ASA5550 - Netflow Analyzer - Interface problem
Hi, i have ASA 5550 IOS 8.2.1 k9 , and NetFlow Analyzer professional Plus version 9 build 9000. Issue is that i cannot see all 4 active interface on NFA . only 0, NULL0 , UserLAN, BranchLAN is shown.

newly disovered interfaces?
Hi I have a router that acts as a VPN sever too. I have very strictly only exported netflow data for 7 of the router's interfaces. The data is analysed wonderfully and it is working flawlessly. HOWEVER Everytime a VPN user connects and a new tunnel is created, it seems that NetFlow Analyzer then picks up the Interface via SNMP, and adds the Interface to the router automatically. NOT the desired result unfortunately Is there any way that I can stop this behaviour, or any way at the very least that

A quick post/note about my experience with switching to the Linux version.
Originally we ran the NetFlow Analyzer software on a 64 bit Windows 2008 server (VM). As with most windows based software packages that deal with a lot of data and correlation it was good, but sluggish. Looking at the NetFlow Analyzer software on our Windows deployment I noticed that some pieces were Unix/Linux software packages that have been ported to Windows. I decided to bring up a 64 bit Ubuntu VM (with the same hardware specs as the Windows VM) side by side with the Windows version and compare
