233Configuring the management address and its encoding formatLLDP encodes management addresses in numeric or character string format in management addressTLVs.By default, management addresses are encoded in numeric format. If a neighbor encoded itsmanagement address in character string format, you must configure the encoding format of themanagement address as string on the connecting port to guarantee normal communication with theneighbor.To configure a management address to be advertised and its encoding format on a port or group ofports:Step Command Remarks1. Enter system view. system-view N/A2. Enter Ethernet interfaceview or port group view.• Enter Layer 2/Layer 3 Ethernetinterface view:interface interface-typeinterface-number• Enter port group view:port-group manualport-group-nameUse either command.3. Allow LLDP to advertisethe managementaddress in LLDPDUs andconfigure the advertisedmanagement address.lldp management-address-tlv[ ip-address ]Optional.By default, the management address issent through LLDPDUs.• For a Layer 2 Ethernet port, themanagement address is the main IPaddress of the lowest-ID VLANcarried on the port. If none of thecarried VLANs is assigned an IPaddress, no management addresswill be advertised.• For a Layer 3 Ethernet port, themanagement address is its own IPaddress. If no IP address isconfigured for the Layer 3 Ethernetport, no management address willbe advertised.4. Configure the encodingformat of themanagement address ascharacter string.lldp management-address-formatstringOptional.By default, the management address isencapsulated in the numeric format.Setting other LLDP parametersThe Time to Live TLV carried in an LLDPDU determines how long the device information carried in theLLDPDU can be saved on a recipient device.By setting the TTL multiplier, you can configure the TTL of locally sent LLDPDUs, which determines howlong information about the local device can be saved on a neighboring device. The TTL is expressed byusing the following formula:TTL = Min (65535, (TTL multiplier × LLDPDU transmit interval))
