Configure LLDP Parameters

Configuration Condition

None

Configure Neighbor Life Time

Specify the life time of the local device information on the neighbor device by configuring the neighbor TTL so that the neighbor device can delete the local device information after the TTL of the local device arrives.

Table 7-13 Configure the neighbor life time

Configure the Delay of Sending Packets

Configuring the delay of sending packets can prevent the frequent change of the local information from causing lots of LLDPDU to be sent.

Table 7-14 Configure the delay of sending packets

Configure Packet Sending Period

The local device regularly sends the LLDP packet to the neighbor device by configuring the period of sending the packets so that the information of the local device on the neighbor device is not aged.

Table 7-15 Configure the period of sending packets

Configure Fast Sent Packet Quantity

When some LLDP configuration of the local device (for example, select the released TLV type) changes, or when the polling mechanism finds that the LLDP concerned configuration information in the local device changes after enabling the polling function, to make other devices discover the change of the local device as soon as possible, enable the fast sending mechanism, that is, continuously send the LLDPDUs of the specified quantity (it is 3 by default) at once, and then restore the normal sending period.

Table 7-16 Configure the fast sent packet quantity

Configure Re-initializing Delay

When the port work mode changes, re-initialize the port protocol status machine. To prevent the frequent change of the port work mode from re-initializing the port protocol status machine continuously, we can configure the re-initializing delay of the port.

Table 7-17 Configure the re-initializing delay

Configure LLDP Configuration Check Period

To inform the neighbor device in time after the LLDP configuration changes, we can configure the period of checking the LLDP configuration.

Table 7-18 Configure the period of checking the LLDP configuration
