NFA not using the timestamp fields
I'm developing an implementation of Netflow in a switch. Anyway I'm using Netflow Analyzer to "validate" my work and check if my netflow export packets are correctly formed. Everything works just fine, but I have the impression that Netflow Analyzer ignores the timestamp fields of my packets. Let's take an example: Imagine a continuous flow starting at 00:00. After 30 minutes, the flow is exported because of the "active timeout". The start timestamp of the netflow export is 00:00 and its finishing
router not showing up
My router is not showing up in the dashboard. I have verified that netflow is configured properly and flows are being exported via these commands: show ip flow export show ip cache flow No firewalls are blocking the traffic. I'm actually receiving flows from other routers already. It's just this new one I configured is not showing up. Any ideas? tcbonline

sFlow Early release Trial
Hi, I was invited to try the sFlow early release but can not get it to recognize the flow coming from my switch. We have an HP 5406zl I have enabled sflow on all ports and, when I sniff the network , I can see the sflow packets on the network. I am using a 2003 Server running in a VM - clean build - with opmanager as the only other major service running. Netflow says "No Router is currently exporting NetFlow packets to NetFlow Analyzer." Where do I look next? Mark

Netflow Buffering
Do Cisco devices buffer netflow requests? For example, if I need to reboot my netflow collector, would I lose any flows during the reboot cycle?

Change port 8080 to 80 on Linux version

Extra managed interfaces
I have five Cisco routers (some outsourced) exporting flows to NetflowAnalyzer from various interfaces. I have unmanaged the interfaces I am not interested in. I just connected to look at the devices and I noticed that one router had suddenly added extra managed interfaces called Virtual-Access2 through 12. Where do these come from? Is there any way to stop them? Alternatively, can I have them so that they are added into NetflowAnalyzer as unmanaged.
"Others" Network Traffic
Hello, I am looking into traffic usage on Netflow Analyzer and when I view "Source" or "Destination" A large percentage of traffic appears under the section "Others". How can I get a breakdown of what IP's are in this "Others" group? Thanks!

Application report protocol filtering
I am using the latest copy of NFA on Fedora together with fprobe. I have created a port mirror so all data going to/from a site router is sent to my Fedora server. The site router is configured not to forward netbios traffic but there is still a lot of netbios traffic going to the router so NFA is displaying it in the Application reports. Is there a way I can filter out the Netbios traffic from the reports so I can get correct WAN utilisation traffic? I am doing this way as I do not manage the router

Need to monitor multiple interfaces on router/switch
I have added a router for NetFlow support, however, I have a need to monitor multiple interfaces. It appears that it is not possible. Is that true? If not, how do you go about accomplishing this? For instance, if I try to add multiple instances of ip flow-export source <interfacename>, it will retain the last entry I entered. Thanks, Dan

Monitor multiple interfaces on one router
Hi, I have set up my router with the ip route-cache flow on both interfaces i want to monitor, on version 5.5.0, build 5505 when i add the ip flow-export source (interface) it will only show the the last entered interface, it will not allow me to have both G0/0 and G0/1. So subsequently i only receive the data from one interface at a time, until i go back and manually change the configuration on the router, definitely not he optimal solution. i have tried entering a secondary destination by adding

Problems
Hi @ all, we've downloaded the trial version of the Netflow Analyzer 5.5.0 Build Nummer : 5503. I have configure various Router to send the sflow traffic to the Netflow Analyzer instead of our other sflow software. But I still have 2 problems : 1. How can I delete Routers which doesn't send sflow data anymore? 2. In all report graphics i can't see the actual 10 minutes. So the scale goes to the actual time e.g. 15:00 but the trafficgarfics goes only to 14:50. And there was traffic between 14:50 and
