Syntax file for EditPlus still would be greatly appreciated

taduikis

Hi folks, I have a question for those who have tried or somehow know it - does GPEN11 pass traffic when it's not powered by local DC power port? I need exactly such device as GPEN11 but I need it to not pass traffic between IN and OUT ethernet ports when there's no power applied via local DC IN sock...

taduikis

Too bad they wasted front space and switch chips for 12 RJ45 ports. If I needed RJ45, I'd put RJ45-SFP modules in.

taduikis

Yeah, thanks. I’ve figured that out already.

taduikis

Bug is still present, even in 2.9 version. Mikrotik, can you please fix it? It's boring every time to reset / restore switch just to upgrade! It’s probably in 2.11 too. That iframe in manual upgrade section now shows chrome’s “aw, snap” icon after upgrade and switch got bricked for good. Have to cl...

taduikis

Thanks for correcting me. But my question stands as before: did packet buffers increase?

taduikis

Sorry for resurecting old topic, but my new one would go with similar name.

What is known regarding this new sw chip (STM32F107xxx) in CSS106? I'm particularly interested in packet buffer size. Is it larger even by few kilobytes compared to old RB260GS(P)?

taduikis

I’m also on that version. Indeed no reconnects every half a minute, everything else works fine too. I have currently set label refresh time to 0:08, and that graph successfuly displays everything up to 5Gbps. Didn’t try custom probes yet. I’ve heard there are success stories with 64bit counters.

taduikis

Yes, I already did that.. All the graphs are with saw-like spikes :) Completely useless... This is graph for 100M link:

Clipboard02.png

I don't feel anything in 6.47.x. I thought it will solve this issue:

Clipboard01.png

But it didn't.. Everything >3Gbps in Dude graphs looks like this :)

taduikis

Our logs are also insanelly flooded after upgrade to 6.47.. You can't really find anything historical and useful there anymore.. only thousand or so login/logout entries.
I'm surprised how MikroTik has this ability tu ruin things for yeeeeears now :)

taduikis

Why do you want to do that?

taduikis

If I upgrade The Dude server to 6.46.4, will it connect to <6.46.4 devices to collect data?

By your warning I understood that everything 6.46.4 will only talk to 6.46.4+..

only the Dude server has to be upgraded

taduikis

About Dude "std" error: To get RouterOS data from the devices, Dude now requires RouterOS to be 6.46.4 or newer. The other stats and of course Ping will still work. This is due to security measures being strengthened. Are you joking here? This way you force everyone to upgrade EVERY devic...

taduikis

Hi,

can anyone share some data on how mass quarantine affects your network traffic? Perhaps we have someone operating in northern Italy for example?

I’m afraid the demand of video streaming service from people isolated at homes will put quite a burden on our infrastructures..

taduikis

What improvement will the new NetMetal ac² provide in comparison with former NetMetal ac (wave1)? Besides 160MHz channels and MU-MIMO, which are basically interesting only for some small indoor/closed deployments for mass end-user access, but have little use for WISP PtP or PtMP.. Unless MT plans to...

taduikis

I repeat once again: - backward compatibility for legacy devices - asymmetric manual downlink/uplink rate selection - automatic closed-loop tx-power control - adjacent channel filtering (like airprism or hypure) - gps sync for channel reuse This was the recipe (in given order) for MT to save their w...

taduikis

I'd like to address your comment in step-by-step: - yes, you're right, the RouterOS is increadible OS with it's instruments, management, capabilities, etc. - NV2 from ~6.42 has been updated and poor signal/quality clients no longer drag down the AP performance that much, also higher number of client...

taduikis

Guys, calm down. Chill a little. Forget MT Wireless. It’ll be like a breakup with a girl: hard, painful, expensive at first, much work, but you’ll get over it. I did. I miss RouterOS superior management and features, since I hate web GUIs and limited console configuration options, I sweared much, mi...

taduikis

We had approx a hundred such setups with 2-18 clients per building. It works quite well and is easy to deploy on roofs. But they’re indeed subject to lightning. We had plenty with fried ports and whole switches together with client routers. Long open cable runs either vertical or horizontal on build...

taduikis

Well, these all new PowerLine devices are ok, but what about MT outdoor wireless? Has MT mentioned any plans to introduce some new AP? Or we're stuck with good ol' RB912/92x?

taduikis

This GPEN thing has been born and dead already, so MT is at least few years late. We’ve been making such stuff out of MT switches since 2010 but now all devices are collected and clients converted to GPON access. It’s way cheaper, more reliable and faster. So you should probably have focused more to...

taduikis

I believe it can be RMAed, but you most probably have to return the whole unit to them. I’ve bought a bunch of replacement 3rd party supplies and just replace them when they fail..

taduikis

I can also confirm this issue. No matter what package is installed on device (wireless, wireless-rep, wireless-cm2), all devices with wireless package fails to upgrade with error message "some packages unavailable". If you try to do Force Upgrade - device reboots with no WLAN interface and...

taduikis

Lets bring this topic back since it’s still relevant 3 years later, because both devices are available on market and nothing new has been released for APs in those last 3 years. This time of course there’s no question whether to buy 912 or not, but more a question of upgrading to 922 for networks th...

