Resetting DLDP state
After DLDP detects a unidirectional link on a port, the port enters Disable state. In this case, DLDP
prompts you to shut down the port manually, or it shuts down the port automatically depending on the
user-defined port shutdown mode. To enable the port to perform DLDP detect again, you can reset the
DLDP state of the port by using one of the following methods:
 If the port is shut down with the shutdown command manually, run the undo shutdown command
on the port.
 If DLDP automatically shuts down the port, run the dldp reset command on the port to enable the
port to perform DLDP detection again. Alternatively, you can wait for DLDP to automatically
enable the port when it detects that the link has been restored to bidirectional. For information
about how to reset the DLDP state by using the dldp reset command, see "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.
