What does LLDP stand for?

LLDP stands for Link Layer Discovery Protocol. It is a network protocol used by devices to advertise their identity, capabilities, and neighbors on a local area network. This standardized protocol enables devices to discover each other and share information, which is beneficial in managing network topology and troubleshooting connectivity issues. LLDP operates at the data link layer (Layer 2) of the OSI model, allowing devices to communicate their operational parameters and to identify the presence of other devices on the same network segment. By employing LLDP, network administrators can gain insights into the connectivity of devices and their roles within the network, enhancing visibility and efficiency in network management.
