There are many fine programs for performing various network discovery, monitoring, and analysis tasks. In this lab you will explore a basic network management application, Fluke Network Inspector 3.0 (or equivalent). You will use the Network Inspector to perform a process called network discovery. As the number of computers, servers, printers, switches, and routers on a network grows, it can be difficult to keep track of all of the relevant characteristics of the devices. Such information as MAC addresses, IP addresses, and topologies are crucial for troubleshooting a network. You will use Network Inspector to perform a network discovery on an Ethernet 10BASE-T (or 100BASE-TX) network.</p> </blockquote>⌨️ 快捷键说明
