基于协议划分VLAN
某企业拥有多种业务，如IPTV、VoIP、Internet等，每种业务使用的协议不同，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，不同类型的业务划分到不同的VLAN中；
创建VLAN：
[sw1]vlan batch 10 20
[sw2]vlan batch 10 20
配置协议关联VLAN：
[sw2]vlan 10
[sw2-vlan10]protocol-vlan ?
INTEGER<0-15> Protocol index
at AT(AppleTalk Protocol) configuration information
ipv4 IPv4 configuration information
ipv6 IPv6 configuration information
ipx IPX(Internetwork Packet eXchange) configuration information
mode Other protocol mode configuration information
[sw2-vlan10]protocol-vlan ipv4
[sw2-vlan10]quit
[sw2]vlan 20
[sw2-vlan20]protocol-vlan ipv6
[sw2-vlan20]quit
配置接口关联协议VLAN：
[sw2]int g0/0/1
[sw2-GigabitEthernet0/0/1]protocol-vlan vlan 10 ?
INTEGER<0-15> Protocol index
all All the protocols of the VLAN
[sw2-GigabitEthernet0/0/1]protocol-vlan vlan 10 all priority ?
INTEGER<0-7> The priority ID
[sw2-GigabitEthernet0/0/1]protocol-vlan vlan 10 all priority 5
[sw2-GigabitEthernet0/0/1]quit
配置接口划入对应VLAN、配置Trunk：
[sw2]int g0/0/3
[sw2-GigabitEthernet0/0/3]port link-type trunk
[sw2-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20
[sw2-GigabitEthernet0/0/3]quit
[sw2]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type access
[sw2-GigabitEthernet0/0/1]port default vlan 10
[sw2-GigabitEthernet0/0/1]quit
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type access
[sw2-GigabitEthernet0/0/2]port default vlan 20
[sw2-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 10 20
[sw1-GigabitEthernet0/0/3]quit
[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
查看配置结果：
[sw2]display protocol-vlan interface all
/-------------------------------------------------------------------------------
Interface VLAN Index Protocol Type Priority
/-------------------------------------------------------------------------------
GigabitEthernet0/0/1 10 0 IPv4 5
GigabitEthernet0/0/2 20 0 IPv6 6
