Hello,
After upgrading to routerOS v7.8 my sfp stick doesn’t work anymore. Not recognized at all. Before it was working fine with Autonegotiation on
Same issue in http://forum.mikrotik.com/t/v7-8-stable-is-released/164757/1 post.
Here are more details:
Hardware: RB5009UPr+S+
sfp+ stick: 6COM 6c-SFP-10G-T SFP+ 10G RJ45
Now i’m using S-RJ01 stick as backup with performance limited to 1G.
I’ve ordered S+RJ01 and is on the way.
Thanks for your help.
The same has happened to me in my 5009.
Was running ok for a year, but after upgrading to 7.9 i have not even been able to recover the functionality of the SFP+ by now downgrading to 7.7, and after having passed to 7.10beta.
The SFP appears as no link, and for example, the dhcp client that makes use of it marks the SFP+ as stopped.
Any ideas ?.
It’s like that device was marked inoperative now…
Tks!
Forgot to mention, this got fixed asap in the next release. Thanks.
I know you are the author of the post 
, but it wasn’t fixed for everyone. As you can see here http://forum.mikrotik.com/t/routeros-v7-bug-on-ros6-working-unrecognized-10gb-sfp-dac-direct-attach-cable-copper-pigtail/176197/4 it still bugs for another users and the only way is to downgrade to version 6.
