Monitor Link configuration example
Network requirements
As shown in Figure 28:
• Device C is a Smart Link device, and Device A, Device B, and Device D are associated devices.
Traffic of VLANs 1 through 30 on Device C is dual-uplinked to Device A through a smart link
group.
• Implement dual uplink backup on Device C. When the link between Device A and Device B (or
Device D) fails, Device C can detect the link fault and perform uplink switchover in the smart link
group.
For more information about Smart Link, see "Configuring Smart Link."
