Cause
There is a coding issue related to IPv6 addresses assigned to interfaces. The code does not handle IPv6 prefix lengths correctly.
Resolution
This is a known issue currently impacting NSX-T.
Workaround
Currently there is no direct workaround, to view the interface configuration, "get interfaces" can be used.
