基于IP子网划分VLAN
某企业拥有多种业务，如IPTV、VoIP、Internet等，每种业务使用的IP地址网段各不相同，为了便于管理，现在需要将同一种类型业务划分到同一个VLAN中；
创建VLAN：
[sw1]vlan batch 10 20 30
接口加入VLAN：
[sw1]int g0/0/4
[sw1-GigabitEthernet0/0/4]port hybrid untagged vlan 10
[sw1-GigabitEthernet0/0/4]ip-subnet-vlan enable
[sw1-GigabitEthernet0/0/4]quit
[sw1]int g0/0/5
[sw1-GigabitEthernet0/0/5]port hybrid untagged vlan 20
[sw1-GigabitEthernet0/0/5]ip-subnet-vlan enable
[sw1-GigabitEthernet0/0/5]quit
[sw1]int g0/0/6
[sw1-GigabitEthernet0/0/6]port hybrid untagged vlan 30
[sw1-GigabitEthernet0/0/6]ip-subnet-vlan enable
[sw1-GigabitEthernet0/0/6]quit
配置Trunk：
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[sw1-GigabitEthernet0/0/1]quit
[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]port link-type trunk
[sw1-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
[sw1-GigabitEthernet0/0/2]quit
[sw1]int g0/0/3
[sw1-GigabitEthernet0/0/3]port link-type trunk
[sw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 3
[sw1-GigabitEthernet0/0/3]quit
配置VLAN 10与192.168.1.2/24关联，优先级为2（0-7）：
[sw1]vlan 10
[sw1-vlan10]ip-subnet-vlan 1 ip 192.168.1.2 24 priority 2
序号 子网掩码 优先级
[sw1-vlan10]quit
[sw1]vlan 20
[sw1-vlan20]ip-subnet-vlan 1 ip 192.168.2.2 24 priority 3
[sw1-vlan20]quit
[sw1]vlan 3
[sw1-vlan30]ip-subnet-vlan 1 ip 192.168.3.2 24 priority 4
[sw1-vlan30]quit
查看IP子网绑定VLAN信息：
[sw1]display ip-subnet-vlan vlan all
