1.1 Smart Link Overview
As shown in
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
Simple configuration and operation

1.1.1 Basic Concepts in Smart Link

I. 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.
