Displaying and Maintaining DLDP 193Resetting DLDP State After a unidirectional link is detected, DLDP shuts down the corresponding port.To enable the port to perform DLDP detect again, you can reset DLDP state for it.A port can be in different state after you reset DLDP state for it. That is, it can be inInactive state (if the port is physically down) or in Active state (if the port isphysically up) after you reset DLDP state for it.c CAUTION:■ The configuration of resetting DLDP state performed in system view applies toall the ports shut down by DLDP.■ The configuration of resetting DLDP state performed in port view or port groupview applies to the current port or all the ports in the port group shut down byDLDP.Resetting DLDP State in System viewFollow these steps to reset DLDP in system view:Resetting DLDP State in Port view/Port Group ViewFollow these steps to reset DLDP state in port view/port group view:Displaying andMaintaining DLDPDLDP ConfigurationExampleDLDP ConfigurationExampleNetwork requirements■ Device A and Device B are connected through two fiber pairs, in which twofibers are cross-connected, as shown in Figure 52.To do… Use the command… RemarksEnter system view system-view -Reset DLDP state dldp reset RequiredTo do… Use the command… RemarksEnter system view system-view -EnterEthernetportview/portgroup viewEnterEthernetport viewinterface interface-typeinterface-numberEither is required.The configuration performed inEthernet port view applies to thecurrent port only; theconfiguration performed in portgroup view applies to all theports in the port group.Enter portgroup viewport-group { aggregationagg-id | manualport-group-name }Reset DLDP state dldp reset RequiredTo do… Use the command… RemarksDisplay the DLDP configurationof a portdisplay dldp [ interface-typeinterface-number ]Available in any viewDisplay the statistics on DLDPpackets passing through a portdisplay dldp statistics[ interface-type interface-number ]Available in any viewClear the statistics on DLDPpackets passing through a portreset dldp statistics [ interface-typeinterface-number ]Available in user view
