RB2011UAS-RM - auto negotiation problem

Fri Feb 22, 2013 9:27 pm

Hi guys,

I have just installed a RB2011UAS-RM for a customer and discovered a problem with the LAN speed negotiation.

I connected LAN port 3 on the RB to a BT FTCC modem (ECI V-2FUb/I Rev.B) and discovered it negotiated at 10 Mbps. First thought was of course bad cable. Having replaced the cable the same problem exists. I started fiddling around with switching the auto negotiation off and full duplex. Forcing 100 or 1000 Mbps causes the link to be lost.

I then moved over to port 6 on the RB - same problem with auto negotiate. I think I may have been able to force 100 Mbps but only half duplex (struggling to remember exactly what I tried).

Next I tested the BT FTTC modem connected to a laptop using the same cable - full 1000 Mbps
Then I connected the RB to the laptop using the same cable - full 1000 Mbps on port 3 and 100 Mbps on port 6.

Is this some kind of bug in the RB hardware or incompatibility between devices?

The BT modem is locked and as such not a single setting can be changed on that device.

I've had to put a standard 10/100 switch between the two devices just to get above 10 Mbps.

Tried ROS 5.24 and v6.0rc11 with no change.

Any suggestions?

Cheers

Henry

Update 24/02/2013: Found another Mikrotik user from the UK with the same problem and similar equipment. The thread is here (with no positive outcome)

Someone with a similar port speed issue here (with no positive outcome)

And another thread with port speed problems here (with no positive outcome)

And finally some mention of it here here

I wouldn't be surprised if Mikrotik have not been able to reproduce the problem reliably. There have been problems of the other OpenReach modem the HG612 having auto-neg problems on some PC ethernet card drivers although I have not seen such comments regarding the ECI V-2FUb/I Rev.B. The other 3 links don't really help a great deal - rather sketchy details.

I had the chance to look at a 2011 which had 4 ATAs attached and two had come up at 10 Mb. I thought maybe that situation would have provided some hard information but in fact it turned out that two of these brand new ATA were set to 10Mb whereas the other two were set to 100Mb and the installer had simply not considered that possibility.

It would be useful to know if an unlocked ECI V-2FUb/I Rev.B reveals any settings which can be adjusted to avoid the problem.

Perhaps I could loan some hardware to Mikrotik so they can investigate further? I'm sure this problem is going to affect everyone in the UK with an FTTC modem.

I had a look at the screenshots of the web interface, there aren't any settings relating to port speed.

I'm going to try a crossover cable today as an extreme long shot.

Also, for others thinking of going down this path, I'm having stability issues with the pppoe connection. Every 24hrs or so the connection will drop and the Mikrotik is unable to re-establish it. From the logs I can see the broadcast packet going out but no response. Restarting the BT modem solves the problem.

It would seem the BT modem and the Mikrotik router just don't get along. Unfortunately this is the solution we have invested in! :shock:

We have worked around this problem with our customers by them using port 10 on the RB2011 set at autonegotiate they get 100 Mbps full duplex to the BT supplied FTTC modems.

We have reported this to MikroTik support, and supplied supouts etc using both common FTTC modems as supplied by BT.

Thanks for the info Nick. We tried port 10 this afternoon and in our case it doesn't help at all.

Currently we have 100 Mbps half duplex with auto neg off on port 6

Re: RB2011UAS-RM - auto negotiation problem

Tue Feb 26, 2013 9:13 pm

I too have problems with the auto-negotiation with the RB2011.

For some reason my ESX server directly connected to it (Intel PRO/1000 PT) often comes up as 100Mbit instead of 1Gbit. What I do is connect using winbox, tick off auto negotiation on that port for 5 seconds and then click it on again, it will immediately take up the right speed of 1Gbit and work. As long as I don't reboot the RB2011, it stays correct.

The same sometimes happens with my UBEE cable modem. It should sync at 1Gbps but sometimes comes up as 100Mbit. The same trick (tick auto neg. off and after 5 seconds on again) fixes the problem till I have to reboot.

I've have this through Version 5.18 up to 6.0rc11 right now. No clue why it happens. Different cables or anything don't help anything. But with the little trick, it's stable and speeds are good. I do really get 1Gbit (117MB/sec using Iperf) so the switch chip is working correctly, it just the sync after booting that doesn't work correctly.

