In theory customers can create or enhance Network Element Drivers, NEDs, since NED source (YANG, etc.) and developer guide comes with the system.
But in practice there should be no need for a customer to do so.
If a customer choses to create or enhance a NED this will mean that:
- The NED cannot be supported by Cisco TAC
- The upgrade path to official NED versions will break
The only time customer development of NEDs should be considered is:
- In case of emergency
- For one-off devices/systems
However, it is always adviced to use a qualified partner to create or enhance a NED.
