> Is CDP (Cisco Discovery Protocol) an IETF draft or RFC? No, but several years ago, we submitted a subset of CDP (which we called PDP) as an Internet-Draft to the IETF's Physical Topology MIB Working Group. It was accepted as a WG document, with a number of changes, but the WG lost interest in it more than a year ago (the Internet-Draft has since expired). The WG recently decided to go forward with just a MIB, abandoning the attempt to standardise a protocol. Keith.