taduikis

When testing P2MP networks for best throughput and latency you need to run a test from several CPE's (in a 'all MT' network) and then switch between the different protocols and setting to see what gives best result. Each time though the connection with AP is lost due a config change, the CPE needs ...

taduikis

Well, almost all MT boards suitable for APs have USB port. And ROS have GPS package as I remember. Does this mean it's possible to take advantage of that? MT: Update NV2 to support GPS sync and sell USB GPS modules. Additional profit. You mean clients of Sector A should not see clients of Sector B? ...

taduikis

You mean clients of Sector A should not see clients of Sector B? If so, that's fair enough. And it's achievable with quality antennas with good F/B ratios. But sync is advantageous only on ABAB or ABCD setups. I wonder how MT sync implementation compares with GPS based syncing.. What with NV2 sync ?...

taduikis

Sure, 802.11ac is better than 11n. It must be. But other manufacturers (we all know which ones) still use some implementation of TDMA instead of saving the costs and using industry developed mainstream protocol. Even some LTE networks use TDD based TDMA. So one way or another it seems TDMA is the wa...

taduikis

Well this discussion about scan-list here got a little off-topic and shouldn't steer away our discussion from the main topic which is about Nv2 improvements and performance. To be clear one last time: scan-list is only in effect on CPEs or AP while in scan mode. It's just that - a list of frequencie...

taduikis

I was just about to say that I understand MikroTik's frustration: one user claims performance has improved, other tells horror stories, etc.. And you can't really know if it's because of noob incompetence or because of some valid natural reasons like RF environment or some special equipment combinat...

taduikis

I can’t deny nor confirm that RouterBOOT is ‘drivers’. The FWF files were ~40KB in size and had chipset name in filename. Don’t really have an opinion if 40KB is too much for bootcode only. Maybe some experts would shed some more light on this. I’d really like to know, because recently I saved the h...

taduikis

Firmware: As for firmware upgrades, I haven’t noticed any difference in wireless performance. What you call firmware here, to my understanding is a RouterBOOT bootloader, which has nothing to do with device performance after it boots to OS. But MT staff could verify if it has any effect or not. Old...

taduikis

Well, I cannot guarantee that it’ll do a lot, but at least short GI gives additional capacity by reaching higher datarates on 20MHz. I’ve witnessed performance and user experience/happyness increase numerous times after replacing these 5HnD’s to Lite5, etc. I don’t know how it’s related, but even CC...

taduikis

Is that SEXTANT of older generation by chance? I mean 5nD or something.. I've noticed that older gen chipsets perform poorly and also drag down whole AP a little. Also older chipsets don't support Short GI on 20MHz channels. I rotate and replace old 5nD and 5HPnD devices and upgrade to newer ones wh...

taduikis

I have plenty of them running in open air for a few years and they’re ok. You just got bad luck.

taduikis

I agree. mANT's are terrible in noisy RF.

taduikis

No wonder everyone is complaining and whining about poor WiFi performance.. signals of -20 dBm.. sweet jesus.. help me live through this madness..

taduikis

And by the way, the introduction of TDD ratio setting, was the last major improvement we've witnessed recently. Dynamic 80/20 increased wireless DL traffic up to 20%. That's great, considering that it only took software update and some tweaking. Initial tests of NV2 improvements with high number of ...

taduikis

Yeah, but one of these "other vendors" show us perfectly that the most important part here is AP side. They reuse existing old SXTs or NS5's and make users happy for a time being with speeds up to 30-50M per client and with sectors toping at 120-150M without visiting their households. They...

taduikis

Today I replaced one SXTsq 5ac to good old SXT Lite5 ac. I can say that this new SXTsq is total crap. It crashed number of times with 6.41.2 and I couldn't upgrade it to 6.42.3. And 16M flash is a total pain..

taduikis

@Polky We also wanted to switch to Cambium Elevate, but luckily we do not have to do that anymore!!! :-) Well, these are not really even comparable yet. Elevate is expensive and only supports Lite5, but performance is way better due to huge advantages of AP side: neighboring channel rejection, bett...

taduikis

I also didn't notice any significant increase or improvement. The performance even dropped a little. I'd like to know some more info of exactly what this NV2 improvement do and what problems under what circumstances it should solve.

taduikis

I understand that, same here. I tested on AP with 29 clients, 20MHz, NV2, tdma period auto, N only. Signals and CCQ were great. While doing simultaneous bandwidth-tests on ~10 clients, total throughput with rc46 was 10% lower than with previous relases. The single client performance wasn't really an...

taduikis

Can you post more details about your setup? I’ve tried similar setup and had lower total aggregate throughput per sector than with previous ROS releases. Total throughput per single client wasn’t bad before. We tested the new release, and it works great. n/ac, 20MHz, dynamic dl. ratio, auto TDMA per...

taduikis

I've accidentally found it on my own, but anyway thanks Chupaka. You're as always helpful

taduikis

Sorry for bringing up this topic, but I’m currently trying to do the same: set in-interface to none for many dstnat rules via console. set X in-interface=“” doesn’t work. Is there still no way unsetting it without using api style workarounds?

taduikis

What about precipitation effect on this link? Will rain, fog, heavy snow have serious impact?

