Can you please provide full capability statement ? like you have posted partial one.

[jean-christophe-manciot]

@pgohite
It is available in another report here.

[pgohite]

Looks like device does not support "ietf-netconf-monitoring" which is required to download model from the device. You may try to upload model manually.

[jean-christophe-manciot]

@pgohite
I don't think it is possible to upload a model on NX-OSv 9k outside the list of provided mtx rpms.
It seems that the next version of NX-OS 9k does not support it either.

[pgohite]

@jean-christophe-manciot agreed, however we can load feature model in yang explorer (client) manually which are supported by device already if those models are published somewhere. Only automatic sync from device is not possible due to non availability of "ietf-netconf-monitoring".

my device supports ietf-netconf-monitoring. but still this error occurs while syncing. my device is Junos vsrx 17.3
