Preset : how should it work ?

[Dan Morphis]

You will have issues with the way you are doing your preconditions. For
your first preset, you want to add a precondition that it not have the tags
"READY" or "STAGE 1 OK". By deleting the tags, you also prevent the CPE
from being reconfigured if its ever factory defaulted by the customer/ACS.

Here is how I use presets to configure CPEs.

All CPEs get a base config (enable and disable services on the CPE, etc).
Then I use notification mechanism I added (
https://github.com/akcoder/genieacs) in my fork to figure out what needs to
happen with the CPE, and add tags to the CPE based on that. For example I
add the tag "Routed" or "Bridged". Then there is a preset which has tag =
"Routed" as the precondition which adds objects and sets some specific
values. Finally, I create a device specific preset which sets the WiFi SSID
and passphrase and PPPoE credentials.

In this way, if the customer ever factory defaults the CPE, the tags will
still be applied to the CPE, discrepancies will be detected by Genie after
the refresh happens (a complete refresh always happens on a 0 BOOTSTRAP
event). And in about 5 minutes the CPE will come back online. Doing things
this way has eliminated a lot of support calls from customers that are
"experts" and think factory resetting the CPE is the solution to all of
lifes problems.