When should we expect to buy them?

taduikis

Hi, I've been investigating this issue earlier and I'm actually back on this topic once again since I now need 10G upgrade to my original setup . I tried to set it up on CRS226 and I'm not sure if CRS can even be configured that way: having mixed VLANs - single and double tagged (stacked). I can get...

taduikis

normis, switch to manufacturer driver when scanning spectrum, and then switch back Well, it's not something not seen in other manufacturers implementations. For example Cambium: you have to reboot the device to switch to Spectral Scan mode. This probably suggest they switch the driver just for that...

taduikis

Well, with recent competition from mobile operators, for those, who are based on MT-only networks, sad days are comming.. Clients are demanding higher throughput, simply because content dictates the need for it. I've been exploring countless of options of what to do to survive, and currently I came ...

taduikis

Hi,

nop, I've ditched the CRS and used D-Link instead. Had no time for that kind of puzzle.

taduikis

Yeah, I'm also interested about 100M (155M) SFP support in CRS106-1C-5S.

taduikis

Great news regarding CRS317. Two power supplies is a must for such device. Any chance it will have dual-rate ports so we could pop 1G modules whenever needed?

taduikis

I was going to write that. You can in fact set the tx-power, no problem. But ability to see tx-power value table as before would be nice.

taduikis

Yeah, it's a bit annoying. We've upgraded lots of APs to NetMetal5 for AC, so lost ability to do spectral scans. For installations in some busy places I keep buying good old RB912s just for that feature.. :/

taduikis

It does support non-MT modules. Unfortunately it only supports 1.25G modules.

Can anyone please tell me the FTC11 support 155M non Mikrotik SFP or not?

taduikis

Thanks!

taduikis

Am I blind, or there's no info in datasheets what type of SC connector MikroTik GPON SFP ONU module uses? I mean are they APC (green) or UPC/PC (blue) ?

taduikis

I doubt you're going to find answer to such question here.. Have you tried your PON profile on other non-Dasan ONUs? Everything I tried so far, worked fine with Dasan OLTs. No multicast though. I think it's evil and try to stay away from it.

taduikis

I'd take Netmetal+Airmax sector combo over mANT anytime. Airmax are quite good antennas, especially when paired with some shielding. Price, of course is not a question here, almost for Airmax sector's price alone you can have whole functioning mANT AP. For distant and interference-free environments ...

taduikis

Greetings, I'm getting to the point where certain 1G circuits are soon not going to be enough, so basically I'd need an upgrade. But CCR1036-12-4S is still quite a powerful machine and is perfectly capable, so I'm at this decision here whether to upgrade the equipment to 10G or use link aggregation ...

taduikis

You could have said that in the begining

I've spent an hour or so and thought I was doing something wrong. I haven't got a single AP running in plain 802.11, only in SOHO routers.. So no new function for me

anyway nice to see something being done.

taduikis

Sure it can't. As I mentioned above, I had a problem where 6.35rc1 AP with -rep package in NV2 didn't work.

wireless-rep means repeater, yes. it also has a new wireless driver and many other new features, so It can't be placed as default yet.

taduikis

Well, I think that "wireless.npk" package should somehow be "default" package that is the latest stable. That way you don't really have to know the sequence and keep tracking what is what. Of course there's issues with compatibility, but you can always have any other package if y...

taduikis

-fp doesn't mean Fast Path, if I remember correctly, it's more like Feature pack? BTW, this wireless-rep package doesn't seem to work in nv2 mode (AP - 912UAG ROS v6.35rc1, CPEs - SXT Lite5/5HPnD v6.19-6.28,6.35rc1). Changing to nstreme - clients reconnect ok, changing to -cm2 - clients reconnect ok...

taduikis

I'm in fact a little disappointed with those new SXT Lite5 AC. Mikrotik is obviously cutting corners with them. It's NAND flash is noticeably slower - unit bootup, netinstall and file operations take forever now, no beeper is VERY bad move, also I have plenty of them dead already. If they die, they ...

taduikis

ok, mikrotik thinks it will rise sales on consumer market, so that is it. I know what would not as much rise but prevent from falling: improvement of current and future WiFi software or hardware. It becomes uncompetitive with todays user demand and trends :( and there's already a list of inventions...

taduikis

I included a few and handed to our distributor to deliver them to RMA. We still have not received any such defective adapters to our RMA. It would help a lot, if you sent them to MikroTik RMA instread of discarding them. I tried to contact people in this thread, so far, no luck. Please return the br...

taduikis

Do you plan to merge all those new changes into ordinary wirelessXX.npk (without -cm2, -fp, -rep) package sometime in the future? It's kinda difficult to do a mass upgrade when package name changes every year or so..

taduikis

Spectrum analyzer is a must for a wireless device!

