IIUC your question, you have various options:

1. GUI
2. SDKs
3. CLI

you need to create network in DC, attach it to cluster, attach to host NIC/s (if you want it to be
atomic operation, i.e you expect connectivity loss during the operation/s, setupnetworks should be used,
otherwise you can use attach-network dialogues in UI)
