Function of snmp manager
SNMP manager An SNMP manager runs a network management application. This SNMP manager is sometimes referred to as a Network Management
Server (NMS).
SNMP agent An SNMP agent is a piece of software that runs on a managed device (for example, a server, router, or switch).
Management Information Base (MIB) Information about a managed device’s resources and activity is defined by a series of objects. The structure of these management objects is defined by a managed device’s Management Information Base (MIB).
Consider the three broad categories of SNMP message types:
■ GET: An SNMP GET message retrieves information from a managed device.
■ SET: An SNMP SET message sets a variable in a managed device or triggers an action on a managed device.
■ Trap: An SNMP Trap message is an unsolicited message sent from a managed device to an SNMP manager, which can notify the SNMP manager about a significant event that occurred on the managed device.
