frame size config in Y1731 profile : we have <frame-size>2000</frame-size> config in y1731-profile.Even though , if we dont give this tagging , it is always pushing the packet size 2000 config to device.it is not able to unconfigure the packet size. how to delete this packet size using payload. removing the frame size tag doesnt help.attached payload. ethernet sla profile loss type cfm-synthetic-loss-measurement probe  send burst every 60 seconds packet count 60 interval 1000 milliseconds  priority 2  packet size 2000
 Hi Arun,Please provide the given ned-id's to the devices referred in the payload.--Raghavi.The devices are managed with 7.3.1 and it is CLI NED : cisco-iosxr-cli-7.33 Hi Arun,From the yangs we have default value as 1000 for type synthetic-loss and delay. so even if you remove frame-size from your payload its going to configure the default value which is 1000. Its not possible to un-configure packet size when you choose type as synthetic-loss or delay, when type is loss it wont configure the packet size.But in your case why packet size is 2000 even after frame-size is removed from the payload. Let me know the best time we can go over the issue on your setup.--Raghavi.
