配置Smart Link主备链路负载分担示例组网需求如图1所示，为了保证网络的可靠性，用户侧网络采用双归属上行方式连接广域网，VLAN 100和VLAN 500报文走备份链路，其他报文走主链路。在主链路发生故障时，主链路报文能够快速切换到从链路；备份链路发生故障后，VLAN 100和VLAN 500的报文能够快速切换到主链路。并且使业务中断时间控制在毫秒级。图1 配置Smart Link主备链路冗余备份示例 配置思路采用如下的思路配置Smart Link基本功能：1. SwitchA上配置Smart Link组多实例，并将上行链路加入组中。 2. SwitchA上使能回切功能。 3. SwitchA上使能发送Flush报文功能。 4. SwitchB和SwitchC两台设备上使能Flush报文接收功能。 5. SwitchA上使能Smart Link组功能。数据准备为完成此配置示例，需准备如下的数据：SwitchA实例编号和要绑定的VLAN编号。 创建Smart Link组的ID。 SwitchA上行链路接口编号。 发送Flush报文携带的控制VLAN编号和密码。操作步骤1. 在SwitchA上配置控制VLAN，并将接口加入该VLAN中 2. system-view3.
