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 FTOS implementation of LLDP is based on IEEE standard 801.1ab.

The symbols

e c s z under command headings indicate which Dell Force10 platforms —

E-Series, C-Series, S-Series or Z-Series, respectively — support the command.

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.

The information distributed by LLDP is stored by its recipients in a standard Management Information

Base (MIB). The information can be accessed by a network management system through a

management protocol such as SNMP.
