Full/Half duplex on Omnitik routers
by Paul Julian 18 Mar '15

18 Mar '15

Hi guys, I have posted before to this email list about an issue we have at customer site where direct Ethernet connections between wireless routers (1 x CPE and 1 x AP back to back) all of a sudden drop from full duplex to half duplex mode, even though they are hard set to 100M full. Previously I have considered POE injectors, cables, etc, but I have just had it happen on the weekend and again this morning at a different site. The common components between these sites are the Gigibit POE injector which comes with the Omnitik radios and the Omnitik radios themselves, at one site I have RB411's plugging into the back of the Omnitik and at the newer site I have SXT's plugging into the back of the Omnitik. So I have tried replacing POE injectors, cables, and also tried leaving the interfaces as auto-negotiate and hard setting them to 100M Full, but the original site still fails from time to time, the link goes to half duplex then at some random time after that just goes back to full duplex by itself. I can play around with the interfaces and get it back up and running normally but clearly I don't want to do that and aren't just able to jump onto the radio and do it at any time. Has anybody else experienced this problem with Omnitiks and if so is there a solution ? I am running ROS 6.19 on the latest problem unit and firmware 3.17. Any suggestions would be appreciated. Thanks Paul

LTE/4G USB Modem
by Alen Orsolic 10 Mar '15

10 Mar '15

Hi All, Due to a number of recent enquiries I am seeking feedback as to known working 4G USB modems, in particular Telstra network supported devices. As we don't stock or use any ourselves any comments and or suggestions would be greatly appreciated. I have canvassed the MikroTik hardware support Wiki, but would appreciate any positive working and in production solution. A number of customers are looking at implementing a failover based product but, current 4G USB modems purchased from Telstra have yielded unsatisfactory results. Regards, Alen

MikroTik LNS config
by Nick Pratley 09 Mar '15

09 Mar '15

Hey all, Having a few issues getting an LNS session working! Any one got this working with a Cisco LAC? Provider removed the tunnel password from when I was running a Cisco as the LNS - but for the life of me I can not get it to authenticate the sessions. Torching the interface, I can see from the providers LAC the l2tp requests coming in to me when I start the session. I've read all forum posts on the 7 pages that a Google search returns - but everyone has confirmed they are able to complete the task without posting any configs. So far, I have L2TP Server Binding PPP Secret with user(a)domain.com and password L2TP profile with local & remote address >From what I have read - that's all that is needed - but it's not working. Unfortunately there is nothing in the logs either. Hoping someone who has set this up can spare 10 minutes and give me a hand :-) Cheers Nick

Apologies for the delayed emails - sending from my tablet PC had source email address with ".au" on the end, but address registered to the list has just ".com" version :-} Figured that some comment were still relevant to the topic - sorry for being apparently silent in the meantime! ;) Cheers, Mike.

CCR1009 crashing - how to debug?
by Damien Gardner Jnr 05 Mar '15

05 Mar '15

Hey All, My CCR1009 rebooted 6 times overnight. I thought maybe it was a problem with 6.25, so upgraded to 6.27. That was a bad idea, as it took a remote hands power cycle to get back into it. I then did a downgrade (which took it all the way back to 6.21.1) Seemed ok, till I tried to scp the 6.25 files up to it. As soon as I went to view flash, it rebooted again. Interestingly it hasn't upgraded to 6.25, though i don't dare try to view the files on flash to see if they actually copied.. After much swearing and praying, it seems to be stable - so long as I do not try to use winbox. Seemed like as soon as i used winbox (or the http variant), the router would reboot. However now I can't even use winbox. Seems to be stable if I don't try to login to it at all, so I think I'll leave it sit there for the day, and head to sydney tonight. What can I do to try and work out WHY it's rebooting? All my logs say are: system,error,critical System rebooted because of kernel failure system,error,critical router was rebooted without proper shutdown, probably kernel failure There's nothing else about the reboot at all. Is there any more debugging I can turn up for it? If all else fails, I can shove my old little DL360G3 back in, and fire up quagga, but if there's a way to debug and fix it without heading to Sydney, that'd be nice ;) Thanks, Damien -- Damien Gardner Jnr VK2TDG.

