交换机trunk的配置

这个实验也是有关vlan的，有２台交换机，这样的网络拓扑我的理解在一定程度上可以起到双机热备的作用．

因模拟软件无法实现VTP的功能,只能每台配置vlan

实验目的:

pc1--pc4互通

pc2--pc3互通

 

sw1:
Switch>en
Switch#conf t
Enter configuration commands, .e per line.  End with CNTL/Z.
Switch(config)#host sw1
sw1(config)#end
sw1#vlan data
sw1(vlan)#vlan 10 name vlan10
VLAN 10 added:
    Name:vlan10
sw1(vlan)#vlan 20 name vlan20
VLAN 20 added:
    Name:vlan20
sw1(vlan)#end

sw1#conf t
Enter configuration commands, .e per line.  End with CNTL/Z.
sw1(config)#int f0/1
sw1(config-if)#switchport access vlan 20
sw1(config-if)#int f0/2
sw1(config-if)#switchport access vlan 10
sw1(config)#int f0/12
sw1(config-if)#switchport mode trunk
sw1(config-if)#switchport trunk encapsulation dot1q
sw1(config-if)#end
sw1#

 

sw2:
Switch>en
Switch#conf t
Enter configuration commands, .e per line.  End with CNTL/Z.
Switch(config)#host sw2
sw2(config)#end
sw2#vlan data
sw2(vlan)#vlan 10 name vlan10
sw2(vlan)#vlan 20 name vlan20
VLAN 20 added:
    Name:vlan20
sw2(vlan)#end
sw2#sh vlan
