Having trouble provisioning JUST SOME Poly VVX 250 phones on 2 sites | Duplicate IPv4 address detected from
MAC: fc:44:82:c*:**:24 ( the asterisks are replacements for anonymity)
Its weird - its 2 sites with a very similar mac address that shows as a duplicate
I have already run Microsoft Software to look for a ROGUE DHCP server and it only shows one running.
I have researched what kind of device starts with MAC: fc:44 - it reveals nothing that give me any clue as to what the device is on my network - only that its intel.
I need help as to how to locate the device that is giving me the duplicate IPv4 error.
If someone can tell me what kind of device mac id: FC :44 or FC:44:82 is I would be appreciative
Another weird thing is some phones did register.
This problem is driving me bonkers.
I don't know anything about WireShark but that comes up as a tool to use in solving similar issues - can someone tell me at a high level how WireShark might help me?
