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.

Agent Gathering Data from a MIB and Sending Traps to the Manager
The SNMP agent captures data from management information bases, or MIBs, which are device
parameter and network data repositories, or from error or change traps.
A managed element—such as a router, access server, switch, bridge, hub, computer host, or network
element (such as an ONS 15600)—is accessed through the SNMP agent. Managed devices collect and
store management information, making it available through SNMP to other management systems having
the same protocol compatibility.
