2.14 LLDP
2.14.1 LLDP
Link Layer Discovery Protocol (LLDP) is an IEEE standard OSI layer- 2 protocol. It’s used by
network devices for advertising their identity, capabilities, and neighbors’ information on a
local area network. It allows each network device, e.g. an EH7510 switch, to inform its
neighbors about its information and configurations periodically. As a result, all of the
networks devices would discover their neighbors across connected network links using this
standard mechanism.
Fig. 2.70
Fig. 2.70 allows users to have options for enabling or disabling the LLDP, as well as setting
LLDP transition parameters. This function should be enabled if users want to use Device
View to monitor the switches’ topology of the whole network. For information of using Device
View, please refer to Chapter 4 .
