3.10 Configuring LLDP

At present, the types of network devices are increasingly numerous and their configuration is

complex. In order to enable different vendors' devices to discover and interact with each other in

the network, they need a standard information exchange platform。

LLDP (Link Layer Discovery Protocol) is generated in this context, it provides a standard

link layer discovery, the local equipment can be the main ability, management address, device

identification, interface identification and other information organization (Type / Length / Value),

and encapsulated in the LLDPDU (Link Layer Discovery Protocol Data Unit) issued to the

neighbors directly connected with their neighbors to receive this information after the standard

MIB (Management Information Base) in the form of preservation for the network management

system to query and determine the link status of the communication。

This section focuses on the configuration of LLDP, including the following：

 LLDP configuration

 LLDP display

3.10.1 LLDP configuration

There are 4 types of LLDP port working modes：

TxRx: send and receive LLDP message。

Tx: send only not receive LLDP message。

Rx: only receive not send LLDP message。

Disable: neither sends nor receives LLDP messages。

When the port's LLDP operating mode changes, the port will initialize the protocol state

machine. In order to avoid the frequent change of port operation mode and cause the port to

perform initialization operation continuously, the configurable port initialization delay time is

delayed and the initialization operation is delayed when the port operation mode changes。
