6.7 Link Layer Discovery Protocol (LLDP)
The IEEE 802.1ab Link Layer Discovery Protocol (LLDP) is a unidirectional protocol that uses the MAC
layer to transmit specific information about the capabilities and status of the local device. The LLDP can
send as well as receive information from a remote device stored in the related MIB (or MIBs).
The LLDP does not contain a mechanism to solicit information received from other LLDP agents or to
confirm the receipt of information. However, LLDP provides the flexibility to enable a transmitter and
receiver separately, and the following LLDP agent configurations are allowed:
• only transmit information
• only receive information
• transmit and receive information
The information fields in each LLDP frame are contained in an LLDP Data Unit (LLDPDU) as a sequence
of variable length information elements. Each information element includes Type, Length, and Value fields
(TLVs).
• Type indicates the nature of information being transmitted.
• Length indicates the length of the information string in octets.
• Value is the actual information that is transmitted. (For example, a binary bit map or an alphanumeric
string that can contain one or more fields).
