Hi Jeff,

I'm not aware of such an error-app-tag.   I'm doubtful any such support to exists as the official stance is that YANG modules are forever backwards compatible (sans deviations).

Hi Kent,

The client can receive notification and can poll the checksum to determine if the module set has changed.

I’m also trying to determine if there was acceptance with regards to returning an error app tag of “capabilities-changed” when a client sends an RPC which could potentially no longer work as expected.

Regards,
Jeff

Hi Jeff,

Both RFC 7895 and rfc7895bis (almost RFC 8407) define a checksum a client can poll, as well as a notification a client can receive, to determine when a server's module set has changed.

Hello netconf experts,

I’m trying to determine if there was closure on the topic of dynamic model changes and the impact on any connected netconf clients.

The last message appears to be 8 years ago:

Has there been any standards agreement since the above post or any other discussions ?

Kindest regards,
Jeff