That's the reason I'm not upgrading to NetMetal5 or RB922 yet. I'd do that instantly if they had spectral history feature..

taduikis

Did you know that in RouterOS v6.15 nv2 latency has been improved dramatically. Read more here: http://download2.mikrotik.com/news/mikrotik-news-59-JUN2014.pdf So please upgrade and enable Wireless-FP package to see the difference cm2 also has some improvements for newer 802.11ac and other improvem...

taduikis

It is currently not as good as Dude v4beta3. Some functionality missing, some broken. It was posted above, there is a list of know issues. Yeah, I'm also in no hurry to upgrade everything to new Dude. I've learned to live with the old one :) I shall watch it mature for a while and decide when I'd l...

taduikis

Hi, what's your opinion on this comparison - RB912UAG-5HPnD vs RB922UAGS-5HPacD - while buying gear for new AP tower deployments? While RB922 is obviously a newer product, better CPU, more RAM, supports AC with backward compatibility for N, has a SFP port (which is great for high towers), has a 1dB ...

taduikis

If it strengthens our competitors (that use LTE) it's not that great news at all

taduikis

Some examples please from recent build. DEV seems to remember such problem only from older v3 dude. Regarding RB260, it has really week processor so it struggles with the dude probes. The device it self should be monitored with increased probe intervals. Links with SWoS devices should however be mo...

taduikis

First of all, congratulations, MikroTik! I was waiting for this day for quite some time now. And let me tell you why.. You have routers, switches, cpe's, ap's - basically almost everything small to medium size WISP needs. And The Dude is like a glue for all this MikroTik ecosystem. You can quickly a...

taduikis

We could do that, but they almost all are opened and with DC cables cut

taduikis

I can confirm this. We recently have an adapter or two failed every single day! All of them have the chip inside overheated - the PCB around it is dark brown. Before they fail, they heat up quite a lot.. And yeah, this is from batches shipped in past 1-2 years or so.

taduikis

I was very excited when I saw a second wlan interface at 2G, but my excitement went away immediately when I tried to setup the Virtual AP on it and got notification that L3 doesn't support that feature.. The original intention of mine was to setup a few dummy APs with different SSIDs to make an impr...

taduikis

I think you can. But it will only work in 1000M mode. I've noticed that FTC works in similar fashion as RB260. It doesn't take anything less than 1G. I've tried a few non-MT 1.25G SFP modules, they work ok in FTC. MikroTik, please make some more robust fiber fixation. These devices will be super coo...

taduikis

I expect it to work with FTC11 converter. No ROS v6.33 there. This has to be standalone SFP module.

taduikis

Jeez, this news letter is god-sent.. GPON module is sooo awesome! I hope it'll have some reasonable price though.

taduikis

Well, unfortunately this is how L2 switching works and not much can be done about that, IMHO. And it's where network engineering starts to become more difficult. You should consider reworking your network topology to be more routed than bridged if possible.

taduikis

This is happening on CCR1036. I've experienced this in v6.27 and then upgraded to v6.32.1. I'm not sure, but I think I've seen an entry saying something about "fixed bridge port leak" in some recent ROS changelog. But I cannot find it anymore. Still, it didn't fix my problem. Currently I'm...

taduikis

Thanks, dada! Seems like this is the issue indeed. I've checked the hosts toward which traffic is sent and they are indeed the ones that recently gone offline - ARP entry still exists in the router, but no such MAC address in bridge hosts table. And this doesn't only apply to offline hosts, I witnes...

taduikis

Hi folks, I seek for some advice and thoughts. Recently I'm having this problem with this bridge setup: multiple VLAN's on a couple interfaces + 1 plain ethernet interface are bridged to one single bridge. Those VLAN's then terminate at Access Points and are bridged there to wlan interfaces. Bridge ...

taduikis

I agree. MT is extremely reliable and convenient. Especially with all it's integration possibilities. But spectral-history is very needed tool to plan and deploy your network..

taduikis

How about these Finisar G(E)PON SFPs? Anyone tried them in FTC11?

taduikis

Sorry guys, I'm currently out of office so don't have access to the switch, and cannot try to test anything. But, you can strip the outer .1q tag and let just the inner tag leave the port. using egress-vlan-translation Well, this is exactly what I need. To strip the outer .1q tag (vlan-id=1003) exit...

taduikis

Yeah. Documentation would be awesome, but simple answer if CRS can handle stacked VLAN's as I described above would be a great start for me. Currently I'm not sure if it's possible even and is it worth bothering at all.

taduikis

It should pass tagged frames untouched if 'VLAN mode' is set to 'optional'. You could configure forwarding according to your needs and let the RB work in sort of VLAN trunk mode providing minimal isolation..

taduikis

In fact, any info on simple q-in-q double tagging with CRS would be appreciated.. And if it's even possible. I do have some D-Link L3 managed switches, that are documented quite well and are working ok in similar setups. I could use them instead, but I already have CRS125 with dual PSU in place and ...

taduikis

Greetings folks, I was wondering if anyone had success with simple QinQ setups using CRS switches? When I say simple, I do not mean 802.1ad Q-in-Q implementation using Service and Customer tags, but simply double 802.1q tagging (two TPID=0x8100 headers). So the example demonstrated in MT wiki doesn'...

