The configuration file for Device B is the same as Device A. (Details not shown.) 

Example: Manually shutting down 
unidirectional links 

Network requirements 

As shown in 

Figure 3

, Device A and Device B are connected through two fiber pairs.  

Configure DLDP on the devices to meet the following requirements:  

 

Each device can detect unidirectional links caused by cross-connected fibers or a 
disconnected fiber.  

 

When a unidirectional link is detected, the administrator can manually shut down the faulty 
port based on the connection status of the link. 

 

The interface recovers from failure after the administrator clears the fault and manually brings 
up the port.

Software version used 

This configuration example was created and verified on S6300-CMW710-R2310. 

Configuration restrictions and guidelines 

When you configure DLDP, follow these restrictions and guidelines: 

 

For DLDP to operate correctly, configure the full duplex mode for the interfaces at the two ends of 
the link, and configure the same speed for the two interfaces.  

 

For DLDP to operate correctly, enable DLDP on both sides and make sure the following settings are 
consistent:  

{

 

Interval to send Advertisement packets.
