VPC Traffic Mirror Session Error

Question

I'm confused about what is required to setup a traffic mirror session.  I haven't seen any specific dependencies for instance type or funtion etc.  When I assign the mirror source I get an error the reads "eni-xxx must be attached to a supported instance".  I have tried connecting this to different virtual nics and instance types and have recived the same results.  Any help would be greatly appreciated.

Hello,  
  
thank you for sending this message.  
  
I see you are having some trouble with traffic mirroring, so this link below will guide you in doing so step by step : https://docs.aws.amazon.com/vpc/latest/mirroring/traffic-mirroring-session.html   
  
Looking at the error you provided, there’s a possibility that you might have used an unsupported instance type. Traffic Mirroring is not supported on the following Nitro instance types :      
     
\[1]  *n.metal  
\[2]  u-*.metal  
\[3] p4d.*
