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.
