10 Discovery
LLDP (Link Layer Discovery Protocol) is defined in IEEE 802.1ab. It is a standard L2
discovery method which integrates the info such as management addresses, device and
interface identifications of local network devices and transmits to the neighbor devices. After
receiving the info, they will save it in form of standard MIB (Management Information Base)
for NMS query and link communication judgment.
It can also integrate the info and transmit to its own remote devices. The info
received by the local network device will be kept in the form of MIB. The following shows
how it works.
Block diagram of LLDP principles
LLDP is realized based on:
● LLDP module updates its local system MIB, as well as the customized extension
MIB, through the interaction between LLDP agent and MIBs of physical topology, entity,
interface and other types.
● Encapsulate the info of local network device into LLDP frames and transmit to the
remote device.
● Receive the LLDP frame sent by the remote device to update LLDP remote system
MIB and customized extension MIB.
● Master the info of remote device such as connection interface and MAC address
through the transmitting & receiving function of LLDP agent.
● The local system MIB stores local device info, including device and interface IDs,
system name and description, interface description, network management address, etc.
● The remote system MIB stores local device info, including device and interface IDs,
system name and description, interface description, network management address, etc.
Based on LLDP, LLDP-MED allows other units to expand. The info checked by network
devices facilitates fault analysis and deepens the accurate understanding of network
topology by management system.
