Network Management Overview

Managers and Agents

The Simple Network Management Protocol (SNMP) is a client/server standard that
helps you diagnose and monitor network health and statistics.
You can use either J-Web Quick Configuration or a configuration editor to configure
SNMP.
This chapter contains the following topics. For more information about SNMP, see
the JUNOS Network Management Configuration Guide.

A network is a complex organization of nodes and processes that must operate
reliably and efficiently. Having a single node or link failure in a network can
undermine the network's performance and result in a loss of service. Therefore,
determining where and when a network failure is occurring is a necessity.
Additionally, gathering statistics about how a network is performing can help
you diagnose the overall health of the network and pinpoint bottlenecks so
that you can address network growth appropriately.
By querying individual network nodes and receiving triggered updates, SNMP
clients are able to provide valuable feedback about the state of a network.
Because SNMP is a client/server protocol, SNMP nodes can be classified as
either clients (SNMP managers) or servers (SNMP agents).
