Manually shutting down unidirectional links
Network requirements
As shown in Figure 10 ,
• Two switches, Device A and Device B, are connected with two fiber pairs.
• Make configuration so that DLDP, upon detecting a unidirectional link, reminds the network
administrator to manually shut down the faulty port.

Configuration procedure
1. Configure Device A:
# Enable DLDP globally.
<DeviceA> system-view
[DeviceA] dldp enable
# Configure Gigabitethernet 2/0/1 to operate in full duplex mode, configure the port rate as
1000 Mbps, and enable DLDP on the port.
[DeviceA] interface gigabitethernet 2/0/1
[DeviceA-Gigabitethernet2/0/1] duplex full
[DeviceA-Gigabitethernet2/0/1] speed 1000
[DeviceA-Gigabitethernet2/0/1] dldp enable
[DeviceA-Gigabitethernet2/0/1] quit
# Configure Gigabitethernet 2/0/2 to operate in full duplex mode, configure the port rate as
1000 Mbps, and enable DLDP on the port.
[DeviceA] interface gigabitethernet 2/0/2
[DeviceA-Gigabitethernet2/0/2] duplex full
