ManagementManagement Concept: An AgentConcept: An Agent
An AgentA functional unit
(software) that resides in a managed device
It provides management information about the managed device
It accepts instructions to configure the device
A Proxy AgentAn agent, but itdoes not reside inthe manageddevice.
