You can configure IPFIX profiles for switches.


Verify that Manager mode is selected in the NSX Manager user interface. See NSX Manager. If you do not see the Policy and Manager mode buttons, see Configure the User Interface Settings.


  1. With admin privileges, log in to NSX Manager.
  2. Select Plan & Troubleshoot > IPFIX.
  3. Click the Switch IPFIX Profiles tab.
  4. Click Add to add a profile.
    Setting Description
    Name and Description Enter a name and optionally a description.
    Note: If you want to create a global profile, name the profile Global. A global profile cannot be edited or deleted from the UI, but you can do so using NSX-T Data Center APIs.
    Active Timeout (seconds) The length of time after which a flow will time out, even if more packets associated with the flow are received. Default is 300.
    Idle Timeout (seconds) The length of time after which a flow will time out, if no more packets associated with the flow are received (ESXi only, KVM times out all flows based on active timeout). Default is 300.
    Max Flows The maximum flows cached on a bridge (KVM only, not configurable on ESXi). Default is 16384.
    Export Overlay Flow Setting that controls whether the sample result includes overlay flow information.
    Sampling Probability (%) The percentage of packets that will be sampled (approximately). Increasing this setting may have a performance impact on the hypervisors and collectors. If all hypervisors are sending more IPFIX packets to the collector, the collector may not be able to collect all packets. Setting the probability at the default value of 0.1% will keep the performance impact low.
    Observation Domain ID The observation domain ID identifies which observation domain the network flows originate from. Enter 0 to indicate no specific observation domain.
    Collector Profile Select a switch IPFIX collector that you configure in the previous step.
    Priority This parameter resolves conflicts when multiple profiles apply. The IPFIX exporter will use the profile with the highest priority only. A lower value means a higher priority.
  5. Click Add.
