Customize Report emails
First off, I am very impressed with the Netflow Analyzer program. I was wondering if there was a way to customize or add text to the email reports either in the email or PDF versions. Thank you,

Measure Volume Of Traffic Between two IP Addresses?
Hi I am trying to measure the traffic over a given period between two devices over a specific link. When i try and create a custom report adnd add these two IP`s as Source And Destination and choose the interface in question, i also then get numerous other IP addresess in the list under IN & OUT traffic. Basically all i want to do is measure the traffic from User A to Server B. Any help would be greatful. Cheers, RH
DOS Attack locks up server
About a week ago we encountered a denial of service attack. The attack consisted of 85MB of continous traffic hitting two of our DS3s that we monitor. In doing this, the server went to a stand still and the mysql process was 100% as it was pushing all this data into the fields. The GUI interface stopped responding during this and for some time after the attack. This lead me to a problem of not being able to find what IP Address they were attempting to DOS. We ended up having to call our ISP for them

Alerting based on anomalous traffic
We currently have offices connected via a service providers MPLS network, lately we have been seeing anomalous traffic coming into our network. Is there a way to configure Netflow Analyzer to alert me when traffic from an unexpected IP comes into an interface. Under Alert profiles, traffic can be defined based on Port or Application. What I need to be able to do is setup alerting based on traffic from IP's outside a defined list.
Google Map - Multipe Devices of One Location
Maybe I overlook but how can I add muliple devices to one location? I can add the devices one by one with the same location name but it shows only one device when I "on over" the pin of the location. Please let me know. Thanks JC
SNMPv3
Is SNMPv3 support a planned feature?
Can Windows XP Professional SNMP be setup to send to Netflow
I have looked under the supported devices and naturally Windows is not listed. However, I have been playing with alot of the settings on the workstation but cant help but think just because it isnt listed, doesnt mean it isnt supported. Has anyone configured a Windows XP Professional Workstation to send traps to Netflow? Thankyou Kelly R.

Importing
Hi, have been loking at your product for a while now and so far think it is excellent, I have one question, we are able to get netflow info from our provider as well as our own router, our router is fine because we set it to which ever collecter we install, our provider stores the netflow for us and we can donload them and look at them but we were wondering if there is a way to import them into the database and view them in the analyzer interface? Thanks in advance
No results to display In Conversation for Ip Groups
When i set a custom time interval of to see the last past 5 minutes, I get the "No results to display" under conversation for my custome IP groups. When i do the same for my interface, i do get data returned, which includes IP addresses in my custom IP group. Why is this?
No OUT traffic being reported?
WAN Uplink 19% IN: 1.51 Mbps 0% OUT: 0.00 - Is this something I am missing in the software configuration, or is this a problem in the router that is sending Netflow data?

Google Maps
Is there any way of stopping the Google Map View option from being displayed on particular users? Is there a way of stopping it displaying for all users? I do not wish it to be used by anyone.
Cannot telnet to Netflow port
I've installed the NetFlow Analyzer and configured the router to export netflow traffic. But i don't see any interface in the NFA dashboard, then we try to telnet from the router to NFA using the 9996 (as configured in NFA) but fail, and then I try telnet from the NFA itself but also fail. I've disabled the Windows Firewall (running on WinXP Pro) on the NFA, but still don't work, I can access the NFA web interface via another computer (port 8080). Why i can telnet to the netflow port? is it normal?
in/out traffic
question about in/out traffic... i put ip route-cache flow on the vlan interface...that vlan interface has incoming and outgoing traffic...why does the netflow analyzer put traffic only on the in traffic?...does the NFA know the different b/w in and out traffic? thanks
Ligne commande sur le routeur
Bonjour, Je n'ai pas de r�sultat dans netflow. Je pense qu'il faut mettre une ligne de commande dans le routeur. Mais laquel ? Merci
TCP_App shown for FTP traffic
We have some passive ftp transfers and they are being resolved as TCP_App, we believe that this is due to the port not being shown as 20. Is this happening at the netflow analyzer end or the information received from the router? Regards Mark
NFA and temp files on /tmp

