After the DLDP status of a disabled interface is reset, the interface re-detects unidirectional links. When a unidirectional link is detected, the interface enters the Disable state. The system prompts you to shut down the interface or automatically sets the interface state to DLDP Down according to the configuration. To enable the interface to detect unidirectional links again, you can reset the DLDP status of the interface as follows:
If the interface is shut down using the shutdown command, run the undo shutdown command to enable the interface to detect unidirectional links again.
If the system automatically sets the interface state to DLDP Down, wait the interface to recover using the auto recovery mechanism after the link state becomes bidirectional. You can also run the dldp reset command to reset the DLDP status of the interface.
When you reset the DLDP status globally on a device, the DLDP status is reset for all the disabled ports on the device. When you reset the DLDP status on a disabled interface, the DLDP status is reset only for this interface.
