I'm trying to generate a map of the physical network just from the configuration of every item in the network (switch, router). But the only way I found to be sure an Equipment is plug to another is on the interface description. If the description is badly/wrongly/not filled, I can't assert who is plugged.
The only bit i'm sure of, is on what side a
MAC address is from an
interface (from the
Mac address table).
So my question is : Is there a way to know who is on the second end of a link from my switch/router configurations ? (When I say configuration I mean
show running config for Cisco etc...)
