I have tried to feed myself by looking through the Admin Guide and the Provisioning Guide but things are not clear for me. I'm hoping someone can shed some light for me.
I am trying to figure out the best scheme to auto-provision a phone via TFTP (probably switching over to HTTPS later on once I iron this out). Currently, I'm testing with a SPA502G. When the phone boots, gets and IP via DHCP and contacts the TFTP server in option 66, it "resyncs" looking for the /spa502G.cfg file and gets it successfully. My Profile_Rule in that file looks like this:
<Profile_Rule ua="na">tftp://<server's IP>/SPA$MAU.cfg</Profile_Rule>
The phone reboots, "resyncs" by looking for the /SPA$MAU.cfg file via TFTP and gets it. Here's where my confusion is: What should my Profile_Rule look like in the phone's own custom config file? Should it be blank? Should it point back to the first spa502G.cfg file? Are the spa$PSN.cfg files meant to be used only on a factory-default boot? Please help set me straight :-)
Sort of off-topic, but can someone clarify the term "resync" for me? Does that mean it's only checking for changes in it's config file? Does a difference between the running config on the phone and the config file on the provisioning server trigger an immediate reboot?
Thanks in advance for anyone's help/guidance!
