The basic question is pretty simple, and is something that every management platform has to deal with: what does the model of a device represent? Is it a desired state of a device? The device at a point in time? The known values for the device?
The problem gets more complicated if the device settings change. Which copy of the settings is the canonical copy, the one on the device or the one in GenieACS? It sounds like a device in GenieACS is a sum of all the settings of a device, not the current state of the device. That’s fine, if that’s what the author wanted. The problem with changing the GetParameterValues behavior is what happens if you just want to get a subset of values in the IGD tree? That change would wipe out everything that wasn’t in the returned values. -- Manny Veloso Sr. Solutions Engineer Smartrg.com From: Dan Morphis <[email protected]<mailto:[email protected]>> Reply-To: Community support for GenieACS users <[email protected]<mailto:[email protected]>> Date: Monday, February 2, 2015 at 2:30 PM To: Community support for GenieACS users <[email protected]<mailto:[email protected]>> Subject: Object instance state out of sync between Genie and CPE The simplest way I have to explain this is to set up the scenario. Start with a CPE with no nodes under InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection. On the CPE, add an object to WANPPPConnection. And you will get back the "1" node. Add another, and you will get the "2" node. If I then factory reset the CPE (which removes all the instances under WANPPPConnection). When I refresh the CPE from Genie, the CPE doesn't send back anything for the WANPPPConnection object. But in Genie, I still see the old "stale" instances. You can't delete the instances, because the CPE doesn't know anything about the instance and so it faults. Without the successful result from the CPE, Genie keeps the instances in its version of the device. Right now, the way I've been working around this is deleting the CPE from Genie ACS. I thought about diving into the code which handles the GetParameterValues and have it delete nodes when no values come back. But, I wanted to find out if there is something I'm missing first. -dan
