4.5 SNMP Configuration.

In a large network, a Network Management System (NMS) based on the Simple

Network Management Protocol (SNMP) is often used to keep track of operations.

SNMP, created in 1988, is the standard protocol for managing network devices. Over

TCP/IP, SNMP usually uses UDP ports 161 (SNMP) and 162 (SNMP-traps).

An SNMP implementation involves three areas of functionality: managed devices,

SNMP agents and the NMS. SNMP agents reside in network devices where they use

MIBs (information specific to the device) to interface the devices with the NMS — which

then monitors and controls devices via these agents.

SNMP manages devices via a very small command set described in Section 5.2.6.

All models are managed via SNMP. Figure 43 displays 3 panels where users can set

SNMP Configuration, Community and Trap Receivers.
