200-301 ccna exam dump.2. step 1: Determine the network diagram using CDP The Cisco Discovery Protocol (CDP) is useful not only for examining network diagram information, but also for refining other necessary information about the devices and topology involved. In reality, the network diagram may be old and outdated, possibly because the cables have been removed and the network56 Chapter 3 Troubleshooting LAN Switchingnetwork diagram is not up to date. I suspect that Cisco will purposefully create test questions for such issues by including inaccurate information in the diagram. However, it is likely that the exam will include a network diagram that does not have all the necessary information listed in the diagram, and it will be necessary to use the CDP to find additional details. Therefore, this subsection reviews the contents of the CDP and the first steps of troubleshooting the LAN data platform, as described below.Step 1 Verify the accuracy of the network diagram using the CDP and complete the information listed in the network diagram.Tip: The methods for troubleshooting LAN switching are numbered in this chapter and Step 1 begins here. The steps and numbering are not important for the exam; the reason for numbering these steps in this chapter is to make them easy to find and reference. * "" '' 'Cisco routers, switches, and other devices use CDP for a variety of reasons; routers and switches use CDP to inform neighboring devices of basic information about themselves, such as host name, device type, IOS version, and interface number. Three of these special commands list the CDP information learned from neighboring devices, as shown in Table 3-1. In fact, even without a network diagram, an administrator can draw a network diagram consisting of routers and switches based on the output of the showcdp command.Table 3-1 showcdp Commands to Display Adjacent Device Informationshow cdp neighbors [type number] Displays summary information for each neighboring device in a row, and if a specific interface is specified, only the neighboring device information connected to that interface is displayedshow cdp neighbors detail Displays a set of detailed information (about 15 lines), each set corresponds to one neighboring deviceshow cdp entry name Displays the same information as the showcdpneighborsdetail command, but only displays the neighboring devices specified by the name parameter
