The term switch used throughout this chapter refers to a switching device in a generic sense or the 

switching engine of a unified switch in the WX3000 series.

As shown in 

, dual-uplink networking is widely applied currently. Usually, spanning tree 

protocol (STP) is used to implement link redundancy backup in the network. However, STP is not 

suitable for users with a high demand for convergence time. Smart Link can achieve active/standby link 

redundancy backup and fast convergence to meet the user demand.  

Smart Link has the following features:

Simple configuration and operation 

A Smart Link group consists of two member ports, one master port and one slave port. Normally, only 

one port (master or slave) is active, and the other port is blocked, that is, in the standby state. When link 

failure occurs on the port in active state, the Smart Link group will block the port automatically and turn 

standby state to active state on the blocked port.
