Discovered hubs and other devices as part of debug process. March, 2011 • VOIP and Wireless down due to cables being moved to wrong switch ports. March, 2011 • Compromised machines swamp entire LAN affecting police/fire, March 2011 • Departmental servers down, nobody knew location of switches affecting servers nor configuration of switches thus requiring NOC to respond, find, fix, March, 2011 • Unit carrying police/fire notifications moved to wrong port on switch. After hours response by NOC, Facilities, Feb. 2011 • Lost communication on large campus network due to switches being plugged into each other incorrectly.
