9.1 SNMP
9.1.1 Introduction
Simple Network Management Protocol (SNMP) is designed by the Internet Engineering Task
Force (IETF) to resolve problems in managing network devices connected to the Internet.
Through SNMP, a network management system can manage all network devices that support
SNMP, including monitoring network status, modifying configurations of a network device,
and receiving network alarms. SNMP is the most widely used network management protocol
in TCP/IP networks.
Working mechanism
SNMP is separated into two parts: Agent and NMS. The Agent and NMS communicate by
SNMP packets being sent through UDP. The working system of SNMP is shown in Figure 9-1.
