FDP cache table
Each entry in the FDP cache table contains information received from FDP or Cisco Discovery Protocol (CDP) on one interface of one device. The table is available if FDP or CDP is enabled globally. Entries appear when an FDP or CDP advertisement is received from a neighbor device. Entries are deleted when FDP or CDP is disabled on an interface or globally.
