If the VLAN is notassigned a main IP address,127.0.0.1 is used.Setting Other LLDP ParametersThe TTL TLV carried in an LLDPDU determines how long the device information carried in the LLDPDUcan be saved on a recipient device.You can configure the TTL of locally sent LLDP frames to determine how long information about thelocal device can be saved on a neighbor device by setting the TTL multiplier. The TTL is expressed asfollows:TTL = Min (65535, (TTL multiplier × LLDPDU transmit interval))As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than it will be roundeddown to 65535 seconds.Follow these steps to change the TTL multiplier:To do… Use the command… RemarksEnter system view system-view —Set the TTL multiplier lldp hold-multiplier value Optional4 by default.Set the LLDPDU transmitinterval lldp timer tx-interval interval Optional30 seconds by defaultSet LLDPDU transmit delay lldp timer tx-delay delay Optional2 seconds by defaultSet the number of LLDP framessent each time fast LLDPDUtransmission is triggered.lldp fast-count count Optional3 by defaultBoth the LLDPDU transmit interval and delay must be less than the TTL to ensure that the LLDPneighbors can receive LLDP frames to update information about the device you are configuring beforeit is aged out.
