How It all fits together

The basic communication process among the key components, SNMP, SNMP manager, SNMP Agent, MIB, and the Launcher, is as follows:

• The SNMP manager issues a request to the SNMP Agent.
• The SNMP Agent SETS and GETS information from the MIB based on the request.
• SNMP Agent sends a reply to the SNMP manager and issues a trap.

When SNMP messages are passed between the SNMP Agent and the SNMP manager, they include the MIB OID, MIB value, what the variable is set to, and the community name of the agent.
