BLOCK 2 UNIT 7 NETWORK MANAGEMENT Ver IT AA-1 1

OBJECTIVES 7 a. Given equipment, perform network fault isolation techniques IAW the PC checklist 7 b. Identify principles of network management Ver IT AA-1 2

OBJECTIVE 7 a Given equipment, perform network fault isolation techniques IAW the PC checklist • Network Error Detection • Network Error Correction • Network Flow Control • Transmission Impairments Ver IT AA-1 3

Perform Network Fault Isolation Techniques Network Error Detection Network outage are: • Discovered – Best case scenario – Administrator monitors data to predict problems • Reported – Trouble reported by the user Ver IT AA-1 4

Perform Network Fault Isolation Techniques Network Error Correction Collect basic information • Ask questions – What – When – Etc. • Know what is normal for the network • Be a good listener – Maintain professionalism and military bearing Ver IT AA-1 5

Perform Network Fault Isolation Techniques Network Error Correction Check the physical site • Lights and indicators – What is normal? – Is there an alarm? • Cables and connectors – Is the cable connected? – Is it the right kind of cable? • Switches and jumpers – Is the equipment configured properly? Ver IT AA-1 6

Perform Network Fault Isolation Techniques Network Error Correction Check the network adapter • Good connection • Network adapter disabled (turned off) • Possible disconnected cable or bad cable Ver IT AA-1 7

Perform Network Fault Isolation Techniques Network Error Correction Check the IP configuration using “ipconfig/all” Ver IT AA-1 8

Perform Network Fault Isolation Techniques Network Flow Control “Ping” Command • Initiates an echo request • Testing for network connectivity • Ver IT AA-1 A successful “ping” 9

Perform Network Fault Isolation Techniques Network Flow Control “Ping” Command • A failed “ping” Ver IT AA-1 10

Perform Network Fault Isolation Techniques Network Transmission Impairments “tracert” Command • Shows the route the packet has taken, and time between segments (hops) Ver IT AA-1 11

Perform Network Fault Isolation Techniques Network Transmission Impairments • • Ver IT AA-1 Hot Spare – System or piece of equipment physically installed and preconfigured Cold Spare – Not pre-installed – Must be installed and configured 12

OBJECTIVE 7 b Identify principles of network management • Concepts • Responsibilities Ver IT AA-1 13

Principles of Network Management Concepts Network Management • Definition : ability to have a single point of control to accomplish the activities required to manage a network • Goal: to ensure network reliability and minimize network expenses Ver IT AA-1 14

Principles of Network Management Concepts When properly implemented can result in • Reduced downtime • Quick detection and correction without disruption • Ability to monitor data to anticipate problems (prediction) • Ability to log information for historical purposes • Ability to perform an action when some predefined event or situation has occurred Ver IT AA-1 15

Principles of Network Management Concepts OSI Network Management Model (FCAPS) • F ault management • C onfiguration management • A ccounting management • P erformance management • S ecurity management Ver IT AA-1 16

Principles of Network Management Responsibilities • • • Ver IT AA-1 Fault Management – Goal: detect, isolate, correct and log faults that occur Configuration management – Goal: gather/set/track configurations of all devices Accounting Management – Ability to account for resources consumed – Bandwidth, storage space, etc – Works with security management to detect and prevent fraudulent usage 17

Principles of Network Management Responsibilities • • Ver IT AA-1 Performance management – Goal: plans the future network – Gathers data to determine efficiency of the current network Security management – Goal: control access to assets – Implements firewalls, intrusion detection systems, access lists, identity management, etc 18

Summary Given equipment, perform network fault isolation techniques IAW the PC checklist • Network Error Detection • Network Error Correction • Network Flow Control • Transmission Impairments Ver IT AA-1 19

Summary Identify principles of network management • Concepts • Responsibilities Ver IT AA-1 20
