一、实验目的:建立以太通道使相同VLAN下主机互通

二、拓扑图如下

三、具体步骤如下

(1)S1三层交换机配置

Switch>enable
Switch#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname S1
S1(config)#interface port-channel 5
S1(config-if)#switchport trunk encapsulation dot1q
S1(config-if)#switchport mode trunk
S1(config-if)#exit
S1(config)#interface range f0/10-11
S1(config-if-range)#channel-group 5 mode on
S1(config-if-range)#exit
S1(config)#vlan 5
S1(config-vlan)#vlan 6
S1(config-vlan)#interface f0/1
S1(config-if)#switchport mode access
S1(config-if)#switchport access vlan 5
S1(config-if)#interface f0/2
S1(config-if)#switchport mode access
S1(config-if)#switchport access vlan 6
S1(config-if)#end
S1#copy running-config startup-config
%LINK-5-CHANGED: Interface Port-channel 5, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel 5, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/11, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/11, changed state to up

%SYS-5-CONFIG_I: Configured from console by console

Destination filename [startup-config]?
Building configuration...
[OK]

(2)S2三层交换机配置

Switch>enable
Switch#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname S2
S2(config)#interface port-channel 5
S2(config-if)#switchport trunk encapsulation dot1q
S2(config-if)#switchport mode trunk
S2(config-if)#exit
S2(config)#interface range f0/10-11
S2(config-if-range)#channel-group 5 mode on
S2(config-if-range)#exit
S2(config)#vlan 5
S2(config-vlan)#vlan 6
S2(config-vlan)#interface f0/1
S2(config-if)#switchport mode access
S2(config-if)#switchport access vlan 5
S2(config-if)#interface f0/2
S2(config-if)#switchport mode access
S2(config-if)#switchport access vlan 6
S2(config-if)#end
%LINK-5-CHANGED: Interface Port-channel 5, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel 5, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/10, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/11, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/11, changed state to up

S2#
%SYS-5-CONFIG_I: Configured from console by console

四、验证,相同VLAN下的主机是否互通

(1)vlan 5 下的PC1和PC3

(2)vlan 6 下的PC2和PC4
