LLDP-Link Discovery

LLDP is an IEEE 802.1ab standard protocol. The Link Layer Discovery Protocol is used for network
discovery, and works by having the units in the network exchanging information with their
neighbors using LLDP frames.
Link discovery specifies a method and associated procedures that automatically discover
transmission links and paths between network devices.
Unlike more traditional centralized polling techniques rooted in a management plane, autonomous
link discovery procedures are rooted in and triggered by network elements composing the
transport plane. As such, autonomous link discovery procedures may be event driven and executed
in a coordinated, distributed fashion to automatically detect new link connectivity associations and
correlate link endpoint attributes between these network elements.
Once successful link correlations have been determined, autonomous notifications of these
correlated link associations are sent to management elements and/or control elements residing in
their respective management and control plane domains.
Link Layer Discovery Protocol (LLDP) is a media independent protocol allowing the LLDP agent to
learn higher-level management reach-ability and connection, and point information from
neighboring devices. Each configured device is an active LLDP agent that sends periodic messages
to all physical interfaces that listen for LLDP messages.
LLDP monitoring is implemented by collecting both LLDP neighbor information and LLDP statistics.
