The haneWIN LLDP software implements a LLDP Agent based on the IEEE 802.1AB standard for the Link Layer Discovery Protocol. The Link Layer Discovery Protocol (LLDP) is a protocol for discovering the physical topology in 802 LANs. Adjacent stations are discovered and stored by the LLDP agent for retrieval by a SNMP based network management system. Starting with version 1.3 the software can optionally read and send CDP (Cisco Discovery Protocol) packets. Information received in CDP packets is added to the LLDP MIB database of the agent.
