I am confused by 'netconf server (Manager) and a networking device
(netconf client = Analyzer)'. This is not how NETCONF usually works: A
device runs a NETCONF server and a management application a NETCONF
client.

Anyway, the way things work with NETCONF and YANG is that you define a
YANG data model that is understood by both the NETCONF server and the
NETCONF client.

I admit that I do not know much about your specific use case but if
you make statements that sound like YANG models have to proprietary
and hence IDPEF has an advantage because it is standardized, then you
need to be able to defend that.

Hi Jürgen,

netconf will be used between a netconf server (Manager) and a networking 
device (netconf client = Analyzer). IDPEF standardize the exchanged 
content so that no additional information is needed at the Manager to 
interpret the exchanged data. With IDPEF it is not relevant which 
vendors of Analyzers and Manager are combined. How could the Manager 
interpret the configuration data of the Analyzer without any additional 
information (e.g. MIB) in the YANG environment? How could I change 
options (e.g. thresholds) of an IDS signature of any IDS vendor with 
YANG without additional information on the netconf server?

kind regards

adjustments are still needed on site of the central Manager.

This argument likely needs an explanation. There are people working
quite hard towards standardized YANG models.
