交换机的三层交换使用

三层交换意思就是让不同的vlan通信；隔离故障的同时实现正常通信。

PC1—IP配值

PC2—IP配值

在交换机2中创建vlan10 和 vlan 20 并将PC1加入vlan10(g0/0/1),PC2加入vlan20(g0/0/2)；
交换机2的g0/0/3端口和交换机1的g0/0/1端口各设置为trunk；

Huawei]vlan 10
[Huawei-vlan10]q
[Huawei]vlan 20
[Huawei-vlan20]q
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access
[Huawei-GigabitEthernet0/0/1]port default vlan 10
[Huawei-GigabitEthernet0/0/1]q
[Huawei]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 20
[Huawei-GigabitEthernet0/0/2]dis vlan
The total number of vlans is : 3
