Environment

HCX 4.x

Cause

The only known method to produce this behavior is to modify the HCX L2E Segment Config from NSX while the segment is stretched by HCX. This will cause the HCX DB to be out of sync with the segment logical-switch config. 

In this example, the extended network segment (Test-11-376..) was removed from cloud/destination NSX T1, and a Service Interface was added/attached to the HCX L2E stretched segment. This caused a duplicate segment to be created with new logical-switch uuid.

Modifying the HCX extended NSX Segment outside of HCX is an unsupported operation. Please refrain from making such changes as it can lead to unexpected results. 

 

Resolution

To recover from this condition, please perform the steps below.

  • Force unextend the affected network
  • Delete the HCX L2E segment from Cloud/Destination NSX 
    • If the NE was in an HA pair, you should unextend all networks stretched by the NE HA-pair
  • Delete the NE (force delete if necessary)
  • Create a new NE
  • Re-extend the network on new NE
    • If using NE-HA, re-create the HA pair before starting to re-extend networks

If the above steps do not resolve the issue, please open an SR with Broadcom support and reference this Article #.
