6.2.2 SNMP Operations
The SNMP protocol includes four types of operations:
getRequest Command for retrieving specific value of an “instance”
from the managed node. The managed node responds
with a getResponse message.
getNextRequest Command for retrieving sequentially specific
management information from the managed node.
The managed node responds with a getResponse
message.
setRequest Command for manipulating the value of an “instance”
within the managed node. The managed node responds
with a getResponse message.
trap Management message carrying unsolicited
information on extraordinary events (that is, events
which occurred not in response to a management
operation) reported by the managed node.
6.2.3 The Management Information Base
The management information base (MIB) includes a collection of
managed objects. Managed objects are defined as parameters that can be
managed, such as specific information on device configuring or on
performance statistics values.
