New vendor for Netflow

New vendor for Netflow

Dear team,

I tried to monitor Eltex(vendor name) router on NetFlow. But looks like there is issue with monitoring bcs NetFlow doesn't know how to work with devices from this vendor.
Issues: I cannot open device summary, NetFlow cannot collect data about interfaces via SNMP 

Could you please advise, what process if I want to add this vendor to monitor it correctly on NetFlow?

Thank you,
Best regards
