We are evaluating NetFlow Analyzer 4, I have set it up to receive flows from 3 interfaces of my 2621XM: S0/0, FA0/0, FA0/1 and enabled IP CEF and other commands as in the manual. In the client window I can see 4 interfaces, 2 with IN traffic and 2 with OUT. I know how to rename them but how do I know what they are ? They named as lfindex5 .. lfindex8 And why they are separated to IN and OUT ? And Why I have 4 of them ? Thanks!
