1、二层链路聚合配置：（一对交换机间）①配置交换机a[swa]interface eth-trunk 1 //设置链路聚合1[swa-eth-trunk1]quit[swa]interface gigabitethernet 0/0/1[swa-gigabitethernet0/0/1]eth-trunk 1 //将接口0/0/1划给聚合1[swa]interface gigabitethernet 0/0/2[swa-gigabitethernet0/0/2]eth-trunk 1 //将接口0/0/2划给聚合1[swa]display interface eth-trunk 1 //查看②按照上面的命令配置交换机b
2、三层链路聚合：（一对锭缠愁颊路由器间）①配置路由器a[ra]interface eth-trunk 1 //设置链路聚合1[ra-eth-trunk1]undo portswitch //这个命令把聚合链路从二层转为三层链路[ra-eth-trunk1]ip address 192.168.1.1 24 //为eth-trunk1分配IP地址[ra-eth-trunk1]quit[ra]interface gigabitethernet 0/0/1[ra-gigabitethernet0/0/1]eth-trunk 1 //将接口0/0/1分给聚合链路1[ra]interface gigabitethernet 0/0/2[ra-gigabitethernet0/0/2]eth-trunk 2 //将接口0/0/2分给聚合链路1②配置路由器b相同的命令配置
3、一尊怠哉砑台路由器与一台交换机链路聚合：①配置路由器a[ra]interface eth-trunk 1 //设置链路聚合1[ra-eth-trunk1]undo portswitch //这个命令把聚合链路从二层转为三层链路[ra-eth-trunk1]ip address 192.168.1.1 24 //为eth-trunk1分配IP地址[ra-eth-trunk1]quit[ra]interface gigabitethernet 0/0/1[ra-gigabitethernet0/0/1]eth-trunk 1 //将接口0/0/1分给聚合链路1[ra]interface gigabitethernet 0/0/2[ra-gigabitethernet0/0/2]eth-trunk 2 //将接口0/0/2分给聚合链路1②配置交换机a[swa]interface eth-trunk 1 //设置链路聚合1[swa-eth-trunk1]quit[swa]interface gigabitethernet 0/0/1[swa-gigabitethernet0/0/1]eth-trunk 1 //将接口0/0/1划给聚合1[swa]interface gigabitethernet 0/0/2[swa-gigabitethernet0/0/2]eth-trunk 1 //将接口0/0/2划给聚合1[swa]display interface eth-trunk 1 //查看③注意路由器a的链路聚合1有IP地址，所以网内的主机要在相应的网段内
