Smart Link Configuration 
When configuring smart link, go to these sections for information you are interested in: 
Smart Link Overview 
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:  
Active/standby backup for dual-uplink networking

Basic Concepts in Smart Link 
Smart link group 
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.

, Ethernet 1/0/1 and Ethernet 1/0/2 on Switch A are two member ports of a smart link group.  
Master port 
The master port can be either an Ethernet port or a manually-configured or static LACP aggregation 
group. For example, you can configure Ethernet 1/0/1 of switch A in 
 as the master port 
through the command line.
