For some reason NTP stopped functioning on my switches. We have a bunch of 3750s that are not syncing. I have multiple servers configured and can sync to them from my PC but not on my cisco gear. I have attached outputs of various NTP commands for review. I noticed that when I do a sh ntp associations none of the servers show as a candidate or selected only configured. I've done some research and not quite sure where to go from here.
Does anyone know why this isn't working?
