13.2 Basic SNMP Components
In general terms, an SNMP-managed network consists of a management system, agents, and managed
devices.
A network might be managed by one or several management systems. A management system such as HP
OpenView executes monitoring applications and controls managed devices. Management systems
execute most of the management processes and provide the bulk of memory resources used for network
management.
illustrates the relationship between the network manager, SNMP agent, and
the managed devices.
Figure 13-2
Example of the Primary SNMP Components
An agent (such as SNMP) residing on each managed device translates local management information
data—such as performance information or event and error information—caught in software traps, into a
readable form for the management system.
illustrates SNMP agent get-requests that
transport data to the network management software.
