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.
I can confirm this is not the case. Three reasons:
1) I do have RSTP enabled for the whole network.
2) When tried with factory reset environment, there's nothing else connected except this only one piece of link between the router and switch.
3) The shutdown of port is not reflected within STP status page of MS510TXUP. If I create a loop, it would show such in the status page on either side. This means the port gets disconnected somehow, then STP jumped in to mark the port disabled, just like I pulled the plug on the port.
