本文档介绍了Smart Link配置举例。
本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解Smart Link、Monitor Link和IRF特性。
请勿将一个端口同时加入聚合组和Smart Link组，否则该端口在Smart Link组中将不会生效，也无法使用display smart-link group命令查看到。
如图1所示，某企业财务部和市场部分别使用VLAN 10和VLAN 11，出于可靠性考虑，接入设备Device A提供两条链路双上行到汇聚设备Device D。现要求如下：
· 通过配置Smart Link来实现链路备份和负载分担。财务部优先使用Device A—>Device B路径转发数据流量，市场部优先使用Device A—>Device C路径转发数据流量。
· 当Device A到Device B、Device C的两条上行链路都正常时，财务部和市场部的数据流量分别通过不同路径转发；当其中一条链路出现故障时，Smart Link功能会将故障链路上的流量快速切换到另一条链路上；当链路故障恢复时，Smart Link功能又会将数据流量及时切换回原来的转发路径。

为了实现流量在两条上行链路上的负载分担，需在Device A创建两个Smart Link组，不同Smart Link组包含相同的成员端口，但同一端口在不同Smart Link组内角色不同，且财务部和市场部使用的VLAN分别为这两个Smart Link组的保护VLAN。
为了实现链路故障恢复时，财务部和市场部的数据流量仍能切换回各自原来的路径转发，需要为两个Smart Link组都配置角色抢占模式。
为了避免当Smart Link组中的主从链路切换时，由于上游设备上的MAC地址转发表项和ARP/ND表项没有及时更新，而导致下行数据流量发生中断，需要在Device A上配置发送Flush报文功能，处于从Device A到Device D主、从链路上的端口都需要使能接收Flush报文功能。
本举例是在R2612版本上进行配置和验证的。
· 如果欲配置某端口为Smart Link组的成员端口（主端口或从端口），请先手工关闭该端口，并待Smart Link组配置完成后再开启该端口，以避免形成环路，导致广播风暴。
· 在配置Smart Link组的成员端口及其直连端口之前，请确认端口未启用STP或者RRPP功能。
· 上游设备上配置的接收处理Flush报文的控制VLAN和在Smart Link设备上配置的发送控制VLAN需要相同。
· 不同的Smart Link组需要配置不同的控制VLAN。Smart Link组的控制VLAN应同时为该Smart Link组的保护VLAN，且不要将已配置为控制VLAN的VLAN删除，否则会影响Flush报文的发送。

如图2所示，区域A和区域B分别使用VLAN 10和VLAN 11，出于可靠性考虑，接入层设备Device A和Device B都提供两条链路分别双上行到汇聚层设备Device C和Device D。现要求如下：
· Device A和Device B设备通过配置Smart Link来实现链路备份。
· 当Device A到Device C和Device D的两条上行链路都正常时，区域A的数据流量优先通过Device A—>Device C的路径转发。当该链路出现故障时，Smart Link功能会将故障链路上的流量快速切换到Device A—>Device D的链路上。当链路故障恢复时，Smart Link功能又会将数据流量及时切换回原来的转发路径。
· 当Device B到Device C和Device D的两条上行链路都正常时，区域B的数据流量优先通过Device B—>Device D的路径转发。当该链路出现故障时，Smart Link功能会将故障链路上的流量快速切换到Device B—>Device C的链路上。当链路故障恢复时，Smart Link功能又会将数据流量及时切换回原来的转发路径。
· 通过配置Smart Link和Monitor Link联动，确保Device C和Device D的上行接口出现故障时能够快速感知并将下行接口的状态变为Down，触发Smart Link进行链路切换，从而最大可能地避免区域A和区域B与外部通信中断。

为了实现Device A和Device B的链路备份，需在Device A和Device B上分别创建一个Smart Link组，区域A和区域B的VLAN分别为这两个Smart Link组的保护VLAN。
为了实现链路故障恢复时，区域A和区域B的数据流量仍能切换回各自原来的路径转发，需要为两个Smart Link组都配置角色抢占模式。
为了避免当Smart Link组中的主从链路切换时，由于上游设备上的MAC地址转发表项和ARP/ND表项没有及时更新，而导致下行数据流量发生中断，需要在Device A和Device B上配置发送Flush报文功能，Device C和Device D的下行端口都需要使能接收Flush报文功能。
本举例是在R2612版本上进行配置和验证的。
· 如果欲配置某端口为Smart Link组的成员端口（主端口或从端口），请先手工关闭该端口，并待Smart Link组配置完成后再开启该端口，以避免形成环路，导致广播风暴。
· 在配置Smart Link组的成员端口及其直连端口之前，请确认端口未启用STP或者RRPP功能。
· 上游设备上配置的接收处理Flush报文的控制VLAN和在Smart Link设备上配置的发送控制VLAN需要相同。
· 不同的Smart Link组需要配置不同的控制VLAN。Smart Link组的控制VLAN应同时为该Smart Link组的保护VLAN，且不要将已配置为控制VLAN的VLAN删除，否则会影响Flush报文的发送。
· 一个接口只能属于一个Monitor Link组。
· 请勿通过shutdown或undo shutdown命令手动开启或关闭接口来改变Monitor Link组中下行接口的状态。

如图3所示，某企业财务部和市场部分别使用VLAN 10和VLAN 11接入Device A和Device B。为了扩展性考虑，接入层设备Device A和Device B组成IRF，接入汇聚层设备Device C和Device D。现要求如下：
· 接入层设备通过配置Smart Link来实现链路备份。
· 当Device A和Device B的上行链路都正常时，财务部和市场部的数据流量通过Device A—>Device C的路径进行转发；当该链路出现故障时，Smart Link功能会将故障链路上的流量快速切换到另一条链路上；当链路故障恢复时，Smart Link功能又会将数据流量及时切换回原来的转发路径。

为了实现Device A和Device B的链路备份，需在Device A 和Device B上创建一个Smart Link组，财务部和市场部的VLAN为这个Smart Link组的保护VLAN。
为了实现链路故障恢复时，财务部和市场部的数据流量仍能切换回各自原来的路径转发，需要为两个Smart Link组都配置角色抢占模式。
为了避免当Smart Link组中的主从链路切换时，由于上游设备上的MAC地址转发表项和ARP/ND表项没有及时更新，而导致下行数据流量发生中断，需要在Device A和Device B上配置发送Flush报文功能，Device C、Device D的ten-gigabitethernet 1/0/1端口需要使能接收Flush报文功能。
本举例是在R2612版本上进行配置和验证的。
· 如果欲配置某端口为Smart Link组的成员端口（主端口或从端口），请先手工关闭该端口，并待Smart Link组配置完成后再开启该端口，以避免形成环路，导致广播风暴。
· 在配置Smart Link组的成员端口及其直连端口之前，请确认端口未启用STP或者RRPP功能。
· 上游设备上配置的接收处理Flush报文的控制VLAN和在Smart Link设备上配置的发送控制VLAN需要相同。
· Smart Link组的控制VLAN应同时为该Smart Link组的保护VLAN，且不要将已配置为控制VLAN的VLAN删除，否则会影响Flush报文的发送。
· 有关IRF的配置注意事项，请参见“虚拟化技术配置指导”中的“IRF”。
