Link Layer Detection Protocol (LLDP)

Overview

Link Layer Detection Protocol (LLDP) advertises connectivity and management from the local station

to the adjacent stations on an IEEE 802 LAN. LLDP facilitates multi-vendor interoperability by using

standard management tools to discover and make available a physical topology for network

management. The Dell Networking OS implementation of LLDP is based on IEEE standard 801.1ab.

The basic LLDP commands are supported by Dell Networking OS on all Dell Networking systems, as

indicated by the characters that appear below each command heading:

• C-Series:

• E-Series: e

• S-Series: s

Commands

This chapter contains the following commands, in addition to the commands in the related section —

LLDP-MED Commands.

• advertise dot1-tlv

• advertise dot3-tlv

• advertise management

• clear lldp counters

• clear lldp neighbors

• debug lldp interface

• disable

• hello

• mode

• multiplier

• protocol lldp (Configuration)

• protocol lldp (Interface)

• show lldp neighbors

• show lldp statistics

• show running-config lldp

The starting point for using LLDP is invoking LLDP with the protocol lldp command in either the

CONFIGURATION or INTERFACE mode.
