Troubleshooting 
Symptom 
When the link state is normal, the master node  cannot receive Hello packets, and the master node 
unblocks the secondary port.

Configuring Smart Link 
Smart Link overview 
Background 
To avoid single-point failures and guarantee network reliability, downstream devices are usually 
dual-homed to upstream devices, as shown in Figure 24.

etwork 
 
 
To remove network loops on a dual-homed network, you can use a spanning tree protocol or the Rapid 
Ring Protection Protocol (RRPP). The problem with STP, however, is that STP convergence time is long, 
which makes it not suitable for users...
