课程名称：SNMP Explained: Simple Network Management Protocol 概述：本课程是关于网络管理和监控系统的短期课程，重点介绍简单网络管理协议（SNMP）。课程详细讲解了SNMP的各个组成部分，包括管理信息的结构（SMI）和管理信息库（MIB）。还讨论了SNMP的操作原理及其UDP端口的使用。 SNMP通过UDP端口161/162工作，作为应用层协议，它能够监控网络、识别网络问题，并偶尔设置远程设备。SNMP的主要组件包括： 1. **SNMP管理器**：一个集中式的网络监控系统，也称为网络管理站（NMS）。它负责运行SNMP客户端应用程序。 2. **SNMP代理**：安装在受控设备上的软件管理模块，更新数据库中的数据，供管理器访问。管理器可以查看路由器保存的相关变量，例如接收到的和传输的数据包数量，以判断路由器是否拥堵。 3. **管理信息库（MIB）**：存放需要管理的资源数据，数据以层次结构排列，包含实例对象（变量）。每个代理都有不同的MIB，包含管理器负责的所有项目。MIB的八个类别包括系统、接口、地址转换、IP、UDP、ICMP和TCP。 课程还包括一次关于SNMP安装和工作原理的实践环节，最后会进行课程完成测验。
This is a short course on Network Management and Monitoring Systems. The course gives an overview of Simple Network Management Protocol (SNMP). The details of the SNMP components such as the Structure of Management Information (SMI) and Management Information Base (MIB) are discussed in detail. The principles of operation of SNMP and SNMP UDP ports are also discussed.The UDP port 161/162 is used by the application layer protocol known as SNMP, which is used to monitor networks, identify network issues, and occasionally even set up remote devices. The various components of SNMP. i) SNMP Manager - It is a network monitoring system that is centrally located. Another name for it is an NMS, or Network Management Station. An agent is a router that runs the SNMP server program; a manager is a host that runs the SNMP client application. ii) SNMP Agent - Installed on a controlled device, it is a software management module. While the agent keeps the data in the database up to date, the manager has access to the values kept there. For example, a manager can look at the pertinent variables that a router keeps, like the number of packets received and transferred, to determine whether or not the router is congested. The Management Information Base (MIB): It houses data about resources that require management. The arrangement of this data is hierarchical. It is made up of instances of objects, which are just variables. Every agent has a different MIB, which is a collection of all the items the manager is in charge of. The eight categories that comprise MIB are system, interface, address translation, IP, UDP, ICMP, and TCP. These groups reside in the MIB object.There is a hands-on practical session on the installation and working of SNMP.The course completion quiz appears at the end.
