@itimo01: Did you really read my post? 2.5 Gbps is working with both modules. But it is not possible to select 5 Gbps on SwOS. SwOS 2.5G.png According to the release notes, 2.5 G was added in version 2.16. Perhaps someone from Mikrotik can comment on this officially? BTW: RouterOS is too complicated...

Hello, With the availability of Realtek RTL8157 based USB network adapters, which can reach 5 Gbps, the problem now arises that under SwOS 2.17 (CRS309 / CRS317) this speed cannot be selected and auto-negotiation unfortunately does not work either. I have tested all possible combinations. If both th...

At first it looked good, but after about 2 hours I had the same problems again. After another 6 hours or so, these problems became more frequent and I had to go back to version 2.14. It seemed to me that it had something to do with DHCP (with fallback). But even with a fixed IP, I had the same probl...

Two weeks ago I tried again with v2.17 and the adjusted LACP settings. After about 2 hours the same behavior again. i.e. back to version 2.14. Yesterday evening I upgraded to the latest version 2.18. Again I noticed the sporadic interruptions on the pfSense side, but somehow shorter. OK, back again ...

I can't find anything about LACP changes in the release notes. I have already adjusted the LACP hash algorithm on the pfSen...

I didn't change anything in the configuration after the update to 2.17. Since downgrade everything is running fine. No errors, no log entries,...

I have problems with SwOS v2.17. From the looks of it, ICMP packets are lost. I had to go back and downgrade to version 2.14. This version runs without these problems. My CSS610 is connected via LACP (active) to a pfSense 2.7 (Fast mode, Layer 2,3,4) on a Supermicro X11SCL-iF board. Since the update...
