[sw1-Ethernet0/0/2]port link-type access                设置接口类型为access
[sw1-Ethernet0/0/2]port defa vlan 10                        给接口划分vlan
[sw1-Ethernet0/0/2]int e0/0/1
[sw1-Ethernet0/0/1]port link-type access
[sw1-Ethernet0/0/1]port defa vlan 20
[sw1-Ethernet0/0/1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk                        设置接口类型为trunk
[sw1-GigabitEthernet0/0/1]port trunk all vlan all                        允许所有vlan通过

路由器配置

<Huawei>sys                        
Enter system view, return user view with Ctrl+Z.
[Huawei]undo info-center en                        关闭命令提示

[Huawei]sys r1                        修改名字
[r1]int g0/0/0.1                进入子接口
[r1-GigabitEthernet0/0/0.1]vlan-type dot1q 10 default  配置vlan10
[r1-GigabitEthernet0/0/0.1]ip add 192.168.10.254 24  配置vlan10网关
[r1-GigabitEthernet0/0/0.1]int g0/0/0.2
[r1-GigabitEthernet0/0/0.2]vlan-type dot1q 20 default
[r1-GigabitEthernet0/0/0.2]ip add 192.168.20.254 24
