[DeviceA] interface gigabitethernet 2/0/2 

[DeviceA-GigabitEthernet2/0/2] dldp enable 

[DeviceA-GigabitEthernet2/0/2] quit 

# Set the interval for sending Advertisement packets to 6 seconds. 

[DeviceA] dldp interval 6 

# Set the DelayDown timer to 2 seconds. 

[DeviceA] dldp delaydown-timer 2 

# Set the DLDP mode as enhanced mode. 

[DeviceA] dldp work-mode enhance 

# Set the port shutdown mode as auto mode. 

[DeviceA] dldp unidirectional-shutdown auto 

# Enable DLDP globally. 

[DeviceA] dldp enable 

2)  Configuration on Device B 

Configure Device B as you configure Device A.  

3)  Verifying the configurations 

You can use the display dldp command to display the DLDP configuration information on ports.  

# Display the DLDP configuration information on all the DLDP-enabled ports of Device A. 

[DeviceA] display dldp 

DLDP global status : enable 

 DLDP interval : 6s 

 DLDP work-mode : enhance 

 DLDP authentication-mode : none 

 DLDP unidirectional-shutdown : auto 

 DLDP delaydown-timer : 2s 

 The number of enabled ports is 2. 

 

Interface GigabitEthernet2/0/1 

 DLDP port state : disable 

 DLDP link state : down 

 The neighbor number of the port is 0. 

 

Interface GigabitEthernet2/0/2 

 DLDP port state : disable 

 DLDP link state : down 

 The neighbor number of the port is 0. 

The output information indicates that both GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 are in 

Disable state and the links are down, which means unidirectional links are detected and the two ports 

are thus shut down. 

Correct the fiber connections after detecting the problem, and perform the following operations: 

# Reset DLDP state for the ports shut down by DLDP. 

[DeviceA] dldp reset
