It can be used to discover and map the network connection topology and help troubleshoot the network.4.5.1 Introduction to CDP** The CDP protocol works at layer 2 (i.e., the data link layer) of the OSI seven-layer model, which means that as long as the physical and digital layers_________________________________________- LQ4data link layer are normal, the CDP works properly and has nothing to do with the higher network layers. CDP is a Cisco private protocol, which means that the protocol does not work for other non-Cisco devices.k119CDP is used by network administrators as an information gathering tool to be informed about directly connected Cisco devices. By default, Cisco devices enable the CDP protocol and periodically send CDP notices to directly connected Cisco devices, which will include the type of connected device (e.g., whether it is a router or a switch), the associated interface, and the model number of the device (e.g., whether it is an 1841 or a 7200 ) o