Wed Feb 27, 2013 1:01 pm

Interesting to know it's ECI and Huawei

I'm still running at 100 Mbps half duplex at the moment but even that doesn't seem totally stable. Here's what happened to the FTTC connection last night out of nowhere (having been up since 17:30)

2013.02.27-02:01:41 <172.16.1.252>: route,debug,event debug: Interface change
2013.02.27-02:01:41 <172.16.1.252>: route,debug,event debug: interface=ether6 - WAN2
2013.02.27-02:01:41 <172.16.1.252>: route,debug,event debug: status=UP
2013.02.27-02:01:41 <172.16.1.252>: route,debug,event debug: mtu=1500
2013.02.27-02:01:41 <172.16.1.252>: pppoe,debug pppoe: ether6 - WAN2: terminating sessions: interface state changed

There was nothing in the logs saying the interface went down, which seems odd to me. It went 'up' at 17:30 and then 'up' again at 2:01 with no 'down' in between. :?

Dont know if this is helpful to you but my RB450G is connected to the BT supplied VDSL modem and auto negotiates at 100mb full duplex on port one.

This has worked fine for me from day one and i get my full download/upload bandwidth.

AAAH! I'm having this problem too! I thought it was my equipment!

It depends on what hardware I am connecting to the port. Cheap equipment (Dlink routers, Chinese cameras, etc) all need to be manually set to 10meg half duplex to connect. This also makes a difference depending what port group I use. If I use the 100meg ports, the problem is more common. The gigabit ports do the same problem, but it seems not as often.

I have same type of issue against MT own equipment (http://forum.mikrotik.com/viewtopic.php ... 45#p362645).
Note: According to the Wikipedia sources the autonegotiation is a must for the GBit/s LAN (http://en.wikipedia.org/wiki/Gigabit_et ... 1000BASE-T) and disabling it is illegal.

Hi,

I have a RouterBoard 2011UAS-RM which I am using with an Openreach FTTC modem (HUAWEI Echolife HG612).

I am seeing 100MB Auto Negotiation on Ether 1, the RB is running 3.04 Firmware and RouterOS 5.24.

Have the same problem with RB600, RB411 and also X86 computer with RouterOS. And also many different HW variants on the other end from enterprise cisco switch to few SOHO switches do the same. Even if I turned off autonegotiation at all on both ends of the wire RouterOS was reporting wrong speed on status page after some time and ethernet link had about 80% packet loss. Turning ON and again OFF the autonegotiation solves the problem for unpredictible amount of time. From that i guess it is the SW problem we are now using version 4.10 so I will try to upgrade and let we see. What versions are you experiencing this with?

The thread is about some particular problems which have been reported on the RB2011. The symptoms you mention actually sound quite different. Note that on Cisco ports if it does not auto-negotiate it will speed sense with some potential problem results - e.g. if you force a Mikrotik port to 100 Mb full duplex the Cisco port will speed sense to 100 Mb but adopt half duplex which will kill the throughput on that link.

Hello all,

I am experiencing the same auto-negotiation issue with 951G-2HnD RouterBoards. I am an IT Technician working for a Broadband reseller, and recently we have decided to trial MikroTik products. Today I was configuring a FTTC 80/20 connection for one of our clients who has an ECI Modem (B-FOCus V-2FUb/r Rev B) supplied by BT. The 951G-2HnD is only negotiating to a 10Mbps link with the modem, and with auto-neg. switched off it only works with 10Mbps selected. Nevertheless I had to revert back to the Draytek router we've been using.

We are quite fond of the RouterBoards capabilities and cost effectiveness, so a solution for this issue would be greatly appreciated as we'd like to use them in the future.

Model : 951G-2HnD
Current Firmware: 3.04
Current Version: 5.24

I had the same problem on an RB2011 today. I put a 5 port switch in between, but this isn't ideal for various reasons.

Is there any update on this ticket MT please?

We were using the 2011's pretty exclusively as FTTC terminators and now they are completely out of the window and we have being forced to use a competitors model as this is just silly after founr months. I have a bay full of 2011's that are about to be returned to the distro if not..

