MS510TXUP compatibility issue with Mikrotik RB5009UG+S+IN via SFP?
I think that my MS510TXUP is not compatible with MikroTik RB5009UG+S+IN when connected via SFP port. The issue is this: When I connect my RB5009UG+S+IN via any SFP connection cable I have to MS510T...

Reads to me like STP is blocking the port virtually as the connection does come up.

....some kind of loop in the network, the Spannng Tree Protocol - on either one or both sides - is blocking/shutting the port in the test set-up I'd suspect.

Also I think the log with same timestamp can be out of order. And apparantly, at the exact timestamp of "2021-12-04T17:53:10.144-8:00Z" there's also a link up and link down event. All three cannot be happening at the same time if that's STP causing connection status change.

OK, makes sense.
The issue reminds me to some issue we've (nah, not Netgear) experienced on an SFP+ based network link on two security appliance/router brands, and I think the customer tried some Mikrotik with an SFP+ garage and a similar set of test switches as yours. One of the discoveries was that the router side flapped the links, and did not allow using short/passive DAC.
However, you have tried industry standard fiber modules and experienced the same.
I would suggest to file a support case with Netgear, convinced their switch engineering would be keen to look into this.
YeZ can you assist to establish a link to the switch engineering?

Thank you schumaku.
Yes I've even tried Gigabyte SFP adapters and they don't work too. And only between RB5009 and MS510TXUP.
If there's anything else I can help provide, please do let me know.
I've just managed to create the factory reset environment again and did a minimal system test, and this is the logs I got:

This is from two times I tried to cycle the port on RB5009. It might be hard to see, that the first time (at 2021-01-01T00:04:14.590Z) the switch did not even consider the link is up and directly considered the link to be down. And the second time (at 2021-01-01T00:04:15.610Z) the link was up for a very short moment and again, two link down happened.
Above log is captured with Debug level and not skipping anything, just so it might help with debug. I have the full log available if needed.

Also please instruct on how to open a support case - the MS510TXUP is past the 3 month support period and on the support site it directs me to post here for help.
