Lee, I’ve seen this once recently on a WS-C3560G-48PS The issue was specific to the shared port group on the board and cleared after reboot. Other ports on the switch outside of that 12-port group were fine before reboot. I did not open a TAC case on it.
That switch was running 122-55.SE7 at the time. -J > On Aug 11, 2015, at 11:47 AM, Lee H Badman <[email protected]> wrote: > > We’re also going through TAC on this, but I’d like to see if anyone else is > seeing similar in their Cisco switching environment and might have > perspective to share. > > We have an odd, seemingly spontaneous condition where PoE stops working on a > port or two, with only switch reboot bringing it back.
