Hi,
I need some advise. I have a core switch Cisco 3850. One of the port that currently connected to my PABX having issue whereby the unknown protocol drop keeps on increasing every 2-3minutes. The rest of the port seems fine. What is the root cause of this issue? How to fix it? Can this issue give a problem to my IP phone quality like cracking sound during talking?

yes, it never under trunk mode. All this while it is under access mode.
Yes it is increasing every 1minute or 2minute.
