If I understand correctly you want to export the list of unused protocols to a file? This is not available out of the box but should be doable through an automation script.

Some things you might need:

• Sending an SLNetMessage
• new GetInfoMessage(InfoType.Protocols)
• A list of all elements in your system and their protocol name + version
• Iterations comparing the list of protocols to the list of elements and their protocols.
• Some extra filtering (there will be some special protocols in there that are inherent to DataMiner)
• Download button interactive automation script component

Note: sending SLNetMessages is at your own risk and these messages are subject to change at any point when you upgrade your system.
