1、建立etherchannel
cuterSW(config)#int range f0/1 - 2
cuterSW(config-if-range)#channel-group 1 mode auto
cuterSW(config-if-range)#
cuterSW(config-if-range)#int range f0/3 - 4

cuterSW(config-if-range)#exit
cuterSW(config)#int po1
cuterSW(config-if)#switchport trunk encapsulation dot1q
cuterSW(config-if)#switchport mode trunk
cuterSW(config-if)#
cuterSW(config-if)#int po2
cuterSW(config-if)#switchport trunk encapsulation dot1q
cuterSW(config-if)#switchport mode trunk
cuterSW(config-if)#
SU1(config)#int range f0/1 - 2
SU1(config-if-range)#channel-group 1 mode desirable
SU1(config-if-range)#int range f0/3 - 4
SU1(config-if-range)#channel-group 2 mode auto
SU1(config-if-range)#exit
SU1(config)#int po1
SU1(config-if)#switchport mode trunk
SU1(config-if)#int po2

SU2(config-if-range)#exit
SU2(config)#int po1

由此可以看出我们的etherchannel起作用了，STP也已经起来了。

3、路由和验证
pc1和pc2的配置：
pc1:192.168.1.2
255.255.255.0
192.168.1.1
pc2:192.168.2.2
255.255.255.0
192.168.2.1
PC1：
PC1 ping 网关192.168.1.1 是通的，ping PC2居然也通，看来3560上到这两个网段的路由已经建立。
PC2：
PC2 ping PC1也是通的，我们看一下3560上的路由表：
cuterSW#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.1.0/24 is directly connected, Vlan2
C 192.168.2.0/24 is directly connected, Vlan3
看来ip routing 在packet tracert 5.3的3560-24PS上默认是开启的，如果三层交换机上没有开启ip routing则要手动去开启，命令为：
cuterSW(config)#ip routing
