We have ex 4200 virtual chassis that had issues over the weekend with 2 of the line cards getting disabled and disconnected from the VC, supposedly in part due to a bad gbic for the fiber uplink and possibly either a storm or loop on the network. We enabled storm control and stp and we have 1 line card that has had ports being disabled one by one over the past couple days. These ports have been traced back to printers, wifi AP's and workstations. Even after clearing the errros on the ports and even disconnecting the ports from the end device, moving that device to another switch port on a different line card, the original port is not clearing. I currently have a laptop hooked up directly to one of the ports trying to diagnose. I can take this same laptop/cable and connect into a different port on a different switch and the link comes up fine. But on these ports on this particular switch, once they go down we cannot get them back up. I've include the interface details of one of the ports.
