Try to delete one specific interface but all are deleted with CRUD delete and Cisco_IOS_XR_ifmgr_cfg model

[icarus78]

Hi

I have successfully applied the "nc-create-xr-ifmgr-cfg-32-ydk.py" example to create a loopback interface on an XR device https://github.com/CiscoDevNet/ydk-py-samples/blob/master/samples/basic/crud/models/cisco-ios-xr/Cisco-IOS-XR-ifmgr-cfg/nc-create-xr-ifmgr-cfg-32-ydk.py

Now, I want to remove that specific loopback interface, but when using the same model with the "crud.delete" operation, all interfaces on the devices are deleted, although the XML output shows that only Loopback200 is on the RPC message sent to the device.

What I am missing here to delete only the specific loopback interface?.

Thanks

Configuration commited on the device via NETCONF

Your Script

from ydk.services import CRUDService from ydk.providers import NetconfServiceProvider from ydk.models.cisco_ios_xr import Cisco_IOS_XR_ifmgr_cfg \ as xr_ifmgr_cfg

provider = NetconfServiceProvider( ... ) crud = CRUDService()

interface_configurations = xr_ifmgr_cfg.InterfaceConfigurations() # create object

interface_configuration = interface_configurations.InterfaceConfiguration() interface_configuration.active = "act" interface_configuration.interface_name = "Loopback200" interface_configurations.interface_configuration.append(interface_configuration) crud.delete(provider, interface_configurations)

RPCs are not visible in the description. Could you please correct the description or/and attach full log file

[icarus78]

Hi ygorelik

I´m not sure why it is not visible, although I can see them when editing the comment.

I´m attaching a screen shot with the RPC outputs.

Thanks

Here you can see that delete operation is set on the container interface-configurations. Hence it was applied to all the interfaces. The YDK-0.8.5 documentation explicitly gives you an example on how to delete list element. Please follow the recommendations.

This is not a bug. Could you please close the issue and move the discussion to Cisco Community.

Hi ygorelik

Thanks for your feedback. I manage to make the script work by following your recommendation and link provided. I´ll proceed to close the discussion
