How to pre-provisioned N2K FEX(N2K-C2248TP-E-1GE) with Nexus 9372

Question

HI Team,
Kindly assist for pre-provisioning the N2K(N2K-C2248TP-E-1GE) FEX with Nexus 9372.
Tried using the below commands just similar to/with Nexus 5K, but no luck with Nexus 9372
In case of 9K,
Nexus 9372# sh fex
  FEX         FEX           FEX                       FEX              
Number    Description      State            Model            Serial    
103  Row C_Rack11_N2248TP                Online   N2K-C2248TP-E-1GE  
105  Row D_Rack10_N2248TP                Online   N2K-C2248TP-E-1GE 
Nexus 9372(config)# slot ?
*** No matching command found in current mode, matching in (exec) mode ***
  <1>  The slot number (aka module number)
Nexus 9372# slot ?
  <1>  The slot number (aka module number)
In case of 5K,
Nexus 5548(config)# slot ?
  <1-199>  Enter a slot number

Hello GN
2248/2224 FEX does auto-negotiate speed to either 100Mbps or 1000Mbps depending on what the far end is advertising. For duplex, the FEX only supports full duplex.
So if you hard code speed to 100 on the FEX and auto-negotiating on the far end, the far end autonegotiating device would do 100/half.

TDR is not supported on any interface on the Nexus 5000 and the message you see when you try it for FEX interfaces is misleading for sure.
