I knew as soon as I hit send that Id messed that up... obviously it cant use HDLC or it wouldnt work on Ethernet/tokenring/fddi etc... cdp is a media and protocol independnt protocol that runs athe data-link layer, sending periodic messages to a multicast address. yes it would use hdlc for serial lines, but not for anything else.
