user-defined port shutdown mode. To enable the port to perform DLDP detect again, you can reset the
DLDP 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 shutdown
command 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 upon
detecting that the link has been restored to bidirectional. For how to reset DLDP state with the dldp
reset command, refer to Resetting DLDP State in System View and Resetting DLDP State in Port
view/Port Group View .
The DLDP state that the port transits to upon the DLDP state reset operation depends on its physical
state. If the port is physically down, it transits to Inactive state; if the port is physically up, it transits to
Active state.
