特殊场景：H3C防火墙堆叠主备二层透明配置

场景说明：H3C F1000系列防火墙堆叠，主备使用，上下行连接交换机，交换机为锐捷交换机。流量正常通过左边链路转发，左边上下任意链路故障后，走右边链路。

思路：期初打算双活配置防火墙，在防火墙双活二层透明的配置后会对DPI功能损耗，也就是华为的统一UTM功能，AV、IPS这些功能，因此采用了主备方式，再就是由于上联是锐捷交换机，锐捷交换机不支持LACP下设置最大活动端口数的功能，因此上下联交换机不能配置聚合，锐捷采用REUP功能来实现链路主备，也就是华三这边的Smart-link功能，因此在模拟器中上下联的交换机采用Smart-Link配置。防火墙中聚合配置采用静态聚合。
