思科Cisco交换机配置—— 结合以太通道的VLAN配置实验详解
Stalk
本文实例讲述了思科Cisco结合以太通道的VLAN配置实验。分享给大家供大家参考，具体如下：
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
