Resolution

Steps to resolve
For 3.2.0 and higher

Recommended Action:

Check the physical NICs' status of uplinks on hosts.

• In the NSX UI navigate to "System | Fabric | Hosts | Clusters" or "System | Fabric | Hosts | Other Nodes" or "System | Fabric | Hosts | Standalone".
• 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:

 

• 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:

 

Note:
The Admin Status is the only portion of the output that ESXi controls. 
The Link Status column specifies the status of the link between the physical network adapter and the physical switch.
