Link Layer Discovery Protocol (LLDP)
The link layer discovery 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.
This chapter describes the LLDP commands.
The starting point for using LLDP is invoking LLDP with the protocol lldp command in either
CONFIGURATION or INTERFACE mode.
The information LLDP distributes is stored by its recipients in a standard management information base
(MIB). You can access the information by a network management system through a management
protocol such as simple network management protocol (SNMP).
For details about implementing LLDP/LLDP-MED, refer to the Link Layer Discovery Protocol chapter of
the Dell PowerEdge FN I/O Aggregator Configuration Guide.
