Ubiquiti RJ-45 SFP+ module shows up as multimode fiber in SwOS 2.10

I've fitted a Ubiquiti RJ45 SFP+ module to my CSS326 running SwOS 2.10. This SFP module works but comes up as "multimode fibre" and shows no temperature details.

This is more of an FYI for Mikrotik than a specific complaint.

Re: CRS326-24G-2S+RM able to switch 10Gb/s at wire speed?

I will prefer this one Ethernet/SFP+ (Combo Ports) CRS312-4C+8XG-RM
No good for me; I use too many of my 1Gb/s ports. The CRS326 is perfect for my needs.

CRS326-24G-2S+RM able to switch 10Gb/s at wire speed?

I have been relying on a CRS125 for about five years but I'm getting to the point where I need a couple of devices to have 10Gb/s connectivity on my LAN. In my example I will have most devices on the network connected to the 1Gb/s ports but my PC and my file server will be connected to the 10Gb/s po...

Re: Making a mirror port totally unable to communicate

Well it seems that as usual there's zero information on this and nobody able to assist.

I resorted to mucking about with my network sniffer hosts to stop them ever attempting to obtain an IP address on that interface. It's a hack, but it is what it is.

Making a mirror port totally unable to communicate

I have a CRS125-24G-1S with one of the ethernet ports set as a mirror destination that captures traffic from interface 25 (switch1-cpu). Essentially, this captures traffic as it egresses through the router to the Internet (plus it also captures the traffic after it has passed through the CPU and bac...

Any known issues with power consumption using these in a CRS125? The supplied power supply is 12v 2.4 amps I believe. I have a CRS125-24G-1S so there's no WiFi.

I have a CRS125-24G-1S which I just updated to Routerboard firmware 3.41 and then RouterOS 6.41.3. The System-->Routerboard menu is now saying that there is a new firmware version "6.41.3" available.

Re: Huawei E8372 not appearing as LTE interface

I can confirm this problem was resolved by - wait for it - turning my router off and on again.

Reboots didn't help.
Software upgrades to Release Candidate didn't help.

Turning the router off by pulling the power cord was the solution.

I do some alternate routing marks via pre-routing that don't work well with fast-track and make sure that I only fast-track connections with connection-mark=no-mark and routing-table=main.

Re: How do I bypass fasttrack for one connection

Is the connection always initiated from the lan side? If you have port forwards and the connection is incoming you may need to use dst-address as the filter on the fast-track. Also, when you change the rule, any current connections will still be fast-tracked until they drop off. The connection is o...

Re: How do I bypass fasttrack for one connection

Thanks. I'm currently operating without fasttrack and the CPU hasn't spiked over 50% so far. At least that means I have a workaround.

Nope, flag S sets also for standalone and master ports if they are part of bridge. Well that would make sense because it makes them the same L2 network.

There is nothing wrong with bridge. Ports 2-5 are in same L2 network only when configured as master/slave. In this configuration they are are standalone.

Master/Slave just controls interface isolation, and as I understand it link bonding basically just stops spanning tree from going nuts for starters, and then balances traffic as a second function.

Your bridge configuration is wrong and is causing your DHCP server to be exposed to the Internet interface where your cable modem lives.
