Introduction
The Simple Network Management Protocol (SNMP) is the network management protocol
of choice for the Internet and IP-based internetworks.
This chapter describes the main features of SNMP Version 1 (SNMPv1), SNMP Version 2c
(SNMPv2c) and Version 3 (SNMPv3). It also describes support for SNMP on the switch, and
how to configure the switch’s SNMP agent.
Unless a particular version of SNMP is named, “SNMP” in this chapter refers to versions
SNMPv1, SNMPv2c and SNMPv3.

Network Management Framework
A network management system has the following components:
■
One or more managed devices, each containing an agent that provides the
management functions. A managed device may be any computing device with a
network capability, for example, a host system, workstation, terminal server, printer,
router, switch, bridge, hub or repeater.
■
One or more Network Management Stations (NMS). An NMS is a host system
running a network management protocol and network management applications,
enabling the user to manage the network.
■
A network management protocol used by the NMS and agents to exchange
information.

The Internet-standard Network Management Framework is the framework used for
network management in the Internet. The framework was originally defined by the
following documents:
■
RFC 1155, Structure and identification of management information for TCP/IP based
internets (referred to as the SMI), details the mechanisms used to describe and name
the objects to be managed.
■
RFC 1213, Management Information Base for network management of TCP/ IP-based
internets: MIB-II (referred to as MIB-II), defines the core set of managed objects for the
Internet suite of protocols. The set of managed objects can be extended by adding
other MIBs specific to particular protocols, interfaces or network devices.
■
RFC 1157, A Simple Network Management Protocol (SNMP), is the protocol used for
communication between management stations and managed devices.
