In my opinion, the Config AppKey and Network key are all can be sent in phase 1. The reasons are as follows:

updation means you would like to update the key, including network key and app key. so Config Appkey & NetKey update message has to send in phase 1, otherwise, this updation is not meaningful.
Base on the description of Config Appkey update section, as below:

The Status-Code shall be Success if the received request was redundant (add of an identical existing key, update of an identical updated key, or delete of a non-existent key), with no further action taken.

so " Config AppKey Update message can be sent in phase 1 no matter the AppKey value if it is different or not"

if Config Appkey update message exists, the configuration server can receive the appkey and netkey and then it goes to phase 1 at this moment. while configuration client will wait for the feedback from these configuration servers, all feedback can be received and then the client will consider phase 1 is over and prepare for the next phase.

So I still keep my point of veiw," Config AppKey Update message can be sent in phase 1 no matter the AppKey value if it is different or not"

anyway, I am waiting for the feedback from jackim.

Excuse me, i also have a question.

"It shall also generate an error in Phase 1 when the Config App key Update message on a valid AppKeyIndex when the AppKey value is different"

In my explanation, it means config app key message could not bring different appkey value in Phase 1?

Is it wrong? When to update the new key??

thanks for reply

Sorry about the delay.

Just to be sure that I'm not giving you wrong information, I'll talk to some colleagues about this.

Hi Joakim,

OK, sorry to make you so confused. Let me explain it more clearly.

At first, I dont understand the content mentioned on the spec, but I am a little clear after your explanation. However, what you said is different from the specification shows:

The Config AppKey Update message shall generate an error when the node is in normal operation, Phase 2 or Phase 3.
It shall also generate an error in Phase 1 when the Config App key Update message on a valid AppKeyIndex when the AppKey value is different

The Status field shall identify the Status Code for the last operation on the AppKey List.
The allowed values for Status codes and their meanings are documented in Section 4.3.5.
The Status-Code shall be Success if the received request was redundant (add of an identical existing key, update of an identical updated key, or delete of a non-existent key), with no further action taken

----as you can see above, the update of an identical updated key, the status code shall be success, while what you said is It shall also generate an error in Phase 1 when the Config App key Update message on a valid AppKeyIndex when the AppKey value is different.

so my confusion is that if there are typos for this description. in my opinion, Config AppKey Update message can be sent in phase 1 no matter the AppKey value if it is different or not. In other words,

1. your explanation if it is wrong as it is different from the spec shows.

2. my understanding if it is correct, if not. can you explain more?

thanks in advance.

Thanks, but I don't understand what it is that you are asking here.

Maybe you could elaborate a little bit on what it is that you don't understand?

Best,
Joakim

Hi Joakim,

Many thanks for your reply. Based on the information you answered, it is clear for me now. But another issue generates; why the spec shows me that New keys are distributed using the Config NetKey Update message and the Config AppKey Update message Even though the AppKey value isn't different, there shouldn't be any errors generated? in my opinion, there is not meaningful. we hope to change the AppKey by using the Config AppKey Update message.

the information above let me more confused is that probably there are some wrong explanations on the spec and the correct content should be as below:

" Config AppKey Update message can be sent in phase 1 no matter the AppKey value if it is different or not"

the following contents from spec：

The Status field shall identify the Status Code for the last operation on the AppKey List. 
The allowed values for Status codes and their meanings are documented in Section 4.3.5. 
The Status Code shall be Success if the received request was redundant (add of an identical existing key, update of an identical
updated key, or delete of a non-existent key), with no further action taken

Could you elaborate what it is you don't understand?

In the first statement:
The Config AppKey Update message shall generate an error when node is in normal operation, Phase 2 or Phase 3.
It shall also generate an error in Phase 1 when the Config Appkey Update message on a valid AppKeyIndex when the AppKey value is different.

If the AppKey value isn't different, there shouldn't be any error generated.

Best regards,
Joakim

Hi Joakim,

Joakim Jakobsen — Fri, 13 Mar 2020 12:05:51 GMT

Hi.

How I interpret the first statement:
The Config AppKey will generate an error in normal operation, or phase 2/3. OR in phase 1 when the config appkey update message on a valid AppKeyIndex when the AppKey value is different.

Best regards,
Joakim
