Is port security enabled on these ports which are flapping ? can you share the configuration of one port which is shown in the logs.
Thanks,
Rajan

Hi, please share CUCM phone configuration page. From the attached switch logs we just see that phone is rebooting with no other evidence. As of now I can guest that phone is trying to upgrade its firmware but it fails and then it reboots.

Try connecting the Phones on a different switch. also check the CPU utilization on the switch if it is high or not.
Find the below bug as well for the same switch model
https://tools.cisco.com/bugsearch/bug/CSCsg96938
Let me know if that helps.
