1-9z To ensure unidirectional links can be detected, make sure these settings are the same on the bothsides: DLDP state (enabled/disabled), the interval for sending Advertisement packets,authentication mode, and password.z Keep the interval for sending Advertisement packets adequate to enable unidirectional links to bedetected in time. If the interval is too long, unidirectional links cannot be terminated in time; if theinterval is too short, network traffic may increase in vain.z DLDP does not process any link aggregation control protocol (LACP) events. The links in anaggregation group are treated individually in DLDP.z When connecting two DLDP-enabled devices, make sure the DLDP software version ID fields ofthe DLDP packets exchanged between the two devices are the same. Otherwise, DLDP mayoperate improperly.Enabling DLDPFollow these steps to enable DLDP:To do… Use the command… RemarksEnter system view system-view —Enable DLDP globally dldp enable RequiredGlobally disabled by defaultEnterEthernetport viewinterface interface-typeinterface-numberEnterEthernetport viewor portgroupviewEnter portgroupviewport-group manualport-group-nameEither of the two is required.The configuration performed in Ethernet portview applies to the current port only.
