基于LACP配置ehterchannel
SW1
S1(config)#interface range fa0/1-2
S1(config-if-range)#channel-group 1 mode active
S1(config-if-range)#interface port-channel 1
S1(config-if)#switchport trunk encapsulation dot1q
S1(config-if)#switchport mode trunk
S1(config-if)#switchport trunk allowed vlan all
SW2
S2(config)#interface range fa0/1-2
S2(config-if-range)#channel-group 1 mode active
S2(config-if-range)#interface port-channel 1
S2(config-if)#switchport trunk encapsulation dot1q
S2(config-if)#switchport mode trunk
S2(config-if)#switchport trunk allowed vlan all
