Link Layer Discovery Protocol (LLDP and LLDP-MED)
LLDP is a standardized discovery protocol defined by IEEE 802.1AB. It allows stations residing on a LAN to
advertise major capabilities, physical descriptions, and management information to other devices on the network.
A network management system (NMS) can access and display this information.
LLDP is a one-way protocol; there are no request/response sequences. Information is advertised in LLDP
Protocol Data Units (LLDPDUs) by stations implementing the LLDP transmit function, and LLDPDUs are
received and processed by stations implementing the receive function. The transmit and receive functions can
be enabled and disabled separately per port. By default, both functions are enabled on all ports.
LLDP-MED is an extension of the LLDP standard. LLDP-MED uses LLDP's organizationally-specific Type-
Length-Value (TLV) extensions and defines additional TLVs that make it easier for a VoIP deployment in a
wired or wireless LAN/MAN environment. It also makes mandatory a few optional TLVs from LLDP and
recommends not transmitting some TLVs.
LLDP Global Configuration
Use the LLDP Global Configuration page to specify global LLDP parameters and to configure the protocol on
individual ports.
To display the LLDP Global Configuration page, click LLDP > Configuration in the navigation pane.
