LLDP-compatible stations can consist of anyinterconnection device including PCs, IP Phones, switches, and routers. EachLLDP station stores LLDP information in a standard Management InformationBase (MIB), making it possible for the information to be accessed by a networkmanagement system (NMS) or application.Each LLDP station:• advertises connectivity and management information about the local station toadjacent stations on the same 802 LAN (802.3 Ethernet with EthernetSwitches 325 and 425).
