Smart Link Overview
As shown in Figure
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

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.

In Figure 1-1, GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 on Switch A are two member ports of a
smart link group.
