We have a several Cisco 3905 phones that will not register after running a Cable Test via the Meraki MS250-48LP. The phones are powered up but not go thru the bootup process after the test. The phones can be physically un-plugged and plugged back into the same port and still will not register. We can move them to a different port on the Meraki Switch and they register. Is anyone else having a similar issue?
I am no expert with Meraki but I see this behaviour with Catalyst switches. Reboot the Meraki switch and the ports should be good. I suspect the bug is due to TDR process crashing.