taduikis

Well, I can add that for me, at least, MT products are far superior than UBNT. Mostly in terms of flexibility, power of RouterOS, price and to be honest - design. UBNT have their edge on proprietary technologies, in-house built chips, huge teams of programmers quickly eliminating bugs, going for >5G...

taduikis

I'm not fully familiar with GPON networks, but as I understand it uses one shared medium per OLT port. It means that downstream traffic from OLT is received by all ONUs, and, at some extent, is upstream. This means you need precise timing for upstream traffic (like TDMA slots), so therefore you need...

taduikis

With the introduction of FTC11 I returned my attention to fiber. It surely has quite bright future and it's congratulated that MT acknowledges that. I definitely believe MT will come up with some sort of GPON solution in RouterOS and a related product-line. Our network is almost 100% based on MT, I ...

taduikis

The product itself is great. Everything that you need for FTTH deployment. As normis said, it has to be simple, to keep the price low. We have lots of places where this will deploy outside customers premises and bolt on directly to existing Ethernet installations. The design is great and it happened...

taduikis

I suspected so. Because to my knowledge, if something is wrong with my configurations (they are very simple), this would apply to all traffic, not only for particular routes. And you are right, the outbound traffic does go through the correct interface (from my point of view), which has that route. ...

taduikis

Hi folks, I have BGP router that's connected to a single upstream provider using separate VLAN circuits for international and domestic traffic. So there are 2 BGP peers established: one providing domestic routes only and other a default route for the rest of Internet. Normally domestic traffic here ...

taduikis

I can confirm that 9 times out of 10 - Port2 is the crashing port, but it happens on other ports also (the crashes are not very often, but on many switches it does add quite a number). Recalibrating PoE (with v1.14) did help, it doesn't crash as often as before, but it still happens (again, on large...

taduikis

I wouldn't say I'm nervous. I'm just curious why no one else is talking about it. That made me think maybe this issue affects only me and I'm doing something wrong. The very idea of this forum is to introduce a problem and try to achieve collective solution, out of which all would benefit.

taduikis

Am I the only one having issues here? Why it's so silent on this topic? Today I had another unpleasant crash which caused me to physically get to the site to do local power-cycle (I haven't done that for ages).. I think it's about time to start burying MT warranties and physically solder bypasses on...

taduikis

Dude, nstreme is becoming more and more obsolete. We have ~90% of our network running on NV2 now and don't miss nstreme anymore..

taduikis

Yeah, this was news for me two. Tx-power control and review is worthless for now. Have postponed the upgrade of P2P links to AC using NetMetals. They need a little bit more time obviously.

taduikis

Yeah, and current monitoring circuit is completely out of range mostly. If it's measured value is used to cause power-cut decisions, no wonder all these things happen. For example in my sshot you can see that RB912UAG is drawing more than 500mA which is just impossible for that plain board. RB260GSP...

taduikis

Btw, capacitor helps. It's not necessary to check "Long PoE cable on Port1" in my described setup when capacitor is connected just before RB260GSP. Razaali1, I'm not sure what you're trying to refer here, but jumper idea is quite good to bypass short-circuit or overload protection. Honestl...

taduikis

Crashed again. This time 'PoE status' somehow got 'disabled'.. Setting 'PoE out' to "on" made the unit energized

Clipboard01693.png

taduikis

Can anyone post their experience with these power issues? Do ports have to be recalibrated once again if power loss is happening on them? v1.14 helped a lot, I only have one to two crashes per week on about 12 switches, but it's still annoying. Crashing port seems to be random now, not only Port2. A...

taduikis

I never had problems on ports other than Port2. With v1.14 even port2 seems to be stable for over a week now..

taduikis

Add some planned upgrade feature, that gets done upon next RouterOS start, no matter if shutdown/reboot was graceful or not. This of course should be voluntarily and separately triggered with required packages being uploaded in advance. It does add some risks of course, but I bet some people would/m...

taduikis

I had this same issue today. RB260GSP (FW v1.14) was powered over ~20 meters of 1 sq.mm wire via DC plug with 27.6V/2.4A PSU and threw "Short circuit" in PoE status no matter what settings were applied or what device connected. LEDs on RB I was trying to power-up kept blinking shortly with...

taduikis

Glad to see that effort is being put on solving this issue. What I can tell, playing with PoE priority and Power-Out (forced on, auto) settings doesn't change anything, Port 2 keeps randomly crashing and in order to get AP accessible via ethernet again, you have to do a power-cycle through RB260GSP ...

taduikis

Well, that's the problem, I suppose. I receive "ceased: connection refused" notification from remote peer after trying to reconnect. Seems like it's caused by my ISP's policy. I've managed to shorten the time by creating a OnMaster script that disables the peers and reenables them after 2....

taduikis

Yeah, everything works fine. But I'd like to have some faster reconnection to BGP peers when router switches to master. According to the log, TCP connection to the remote BGP peer is established almost immediately but BGP peer state remains 'idle' for up to 10 seconds. I guess there's nothing much I...

taduikis

I can confirm this problem. I had few unexpected hangs and somehow they're always happening on port2 (on 3 different switches). Remote power-cycling via web makes it working again. I seriously doubt that it's related to power shortage, because I run power from 27V 6A PSU, using thick wires and I had...

taduikis

Well, seems like I found acceptable solution already. At first look, Proxy-ARP seems to be a solution, but it doesn't work on the same/single interface. So you need what cisco calls - Local Proxy-ARP. MikroTik doesn't really have it by default, but this guy here ingeniously thought how to make one. ...

taduikis

Hi, I'm currently struggling at the setup that for easier understanding I provided example picture below. Let's say there's an AP with forwarding between wireless clients disabled. While disabling forwarding is a good thing for security this also means any communication between wireless clients that...

taduikis

Dang.. Seems my knowledge was little dated. There were times you couldn't do VRRP on VLANs

Ok, I'll give a try.

