Link Layer Discovery Protocol (LLDP)
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 operating software
implementation of LLDP is based on IEEE standard 801.1ab.
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 Networking OS Configuration Guide
