The Neighbor probe collects information about a system’s neighbors. It reads Cisco Discovery Protocol (CDP) tables, Extreme Discovery Protocol (EDP) tables, Foundry Discovery Protocol (FDP) tables, and other tables to discover remote addresses on the already discovered networks, and to discover ATM information. The Neighbor Probe uses vendor-specific MIBs.
The Neighbor probe passes the remote IP addresses to the autodiscovery process, which adds the IP addresses to its list of potential discovery candidate systems. The probe does not create IP objects for the remote IP addresses.
The discovery process checks to see if any of the remote IP addresses correspond to IP objects that are already in the repository. The discovery process will use this information during the final phase of discovery to create cable, trunk cable, and network connections.
