142Step Command Remarks3. Set the LLDPDU transmitinterval. lldp timer tx-interval interval Optional.The default setting is 30 seconds.4. Set LLDPDU transmit delay. lldp timer tx-delay delay Optional.The default setting is 2 seconds.5. Set the number of LLDPDUssent each time fast LLDPDUtransmission is triggered.lldp fast-count count Optional.The default setting is 3.NOTE:• The TTL can be up to 65535 seconds. Longer TTLs will be rounded off to 65535 seconds.• Both the LLDPDU transmit interval and delay must be smaller than the TTL to make sure that the LLDPneighbors can receive LLDPDUs to update information about the router you are configuring before it isaged out.• H3C recommends that you set the LLDPDU transmit interval to be no smaller than four times the LLDPDUtransmit delay.• If the LLDPDU transmit delay is greater than the LLDPDU transmit interval, the router uses the LLDPDUstransmit delay as the transmit interval.Configuring the encapsulation format for LLDPDUsLLDPDUs can be encapsulated in Ethernet II or SNAP frames.• With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames andprocesses an incoming LLDP frame only when it is Ethernet II encapsulated.• With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames and processesan incoming LLDP frame only when it is SNAP encapsulated.By default, LLDPDUs are encapsulated in Ethernet II frames. If the neighbor routers encapsulate LLDPDUsin SNAP frames, configure the encapsulation format for LLDPDUs as SNAP to guarantee normalcommunication with the neighbors.To configure the encapsulation format for LLDPDUs:Step Command Remarks1. Enter system view. system-view N/A2. Enter Ethernet interface viewor port group view.• Enter Layer 2 or Layer 3 Ethernetinterface view:interface interface-typeinterface-number• Enter port group view:port-group manual port-group-nameUse either command.3. Configure the encapsulationformat for LLDPDUs as SNAP. lldp encapsulation snap Ethernet II encapsulationformat applies by default.
