In this video, Todd Lammle shows you some great troubleshooting tools by using Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP), a nonproprietary version of CDP. In addition to learning how to use these great tools, Todd also shows you how to create a local hosts table as well as how to verify the hostnames by using ping and telnet.
- [Narrator] So let's run back out to our…favorite router, the Corp router.…And let's go ahead and do something…called Cisco Discovery Protocol,…Link Layer Discovery Protocol and then set our host names.…So let me log in here and Cisco Discovery Protocol…starts with Cisco so I think it…would tell you Cisco Propitiatory.…I can get information about my neighbors.…I can get their host name which is the device ID.…The local interface, that's my interface…who I connect to them with.…The capability router switch and then on,…the platform, what type of Cisco device they are, 28113560.…
And then the port Id which is the interface I'm…connected to our this Corp router is…connected to on the remote device.…Now these are only directly connected devices.…Now the other command I can use show cdp neighbor detail.…And you can type out the whole thing…but show cdp neighbor detail or show cdp entry asterisk.…Either one is going to give me the same information…as show cdp neighbor plus the IP address of…my neighbor and their IOS version.…
