Is it possible to rebuild/restore/reset the application and protocol mapping tables?
Hello all, In the *COMPLETELY HYPOTHETICAL* event that a recently migrated Netflow installation resulted in a corrupted application mapping table, is there a way to restore *only* the associated tables to the factory default IANA port/protocol mapping list without a complete re-installation? Thanks, Chuck

Custom Source and Destination Reports / Netflow Analyzer
I am currently evaluating your product for the monitoring of Netflow data; to replace MARS as a netflow analyzer. Source and Destination reports should be customizable within an IP Group to exclude either the source or destination of the IP Group. This way to can get more than just interface utilization when you have high traffic within a /24 IP group. Example: Created IP Group [HOSTING] 10.255.255.0/24 Check IP Group Report Destination for Popular IP Check Source for Popular IP Since the IP Group

Extreme sFlow source address
Extreme allows you to configure an sFlow agent IP address. According to the Extreme documentation this address is stored in the payload of the sFlow data. In theory NFA should be able to pull that address from the packets and use it as the source of the sFlow data. However, NFA uses the source address of the sFlow packet it receives as the device it maps the data to. Because of this behavior if the interface the sFlow originates from changes, then NFA treats it a coming from a different device. This

Netflow packets traffic and disk space for NetFlow Analyzer
Hi, we install NetFlow Analyzer for trial 12.03.2013 and today check disk space at NetFlow Analyzer server. Directory /usr/local/NetFlow has 377230 Mbytes and directory /usr/local/NetFlow/pgsql has 377063 Mbytes or ~375 Gbytes. But when we check a total traffic of netflow packets for this period, we see only ~45 Gbytes incoming to interface NetFlow Analyzer server. Can you explain this difference between real traffic volume and size of pgsql database? Why for store 1 GBytes netflow packets is required
Netflow Packets being received but interface counters not updating; Cisco ASA & NFA
Greetings, We are using NFA to monitor flows from our Cisco ASA installations. We recently updated one of our ASA 5510 to 8.4(5). After doing this we are no longer getting interface statistics. I verified with wire shark that we are still receiving netflow data to the NFA server, and I can see netflow packets being received in the interface view. Yet we are seeing no statstics for traffic in / out. Any pointers or things to try are greatly appreciated.
