Problems with ASA 5520 netflow results :(
http://www.networking-forum.com/viewforum.php?f=35 Dear brothers, I have the first diagram like this: [img]http://i2.upanh.com/2013/1007/02//57728522.capture1.png[/img] I configured netflow commands on the routers and built a netflow collector inside.

Alert Profiles - Low traffic threshold
Hello, I would like to know if there is a way to set an alert system to trigger when traffic on an interface goes *under* a threshold, not just when it's exceeding a threshold. This also would help investigating some kinda network problems. We're using v.7.0 b 7002. Thank you Flavio
Change router's IP address in NFA
Hi all, I'm about to change the source IP address that a router uses to export flows to NFA via the "ip flow-export source" command. If I just make the change on my router, NFA will see a "new" router appear on the new IP address - I don't want this to happen. I don't want to lose the history I've accumulated in NFA or any settings/reports for that router, etc. Is there any way in NFA I can change the IP address of a router to match the "ip flow-export source" command? many thanks, alec --

ManageEngine NetFlow Analyzer Performance tuning steps
We all know that NetFlow analysis product are resource intensive as it parse the flow records received every second , the product should be tuned in a such a way that it accommodate all the flows received and generate accurate stats.

Reversing traffic directions on interface
Our router (Cisco 1921 ISR G2) is configured to export netflow 5 to a server running ManageEngine Netflow Analyzer. Our LAN facing interface (g0/0) is reporting traffic just fine, but our WAN-facing interface (g0/1) is not reporting anything. doing a "show ip flow export" reveals that flows are being performed by both interfaces. Is this because netflow 5 only supports ingress traffic, and ManageEngine is merging the two traffic reports? What ultimately need is to reverse the logic in the way that

Unaccounted problem (Raw Data - Aggregated Data)
I have a problem, and I believe is related to raw data. The report "source" presents lower values for greater periods. At the "raw data settings", the space is set to 1 day, but the suggestion is for one hour, based on my flow rate. I realize that even before one day, the troubleshoot report does not provide data. Only show for period very close, like 2-3 hours. This may be causing problems in the aggregate data? At what time the system processes the "raw data" generating the "aggregated data"?

When I run a consolidated report on either of our ASA firewalls, most of the traffic in all categories (Application, Protocol, Top Source, Top Destination, Top Conversation) appears in the last line called "Others". We would like to find out how most of our bandwidth is being used. Is there a way to find out what traffic is being labeled as "Others"? Thanks. -Glenn.

Show full IP group name
I have Netflow Analyzer, build 9800, installed. Our client have long names for the IP groups. Is there a way to not show the names truncated with a ... at the end, but rather the full name on the pages and Reports? If not, we will have to change the name to a shorter format. How can we change the name of an existing IP group without the need to delete it and recreated it? This will cause us to loose all existing stats for the IP group. Thanks Ryno
