CDO mode is disabled by default in NSX. To enable CDO mode, the following prerequisites need to be satisfied:
- NSX is running on Version 6.3.0 or later
- The vSphere cluster has been prepared for NSX with VXLAN configured
- The NSX transport zone has been created
- The vSphere cluster has been added into the NSX transport zone
For the universal transport zone, CDO mode can only be enabled from the Primary NSX Manager.
