      Why is the configuration not working  ?


      Configuring NetFlow

      Information About NetFlow

      NetFlow is a protocol that provides information about network users and applications, peak usage times, and traffic routing. The NetFlow protocol collects IP traffic information from network devices to monitor traffic. The NetFlow architecture consists of the following components:

      • Collector—Entity that collects all the IP traffic information from various network elements.
      • Exporter—Network entity that exports the template with the IP traffic information. The controller acts as an exporter.

      Step 1  

      Configure the Exporter by following these steps:

      1. Choose Wireless > Netflow > Exporter.
      2. Click New.
      3. Enter the Exporter name, IP address, and the port number.
      The valid range for the port number is from 1 to 65535.
      1. Click Apply.
      2. Click Save Configuration.
      Step 2   

      Configure the NetFlow Monitor by following these steps:

      1. Choose Wireless > Netflow > Monitor.
      2. Click New and enter the Monitor name.
      3. On the Monitor List page, click the Monitor name to open the Netflow Monitor > Edit page.
      4. Choose the Exporter name and the Record name from the respective drop-down lists.
      5. Click Apply.
      6. Click Save Configuration.
      Step 3   

      Associate a NetFlow Monitor to a WLAN by following these steps:

      1. Choose WLANs and click the WLAN ID to open the WLANs > Edit page.
      2. In the QoS tab, choose the NetFlow Monitor from the Netflow Monitor drop-down list.
      3. Click Apply.
      4. Click Save Configuration.

          Hello Jorge,

           

          It is not an issue with how you are configuring your device, it is that NTA is not properly getting all required fields for report on NetFlow.  This is a known feature request and I have added your vote to my internal counts.

          Thanks

          Marcus

            I am seeing the same issue and will vote for the NTA/WLC compatibility feature.

              You may need to talk with TAC if you don't find the procedure for your specific model & version of WLC.  Some thoughts:

              • Create an Exporter by entering this command:
                config flow create exporter exporter-name ip-addr port-number
              • Create a NetFlow Monitor by entering this command:
                config flow create monitor monitor-name
              • Associate or dissociate a NetFlow Monitor with an Exporter by entering this command:
                config flow {add | delete} monitor monitor-name exporter exporter-name
              • Associate or dissociate a NetFlow Monitor with a Record by entering this command:
                config flow {add | delete} monitor monitor-name record ipv4_client_app_flow_record
              • Associate or dissociate a NetFlow Monitor with a WLAN by entering this command:
                config wlan flow wlan-id monitor monitor-name {enable | disable}

                  Thanks, rschroeder, after relooking at it I found that I had to click on the WLAN ID and then it showed the screen to add the monitor from the drop down list.

                  This is a 5508 device under NETFLOW but it doesn't show any other information then what I would see under NPM. Under NPM it at least shows all the interface status, under NTA it doesn't even have an arrow to show the interface status. Is this correct for the NTA and the 5508? We are running NTA 4.2.2. If I do have it set right I don't see any additional information under NTA, I get more information from NPM.

                   

                  Thanks..
