Hi,
I've been trying to get Netconf-yang up and running on some 3850 switches - running XE16.6.4.
The setup instructions at https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/166/b_166_programmability_cg/configuring_yang_datamodel.html up to Configuring NETCONF-YANG step 3 work (ie.
(config)# netconf-yang
work, and after also enabling the http-server, I get all the processes going:
#show platform software yang-management process
confd : Running
nesd : Running
syncfd : Running
ncsshd : Running
dmiauthd : Running
vtyserverutild : Running
opdatamgrd : Running
nginx : Running
ndbmand : Running
pubd : Running
but after that, none of the other commands appear to work:
(config)#netconf-yang feature candidate-datastore
^
% Invalid input detected at '^' marker.
I can connect via ssh to port 830 and get a long list of capabilities, but when I try a simple rpc command, it bombs out:
$ ssh -p 830 -s user@switch netconf
user@switch's password:
<?xml version="1.0" encoding="UTF-8"?>

</rpc>
<!-- Error: bad element: /rpc (closing session) -->
$
The same occurs with many other rpc code examples in the cisco docs.
I also tried yang-explorer but it too returns little or no data from the platform. Looks like the same thing is going on under the hood there.
Is netconf-yang fully supported on this platform and IOS combination? The documents are a bit vague, but since all the processes seem to be running one would think at least some configuration and operation data would be accessible.
Or have I missed an important configuration step?
Thanks,
Daniel
