z 

Keep the interval for sending Advertisement packets adequate to enable unidirectional links to be 

detected in time. If the interval is too long, unidirectional links cannot be terminated in time; if the 

interval is too short, network traffic may increase in vain.  

z 

DLDP does not process any link aggregation control protocol (LACP) events. The links in an 

aggregation group are treated individually in DLDP.  

z 

When connecting two DLDP-enabled devices, make sure the DLDP software version ID fields of 

the DLDP packets exchanged between the two devices are the same. Otherwise, DLDP may 

operate improperly. 

To properly configure DLDP on the device, you need to first enable DLDP globally, and then enable it on 

each port.  

Follow these steps to enable DLDP:  

Enter system view 

— 

Enable DLDP globally  

Required 

Globally disabled by default 

Enter Ethernet 
port view 

interface interface-type 
interface-number 

Enter 
Ethernet 
port view or 
port group 
view  

Enter port 
group view 

port-group manual 
port-group-name 

Either of the two is required. 

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

Enable DLDP 

Required 

Disabled on a port by default 

 

You can enable or disable DLDP on a Layer 2 Ethernet port (an optical port or electrical port). 

 

There are two DLDP modes:  

z 

Normal mode: In this mode, DLDP does not actively detect neighbors when the corresponding 

neighbor entries age out. The system can identify only one type of unidirectional links: 

cross-connected fibers.  

z 

Enhanced mode: In this mo de, DLDP actively detects neighbors when the corresponding neighbor 

entries age out. The system can identify two types of unidirectional links: cross-connected fibers 

and disconnected fibers. 

Follow these steps to set DLDP mode:
