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

[haoywang]

Hi Experts

I'm 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

  error-message: Operation not supported (FS MGR): InPlace Modify Error:

  error-type: application

  error-tag: backend-status-summary

  error-severity: warning

  error-message: QT/SysDB backend failed, non-QT backend passed [read rest of response for details]

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>

I changed the 192.168.1.0 to 192.168.2.0 and the error occured. How can I achieve this goal？

That error is not locally generated by YDK.  It comes from the router.  If you share your YDK code snippet, I can try reproduce and follow up on the what is causing the router to reject the config.

Hi, the code related is below:

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)

I also tried to delete the PolicyManager.ClassMaps.ClassMap.Match.SourceAddressIpv4 object first and then add a new source address. The delete operation didn't raise an error but the source address is still in the config.

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)

Can you try deleting the entire match and then adding the new match with the updated src-address?

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

Cheers,

Einar

I've tried to delete the match object and a new error is raised.

Looks like I cannot delete the match object

Hi,

I tried to do same for my XR boxes and seems it works for me. Can you 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: I am running YDK 0.5.3 and the version of my XR is 6.1.2

Hi

Thanks for your response.

I tried to run your script and there is no class-map named test_CM on my XR.

I guess your class-map is match-any and mine is match-all, so the result is different.

Can you show me the config on XR?

Nope mine is also match-all because 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

class-map type traffic match-all test_CM
