Resolution

Steps to Resolve

For 4.0.0 and higher

 

1. Wait for 5 minutes to see if the alarm automatically gets resolved.
2. Ping the NSX Transport node from the Manager node. The ping test should not see drops and have consistent latency values. VMware recommends latency values of 150ms or less.
3. Inspect for any other physical network layer issues. If the problem persists, contact VMware Support.
