The IEEE standard for LLDP (Link Layer Discovery Protocol) is IEEE 802.1AB. This standard defines the operation and frame format of LLDP, specifying how devices exchange information about their capabilities, configurations, and neighbors on a local area network. It enables network devices to discover and communicate with each other dynamically, facilitating network management, troubleshooting, and topology discovery.
LLDP is an open standard protocol standardized by the IEEE (Institute of Electrical and Electronics Engineers). It stands for Link Layer Discovery Protocol and is defined by the IEEE 802.1AB standard. LLDP allows network devices to advertise their identity, capabilities, and status to other devices on the same network segment. This helps in automated network management tasks such as inventory management, network mapping, and monitoring of network devices.
LLDP TLVs (Type-Length-Value) are elements used within LLDP frames to convey specific information about a network device’s capabilities, configuration, and identity. TLVs are structured data elements consisting of a type field that identifies the information carried, a length field specifying the size of the value field, and the value field itself containing the actual data. Examples of TLVs in LLDP include system name, port description, system capabilities, and management address TLVs. These TLVs allow devices to exchange detailed information about themselves and their connected neighbors in a standardized format, facilitating interoperability and efficient network management.
