Does commands 

>Thead down           and

>Ifconfig down 

Commands are equivalent to power failure reset of node in mesh network

[Jørgen Holmefjord]

Hi,

These commands will take down the Thread and IPv6 interfaces, so for the network, it may appear similar to a power failure of the device.

Best regards,

I am using eui64 commands to comission the mesh node, if power failure occurs at a node , when the node restarts , is it necessary to commission the node again or will it connect to mesh automatically??

[Jørgen Holmefjord]

The OpenThread stack stores persistent network data automatically in flash. You should not need to recommission the device after a power failure/reboot. However, you need to make sure that the firmware does not use the default masterkey and on boot (most of our examples use autocommissioning and use default masterkey from OpenThread).

I followed this tutorial https://codelabs.developers.google.com/codelabs/openthread-hardware/#8

in which commissioning  the FTD joiner using eui64 command doesn't need to have same master key, 

I repeatedly asked the same question and received the same answer,

It would be better if someone says exactly what happens after reset , if i commission the  mesh as mentioned in above tutorial using eui64 command

The reason is due to covid , I just theoretically studied how to develop mesh using openthead cli  to interface 30 nodes, I can't implement practically to see the results (Can't access the hardware as far now) and also time to complete the project is very less,

the commands needed to commission the network as mentioned in above tutorial is shown below
