LLDP
Introduction
The Link Layer Discovery Protocol (LLDP) specified in this standard allows stations
attached to an IEEE 802 LAN to advertise, to other stations attached to the same IEEE
802 LAN, the major capabilities provided by the system incorporating that station, the
management address or addresses of the entity or entities that provide management of
those capabilities, and the identification of the station’s point of attachment to the IEEE
802 LAN required by those management entity or entities.
The information distributed via this protocol is stored by its recipients in a standard
Management Information Base (MIB), making it possible for the information to be
accessed by a Network Management System (NMS) using a management protocol such
as the Simple Network Management Protocol (SNMP).
Default Settings
The LLDP on the Switch is enabled.
Tx Interval : 30 seconds.
Tx Hold : 4 times.
Time To Live : 120 seconds.
