234As the expression shows, the TTL can be up to 65535 seconds. TTLs greater than 65535 will be roundeddown to 65535 seconds.Configuration restrictions and guidelines• To make sure that LLDP neighbors can receive LLDPDUs to update information about the currentdevice before it ages out, configure both the LLDPDU transmit interval and delay to be less than theTTL.• It is a good practice to set the LLDPDU transmit interval to be no less than four times the LLDPDUtransmit delay.• If the LLDPDU transmit delay is greater than the LLDPDU transmit interval, the device uses theLLDPDUs transmit delay as the transmit interval.Configuration procedureTo change the TTL multiplier:Step Command Remarks1. Enter system view. system-view N/A2. Set the TTL multiplier. lldp hold-multiplier value Optional.4 by default.3. Set the LLDPDU transmitinterval. lldp timer tx-interval interval Optional.30 seconds by default.4. Set the LLDPDU transmit delay. lldp timer tx-delay delay Optional.2 seconds by default.5. Set the number of LLDPDUssent each time fast LLDPDUtransmission is triggered.lldp fast-count count Optional.3 by default.Setting an encapsulation format for LLDPDUsLLDPDUs can be encapsulated in the following formats: Ethernet II or SNAP frames.• With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames andprocesses only incoming, Ethernet II encapsulated LLDPDUs.• With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames and processesonly incoming, SNAP encapsulated LLDPDUs.By default, Ethernet II frames encapsulate LLDPDUs. If the neighbor devices encapsulate LLDPDUs inSNAP frames, configure the encapsulation format for LLDPDUs as SNAP to guarantee normalcommunication with the neighbors.To set the encapsulation format for LLDPDUs to SNAP:Step Command Remarks1.
