I have a C3560G-48PS running c3560-ipbase-mz.122-25.SEE2.bin and I had two ports just stop working, that I know of. I connected directly to the switchport with a phone and nothing. So I just shutdown the interface and saved and then did a no shutdown on the interface and then it started working again. I also had this happen to a 4506 switch as well with POE modules. I saw no errors on the interfaces, power was good, was not at the limit of power usage and the interface was not err-disabled. Also interfaces right next to them were working fine and they worked fine the day before. Any ideas on what may cause this?