Thanks!

taduikis

Well, you're missing the key point, that you have to use "Force upgrade" there. You can have whatever packages you want in your Dude, it will not upgrade throwing an error "some packages missing". What you described is a basic and fundamental thing that applies to upgrading ROS w...

taduikis

The reason is you didn't provide a working solution for the problem this topic adressed.

And your definition of old is strange at best..

taduikis

By saying physical, I mean physical router or connection failure (if router fails, crashes or let's say rats eat the WAN cable out), not physical router replacement. VRRP would seem a valid solution, but I have a couple of VLANs on a single interface to peer with the ISP and without some scripting I...

taduikis

ckgth, have all the required packages in your Dude and do a force upgrade. It works. The only annoying thing to me is that after upgrade I have to manually login and disable the neighbor discovery for wlan1 (I originally keep it disabled), because of syntax difference between v5 and v6 in /ip neighb...

taduikis

Hi,

does anyone know any good setup for a simple physical (in case of power loss, failure, crash) BGP router redundancy without having separate BGP sessions to upstream provider? A little downtime is accepted, but options with as little as possible are prefered

taduikis

Does anyone have a syntax highlighting file (.stx) for EditPlus? These guys seem to have it: http://bbs.routerclub.com/thread-70366-1-1.html But their forum is closed for public registration and it's not possible to download attachments.. :( The highlight scheme is not perfect, but it'd be okay.. ht...

taduikis

RouterOS is okay. But the other welcome features on CRS would be: per-port configuration and monitoring, DHCP Option 82, DHCP snooping prevention, VLAN support, forwarding between ports control, ACL, loopback detection, multicast filtering, etc.. In general - all the stuff that's required & impo...

taduikis

Honzam, This is a hardware limitation. You must use "All rates fixed"

So this means that this is not going to change with newer versions of ROS or SXT hardware? Aren't there any issues when using all-rates-fixed?

taduikis

They are directional, but simply don't have properties of really good antenna. Overall, they are the best we can get now for CPE. It'd be good to see them improve more over time.

taduikis

That is why we gather in this forum!

Wonderful idea, I'll try it out as soon as possible.

To debug these links i use a groove pluged directly to the antenna.

taduikis

Distance is 2 to 5km. No obstacles in the way, Fresnel zone is clear enough. I also see that Rx of Chain0 is very inconsistent and peaks to -80 on AP side. That is not the normal behavior me think.. :( I shall try to replace pigtails with shorter ones made of LMR400 cable.. If that won't help, RB's ...

taduikis

I keep hearing from various sources that these Jirous antennas are indeed very good, and they sure seem to be. But we have few links with JRC-24 DuplEX and RB711GA-5HnD's and unfortunately I cannot brag with good results. Both ends of the link are identical, radios are in separate aluminium enclosur...

taduikis

This was explained somewhere in this forum. It's how is and you cannot do anything about it.

taduikis

Experienced the same thing today. Honestly, the Dude and MikroTik production is a really good stuff to my opinion.. But we're considering slow transition to Ubiquiti, because the difference isn't really worth the hell we're sometimes going through. Been at our colleagues in different region recently...

taduikis

Shields? Can you give more info?
Any info when 5.21 is expected?

taduikis

normis said that mikrotik has fixed this problem in new batches. there was even a photo posted with 711 having a metal connectors. Personally I haven't seen them yet, so..

taduikis

True. Ubnt works out-of-the-box, mikrotik needs fine-tunning, which can sometimes be quite painful. But it's mostly very rewarding after. We operate 100% mikrotik network in an extremely rf polluted environment and mostly only intentional changes or power disruption resets the uptime of sometimes hu...

taduikis

I wonder if it would be possible with serial port and some ROS scripting?

taduikis

Sextants are basically rb711-5hnd routerboards hooked up to 18dbi dualpol antennas. In fact you can take rb out and use it as you want.Like all mikrotik rb's they work as they are supposed to.

