2、-Trunk为静态LACP模式。将成员接口加入Eth-Trunk。配置系统优先级确定主动端。配置活动接口上限阈值。配置接口优先级确定活动链路。数据准备为完成此配置例，需准备如下的数据：两端Switch设备链路聚合组编号。SwitchA系统优先级。活动接口上限阈值。活动接口LACP优先级。操作步骤创建编号为1的Eth-Trunk，配置它的工作模式为静态LACP模式 # 配置SwitchA。 system-viewQuidway sysname SwitchASwitchA interface eth-trunk 1SwitchA-Eth-Trunk1 bpdu enableSwitchA-Eth
