YModelError: Could not create data node: queue-limit[1] : Schema node not found.. Path: queue-limit

[arynair]

Hi,

I am trying to configure QoS on iosxrv using the ydk-py

however, when applying queue-limit, I get an error from the system saying schema not found.

my code snippet:

#importing all required libraries here

from ydk.models.cisco_ios_xr import Cisco_IOS_XR_infra_policymgr_cfg as  xr_infra_policymgr_cfg

from ydk.services import CRUDService

from ydk.providers import NetconfServiceProvider

self.qos_config_obj = xr_infra_policymgr_cfg.PolicyManager()

#configure policy map

        policy_map_obj = self.qos_config_obj.policy_maps.PolicyMap()

        policy_map_obj.type = xr_infra_policymgr_cfg.PolicyMapType.qos

        policy_map_obj.name = policy_map1_name

        class_map_obj = policy_map_obj.PolicyMapRule()

        class_map_obj.class_name = self.pm1_class1_name

        class_map_obj.class_type = xr_infra_policymgr_cfg.PmapClassMapType.qos

        self.qos_config_obj.policy_maps.policy_map.append(policy_map_obj)

#priority level config------>WORKING

        class_map_obj.priority_level = 1

        policy_map_obj.policy_map_rule.append(class_map_obj)

        self.qos_config_obj.policy_maps.policy_map.append(policy_map_obj)

#que limit config

        que_lim_obj = class_map_obj.QueueLimit()

        que_lim_obj.value = 100

        que_lim_obj.unit = "us"

        policy_map_obj.policy_map_rule.append(que_lim_obj)

I am able to create policy map without error, but unable to push queue limit

I get following error:

please help me resolve this issue...i believe there is a mistake in the code somewhere

I am having issues with children of this class:

classPolicyManager.PolicyMaps.PolicyMap.PolicyMapRule

thanks,

i had called the api in a wrong manner..issue solved by using:

class_map_obj.queue_limit.value = 100

class_map_obj.queue_limit.unit = "us"
