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. The switch will
keep the information in the Management Information Base (MIB). SNMP utilities can learn the network
topology by obtaining the MIB information in each LLDP device. The LLDP function is enabled by default.
