Re: YDK augmentation problems?

preibysp1 · ‎05-06-2017

Hi, I'm trying to configure a loopback interface on XR6.1.2 device using YDK and I cannot figure out how to set the ipv4network parameters.

I'm using this config as a sample ydk-py-samples/nc-create-xr-ifmgr-cfg-30-ydk.py at master · CiscoDevNet/ydk-py-samples · GitHub. The problem is that I cannot locate the InterfaceConfiguration attribute ipv4network:

When looking through the generated python models, the Cisco_IOS_XR_ifmgr_cfg module does contain attribute ipv4network, but I still cannot use it when writing code. Could this indicate some kind of problems in module augmentation (as Cisco_IOS_XR_ifmgr_cfg is augmented by Cisco_IOS_XR_ipv4_io_cfg module for IP configuration attributes)? I have tried this with a full XR6.1.2 bundle and with a bundle including only required modules for such config, the result is the same. Or could this indicate problems with my working environment?

Thanks,

Paulius

I wonder if this is an issue with your IDE. App runs just fine for me. Have you tried another editor/IDE?

Were you able to solve your IDE integration?

Hi,

Yes I have, I even forgot about this post . It was totally my mistake as I did not include Cisco_IOS_XR_ipv4_io_cfg the first time I generated a bundle and installed it. After realising my mistake I did include this model in a bundle but did not specify the argument --upgrade when installing it, thus the cisco_ios_xr module stayed the same and I was unable to use the needed arguments.

Thanks for your help and great tutorials!!
