What is a Network Management System?
It is a collection of tools integrated to monitor and control the network.
It provides a single operator interface for performing most or all network management tasks.
It is usually configured to monitor critical devices and services and to initiate visual and audible alarms when it detects a problem.
What are the software components of a Network Management System (NMS) and the function each provides?
NMP => GUI, Network Map, DBMS, Event Log
NMA => Software to manage specific set of devices or services developed by network device vendors.
Describe how network maps can be used to support the activities of fault and configuration management.
Fault management helps to isolate the case of the fault configuration management; it shows physical and local configuration of the network pictorially.
Performance management shows current performance of devices and links.
Describe briefly the steps involved in seting up a network management system.
Identify the devices on the data network. You will need to discover whether each of these devices is manageable by any network management protocols.
Prioritize the mission-critical devices.
Prioritize the functional areas of network management for your organization.
Find network management applications that help perform your key areas of network management for your devices.
