Practice network maps not labeled..?

[cpholgate1]

This may be an elementary question, but I have run into this a few times now and haven't found a solution.  When working through some practice labs, I have a network map of various, lets say, routers connected to together physically.

How, in the CLI, can I determine which port is connected to which other router?  I think with OSPF I found I could use the neighbors command to see where the links/ports went, but I'm sure there is some other ways that I am just missing, with or without routing protocols configured.

Thanks,

Paul

If I understood correctly, do you want to see neighbor devices and the ports which are conected into CLI without use routing protocols?

There is a protocol wich is called CDP, it is enable automatically in Cisco Devices. You can ask

show cdp neighbors

or

show cdp neighbors detail

for more information there is a Cisco release in order to understand and configure CDP.
