10.1 An Introduction to SNMP
Introduction
The Simple Network Management Protocol (SNMP) is a widely spread method for
managing networks. Based on a client/server concept, the SNMP server (the SNMP
manager) gets or sets the values of objects defined in a Management Information
Base (MIB) kept by the SNMP client (the SNMP agent). In addition the SNMP agent
is also able to autonomously initiate an action by sending a trap to the SNMP
manager.
This section describes the SpeedTouch™ SNMP implementation and how to use it.
SNMP in the
SpeedTouch™
SNMP has become the de-facto standard for network management. Especially the
monitoring aspect has become important: network administrators want to be
notified when things go wrong in their network. In addition, to prevent problems,
they also want to be able to do network load and trend analysis.
SNMP allows the user to access data about the SpeedTouch™ as defined in several
MIBs. This way the SpeedTouch™ can perfectly fit in a managed network,
monitored by SNMP.
Depending on the type, the SpeedTouch™ supports SNMP V1or SNMP V1, V2 and
V3 simultanseously.
