4.0.4.6 LLDP
Link Layer Discovery Protocol (LLDP) operates on data link layer. It stores and maintains the information about the local device
and the devices directly connected to it for network administrators to manage networks through NMS (network management
systems). In LLDP, device information is encapsulated in LLDP PDUs in the form of TLV (meaning type, length, and value)
triplets and is exchanged between directly connected devices. Information in LLDP PDUs received is restored in its MIB.
Note:
Currently the LLDP neighbor(s) can be seen through the console only. SNMP browser will be supported in the future.
LLDP Operation Mode
LLDP can operate in one of the following modes.
LLDP Mode
Description
TxRx mode
A port in this mode sends and receives LLDP PDUs
Tx mode
A port in this mode only sends LLDP PDUs
Rx mode
A port in this mode only receives LLDP PDUs
Disable mode A port in this mode does not send or receive LLDP PDUs
LLDP is initialized when an LLDP-enabled port changes to operate in another LLDP operating mode. To prevent LLDP from
being initialized too frequently, LLDP undergoes a period before being initialized on an LLDP-enabled port when the port
changes to operate in another LLDP operating mode. The period is known as initialization delay, which is determined by the
re-initialization delay timer.
