Cisco nexus 93128TX CVR-QSFP-SFP10 issue

Folks,

 

I have cisco nexus switch 93128TX (running version nxos.9.3.4) with M12PQ GEM module. I want to terminate 10G fiber on it so i bought CVR-QSFP-SFP10 adapter from fs.com https://www.fs.com/products/72582.html 

 

Now cisco saying i have to configure speed-group range to turn 40G to 10G port and port range has to be 1-6 & 7-12 so on port e2/1 i set speed-group 10000 and it accepted my command but then i noticed following in my show interface output and don't know what is wrong here. does that means fs.com adapter not supported on cisco nexus 93128TX?

it stuck in (check speed-group config). my port isn't coming up somehow. do you think fs.com isn't supported or i am missing something here (i did run service unsupported-transceiver command also)

Hi,

fs.com products usually work fine with Cisco equipment. Also, the fact that you see this shows the port is working.

 transceiver is present
    type is QSFP-40G-SR4
Can you try a different port like 1, 2 3, etc..?

This switches isn't in production so i have tried every single port also i have changed M12PQ to M6PQ GEM to just avoid strange 8 port limitation on this platform.

 

I have added speed-group command only on first port e2/1 hope that is correct way to configure. one more question why my above output showing 40G SR4 instead of 10G SFP? 

type is QSFP-40G-SR4

Is this the exact part number for the module?

N9K-M12PQ

If yes, I don't see  CVR-QSFP-SFP10 listed in the comparability list.

You can also contact fs support team to make sure this is what you need.

Its listed and showing you when you hover mouse on icon that CVR is required. not sure if i am reading it wrong. i did contact them and they are trying to test in lab but this is kinda urgent for me.. i have order cisco original QSA module so lets see if they work or not.

Wow, so the issue is with fs optics. If you work with fs's support, they will resolve this issue on their side.

This is great. Thanks for the feedback!
