20.1 Simple Network Management Protocol (SNMP)
20.1.1 Background
The Simple Network Management Protocol (SNMP) is an application-layer protocol that facilitates
the exchange of management information between network devices. It is part of the Transmission
Control Protocol/Internet Protocol (TCP/IP) suite. SNMP enables network administrators to manage
network performance, find and solve network problems, and plan for network growth.
Two versions of SNMP exist: SNMP version 1 (SNMPv1) and SNMP version 2 (SNMPv2). Both
versions have a number of features in common, but SNMPv2 offers enhancements, such as
additional protocol operations. Standardization of yet another version of SNMP—SNMP version 3
(SNMPv3)—is pending. This chapter provides general descriptions of the SNMP version 1 and 2
protocol operations. Be aware that the SNMP agent running in the SmartWare is SNMP version 1
(SNMPv1) compliant.
20.1.2 SNMP Basic Components
An SNMP managed network consists of three key components: managed devices, agents, and
network-management systems (NMSs).
A managed device is a network node that contains an SNMP agent and resides on a managed
network. Managed devices collect and store management information and make this information
available to NMSs using SNMP. Managed devices, sometimes called network elements, can be
routers and access servers, switches and bridges, hubs, computer hosts, or printers.
An agent is a network-management software module that resides in a managed device. An agent has
local knowledge of management information and translates that information into a form compatible
with SNMP.