It is not a small bug, but a major rewrite is needed. If we would add it to v5, it would make it exactly the same stability as v6

411AH set to auto, while 493G also - connect via 100mbps/Full
if i set 493G to 100fix/full, they won't negotiate.

You need to set both devices to 100/full, because you disable the autonogotiation process when setting the port to 100/full.
ALWAYS configure both sides with the same speed and duplex settings!

It all depends on the "other" device. If you set a Mikrotik port to 100 Mb FD and connect it to Cisco gear the Cisco gear will speed sense the 100 Mb but will select half duplex. The general rule is either use auto-neg or manually set *both* ends.

OK,i've tried 493G vs 411AH
to auto only on 411AH side and 100FDX on 493G side - no success
i've also tested 100FDX fixed on both side, no success.
what is even stranger: 411AH shows link, while, 493G not shows link.

Some devices (cisco, but probably more) also disable auto-mdi when disabling autonegotiation. So you probably need to use a cross-cable.
Please use only autonegotiation. If that doesn't work your cable might be bad.

Just upgraded to v6.0 and the issue is not fixed.

We're getting by using forced 100MB half duplex :?

Still looking forward to a fix :)

Re: RB2011UAS-RM - auto negotiation problem

Wed Jun 05, 2013 9:18 pm

I'm also experiencing issues I believe are associated with the auto-negotiation problem. When I connect the sfp on the RB2011 to an spf port on a Netgear GSM7312 switch it will not bring up a link. Every other switch I have in the office with an SFP port will work just fine, even the layer 2 version GSM7212.

I've tried setting both sides to 1000/full but it wont pass traffic, but if I recall you cannot specify a rate and duplex for an SFP. I'm using mikrotik modules and can verify that the configuration works with other switches. I hope this gets resolved soon, I have a several GSM7312's in production and cannot deploy RB2011's until it gets corrected.

Re: RB2011UAS-RM - auto negotiation problem

Thu Jun 06, 2013 5:18 pm

Hi there,

We use MT7 51G for some FTTC connections and are seeing an issue when connecting to BT VDSL modems made by ECI where the interface comes up at 10Mbps Full-Duplex. We see this in both RouterOS 5.2 and 6.0. Anyone else seeing the same issue using the 751G? Any workarounds found (other than placing a switch in between the devices)?”

thank you in advance

Hi again,

I just wanted to make a quick amendment to the above post - the RouterBoard we are actually experiencing the issue is the 951G - not 751G

thanks,

M.

MarekG:

we made some test with the following devices:
433GL, 2011, 600, 493G (we have some more devices what we can test)

if all set to auto - they are syncs.

If any of the devices (or both) set to 1000 fdx, than only 2011 vs 600 links, others are not.

I'm interested if any of you have tested this - and wish to test the above with 750G, SXT with Gig, 450G etc

So 6.1 is out. No sign of a fix.

This is starting to get very frustrating. I'm a first time buyer of Mikrotik and have good things about the products. However I bought this unit back in February and 4 months later I'm still unable to use it. I appreciate that this is a bit more involved than a simple patch but is there any idea when this will be fixed?

I just tried 6.1 on a RB2011UAS-RM and an older RB2011UAS-IN, and still have the same issues. I understand that any new product will have bugs, but this issue should be priority as it makes these devices completely unusable.

We already fixed this issue with auto negotiation on RB2011 with Cisco devices, it is in the Changelog too. Apparently you both have some other brand of devices and the problem is slightly different. We need more info to fix this.

Wow, I'm assuming from this that no one is looking into this issue. Nowhere in this thread does it mention Cisco. It clearly states ECI and Huawei devices. Mikrotik have confirmed that they ordered equipment to do testing with way back in March.
It's worth noting that this also affects the RB951G

Go back to the first page of this topic, it does mention Cisco in several posts by different people.

I stand corrected, some people did say they were having similar issues with cisco devices. However, this thread was started because of issues with the ECI device and later proved to also affect Huawei units. The fact that there has been a fix for Cisco is of little use to us. So I ask again, is this being looked at? When can we expect a fix? Do I give up hope and return the unit?

We still don't have your specific unit available for testing. it is not something that we can easily get. Are you willing to send one to us?

Are you sure both sides are configured for auto-negotiation?

