If your workflows fail or the NSX Edges are unstable, you can perform troubleshooting steps.
When you change the distributed port group configuration on the vSphere Client, workflows might fail and the NSX Edges might become unstable.
Removal or modification of the distributed port groups for overlay and uplink that were created during the NSX Edge cluster setup of cluster configuration, is not allowed by design.
If you require to change the VLAN or IP Pool configuration of NSX Edges, you must first remove elements of NSX-T Data Center and the vSphere with Kubernetes configuration from the cluster.
For information about removing elements of NSX-T Data Center, see the NSX-T Data Center Installation Guide.
