Hello Leonardo,


use the following document about high cpu


http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a00804cef15.shtml#identify


K2FibAdjMan Host Mov this makes me think of mac address moves / flapping do you see any messages about mac flapping on the log ?


if so a bridging loop can be occurring


Hope to help

Giuseppe
