    Netflow configurator, problem

    bora.

      Hı,

       

      l got a below error message when l used netflow configurator.

       

      Which Cisco device does Netflow Configurator support ? How can l resolve this problem?

       

      Thanks,

          Só I think you can contact cisco support. Or show this information in cisco foruns.

          May be you need to do upgrade in firmware.

            I think it might be easier if you say which model device you are trying to use netflow on.  From my understanding it supports a lot of devices.

                lt is cisco 2960c switch

                    That model does not support/does not have NetFlow.

                    Here's a list of Cisco devices that support NetFlow:

                      That particular switch does not support netflow.  It usually requires layer 3. You can tell if a cisco device and software that it has supports netflow if you type: show ip flow export. 

                       

                      Switch:

                      3750#show ip flow export

                      Flow export v9 is enabled for main cache

                        Export source and destination details :

                        VRF ID : Default

                          Source(1)       10.x.x.x (Loopback12)

                          Destination(1)  10.x.x.x (2055)

                        Version 9 flow records

                        0 flows exported in 0 udp datagrams

                        0 flows failed due to lack of export packet

                        0 export packets were sent up to process level

                       

                       

                       

                      Nexus5548# show ip flow export ?

                                                ^

                      % Invalid command at '^' marker.

                      ?

                                                ^

                      % Invalid command at '^' marker.

                       

                      5ks can do netflow, they just have to have a certain module installed that I don't have.
