22、.1218.0002 129.65 五：总结与原理分析以太通道有两种配置方式，第一种是手动配置：mode on；第二种是协议配置模式，而协议配置模式有两种：LACP（链路汇聚控制协议/公有协议），其链路状态有四种，on（强制不适用协议，开启）、off（防止端口开启）、active（使得端口使用LACP协议开启）、passive（使得端口进入被动协商状态，被叫才开启，默认使用）；PAGP（端口汇聚协议/思科私有）：on （同上） off （同上） desirable（同active）auto （同passive）。六：配置show runSW3：!version 12.3service time
