+##### 树协议配置
+
+1. 交换机默认有生成树协议STP在工作，收敛时间很慢
+2. 作用：生成树协议的作用，防止冗余链路形成环路
+3. RSTP：快速生成树协议RSTP，收敛时间很快
+
+```C#
+spanning-tree mode rapid-pvst       //指定生成树协议的类型为RSTP
+show spanning-tree                  //査看交换机生成树运行状态
+show spanning-tree summary          //査看生成树的配置信息
+```
+
+
+
+##### 端口聚合配置
+
+```c#
+Switch(config)#int r f0/3-5
+Switch(config-if-range)#swi mode trunk             //将端口配置为Trunk模式
+Switch(config-if-range)#channel-group 1 mode on    //加入链路组1并开启
+Switch(config-if-range)#exit
+Switch(config)#port-channel load-balance dst-ip   //按目的IP地址来实现负载均衡
+Switch(config)#exit
+Switch#show etherchannel summary             //显示以太通道信息
+Switch#show interfaces etherchannel          //显示聚合端口信息
+```
