Are you running this from the same machine that has NPM and NCM installed? The reason I ask is, are you sure you have SNMP access from the client to the network devices?
Yes I am running the NetFlow on the same computer that is running the NCM and NPM.
I just got confirmation that there is a bug when using the SNMPv3 method. We do not currently have a fix scheduled for this.
The only way to use the tool would be to change from SNMPv3 to v2 and run configuration, then change back to v3. I realize this is not really helpful but unfortunately that is the current limitation of the free tool.
ok I am having same problem ronald is having so I need to use snmp2? then switch back to snmp3? I tried snmp2 and I am getting same error ronald is getting pls help. also I am testing the 30 day eval on my system at home very basic setup comcast modem, to linksys router, how do i set an snmp string or do i need to? tested at home not working there either pls help.
The device has to support SNMP and NetFlow. The device also has to allow the configuration of NetFlow via SNMP. If it does not support it, you will have to connect via telnet and configure it manually (or use the device's web UI to configure it). What is the device you are trying to monitor?
our network traffic is going through a CISCO PIX 525 PIX VER 7.0(4) I just googled netflow and cisco pix 525 it seems pix 525 does have netflow protocol, how do I verify that or turn it on if its off? and where do I see the snmp string? I have access through the browser or ssh, you metioned telnet? more info I just used the cisco asdm to get to the pix through asdm, where do I add the entry for snmp and or netflow?
You should be able to telnet to the device. Specify the read-write community string in the configuration mode (see help for command "snmp-server", for example snmp-server community private rw). Netflow export can be configured from the console too, in case the NetFlow Configurator does not work well. See "ip flow-export" command (http://www.cisco.com/en/US/docs/ios/12_1/switch/configuration/guide/xcdnfc.html) for more info on how to do this.
telnet shutdown ssh enabled more secure its the same thing but more secure, the asdm browser gui has a command line utility, I did a sh run these entries are already there: pertinent information changed to be secure

I did not find any flow commands i think this might be the problem why its not working,
I did a show ip cache flow command got error invalid input detected at marker.
I checked the cisco link, it has a lot of examples. can you give me a real simple one to get this going? is there a command just to turn it on?
This looks like a real example, although I don't really know specifics of your device commands: http://itknowledgeexchange.techtarget.com/network-technologies/how-to-configure-asapix-firewall-to-collect-net-flow-data-from-an-external-router-to-the-netflow-collector-located-in-inside-network/
I watched the video to set up the netflow
the command is ip flow-export etc....
I get input detected at. so I do not think the pix 525 takes that command?
so the question is has anybody got the netflow analyzer to work with the pix 525?
or better question what network analyzer works with the pix 525?
