For SFP/SFP+ cages, highest rate supported by the module will be chosen. Setting speed to 1Gbps and disabling auto-negotiation is needed when you use SFP modules in SFP+ cages, or if you use SFP+ modules in SFP cages. That being said there are modules that support auto-negotiation, such as S-Rj01 an...

What did you mean by "when 2 ports of the same device are connected (MikroTik and Huawei) through the MikroTik passive cable, the ports are rising." ?

The picture was used just as an example, you can view full context here https://youtu.be/kA9Gu25vt6w?t=1030

Did you mean GPEN? You can get GPEN11 brochure here https://mikrotik.com/product/gpen11#fndtn-downloads

CRS326-24S+2Q+RM is meant to be used primarily as a switch. You can use 1000Base-T transceivers, we have our own as well - S-Rj01 and S+Rj10. And you can also use SFP modules in SFP+ cages, you will just have to disable auto-negotiation on the port and set the speed manually to 1Gbps.

About questions from tangram : The QSFP+ interfaces are as follows: qsfpplus1-1 qsfpplus1-2 qsfpplus1-3 qsfpplus1-4 qsfpplus2-1 qsfpplus2-2 qsfpplus2-3 qsfpplus2-4 The ports can be configured as you wish, for example you could connect Q+BC0003-S+ to 4 different CCR's, and just bridge the 4 interface...

If it's hEX POE, then first solution is not applicable as it doesn't have serial port.
Now you could do as cdiedrich said, and make a script that would log you in and disable Netwatch. Or you can try adding host with that IP. If neither of these is an option, then you have to reset the device.

If the device has serial port, connect via that and after boot up paste this command in "/tool netwatch set [f] disabled=yes". If you know the IP, you could try connecting host with that IP to the device, so ping would be successful, then you can disable rule afterwards. Last option is to reset conf...

Regarding second question, GPeR doesn't add any noticeable delay, for example, at 1500m you have 0ms ping response time and you still can push 1Gbps.

You should use "/interface ethernet monitor", as that is where actual link rate is displayed. Export is not correct tool for checking rate, as it is dynamic value and can change in case of auto-negotiation, or it can be non-existent if link is not up. Since by default auto-negotiation is enabled and...

What tdw wrote is correct. "speed=" is only taken in account when you disable auto-negotiation. If you have auto-negotiation enabled, then "advertise=" values are used instead.

Could you please give us your ticket number?

Hello, this definitively is not normal behavior. Please write us email to support@mikrotik.com

You might want to check these sections:
"/ip arp " or "/ip neighbor"

Here's an alternative for sending traffic between two directly connected devices. DUT IP- x.x.x.x/xx TG IP- x.x.x.y/xx You can create single packet template on TG: /tool traffic-generator packet-template add ip-dst=x.x.x.y ip-gateway=x.x.x.x ip-src=x.x.x.y This will send traffic from TG, through DUT...

CCR1016-12S-1S+ has "sfpplus1" cage, not "sfp-sfpplus1", so it can only work with "SFP+" modules, and not "SFP" modules, that might be related to your problem.

Information if it's MSA compliant, should be noted on product page, when buying SFP modules or twinax cables, majority of modules are compliant. There are no vendor locks in our devices, as such it should work together with TP-Link using, twinax cable. But if you are unsure about TP-Link side, you c...

You should check if it's made according to Multi-Source Agreement (MSA) , it should work if it's compliant.

@sp0tteh
CRS125-24G-1S-IN only has SFP cage, not SFP+, so you cannot get 10Gbps rate with it.

@tojoe
You can distinguish new S+Rj10 revision by “/r2” at the end of the serial number.

There shouldn't be any issues with passing Jumbo frames, if modules are from r2 revision. Please send us email, describing your setup and problem in more detail, at support@mikrotik.com

Have the same problem with UF-SM-10G & CRS317-1G-16S+ with 6.42.12.
Any RoOS version with fix?

Could you please send us email, about your setup and problem, to support@mikrotik.com?

RB3011 only has SFP port, not SFP+, you can use SFP+ modules in it, but they will only work at 1Gbps.

Click on your profile icon on top right, then go to User Control Panel, Overview, Manage drafts.

You need to adjust both L2MTU and MTU values for interface, and if interface is part of a bridge, check MTU values for the bridge and other bridge ports as well.

S+31DLC10D will work in RB3011UiAS-RM, but only at 1Gbps rate, because RB3011 only has SFP cage, that means modules inserted into it, can't work at 10Gbps. If you don't have the modules yet, I would recommend getting regular SFP modules, not SFP+. Modules in table below are tested to work with RB301...

Multi-core support for bandwith test is added in 6.44beta versions, you can try with them. Personally I like using "/tool traffic-generator", works well. Of course for true results you shouldn't generate traffic on the test device itself. Two "1036" are easily able to achieve 1Gbps between one anoth...

Please write to support@mikrotik.com and describe the problem in more detail.

If you are trying to connect to first port your connection might fail due to default-configuration. Try to connect to it using different port. Be sure that, when you try to reset the device, you start pressing the reset button before applying power. https://wiki.mikrotik.com/wiki/Manual:Reset#Button...

Check your auto-negotiation settings, they should match on both sides. Also check your cables. What devices are you connecting together?

Hello. Tell me, please, where in Ukraine can I study and pass the MTCNA exam?

You can find trainers here https://mikrotik.com/training/centers/europe

Yes, you can use "sfp+ interface" to connect to "sfp interface", only caveat is that you might need to adjust some settings on both ends of link as configuration must match. More info can be found in link below. https://wiki.mikrotik.com/wiki/MikroTik_SFP_module_compatibility_table#SFP.2B_interface_...

I'd recommend not using CRS as main router, as it's primary function is of a switch. Check test results of product before making a decision: https://mikrotik.com/product/CRS112-8G-4S-IN#fndtn-testresults As for performance testing iperf is fine, traffic-generator also is fine, or maybe even bandwidt...

How to upgrade factory firmware (RouterBOOT)?

To upgrade factory firmware you need to use special package that can be found here:
https://wiki.mikrotik.com/wiki/Manual:R ... bootloader

We will soon add newer version packages on that page.

Please, add multi-cpu(multi-core) support to Bandwidth Test Tool. this is required for 10G/SFP+ speeds testing between CCR1036/ or between CRS317-1G-16S+RM devices. At the moment Bandwidth Test Tool can generate only 2Gbps and utilize only 1 core on CCR routers. Of note: I have some CHRs running on...

You should not use the Mikrotik tool. It is inefficient and does not use multi cores. Connect a machine either side and do a “real” throughout test. I agree with you, the BTEST can be inefficient, but I also tried whit 3 CCR linked via 10G SPF+... CCR_01<>CCR_02<>CCR_03 same results. Can you sugges...