I thought they'd used remote access into your system to test the modem?

Were there no discussions/conclusions at the time??

Remote access was granted but support could not glean any valuable info as it required downing the gateway port which they obviously couldn't do remotely. The best they could do was have me send a support file to them, which I did. That was the last I heard, despite asking for an update since. That was over a month ago. :-x

Just got new revision RB2011UAS-RM. Zyxel ADSL-modem(s) also affected (Model No. ZyXEL P-660RU EE). Huge number of FCS Errors and max. 500kbps RX on that port. Both GE and FE ports affected. Sometimes disabling Auto-Negotiation helps but really rare when works without FCS errors. Several times enable/disable ports required form proper connection. Tried with ROS 6.3, no change.
P.S.: I can send ADSL modem for testing if needed, because it is totally useless with RB2011.

What is the "official" word from Mikrotik on this problem? I don't really need my RB2011UAS to connect at Gigabit speeds but it would be nice if it did!

What happens if it's a hardware issue? Do we all get replacement Routerboards?

As long it is a non-issue for the MT you can not do nothing much. Wait for the warranty to expire and you get nothing even if they accept it as a HW fault.

Same problem with RB951 and VDSL modem/router.
Auto-negotiation for 10Mbit, but connection isn't working anyway.
No difference if set to manual speed/duplex.

Tested with ROS:6.2, 6.4, 6.5, fw: 3.07 - 3.10

Just had FTTC installed here and went from a 15 Meg ADSL2+ connection to a 10 Meg VDSL2 connect because of this issue! Again using an ECI B-Focus V-2FUb/r Rev.b modem and RB951G, running ROS 6.5 with firmware 3.10. Routerboard will only connect at 10 Meg, taking off Auto negotiation does not help as link state is only achieved when set at 10 :-(

VDSL sync rate is 40 Meg

Temporary got round issue by putting a cheap switch in between modem and Routerboard. I have a spare modem and I *could* post it, depending on cost.

Pretty disappointing really as this makes my 40/10 FTTC pointless. If they can't issue a fix soon I'll have to return/sell my Routerboard and further purchases won't be forthcoming.

It is not that simple an answer. It does indicate a hardware issue and not just a software one. What is the fix? We need closer explanation of what is that all about, because there are similar and somewhat related ethernet issues with the MT gear (the ethernet port flapping for instance) and that is not just a mere inconvenience.

Re: RB2011UAS-RM - auto negotiation problem

Fri Nov 08, 2013 1:33 pm

I queried options for return. This is what I got. No news yet for 951G owners but I don't hold out much hope.
Using RB2011 it is still possible to establish 100Mbit link with BT modem by using
ether6-ether10 ports.

This incompatibility is not caused by defect in any way, therefore warranty does
not cover it.
I'm utterly astounded at the lack of support/customer service from Mikrotik. I bought this unit way back in February and it has been gathering dust ever since due to it being completely useless with BT Infinity. I've hung on this long for a fix to be issued, only to be told that not only will there not be a customer installable fix, but that I have no right to ask for a replacement unit which does have the fix. Which ever way you cut it, the device I bought in good faith has been proved to be not fit for purpose and I'll be damned if I'm buying another one.

If the incompatibility is not a defect, then why is it fixed in later hardware revisions (per the message that some of us received above).

It has to be faulty, and if you took them to a small claims court I believe you'd get your money back that way (though IANAL).

I'm about to purchase a few RB2011UAS-RM units. What can I ask my supplier to be sure I'm getting the new generation of RB2011UAS-RM devices that doesn't have this bug? I cannot work with a device with such problem, it would be an expensive paper weight.

Well, two things, I have the RB1100AHX, and it has this auto negotiate issue and FCS errors on ETHER 1, but connected it to EtHER 4 and it doesn't, well I should say so far, as to why I do not know.

Also this would explain why the RB1100AHX's went on sale for about half the price in the recent past. So, don't buy them when they are on sale, you are probably getting a bad one.

MT, this does suck, this should be a warranty issue, and we should all get new boards!

p.s I have two of these paperweights.

If you bought it from us, you can RMA it.

Thanks Nick. As it happens I did buy it from you guys. You'll have to forgive me, but what's RMA?

