這個實驗也是有關vlan的，有２臺交換機，這樣的網路拓撲我的理解在一定程度上可以起到雙機熱備的作用． 因模擬軟體無法實現VTP的功能,只能每臺配置vlan 實驗目的: 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
