The resolution for this issue is to prove that NFA is working as designed by using a third party tool as follows:
1. Download and install Paessler SNMP Tester.
2. Run a Walk test with if type 18.104.22.168.22.214.171.124.1.3 to list the if type of all the interfaces
3. Run a Walk test with if description 126.96.36.199.188.8.131.52.1.2 to list the if description of all the interfaces
The test should show whether or not the device itself is producing the information in question.
