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 the port is shut down by DLDP automatically, run the dldp reset command on the port to enable
the port to perform DLDP detection again. Alternatively, you can leave the work to DLDP, which
automatically enables the port when it detects that the link has been restored to bidirectional. For
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 or 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.