I still think there should be a bigger gap in antenna gain between sxt and sextant..

taduikis

Ok, I found an ugly way to get multiple wan ip's with 751G out of single WAN wire. I now have two different public ip's on ether3 and ether4 and would like to NAT them thru different wireless SSID's. But it seems it's not going to be possible because they're on the same subnet and share the same gat...

taduikis

You should do nat at customer cpe. That way you'll have complete isolation from whatever is happening behind your customer's eq. Most of them don't even care about it and for those who want to have their own wan router, you can setup a transparent bridge on cpe. You can use APs/Routers in bridge mod...

taduikis

The most common cause for this is the quality of connectors and their crimping. Replace connectors with new ones and give a try. If you are sure they are fine and it is still happening, you probably have a faulty device connected to the other side of mikrotik. It has happened many times for me and i...

taduikis

I can in part agree with Lakis. I've also experienced few times that enabling nv2 on AP effectively kills that channel for neighbor AP's. And I don't think it's interference, because everything was and is operating perfectly with nstreme.. Some time ago I read some post or article explaining why cou...

taduikis

I believe you need some queuing setup that gives voip priority over other user traffic. VoIP does not need much traffic, but latency is critical. I would also like to hear some opinions about how to implement any means to shape traffic at client side and at AP's in p2mp scenarios aswell.

taduikis

Greetings.

I wonder if it's possible to somehow get more than one dhcp lease thru a single interface? I'm aware that I need to have different mac addrs, but is there a way of doing it with ROS?

This is needed to do NAT to separate public IPs for two different customers.

taduikis

Sorry, but that sxt sector made me laugh and mourn at the same time :/

taduikis

I too think you should try achieving your goal with nstreme. After many days spent trying to get nv2 working, I gave up and found nstreme superior in everything..

taduikis

Tapatalk only

taduikis

As far as I can tell it didn't loose dhcp, but the problem with dns address redistribution which was fixed in 5.15 reintroduced.. Very annoying

taduikis

I will. Can't imagine life without The Dude anymore. Mikrotik, please don't abandon it.

taduikis

I have done that. Works perfectly

It's cheaper to buy a RB that already has L4 license, unless you have somehow earned some spare licenses.

taduikis

There are many antennas mounted close to the sxt. But none of them are pointing to this direction, maybe except a 90deg MARS sector. Either way it's not healthy behavior for sxt, in my opinion. Soon I'm going to replace it with high quality panel antenna, and shall see how it all changes. As for cle...

taduikis

Yeah, thats right. It's completely 180deg -71 from ~1km. From ~630m I saw ~-65 to the same SXT also from behind. I've taken some screenshots to show my colegue in case he doesn't believe me.. :) Mostly sxt's operate in station/st bridge mode, so they don't show up in scans and no one notices this fl...

Yesterday I was one click away from upgrading one of our UPA's when I saw some client traffic moving and postponed upgrade

Now it kinda scares me to do it

taduikis

Sure you can operate them on the same pole. But you have to use quite big frequency gap to avoid interference. Mount them as far apart as possible also. At least 30-40cm between. SXT is a CPE, not intended for corporate use on masts with many antennas. As much as I'd like to use them for near p2p li...

taduikis

Now that's funny. NV2 nothing. Migrate to the Airmax UBNT. Clients will not wait

Could anyone please remind me what we're specifically talking about?

taduikis

I believe not much. You only reduce channel polution in unused pol. if it matters to you.

taduikis

You can uncheck chain0 tx if you use it on v-pol only

taduikis

Yeah. And that is sad. It seems that they need so little to make their already great product just perfect..

taduikis

Nv2 ping times are higher, try using nstreme instead. But yeah, it's sad ubnt outperforms MT with TDMA

taduikis

pppoe is for client authorization. I have other means of managing them. I'm wondering more about isp side..

taduikis

This reminded me of yet another feature worth mentioning. I'd like to have an ability to export scan results to a file (from winbox mostly). I'm collecting site surveys during client installs recently. This sometimes gives useful information about channel usage in that area. Screenshooting is very i...

taduikis

NV2 is TDMA based protocol that uses the channel more aggressively. It means that in most cases you effectively rule over the channel you are using, pushing out other interferers. Give it a try anyway. I have fixed that kind of problem such way..

taduikis

So no insights?

taduikis

Most likely interference. Judging by 'poll timeouts', you use nstreme? If correct, try NV2. Otherwise you might need to try changing freq.

taduikis

You can scan for about 5-6seconds via terminal. Or you can use a script to scan for as long as you want and put the results into a text file.

As for notepad, count me in too.

taduikis

How you secure your router is entirely up to you. Mikrotik only provides means for doing that and they are more than enough. Wiki is quite clear and definitely not outdated. Firewalling is basic networking and not very MT related

taduikis

Winbox mac-level stuff like neighbor discovery and mac-login works only in Layer2 network. Routing is Layer3, so there is absolutely no way you can discover mikrotik devices located in mentioned subnet..

taduikis

That's quite normal if 60-70 is single stream tcp traffic. Do you use nstreme or nv2?

taduikis

Well, normis recently gave out that they are working on a new winbox, so I assume they are making non-plugin based program which I hope will have quite alot of improvements and it's a perfect opportunity to listen to community suggestions and feature requests, me think. And honestly, I have used web...

taduikis

Greetings folks, this is more like a general networking question than mikrotik related, but I thought some of you might provide some suggestions out of personal experience. Next month I'm obtaining a public IP block (PA) from RIPE which will be statically routed to us by our upstream provider. I int...

taduikis

Signal strength should be enough for >25mb anyway. Try to change channel, switch nv2 to nstreme. Under load ccq should be 90-100% bothways.

