Link Layer Discovery Protocol (LLDP) simplifies network troubleshooting and enhances the ability of network management tools to discover and maintain network topologies in multi-vendor environments. LLDP defines a set of advertisement messages (TLVs), a protocol for transmitting TLVs, and a method for storing the information in received TLVs.
As a result, stations attached to a LAN can advertise information about the system and station point of attachment to other stations in the same LAN. This information can be reported to the management station through SNMP MIBs.
