一：创建VLAN１０ ２０ ３０ ４０ １００ ２００ 并将PC机加入不同的vLan。[sw1]vlan batch 10 20 30 40 100 200[sw1]int g0/0/1 [sw1-GigabitEthernet0/0/1]port link-type access [sw1-GigabitEthernet0/0/1]port default vlan 10[sw1-GigabitEthernet0/0/1]int g0/0/2[sw1-GigabitEthernet0/0/2]port link-type access[sw1-GigabitEthernet0/0/2]port default vlan 20[sw1-GigabitEthernet0/0/2]int g0/0/3[sw1-GigabitEthernet0/0/3]port link-type access[sw1-GigabitEthernet0/0/3]port default vlan 30[sw1-GigabitEthernet0/0/3]int g0/0/4[sw1-GigabitEthernet0/0/4]port link-type access[sw1-GigabitEthernet0/0/4]port default vlan 40[sw1-GigabitEthernet0/0/4]int g0/0/13[sw1-GigabitEthernet0/0/13]port link-type trunk [sw1-GigabitEthernet0/0/13]port trunk allow-pass vlan all[sw1-GigabitEthernet0/0/13]int g0/0/12[sw1-GigabitEthernet0/0/12]port link-type trunk[sw1-GigabitEthernet0/0/12]port trunk allow-pass vlan all 二：设置SW２（ｖｌａｎ），设置虚拟IP并设置优先级
