ydk.errors.YInvalidArgumentError: Path is invalid: Cisco-IOS-XE-nativ

Hi

I am trying just to config a loop back interface by YDK in 9300 switch . I followed samples but got errors and don't know how to follow it and fix it . this my code :

from ydk.models.Cisco_IOS_XE_native import Cisco_IOS_XE_native as xe_native
from ydk.errors import YServiceProviderError
provider = NetconfServiceProvider(address='192.168.2.2',
                                    port=830,
                                    username='###',
                                    password='###',
                                    protocol='ssh')
crud = CRUDService()

native = xe_native.Native()  # create object
loopback = native.interface.Loopback()
loopback.name = 0
loopback.description = "PRIMARY ROUTER LOOPBACK"
loopback.ip.address.primary.address = "172.16.255.1"
loopback.ip.address.primary.mask = "255.255.255.255"
native.interface.loopback.append(loopback)

# read data from NETCONF device
native = crud.create(provider, native)
 # process object data
exit()

after running the code I get bellow error:

 line 68, in <module>
    native = crud.create(provider, native)

I dont have a way to test this right now, try this

from ydk.models.Cisco_IOS_XE_native import Cisco_IOS_XE_native as xe_native
from ydk.errors import YServiceProviderError

provider = NetconfServiceProvider(address='192.168.2.2',
                                    port=830,
                                    username='###',
                                    password='###',
                                    protocol='ssh')
crud = CRUDService()

native = xe_native.Native()  # create object

# Define the path to the Loopback interface configuration
loopback_path = "/native/interface/Loopback[name='0']"  # Replace '0' with your desired loopback number

# Create the Loopback object with desired configuration
loopback = xe_native.Loopback()
loopback.name = "0"  # Replace with your desired loopback number
loopback.description = "PRIMARY ROUTER LOOPBACK"
loopback.ip.address.primary.address = "172.16.255.1"
loopback.ip.address.primary.mask = "255.255.255.255"

# Update the Loopback configuration at the specified path
crud.create(provider, path=loopback_path, data=loopback)

exit()

thank you for your reply.

I tried that.

crud.create() just get two arguments so it generates error again.

@Hamed Fazel got it thanks, my mistake. Try this, this passes the native.interface to the crud.create() method instead of native. Please check this i am not able to run this locally right now.

from ydk.models.Cisco_IOS_XE_native import Cisco_IOS_XE_native as xe_native
from ydk.providers import NetconfServiceProvider
from ydk.services import CRUDService

# create a netconf provider
provider = NetconfServiceProvider(address='192.168.2.2',
                                    port=830,
                                    username='###',
                                    password='###',
                                    protocol='ssh')

# create a crud service
crud = CRUDService()

# create a native object
native = xe_native.Native()

# create a loopback interface
loopback = xe_native.Interface.Loopback()
loopback.name = 'Loopback0'  # note: name should be a string
loopback.description = "PRIMARY ROUTER LOOPBACK"

# create an ip address
ip_address = xe_native.Interface.Loopback.Ip.Address()
ip_address.primary.address = '172.16.255.1'
ip_address.primary.mask = '255.255.255.255'

# add the ip address to the loopback interface
loopback.ip.address.append(ip_address)

# add the loopback interface to the native object
native.interface.loopback.append(loopback)

# create the configuration on the device
crud.create(provider, native.interface)

# close the provider
provider.close()