Done. Thanks. Soooo I guess the next question is...if I return this one, and order another one, how do I know I won't be sent another duff one?

Re: RB2011UAS-RM - auto negotiation problem

Mon Nov 25, 2013 3:06 pm

I've just been testing FTTC modems with 2011s and 951Gs and the new Cloud Router Switch

I have found that the stock we have of 951G-2HnD, RB2011UiAS-RM, and RB2011UAS-2HnD-IN will all connect at 100 Mbps full duplex on their gigabit ports when using the Huwaei.

However they will not work properly with the ECI. They end up with 10Mbps full duplex

The new Cloud Router Switch is happy to negotiate 100 Mpbs full duplex with both Huwaei and ECI FTTC modems.

Edit:
Just tested 951Ui-2HnD and they work fine with ECI and Huwaei

Hope that helps

Nick.

This problem still exists on the RB9xx series equipment.

Ah that's not good. Just my luck to have an ECI modem. So I guess my option is to replace the modem or sack off the RB951 all together.

I've had a bit of a brain wave. I don't want to power 3 devices so I've been looking at PoE capable 100mb switches to kill 2 birds with 1 stone as it were; make the RB connect to the ECI modem at 100mb and power the RB without an additional plug.
That got me thinking, would one of these achieve the same?

Or
http://routerboard.com/RBGPOE

As loathed as I am to buy another Mikrotik product, at a couple of quid it would be much cheaper than a PoE switch.

Just received this from Mikrotik support:
Hello,

Recently, the RB2011 and RB951G Gigabit port connection has been tested with this
particular device and a hardware related incompatibly was found.
This problem is addressed and fixed for all new RB2011 and RB951G, unfortunately,
it is not possible for old ones.
Sorry for inconvenience this have caused.

Regards,
Janis Becs
So I guess that's that.
(Bit of an old thread - but)
Anyone know how to determine the hardware "new versions" of the RB/2011UAS-2HnD-IN ?

I've just fallen into this one - the BT Openreach modem and the Mikrotik bouncing around and negiotiating 10mbit on the gig ports.

So I reconfigured to use ether10 (10/100) without issue.

Bit of a pain when the pppoe wizard doesn't automatically add a "input drop" for the pppoe-out1 device tho - leaves the whole thing open to the internet!

I would also love to know this. I've got a RB2011UiAS-RM that Mikrotik was unwilling to replace which will not autonegotiate with all of my devices, and I've been holding off replacing it because I have no way to tell if a new one will be fixed or not.

Just a quick one.

We had the same issue with Mikrotek routers and BT ICS modems.

Our fix was to set the ICS modem to a fixed bitrate and full duplex.

Now they connect at 100M via eth1 on the router.

I had to move my Samsung SUHD TV from switch 2 to switch 1 to be in the same subnet as my phone without a bridge, and I cannot get it to DHCP even if I disable 1000Mbps on the RB2011 port, like I had to do on switch 2 successfully.

No good, attempting the move to switch1 resulted in total TV networking failure when putting it back in switch2.

I had to factory reset the TV, find out how to pair the smart remote again, and reconfigure the whole TV setup again.

The link appears established and it seems a lease is being offered but not being taken by the TV.

The weird thing is that this problem happens only on switch1, even without master port.

It also does not connect if I use static settings.

Was this ever resolved, or did Mikrotik shove it in the too hard basket?

We have this on 2x RB2011-RM's. Both switch groups flapping.

Actually, read up and see it was a hardware fault. So how do I tell what version of the 2011 it is?

+1
Same Problem here with RB3011 and v6.37.2
Have a VDSL2 50/10 with Draytek Vigor 130 as DSL Modem

- If I use Auto-Neg it says 1G but I only get about ~30Mbit/s or less from WAN
- If I set it to 100M Full I get about 48-50 Mbit/s

I've also a very strange behavior with Netflix because the website itself is working, but the steam does not. Doesn't matter if I use the website or the iPhone app....

Update Netflix:
Seems, that I might have a problem with fragmentation. If I reduce my MTU on my Windows 10 client from 1500 to 1451 it works fine.

Constellation:
((DSL Modem - MTU1500)) -> VDSL VLAN7 -> ((MTU1500 - Mikrotik RB3011 - MTU1500)) -> ((MTU1451 Client))
