Summary0000040: Delete object or Addobject
DescriptionHello Easycwmp team,

We are planning to incorporate EasyCwmp in one of our OpenWRT projects. So we are in the process of evaluation of EasyCwmp over other TR-069 client. We had a question about handling of instance number in EasyCwmp. If you could clarify that it would be great for our evaluation.

The question we have is related to Add and Delete Object. We wanted to know if the instance number is maintained by TR-069 client. Below is the scenario.

There are 4 instances added for a object

A.B.1.C.1.D
A.B.1.C.2.D
A.B.1.C.3.D
A.B.1.C.4.D

ACS sends a delete object on "A.B.1.C.3.D" i.e., ACS is asking CPE to delete the third instance. So now there are 3 objects left. After delete object the ACS sends a GetParameterName request on object A.B.1. What will be the CPE response for GetParameterName request from the below two response option?

A.B.1.C.1.D
A.B.1.C.2.D
A.B.1.C.4.D

or

A.B.1.C.1.D
A.B.1.C.2.D
A.B.1.C.3.D

If you need more clarification on the above question then please let us know.

According to the TR-069 standard, If the ACS send a delete object of

A.B.1.C.3.D

The CWMP should return an Invalid parameter name fault. Because the "A.B.1.C.3.D" is a parameter and not an object instance.

The right way is: The ACS should send a delete Object of "A.B.1.C.3.".

So based on the above condition, if you have 4 instances objects:

A.B.1.C.1.
A.B.1.C.2.
A.B.1.C.3.
A.B.1.C.4.

And you want to delete the "A.B.1.C.3.", you will get:

A.B.1.C.1.
A.B.1.C.2.
A.B.1.C.4.

as required by the TR-069 standard.

You can find an example for that in the lan_device script. Just add a wireless config on your openwrt and then add some wireless interface to the lan and then you can play with wireless instances

Thanks for the response. Will check with the script you have suggested.
