random-detect discard class on xr gives error : ydk.errors.YModelError: 'int' object is not iterable--->input type list of int required

[arynair]

Hi,

i am trying to configure the line "random-detect discard-class 1 10 ms 12 ms" under policy map on iosxr

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

 

#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

        policy_map_obj.policy_map_rule.append(class_map_obj)

#random detect

        random_detect_obj = class_map_obj.RandomDetect()

        random_detect_obj.threshold_min_value = 9

        random_detect_obj.threshold_min_units = "ms"

        random_detect_obj.threshold_max_value = 10

        random_detect_obj.threshold_max_units = "ms"

        random_detect_obj.discard_class = 1

#documentation says  type: list of int range: 0..7  -----> what should be the correct input?

        class_map_obj.random_detect.append(random_detect_obj)

        policy_map_obj.policy_map_rule.append(class_map_obj)

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

when eliminating the discard class line, the code works fine. "random-detect 10 ms 12 ms" gets configured

else I get the following error:

File "master.py", line 200, in QOS_config_main

please help resolve this

random_detect_obj.discard_class.append(1)
