You can monitor the logical port activity for example, to troubleshoot network congestion and packets being dropped


Verify that a logical switch port is configured. See Connecting a VM to a Logical Switch.


  1. From your browser, log in to an NSX Manager at https://nsx-manager-ip-address.
  2. Select Switching > Port from the navigation panel.
  3. Double-click the logical switch port to monitor.
  4. Click the Monitor tab.
  5. Select Begin Tracking.

    A port tracking page opens.

  6. Start monitoring activity on the logical switch port.

    You can view the bidirectional port traffic and identify dropped packets. The port tracker page also lists the switching profiles attached to the logical switch port.


For example, if you notice dropped packets because of network congestion you can configure a QoS switching profile for the logical switch port to prevent data loss on preferred packets. See Understanding QoS Switching Profile.
