C9400

[khatarykhattari]

We are going to buy a Cisco C9400 with C9400X-SUP-2XL supervisor which has 4 10/25G ports and 3 40/100G ports.

we want to use the three ports with 100G as 10G only, so i wonder if it's possible and what do we need exactly ? to use SFP+ transeiver module in place of QSFP28 ??

thanks in advance

I do not believe there is a way to convert 100 Gbps down to 10 Gbps. 

There are converters that can go down to 25 Gbps.

Exactly what line cards are planned to go with this chassis?  

[khatarykhattari]

This conversion will be done on the 100G ports of the supervisor as we only need 10G ports. for line cards, we have C9400-LC-48T, C9400-LC-48S and C9400-LC-24XS.

C9400-LC-24XS can support either SFP or SFP+.
