Good day Our DBA's will be upgrading our DB servers to SQL 2016 but will be keeping our existing probe databases running in compatibility mode. Will this have any negative effect on the functionality of NetFlow? Regards, Mat
license count for SFlow and flexible netflow
We are planning to collect sflow from nexus 9K switch and flexible netflow from catalyst 3650 switch. We need to estimate the license count needed. Does the license count for nexus 9K equal the number of nexus 9K physical ports ? We are going to export flexible netflow from each layer2 port of catalyst 3650 switch. Does the license count for catalyst 3650 switch equal the number of layer2 ports ?
Can not generate a PDF
I just installed the NetflowAnalyzer V12, I am on the 30 days trial but I notice that I can not generate a PDF, when I click in the PDF icon a bar appears in the top of the page that says "Generating PDF ..." and a very thin progress bar under the text, this tiny bar completes but the PDF never shows up. There is something missing on the server or in the end station?

Enforcing a Secure Connection
Hey folks! There is an urgent federal mandate that all websites must disable weak ciphers and force TLS 1.2 (disabling lower versions). I edited server.xml and added to the port 443 connector: sslProtocol="TLSv1.2" sslEnabledProtocols="TLSv1.2" ciphers="ECDHE-RSA-AES256-SHA,ECDHE-ECDSA-AES256-SHA,ECDHE-RSA-AES128-SHA,ECDHE-ECDSA-AES128-SHA" (the other SSL parameters to enable it were already defined). This didn't work at all. What am I missing? Do I need to do something with catalina, or on
Mikrotik Trafficflow/Netflow Differs from SNMP by a lot
Greetings, Just getting familiar with Netflow on ManageEngine. As well as trying to sell the purchase of it to Management. I have 2 routers at the ends of a licensed wireless link. Speed differs greatly when I compare the interfaces at each end of this link using Netflow. When using SNMP with as low as 2 second polling the interfaces match 100% when using SNMP with 5 minute polling the interfaces match 100% as well. I have setup netflow on these routers with 64k cache, 1 minute timeout on active
How to display Conversations in NetFlow v12
In Netflow v11.6, I can open the router interface, click on source to display the devices, then click on a device to display all the conversations for that device with details for each session. In v12.1 I can find no where to do this simple thing. I can see all sources, but can't select one. I can see all conversations, but it doesn't allow me to select a single host and provides very few details.
Multiple network interfaces
Is it possible to use netflow analizer with multiple network interfaces (interfaces of host server for network analyzer)? Is netflow analyzer automaticly listening on all interfaces that exist in the Windows system? I didn't see any option to choose interfece in analyzer gui.
New Install Reporting
Just started sending IPFIX data to netflow analyzer. The flow count is increasing. When should netflow analyzer start populating fields within the application on what its seeing?

Does NetFlow showing information of the flow without counting protocol headers?
Hello. I would like to undenstand one point. I'm using NetFlow Analyzer Free edition. Not so much time ago I had a lot of traffic. It was a type of DoS attack where attacker sent me a lot of empty TCP Ack packets (packets without data. Only headers. And it was ack packets by RFC standart so there wasn't been resets of TCP sessions).

We have build 9900 Essentials version of NetFlow Analyzer installed and average between 5k-9k flows per second. I have Count of Top N Records to Store set at 100.

Application Mapping based on IP without port
I've found this question in this Forums since 2006 but no update about this function. I really need this function because I have just on only Application IP list without port since port is random. For example, I have Exchange server IP list about 20 IPs and they don't use standard port as Netflow known. So it shown that Unknown_Application.
Application Mapping based on IP source
Hi, When i analyse traffic under TCP_APP, most entries are made by our reverse proxy. I would like to extract this traffic out of TCP_APP. Because there are lots of various ports, i would like to define a rule where every sessions made by the reverse proxy is plain HTTP traffic. In other words, Application mapping works with a TCP/UDP port but not based on an IP address. Is there a trick to do that ? regards

NetFlow Analyzer cannot see my router. Is multihomed PC not supported?
Trying out the NetFlow Analyzer for the first time and it will not see/recognize my router. All I get is: "No device is currently exporting NetFlow / sFlow packets to NetFlow Analyzer." My router is a Cisco 2920 with IOS 15.0(1)M3. I've gone thru all the steps to enable netflow on the router and verify that it's working via the "show ip flow export" command, which gives my source and destination addresses correctly and tells me this... #sh ip flow export Flow export v9 is enabled for main

Netflow - Source/Destination appearing as 'Others'
Hey guys We've got netflow traffic coming in on our newly built v12 probe, however the traffic is appearing 'Others' - similar to the 'Unaccounted' issue on v11. I remember the fix for v11 'unaccounted' issue we had to copy the bcp files over into the Netflow/bin folder. Is there a similar fix for this? Please see screenshots for more info on error. Cheers, Mat
