I am running IOS 12.1(13)EA1a on a C3550-24-PWR. We have wireless access points that are connected and receiving inline power from the ports. Today, all of the access points' interfaces changed to down for no reason that I could tell as indicated by the logs. All other ports without inline power were fine. I reset the inline power ports manually with shut, no shut commands and they came back online. I have 2 questions:
1. Has anyone seen this before and is this a possible bug?
2. As a workaround, is there an interface command that I could setup to autmotically reset the ports one they are detected as going "line protocol is down"?
