  3. Issues and Difficulties • Switch Consistency (Type and Configuration) • Documentation (Change mgmt., ports, vlans) • Security (Physical and Virtual) • Resources • Hardware inventory • People – delegation of responsibilities (configurations, responding to outages, etc.) • Multi-departmental occupancy of buildings • New technologies • Radiation Safety Project • VoIP – exacerbated by all of the above IAC Update

Small sample and examples of concerns • Environmental controls offline due to multicast storm, After hours response by Facilities, April 2011 • Looped network takes down environmental controls requiring reconfiguration of switches and further monitoring after hours by Facilities, NOC, April 2011 • Firewall not configured to be on network and thus not firewalling, March, 2011 • Several building networks down along with environmental controls due to dual-homed server misbehaving. 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. Feb. 2011 • Network device with duplicate IP takes down a College’s central server, Feb 2011 • Emergency fiber run had to be made to bypass departmental network device incapable of handling vlans for cardkey access, Feb, 2011
