The following steps can be used to manually approve an IP change in NSX UI.
Navigate to the VM’s Segment:
View Interfaces:
View Address Bindings:
Review Realized Bindings:
Move the Old IP to Ignored Bindings:
Permanently Remove the Ignored Binding:
NOTE: For NSX-T versions 3.1.X, you will need apply it from the MANAGER view instead.
Workaround:
Rely on DHCP snooping or vmtools based IP discovery. Those are enabled by default but does make assumptions on VM is getting IP from DHCP and VM has vmtools installed.
