questions, which is very convenient for those of us who are poor typists.
Cisco Discovery Protocol
Cisco Discovery Protocol (CDP) is used by Cisco routers and switches to ascertain basic
information about neighboring routers and switches. You can use this information to learn
addresses quickly for easier Simple Network Management Protocol (SNMP) management, as
well as learn the addresses of other devices when you do not have passwords to log in to the
other device.
