NetFlow nf_input_snmp index ?

[utahbmxer]

Hi

Trying to work with netflow data that I am sending to Graylog.  I want to separate it into streams so I can work with it easier, etc.  Is there a way in the firewall (gui or CLI) that I can see what index number for nf_input_snmp matches the actual interfaces?  I have a lot of VLANs, so I want to make sure I am getting it right.  Thanks in advance!
