ccna 200-301 practice question.2.3.4 UsingSNMP for network security2.3.4.1Introduction to SNMPAnother common monitoring tool is SNMPo developed to allow administrators to manage nodes, such as servers, workstations, routers, switches, and security devices in an IP network. Network administrators can use SNMP to manage network performance, identify and resolve network problems, and plan for network growth.SNMP is an application layer protocol that provides a message format for communication between managers and agents. The SNMP system consists of 3 components.The SNMP manager.SNMP agents (the nodes being managed).The Management Information Base (MIB). To configure SNMP on a networked device, the first thing to do is to define the relationship between the manager and the agent. The SNMP manager is part of the network management system (NMS). The SNMP manager requires the SNMP management software to be running. SNMPThe manager can use the "get" operation to collect information from the SNMP agent and use the "set" operation to modify the configuration on the agent. The SNMP agent and MIB reside on the networked device client. Networked devices (such as switches, routers, servers, firewalls, and workstations) must be able to be managed and equipped with the SNMP agent software module. The M1B stores data related to the operation of the device and can be accessed by authenticated remote users. The SNMP agent is responsible for accessing the device's local
