unable to push service policy under interface

[arynair]

I am able to push all other interface configs except the plocy ap under service-policy.please help resolve this

qos1.service_policy_qos.append(qos2)

if __name__ == "__main__":

    sp_instance = NetconfServiceProvider(address='',

                                     protocol='ssh')

    crud_service = CRUDService()

    crud_service.update(sp_instance,interface_configurations)

These lines are erroneous, because all the container and list nodes are pre-initialized in class hierarchy and must be used:

## qos under interface
QOS = interface_configuration.Qos()
qos1 =QOS.Input()
qos2 =QOS.Input.ServicePolicyQos()
qos2.service_policy_name = "TEST_POLICY"
qos1.service_policy_qos.append(qos2)

Instead you should have:

## qos under interface
qos_policy = xr_intf.InterfaceConfigurations.InterfaceConfiguration.Qos.Input.ServicePolicyQos()
qos_policy.service_policy_name = "TEST_POLICY"
interface_configuration.qos.input.service_policy_qos.append(qos_policy)

Thank you!! it worked, but the class had to be ServicePolicy, not ServicePolicyQos .

[yangorelik]

Actually both classes to use is OK, because following documentation (and YANG model) the class Input contains 2 classes ServicePolicy and ServicePolicyQos. It is up to to your application, which one (or both of them) should be used.
