CSS610-8G-2S+IN No Link on SFP+ with Intel X520

[heymrdj]

Just as a useful tidbit. Hate to tell you this, but SFPs are not as universal as the SFP people would like you to believe. Some devices are VERY picky about SFPs (HP switches come to mind - I know there are others). Best bet is to use the SFPs that are recommended by the manufacturer of the device you are going to use them in. Will save you a lot of headaches. If you happen to have inventory of some particular SFP and you try them in some device and it works - great. If it doesn’t, move on with a specified SFP.

As my support ticket shows, even after buying the official Mikrotik SFP, the port still would not come up. Only works with my single Cisco Passive DAC cable. Strangely enough, my Dell and HP switches have no issue with the Mikrotik DAC. If you have a switch with vendor lock, this may be an issue. But it’s not nearly as common these days. This is crappy hardware and firmware QA by Mikrotik, no other reasons need be found.

Very occasionally it’s due to actual hardware and not just assholes in marketing…

Have you sent your 610 back for warranty yet?

Yes, waiting to receive my new one. Mikrotik has drug this out with the vendor taking two weeks at a time to reply.

After a long wait and Mikrotik still dragging their feet for an RMA, wanting to try 2.14 even though the case has been open for months, I finally got a new switch, and it has resolved the issue. The new switch arrived with SwOS Lite 2.12 just like the old switch. I was able to successfully test my active DAC cable, passive DAC cable, and 8 different fiber SFPs, which I was not able to do on 2.12 before (only the passive DAC cable worked and nothing else). Management over SFP+ did not work. I upgraded the switch to the current 2.14 release, and then management access over SFP+ worked, as well as chassis temperature. Everything seems to be functioning as it should, so there was definitely a physical issue with the last switch, not just a firmware issue.

I’ve just installed v2.14 firmware on my CCS610-8G-2S+IN and now my Intel X700 series cards work well with DA cables!

I had the same issue with CRS305-1G-4S+IN
Reset the switch, upgrade the RouterOS to the latest version: 6.48.4, modify the interface settings:

Auto Neg. - off
Speed - 10G
Full duplex - on
Tx Flow controll - on

I tested with long time ping and full bandwidth (10 Gbps) upload and download at the same time.

On my side the bug may be in the auto negotiation settings in the SwitchOS, so may the same happened there, unfortunately there are no RouterOS, but now it is the v2.14 SwOS

I have a CSS610-8G-2S+IN which was working perfectly on version 2.12 Switch OS that it came with.

Regretfully, I upgraded to 2.14 Switch OS Lite and now my SFP ports show they are linked but I cannot connect to them and they do not show up on my network.

I am a bit lost as to how to downgrade. Where can I find 2.12 Switch OS to revert back to what it came with? I tried a reset, holding down the reset button for a few seconds while powering up. It still shows 2.14 Switch OS Lite

Also, once I have the link to the old version, do I install it by clicking the upgrade button or restore from backup?

I’ve found firmware 2.14 to work fairly well, it seems to have resolved all of my previous issues with the SFP+ interfaces.

But to downgrade, you’ll have to go back through this thread to find some download links to other “rc” firmware files. Download one of those, then upgrade your switch using the web UI “Upgrade” tab and the “Manual Upgrade” section by clicking the “Browse…” button, selecting your firmware, then pushing the “Upgrade” button at the bottom of the screen (not the “Download & Upgrade” button).

I don’t think the 2.12 version is published in the normal upgrade page URLs found here: https://mikrotik.com/download
Hence, you’ll need to find a download link in the forums. Sadly, it seems at least some of the download links which went to Microtik’s “box” file service are now broken or Mikrotik have deleted the files. Also sadly, technically the Mikrotik EULA prevents others from sharing Mikrotik firmware. You might try opening a support ticket directly with Mikrotik.

Does anyone still have V2.12rcX that same originally with this switch? It’s the only version that works with my SFP’s

CSS610 switches have built-in backup SwOS firmware which can be loaded in case standard firmware breaks or upgrade fails:

• Holding Reset button for few seconds while CSS610 is booting resets configuration and loads backup firmware SwOS “2.XXp”.
• After loading backup firmware SwOS “2.XXp” it is possible to connect to 192.168.88.1 using web browser […].

Unfortunately, when I press the resets switch on power up, it simply clears all my settings and loads 2.14…..

My issue is resolved. The software that originally came with the switch V2.12rcX is in fact the only that that works with my SFP’s

Here it is if anyone can’t afford to be down for 6 days while waiting to get it from techs
