YDK : adding encapsulation dot1q 10 under interface - not getting pushed

[arynair]

please help, all other parameters except encapsulation are being pushed

ydk code:

from ydk.models.cisco_ios_xr import Cisco_IOS_XR_ifmgr_cfg as xr_intf

from ydk.models.cisco_ios_xr import Cisco_IOS_XR_l2_eth_infra_datatypes as xr_l2_eth_infra_datatypes

from ydk.types import Empty

#interface encapsulation

interface_configurations = xr_intf.InterfaceConfigurations()

interface_configuration = interface_configurations.InterfaceConfiguration()

interface_configuration.active = "act"

interface_configuration.interface_name = "GigabitEthernet0/0/0/0.200" 

interface_configuration.interface_mode_non_physical = xr_intf.InterfaceModeEnum.default

interface_configuration.description= "*****DESCRIPTION*******" #INTERFACE INPUT GIVEN HERE

interface_configurations.interface_configuration.append(interface_configuration)

primary = interface_configuration.ipv4_network.addresses.Primary()

primary.address = "192.168.200.2"

primary.netmask = "255.255.255.252"

interface_configuration.ipv4_network.addresses.primary = primary

#encapsulation under interface

encapsulation_under_int = interface_configuration.VlanSubConfiguration.VlanIdentifier()

encapsulation_under_int.vlan_type = xr_l2_eth_infra_datatypes.Vlan.vlan_type_dot1q

encapsulation_under_int.first_tag = 10

the encapsulation data is not getting added to RPC sent to device:

The vlan-identifier is a presence container; see documentation. Therefore you are missing one line:

#encapsulation under interface
encapsulation_under_int = interface_configuration.VlanSubConfiguration.VlanIdentifier()
encapsulation_under_int.vlan_type = xr_l2_eth_infra_datatypes.Vlan.vlan_type_dot1q
encapsulation_under_int.first_tag = 10
interface_configuration.vlan_sub_configuration.vlan_identifier = encapsulation_under_int

Thank you! It has been great help in understanding how to use ydk-py
