1-12user-defined port shutdown mode. To enable the port to perform DLDP detect again, you can reset theDLDP state of the port in one of the following methods:z If the port is shut down with the shutdown command manually, use the undo shutdowncommand on the port.z If the port is shut down by DLDP automatically, use the dldp reset command on the port.Alternatively, you can leave the work to DLDP, which can enable the port automatically upondetecting that the link has been restored to bidirectional. For how to reset DLDP state with the dldpreset command, refer to Resetting DLDP State in System View and Resetting DLDP State in Portview/Port Group View.The DLDP state that the port transits to upon the DLDP state reset operation depends on its physicalstate. If the port is physically down, it transits to Inactive state; if the port is physically up, it transits toActive state.Resetting DLDP State in System ViewResetting DLDP state in system view applies to all the ports shut down by DLDP.Follow these steps to reset DLDP in system view:To do… Use the command… RemarksEnter system view system-view —Reset DLDP state dldp reset RequiredResetting DLDP State in Port view/Port Group ViewResetting DLDP state in port view or port group view applies to the current port or all the ports in the portgroup shut down by DLDP.Follow these steps to reset DLDP state in port view/port group view:To do… Use the command… RemarksEnter system view system-view —EnterEthernetport viewinterface interface-typeinterface-numberEnterEthernetportview/portgroup view Enter portgroup viewport-group manualport-group-nameEither is required.The configuration performed inEthernet port view applies to thecurrent port only; the configurationperformed in port group view appliesto all the ports in the port group.Reset DLDP state dldp reset RequiredDisplaying and Maintaining DLDPTo do… Use the command… RemarksDisplay the DLDPconfiguration of a portdisplay dldp [ interface-typeinterface-number ] Available in any viewDisplay the statistics onDLDP packets passingthrough a portdisplay dldp statistics [ interface-typeinterface-number ] Available in any view
