40G to 10G C9500

Hi,

I have a switch  C9500-16X and want to downgrade 40G port to 10G port. I have installed cvr-qsfp-sfp10g in 40G port of switch and  SFP-10G-SR-S in cvr-qsfp-sfp10g. Following is the output of "show idprom interface fo2/1/1"


Switch#show idprom interface fo2/1/1

Is there any special commands  for SFP-10G-SR-S to install in cvr-qsfp-sfp?

Thank you so much.

Link is not coming up. SFP-10G-SR-S inserted in CVR-QSFP-SFP10G. 

Link not coming up other possible issues.

1. check the patch cable ? what cable you using ?

2. are you able to see SFP recognised show interface x/x trans

3. what SFP other side ?

4. can you post bot the side configuration and show run interface x/x and show interface x/x

At both ends SFPs are same "SFP-10G-SR-S".

We have tested the different cables.

is there any command for the the interface having  SFP-10G-SR-S and CVR-QSFP-SFP10G?

Full-duplex, 40Gb/s, link type is auto, media type is unknown

shows as unknow, until you see as SFP, you will be not able to use that port.

as i remember 17.3.5 has fixed this issue, i am sure i tested on these ports.

May be @Leo Laohoo  suggested some bug, worth looking also remove and default  the interface and re-insert and test it.
