Re: Troubeshooting Performance testing

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...

Re: SFP Plus port on CCR-1016-12S-1S RM

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.

Re: Connecting CCR1072-1G-8S+ with TP-Link T2600G-28SQ

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.

Re: MikroTik SFP+ DAC 1m cable - does it support 10G?

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

Re: S+RJ10 Revisions

@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

Re: Actual MTU will decrease after connected

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.

Re: RB3011 and 10GB SFP

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...

Re: Bandwidth Test maximum speed

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...

Re: Can't access OmniTik

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...
