nsx-controller # show control-cluster logical-switches connection-table 2147483647 Host-IP Port ID 10.10.47.10 53055 50 10.10.41.11 60062 49 127.0.0.1 46279 47
Environment
VMware NSX for vSphere 6.3.x VMware NSX for vSphere 6.4.x
Cause
The Vxlan app, on startup, creates a special VNI with id 2147483647 for PTEPs. This VNI is not created by the Management Plane and is only joined by ptep hosts.
Resolution
Controller will create a special VNI (0x7FFFFFFF = 2147483647) automatically and internally and this VNI is defined out of the VNI range that user could configure on MP side. PTEP hosts will join and report its VTEP of this special ID, so that controller could replicate VTEP among joined hosts.
