Resolution

Steps to resolve
For 3.2.0 and higher

Recommended Action:

Check the physical NICs' status of uplinks on hosts.

1. In the NSX UI navigate to "System | Fabric | Hosts | Clusters" or "System | Fabric | Hosts | Other Nodes" or "System | Fabric | Hosts | Standalone".
2. In the Nodes list of specific cluster or "Other Nodes" tab or "Standalone" tab, check the Status column. Find the Transport node with the degraded or down Node Status.
   
3. Select "<transport node>| View Details | Monitor". Check the status details of the PNIC/BOND which is reporting degraded or down. To avoid a degraded state, ensure all uplink interfaces are connected and up regardless of whether they are in use or not.
