I have been having issues with our ZD management ip's MAC switching to the smart redundant ZD and locking us out of the web interface. To resolve this we just clear arp on the router for our management IP and this clears the issue. However this locks out client authentication for a short time before it can be realized.
Flexmaster logs shows TR-069 client registration at the exact time our management IP switches over. Can this protocol be turned off or does Flexmaster use it to communicate with the ZD's?
