8 SNMP
8.1 Overview
The Simple Network Management Protocol (SNMP) is the most widely used network
management protocol in TCP/IP networks. SNMP enables you to remotely manage all your
network devices compliant with this protocol, such as monitoring the network status,
changing network device settings, and receiving network event alarms.
SNMP supports managing devices bought from various vendors automatically, regardless of
physical differences among the devices.
8.1.1 SNMP management framework
The SNMP management framework consists of SNMP manager, SNMP agent, and
Management Information Base (MIB).
−
SNMP manager : It is a system that controls and monitors network nodes using the
SNMP protocol. Network Management System (NMS) is the most widely used SNMP
manager in network environments. An NMS can be a dedicated network
management server, or an application that implements management functions in a
network device.
−
SNMP agent
: It is a software module in a managed device. This module is used to
manage data about the device and report the management data to an SNMP
manager.
−
MIB : It is a collection of managed objects, defining a series of attributes of managed
objects, including names, access permissions, and data types of objects. Each SNMP
agent has its own MIB. An SNMP manager can read and/or write objects in the MIB
based on the permissions assigned to the SNMP manager.
An SNMP manager manages SNMP agents in an SNMP network. The SNMP manager
exchanges management information with the SNMP agents using the SNMP protocol.
8.1.2
Basic SNMP operations
The AP supports the following basic SNMP operations:
−
Get
: An SNMP manager performs this operation to query the SNMP agent of the AP
for values of one or more objects.
