Configuring LLDP

LLDP Overview

The Link Layer Discovery Protocol (LLDP) operates on the data link layer. With LLDP, a device can
store and maintain information about itself and the directly-connected neighbor devices for network
administrators to check link status.
LLDP Operating Mode
LLDP can operate in one of the following modes:
TxRx: A port in this mode sends and receives LLDPDUs.
Tx: A port in this mode only sends LLDPDUs.
Rx: A port in this mode only receives LLDPDUs.
Disable: A port in this mode does not send or receive LLDPDUs.
TLV Types
TLVs encapsulated in LLDPDUs fall into these categories: basic TLVs, organizationally specific TLVs,
and media endpoint discovery (MED) related TLVs.
Basic TLVs are the base of network device management. Organizationally specific TLVs are defined by
the standard organization, while MED related TLVs are vendor specific for enhanced device
management and are optional to LLDPDUs.
