crud service works, but not netconfservice

fredrikjj · ‎03-23-2017

I'm working with csr1000v 16.4.1. I have this code:

from ydk.models.cisco_ios_xe.ned import Native

from ydk.services import CRUDService, NetconfService, Datastore

from ydk.providers import NetconfServiceProvider

bgp = Native().router.Bgp()

bgp.id = 100

new_neighbor = bgp.Neighbor()

new_neighbor.id = '2.2.2.2'

new_neighbor.remote_as = 65100

bgp.neighbor.append(new_neighbor)

provider = NetconfServiceProvider(address='192.168.1.127',

port=830,

username='admin',

password='admin',

protocol='ssh')

#nc = NetconfService()

#nc.edit_config(provider, Datastore.running, bgp)

crud = CRUDService()

crud.create(provider, bgp)

I have generated the APIs for the native model on IOS-XE using the guide here: Configuring Cisco IOS XE With YDK and OpenDaylight - Network-oriented programming

If I use crud, I can apply this config to the device, but if I use the netconfservice I get this error:

yangpy2) fred@ubuntu:~$ python netconftest.py

Traceback (most recent call last):

}, 'ietf-netconf', _yang_ns._namespaces['ietf-netconf']),

KeyError: 'ietf-netconf'

Please helps.

Hi,

Which version of ydk are you using? Can you try the latest ydk (0.5.4). With 0.5.4, I'm not seeing this issue with NetconfService.

fredrikjj · ‎03-24-2017

I was using 0.5.3. I've now upgraded to 0.5.4. The same script still works if I use crud, but I get a new error if I try netconf:

from ydk.models.cisco_ios_xe.ned import Native

from ydk.services import CRUDService, NetconfService, Datastore

from ydk.providers import NetconfServiceProvider

bgp = Native().router.Bgp()

bgp.id = 100

new_neighbor = bgp.Neighbor()

new_neighbor.id = '2.2.2.2'

new_neighbor.remote_as = 65100

bgp.neighbor.append(new_neighbor)

provider = NetconfServiceProvider(address='192.168.1.127',

nc = NetconfService()

nc.edit_config(provider, Datastore.running, bgp)

#crud = CRUDService()

#crud.create(provider, bgp)

Possibly some issue with how I have generated of the api via ydk-gen? Either way, considering that the XR bundle is what comes with the package, and that it doesn't really matter what OS I use (this is for educational purposes only), I will use XR instead from now on.

Glad you can get it to work with XR.

For the error, you could enable logging and try the erroneous script again. If you could then post the logs, I could debug it further.

saalvare · ‎03-27-2017

The error message comes from the XE device. Were you able to enable logging? It'd help to contrast the logs when the CRUD service and the NETCONF service is used.
