Use the display smart-link flush command to display the flush messages received on a device.
# Display the flush messages received on Device B.

Smart Link and Track collaboration configuration example
Network requirements
As shown in Figure 15:
• Device A, Device B, Device C, and Device D form maintenance domain (MD) MD_A of level 5.
Device C is a Smart Link device, and Device A, Device B, and Device D are associated devices.
Traffic of VLANs 1 through 200 on Device C is dually uplinked to Device A by Device B and Device
D.
• Configure the collaboration between Smart Link the CC function of CFD through track entries so that
traffic of VLANs 1 through 100 is uplinked to Device A by Device C through Ten-GigabitEthernet
1/0/1 (primary port of smart link group 1). Traffic of VLANs 101 through 200 is uplinked to Device
A by Device C through Ten-GigabitEthernet 1/0/2 (primary port of smart link group 2). When the
link between Device C and Device A fails, traffic is quickly switched to the secondary port of each
smart link group, and switched back to the primary ports after the fault is cleared.
