Operation not supported (FS MGR): InPlace Modify Error:

Trying to update the source match address in a class-map and YDK returned an error: 

YPYServiceProviderError: Server reported an error while committing change.

  error-type: application

  error-tag: operation-failed

  error-severity: error

  error-path: ns1:policy-manager/ns1:class-maps/ns1:class-map[type = 'traffic' and name = 'flow1_cm']/ns1:name

The original XML config is:

<class-maps>

    <class-map>

      <type>traffic</type>

      <name>flow1_cm</name>

      <class-map-mode-match-all/>

      <match>

        <source-address-ipv4>

          <address>192.168.1.0</address>

          <netmask>255.255.255.0</netmask>

        </source-address-ipv4>

        <destination-address-ipv4>

          <address>192.168.100.0</address>

          <netmask>255.255.255.0</netmask>

        </destination-address-ipv4>

      </match>

    </class-map> 

 changed the 192.168.1.0 to 192.168.2.0 and the error occured. 

def update_flow():

    policy_manager = PolicyManager()

    class_maps = policy_manager.class_maps 

    cm = class_maps.ClassMap()

    cm.name = 'flow1_cm'

    cm.type = ClassMapTypeEnum.traffic

    cm.class_map_mode_match_all = Empty()

    source = cm.match.SourceAddressIpv4()

    source.address = '192.168.2.0'

    source.netmask = '255.255.255.0'

    cm.match.source_address_ipv4.append(source)

    dest = cm.match.DestinationAddressIpv4()

    dest.address = '192.168.100.0'

    dest.netmask = '255.255.255.0'

    cm.match.destination_address_ipv4.append(dest) 

    class_maps.class_map.append(cm) 

    provider = get_connection() 

    update(provider, policy_manager)

    release_connection(provider)

The code is:

def delete_test():

  provider = get_connection()

  p_object = PolicyManager()

  p_result = read(provider, p_object)

   for j in p_result.class_maps.class_map:

   for k in j.match.source_address_ipv4:

   print k.address

  delete(provider, k) 

  release_connection(provider)

Try deleting the entire match and then adding the new match with the updated src-address. 

 The problem you may be hitting is that the source address isn't independently updatable.

Tried to delete the match object and a new error is raised.

 Looks like cannot delete the match object 

Tried to do same for my XR boxes and seems it works for me. Try to copy paste the code (in attachment) if it runs also for you.

• The prints just iterate through the class map and print its name, type and source/dest ip addresses/masks
• The edit_class_map function do the trick with addying IPs to class_map

EDIT:  running YDK 0.5.3 and the version of my XR is 6.1.2

Since you cannot specify match-any for match-source address or destination address. Error message from ASR if you want to configure it like that:

!!% Policy manager does not support this feature: Match all is the only mode supported for match type "source-address-ipv4" in class-map type "traffic"

end 

Class map test_CM is my class map I am editing. So use your name in that code. Hopefully it will work. Here is mine config from XR:

RP/0/0/CPU0:TFI-LAB-XRv6.1.2-01#show run class-map
