If you have a device that is working properly but is not being shown on the Plume app, it is probable that it has a Locally Administered MAC Address (LAA).
These MAC addresses are normally assigned to a device by a network administrator, overriding the burned-in address, being useful when creating virtual machines or virtual network interfaces.
How to determine I have a device with a LAA?
You can easily recognize if your device has a LAA by looking at the 2nd character from the left in the MAC address. If the second character is one of the following, it has a LAA:
2 | 3 | 6 | 7 | a | b | e | f
examples: 4E:34:69:E0:01:25, A6:50:C1:DC:06:C1
But, why aren't these devices showing up?
We filter out the LAAs because, in the past we ran into issues where random devices would show up in the topology, to mitigate this we came up with this strategy to filter out such devices in the way mentioned above.
These kinds of devices are not being shown due to its nature of having an LAA, we are just filtering it, but that won't affect the proper functioning of the device.
