I don't think POAP handles the powering on/off the modules since we the config with the breakout included will be applied only once.
My understand is below for the POAP process
- Switch starts POAP
- It intiates DHCP IP assignment
- Then it gets the scripts file from the server
- Reloads
- applies the scheduled config (with breakout) and completes the auto provisioning.
Unless the switch goes through a 2nd reload, the breakout will not be effective.
If you happen to see it differently then please update the thread.
