L2 Functions > LLDP > LLDP Global Settings
LLDP (Link Layer Discovery Protocol) provides IEEE 802.1AB standards-based method for switches to
advertise themselves to neighbor devices, as well as to learn about neighbor LLDP devices. SNMP utilities
can learn the network topology by obtaining the MIB information in each LLDP device. The LLDP function is
enabled by default.
Figure 4.63 – L2 Functions > LLDP > LLDP Global Settings
LLDP: When this function is Enabled, the switch can start to transmit, receive and process the LLDP packets.
For the advertisement of LLDP packets, the switch announces the information to its neighbor through ports.
For the receiving of LLDP packets, the switch will learn the information from the LLDP packets advertised
from the neighbor in the neighbor table. Click Apply to make the change effective.
