DLDP Configuration Example

Network requirements
As shown in Figure
Switch A and Switch B are connected through two pairs of fibers. Both of them support DLDP. All
the ports involved operate in mandatory full duplex mode, with their rates all being 1,000 Mbps.
Suppose the fibers between Switch A and Switch B are cross-connected. DLDP disconnects the
unidirectional links after detecting them.
After the fibers are connected correctly, the ports shut down by DLDP are restored.

Configuration procedure
1) Configure Switch A
# Configure the ports to work in mandatory full duplex mode at a rate of 1,000 Mbps.
<SwitchA> system-view
[SwitchA] interface gigabitethernet 1/0/50
[SwitchA-GigabitEthernet1/0/50] duplex full
[SwitchA-GigabitEthernet1/0/50] speed 1000
[SwitchA-GigabitEthernet1/0/50] quit
[SwitchA] interface gigabitethernet 1/0/51
[SwitchA-GigabitEthernet1/0/51] duplex full
[SwitchA-GigabitEthernet1/0/51] speed 1000
[SwitchA-GigabitEthernet1/0/51] quit
# Enable DLDP globally.
[SwitchA] dldp enable
# Set the interval for sending DLDP packets to 15 seconds.
[SwitchA] dldp interval 15
# Configure DLDP to work in enhanced mode.
[SwitchA] dldp work-mode enhance
# Set the DLDP handling mode for unidirectional links to auto.
[SwitchA] dldp unidirectional-shutdown auto
# Display the DLDP state.
