Monitor Link configuration example
Network requirements
As shown in Figure 27, 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, and make sure that when the link between Device A and
Device B (or Device D) fails, Device C can sense the link fault and perform uplink switchover in the smart
link group.
