9 SNMP
9.1 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.
9.1.1 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.
9.1.2 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.
− Set: An SNMP manager performs this operation to set values of one or more objects in the MIB of
the SNMP agent of the AP.
