After you upload or create a network function, you can instantiate it in your virtual infrastructure.
You can override tags when objects are not compatible with each other. For example, if you have a cloud with a CNF tag and you want to instantiate a network function catalog with the VNF tag, you can override the tag. On the Select Cloud pop-up window, expand Advanced Filters, deselect the CNF tag, and click Apply.
Note: When you override a tag, you are explicitly bypassing the system validations and verifying the success yourself.
