To enable DLDP to operate properly, make sure the DLDP authentication modes and the passwords of 

the both sides of a link are the same.  

 

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 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 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 

 and 

.  

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. 

Resetting DLDP state in system view applies to all the ports shut down by DLDP. 

Follow these steps to reset DLDP in system view: 

Enter system view 

system-view 

—

Resetting DLDP state in port view or port group view applies to the current port or all the ports in the port 

group shut down by DLDP. 

Follow these steps to reset DLDP state in port view/port group view: 

Enter system view 

system-view 

— 

Enter Ethernet 
port view 

interface interface-type 
interface-number 

Enter 
Ethernet port 
view/port 
group view 

Enter port 
group view 

port-group manual 
port-group-name 

Either is required. 

Configurations made in Ethernet 
port view apply to the current port 
only; configurations performed in 
port group view apply to all the ports 
in the port group.
