2) Configuration on Device B
# Enable DLDP globally, configure GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 to operate in full
duplex mode, and then enable DLDP on the two ports.
[DeviceB] dldp enable
[DeviceB] interface gigabitethernet 2/0/1
[DeviceB-GigabitEthernet2/0/1] duplex full
[DeviceB-GigabitEthernet2/0/1] speed 1000
[DeviceB-GigabitEthernet2/0/1] dldp enable
[DeviceB-GigabitEthernet2/0/1] quit
[DeviceB] interface gigabitethernet 2/0/2
[DeviceB-GigabitEthernet2/0/2] duplex full
[DeviceB-GigabitEthernet2/0/2] speed 1000
[DeviceB-GigabitEthernet2/0/2] dldp enable
[DeviceB-GigabitEthernet2/0/2] quit
# Set the DLDP mode to enhanced.
[DeviceB] dldp work-mode enhance
# Set the port shutdown mode to manual.
[DeviceB] dldp unidirectional-shutdown manual
3) Verifying the configurations
After the configurations are complete, 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.
