to contact MT to give them access to the router?
It will be great if they can give you MSN address, it will be easier.Hi Normis,
please may you check the HCI ticket?!?!!?!??!?!?!
it is strange asking support ro access a router with the issue and then not reply to such ticket!
Regards

I don´t know about HCI but we are trying everything here to allow MK team to access our machine. We are even planning to change our MK to valid IP address just to allow it.Sorry to hear that, seems that people are more into complaining than into helping...
Good news Normis..we got access to hci router too now
We have our PPPoE users split between two geographically seperate PPPoE access servers and neither at this time sees over 650 active connections at a given moment. Many users have single PC and/or connect on demand. I have not noticed any packet loss issues but thats not saying there are none. Perhaps you should have given Mikrotik access to your router?did you see some packet loss (on the others) during an addition of a pppoe client interface apart of the missing queue? It is araisng when i have more then 900 pppoe clients with some of them are missing the queue.
latest unreleased build I thinkis it a test package about 3.13 or based on 3.14 rc1?
regards
Ros
we are still testing if the fix worksHi Normis,
may you confirm that the fix is into the final 3.14?
In fact into the change log I don't see anything about pppoe.
regards
Ros
Well - another bug found, thanks to HCI.
We were pretty lucky actually by finding and fixing this bug:
every 32768th simple queue or 65536th queue tree have no effective limitations.
In HCI's situation it took ~2days until 32768th queue was created, but if clients don't use traffic it is impossible to capture. But luckuly we managed it.
I found a way to work around this problem without restarting the machine. If you have a static simple/tree like p2p control only you need is disable and enable this queues and the pppoe queues will work good.
Friends, try this and post if it works!
What about 2.9.52 ?it will be included into 3.15
I dont think there will be any backports to 2.x series anymore because the versions are too different.What about 2.9.52 ?
But, bug is the same.I dont think there will be any backports to 2.x series anymore because the versions are too different.
But it will be fixed in later version, in 3.15 =)But, bug is the same.
The problem is that, fixing bugs in two releases, duplicates the work and defeats the purpose of releasing a new version. It's true that the release system of MikroTik could be a little more sophisticated and I think they should estabilish official end of life dates to each release overlapping with new major releases and be clear about what fixes would be supported and for how long but, for now, that's the way it is...But, bug is the same.I dont think there will be any backports to 2.x series anymore because the versions are too different.
You do not have enough traffic to reach 32768th simple queue.I am using 2.9.50, in 2.9.50 i didnt see that problem at all.
may be i didnt see
Email Mikrotik and offer them access to your router to do this.I'd love to test on ours.. I have 3 PPPoE servers with 300+ users on each all with reliable power..
