3.3.7 LLDP Function
3.3.7.1 Overview
Defined by IEEE 802.11AB, LLDP is an OSI Layer 2 Protocol that standardizes the methodology of
self-identity advertisement. It allows each networking device, e.g. a Weidmüller managed switch, to
periodically inform its neighbors about its self-information and configurations. As a result, all of the
devices would have knowledge about each other; and through SNMP, this knowledge can be
transferred to a Network Management Software for auto-topology and network visualization.
From the switch's web interface, users have the option of either enabling or disabling the LLDP, as
well as setting the LLDP transmit interval (as shown in the figure below). In addition, users are able to
view each switch's neighbor-list, which is reported by its network neighbors. Most importantly,
enabling the LLDP function allows a Network Management Software to automatically display the
network's topology as well as system setup details such as VLAN, and Trunking for the entire
network.
