Master agents

A master agent is a software program that provides the interface between an SNMP Network Manager and a subagent.

Each workstation that includes a managed component needs to have a master agent. Each managed workstation can have a different master agent. A master agent performs the following tasks:

Parses requests from the SNMP Network Manager
Routes requests from the SNMP Network Manager to the subagents
Collects and formats responses from the subagents
Returns the responses to the SNMP Network Manager
Notifies the SNMP Network Manager when a request is invalid or information is unavailable