Telstra EA/MEF Link information for queues
by Paul Julian 04 Mar '15

04 Mar '15

Hi guys, I have finally had the time to redo this. I hope it helps somebody, it's not gospel but should be close Basically it gives you the queue settings for Telstra Ethernet Access or MEF standard links when running on a Mikrotik and is required to ensure a link is not choked by backoff problems, the slower the link the worse they are..... I hope this comes through better this time, I tried to work out the formatting a bit but I'm sure you can work out which column is which L2 and L3 speed are Mbit/s, Limit-at, Max-Llimit and Burst are all Kbit/s L2 Speed L3 speed Limit-at Max-limit Burst Queue Type Queue Size Packets MTU Size 6 5.88 5880 5976 96 pfifo 8 1596 8 7.84 7840 7960 120 pfifo 9 1596 10 9.8 9800 9960 160 pfifo 13 1596 20 19.6 19600 19920 320 pfifo 25 1596 30 29.4 29400 29840 440 pfifo 34 1596 40 39.2 39200 39696 496 pfifo 39 1596 50 49 49000 49640 640 pfifo 50 1596 60 58.8 58800 59520 720 pfifo 56 1596 70 68.6 68600 69400 800 pfifo 63 1596 80 78.4 78400 79360 960 pfifo 75 1596 90 88.2 88200 89240 1040 pfifo 81 1596 100 98 98000 99400 1400 pfifo 110 1596 150 147 147000 148760 1760 pfifo 138 1596 200 196 196000 198080 2080 pfifo 163 1596 300 294 294000 298000 4000 pfifo 313 1596 400 392 392000 396800 4800 pfifo 376 1596 500 490 490000 496800 6800 pfifo 533 1596 600 588 588000 595200 7200 pfifo 564 1596 800 784 784000 792000 8000 pfifo 627 1596 1000 980 980000 988240 8240 pfifo 645 1596 Any suggestions, omissions or updates please share, this is just what I have developed over the last 30 or so links we have installed.

ccr1036 Q
by Alex Samad - Yieldbroker 02 Mar '15

02 Mar '15

Hi Fairly simple, but I haven't done this on a CCR yet I want to put 3 eth ports into vlan 201. Does the vlan id realty matter as its only staying on the CCR ? Do I bridge the 3 ports together and then add the bridge to vlan 201. At some point in time in the future I might want to extend 201 further into the my network. Currently I have 2 SFP+ ports bonded and then I have vlans on top of the bond. Alex

Telstra Ethernet Access Shaping Guide
by Paul Julian 27 Feb '15

27 Feb '15

Hi Guys, I thought it might be worthwhile to put some information together for Telstra Ethernet Access services based on the MEF standard. This is a loose guide based on the Telstra TSIS documentation which isn't helpful for Mikrotik so I have attempted to convert the Cisco parameters to Mikrotik based on the information in the TSIS guide and also from personal experience. Please provide feedback if you think these figures work or don't work, I'm happy to update them as we keep rolling out links and any suggestions would be welcome and be shared on this list as they can be a challenge to get right and the slower links really suffer from Telstra dropping packets if they aren't configured right.

problems posting?
by Mike Everest 27 Feb '15

27 Feb '15

Hi all! I dicovered this afternoon that this list was set for maximum message size of just 40k - any email larger than 40 was being uietly discarded :-} So if you were attemtping to post, and wonder why they were not forwarded, it might be related to large content or attachments or large sig etc. I upped it to 2M, so most of it should work now - even so, I suggest that it would be nice to refrain from sending large chunks of content inside posts to the list ;) Comments are welcome! Cheers! Mike.