NAT & Source/Destination IP
Testing and successfully configured NetFlow Analyzer to collect NetFlow and NBAR from our 2611XM. My goal is to get in depth info re internet traffic of LAN IPs <-> internet source/destinations. However, because of NAT on our PIX 515e, packets show only our public IPs, which in the case of workstations is a single [gobal outside] IP address, making the accounting useless for my goal. I was hoping that by monitoring both the outside interface and inside interface, we would be able to see the full
No results to display for IP Groups
I'm in All Devices and select I my router and view Conversations, then I set a custom time selection for the past 5 minutes. I see conversations. But when i click my IP Group with the same time parameters i get the No Results to Display error even though i see the results from the All Device's Conversation.

netflow export on catalysts
Hello Guys, I have exported netflow, so far, only from cisco routers. But I know cisco switches (catalyst) are also capable of exporting netflow. I would like you to help me with some primary questions on that. 1) are ALL cisco switches capable of exporting netflow, including the old ones ? 2) if not all switches are compatible with netflow, can you point me starting in which models i can have netflow ? 3) i know cisco switches have a command-line configuration system very similar to routers.

Net Flow 6
I am just getting started with Net Flow 6 and want to set it up with my Cisco 2811 router. Will it work with 2811 and if so, how do I do this on the router. Our traffic is slow on our PTP Multilink T1's. Cpu usage is never pegged nor is the memory usage. Thanks, Jay

Database Structure for NetFlow
Can anyone give me the specifics on the database stucture ? I do know that MetaTable table has the lookup information of the tables that are out there. What is the Srclf_1H - are these average hourly data ? I am really looking for 5 minute samples. Are the samples taken on NetFlow average or snapshot ?
DNS Lookup hosts file list
Where can I edit the list of name servers so that netflow will resolve all IP addresses across our network. At the moment I get some gaps but when I run nslookup it resolves. Thanks

Graphs now unusable in NFA6
Hi All, Does anyone have this issue, can anyone help us here? We have an issue now where the graphs in NFA6 are not usable. This is a major problem as we need to visually report on traffic. Included in the files below are screen shots of the graph itself, which changes every time you switch the refresh of the screen. Please note that all the data reported is correct, the graphs are the issue. Also included is information on my NFA6 Server, and both of our WAN routers which have this issue. Please
UDP port zero ???
Hello People, Im having some strange data here .... I understand that TCP/UDP ports that has no application mapping created are categorized as TCP_App and UDP_App, no problem on that. THe strange thing is that i'm seeing several ZERO ports on UDP_App report. The strange is that TCP_App correctly shows the ports, but UDP report shows me several zero ports. I was expecting to see lots of random ports. But as we know, there's no traffic on zero port !!! How can this be possible ? Is there a way of 'fixing'

Configuring Cisco 6506 with Sup720
It works fine and I�m impressed about the reporting facility on NFA with my Cisco Internet Routers. I wish to try it out with our Cisco core switches Cisco 6506 with Sup720 with IOS Version 12.2(17d) SXB11a Currently I am using Cisco modular NAM 2 for the monitoring and not really happy with it!!! Can I use the same NFA to monitor both the Internet Router and the LAN Core Switches? Can you help me with the configuration procedures on our clustered Core Switches and if any in NFA?
Difference of traffic graphs
Hello Guys, I'm using NetFlow Analyzer for monitoring a cisco router. Everything is working fine, no problem at all. But .... i have noticed a slight difference on traffic graph generated by NFA and other one generated using normal SNMP monitoring tools. In my case, i'm using cacti for monitoring the same router and graphing Serial traffic. I know there's a basic difference between generic SNMP monitoring tools and NFA. Most all generic SNMP monitoring tools, just like cacti i use and mrtg and several
