H3C vlan配置：
单交换机VLAN：
SW1:
system-view
vlan 2
port e0/4/1
port e0/4/2
quit
vlan 3
port e0/4/3
port e0/4/4
quit
display vlan all
删除VLAN：
undo vlan 2
undo vlan 3
另外的一种做法：
SW1:
system-view
vlan 2
quit
vlan 3
quit
interface e0/4/1
port access vlan 2
quit
port access vlan 2
quit
interface e0/4/3
port access vlan 3
quit
interface e0/4/4
port access vlan 3
quit
display vlan all
多交换机VLAN：
SW1:
system-view
vlan 2
port e0/4/2
quit
vlan 3
port e0/4/1
quit
interface e0/4/3
port link-type trunk
port trunk permit vlan all
quit
SW2:
system-view
vlan 2
port e0/4/6
quit
vlan 3
port e0/4/5
quit
interface e0/4/3
port link-type trunk
port trunk permit vlan all
quit
VLAN 基本实验完成。
