You can select existing tags that are available in the NSXinventory or create new tags to add to an object.
The following procedure explains the steps for adding tags to a single object. For this documentation, the segment object is considered. The steps for adding tags to other objects remain the same. You can navigate to the specific object page, and follow similar steps to add tags to that object.
For information about the maximum number of tags supported for objects in NSX, see the VMware Configuration Maximums tool at https://configmax.vmware.com/home.
