步骤一：

确认S12700设备正常添加一级AS设备，在一级AS设备上正确配置了其下行连接二级AS设备的Fabric-port。并配置接入AS认证设备白名单。

步骤二：

确认接入AS设备S5720版本与Parent节点S12700版本一致(均为V200R008C00SPC500版本)，二级AS设备S5720为空配置启动。

步骤三：

登录一级AS设备查询设备查看Fabric-port的状态信息。

信息显示表示一级AS连接Parent节点Fabric-port接口UP，Connected状态。但与下游二级AS设备接口显示Down，原因为AS使用不支持端口连接Parent节点。确认二级AS设备S5720采用下行端口GE0/0/1和GE0/0/2与上游AS设备GE0/0/23和GE0/0/24互连，未使用上行插卡接口与上游一级AS互连。

在二级AS设备上使用上行插卡接口与一级AS设备下行接口互连解决。