40mhz 11n with nstreme/nv2 on such hardware would do 150mbps tcp no problem. Udp should show around 220. I assume you have good LoS with clear fresnel zone?

taduikis

Having a per device notepad would be awesome. I have alot of devices configured in a manner that would be difficult to understand without separate explanation. The general device notebook would help alot. It would also be helpful to write down initial signal strenghts to cpe's, etc.. BTW, I've heard...

taduikis

Absolutely not at all.

taduikis

It seems that transmitter in this unit has blown off. This behavior is pretty often seen on r52hn cards. I have RMA'ed few of them previously.. I have a different problem though with SXTs: the signal strength are worse in chain0 rx and chain1 tx. It looks like this in registration list: Tx/Rx Signal...

taduikis

It's not necessary to sell different products that only have difference in software. Mikrotik should simply offer discounts for license upgrades.. I would have upgraded few L3's in past, but since L4 license costs as much as whole unit, it doesn't make sense to overpay for it

taduikis

Yeah, dB's are logarithmic units. Convert them to mW to actually compare in linear scale if you like..

taduikis

Check '/export compact' feature. It only exports the settings that differ from default ones and ignores mac addrs

taduikis

I'm kinda new to this stuff myself, but I think IPs are handled by different organizations in US and Europe. IANA and RIPE respectively. It doesn't really matter by who the subnet was issued for your matter. But for any low level ip handling they are the ones you have to deal with. You should someho...

taduikis

I have similar situation. I'd like to try downgrading to 4.17 to see how it affects the link, but I'm not sure if I won't loose conectivity to remote site? I do have to reach other end physicaly, don't I?

taduikis

That horn antenna looks quite interesting. Not many manufacturers make them I believe and it makes me wonder why. They are considerably small in size, relatively high gain, can be dualpol. Are there some kind of limitations related to this design that it's not popular or what?

taduikis

For 5 mile link you don't need very powerful equipment. Of course it depends on other factors also, like LoS, but if it's all clear you should probably be enough with a couple of RB711GA's, some high gain directional MIMO antennas and adequate aluminium enclosures.. Not long ago i've established a 3...

You might also want to check this thread: http://forum.mikrotik.com/viewtopic.php ... 8&p=318195

taduikis

Check your cabling. You are most certainly having some physical networking problems. Recrimp connectors, with more care this time. I've seen 10mbps on some poor cables. Replacing them took care of the problem.. Give it a try at least

taduikis

It's a router, not server. But if you do need it badly, metarouter is your only chance of running sql server on RB hardware.

taduikis

I haven't yet exceeded the limits of 711ga since I only use it in 100mbps bridged mode, but could you please provide some figures in what scenarios and at what throughput it starts to choke? RB800 is sure nice thing, but it seems a bit overkill for a p2p link..

taduikis

Two batteries with 100Ah connected in parallel (you said 12v) makes a total capacity of 200Ah. That is a lot and needs quite serious charging solution. By the rule of 1/10, it'd be like 20A at least. I suggest to go for higher voltage setups. What you need 12v for anyway?

taduikis

Somehow it only reports the distance in 802.11 or nv2 mode and not in nstreme. Keep that in mind.

taduikis

We use a lot of them and they all operate at default txpwr. Can't say these cards are very good, but they are ok. Recently we had few factory defective ones with low tx. All were from the same party.

taduikis

Accessing usb from metarouter guest would open lots of possibilities. But I think this ain't done easily..

taduikis

Clipboard01.gif

Yeah, smart people use IrfanView

Sorry for offtopic, I couldn't resist not to comment on that

taduikis

That what happens when you use <incorrect> hardware

In mikrotik its pretty straightforward - use station-bridge and you're ok. For ubiquiti, you will probably have to use some sort of wds mode to get transparent bridging. Check their wiki or forum.

taduikis

But it might send the message to that troublemaker

give a try

) it'd be fun atleast.

taduikis

Try uploading separate packages that you require from .zip file and then /system reboot. This way it should definitely work. If not, netinstalling might be necessary. The bootloader upgrade is not critical but highly recommended. You can check it's changelog to see what is different between versions...

taduikis

Point is: is it possible to standarize frame contents or frame encryption between different hardware? Of course it is possible, but it will not happen. Don't even think about it, it's a dead end. Sure. MTik needs to push their own products in any way they can. If they start making their equipment h...

taduikis

Solving the problem "mechanically", as wirelesswaves suggested, is not quite legal also, but most effective

taduikis

I have similar situation with 711GA. It seems that the router doesn't boot up - there are no startup beeps indicating that. However netinstall works. It finds the device, partitions and reinstalls it, but after reboot nothing more happens. Should I return it to RMA?

taduikis

Why do you want wds at all? Use 'station bridge' instead. It's so much better that way. And it works perfectly with nstreme!
WDS only makes sense if you need transparent bridging between non-mikrotik devices..

taduikis

Hmm. I do see settings for Rx and Tx in interface config dialog and you can set any limit you want in kilobits (k) or megabits (M). I haven't tried this setting though, so can't tell more.. You can only limit the download speed by the interface...and it is their defined speeds as well... you can not...
