1 配置需求或说明

1.1  适用产品系列

本案例适用于如S5500V2-34S-EI、S5500V2-28F-SI、S5530F-EI-D、S5560-54C-EI、S5560X-54C-PWR-EI、S5820V2-52Q、S5820V2-52QF-H3等S5500V2、S55X0、S58X0V2系列的交换机。

1.2  配置需求及实现的效果

 为了保障语音数据能够优先转发，需要将语音电话和PC地址区分开，将语音电话地址设置成192.168.2网段划分到VLAN2，将PC地址设置成192.168.10网段划分到VLAN10，路由器器作为DHCP服务器给语音电话和PC下发IP地址。

3 配置步骤

3.1  配置交换机

#开启POE，为话机供电

<H3C>system-view

[H3C]interface GigabitEthernet1/0/1

[H3C-GigabitEthernet1/0/1]poe enable

[H3C-GigabitEthernet1/0/1]quit

#创建话机所属VLAN2以及PC所属VLAN10

[H3C]vlan 2

[H3C-vlan2]quit

[H3C]vlan 10

[H3C-vlan10]quit

#设置允许通过的OUI地址为MAC地址前缀为6ca8-4900-0000，即当报文的前缀为6ca8-4900-0000时，设备会把它当成语音报文来处理

[H3C]voice-vlan mac-address 6ca8-4900-0000 mask ffff-ff00-0000 description avaya

#将端口GigabitEthernet1/0/1设定为Hybrid端口,开启使能端口Voice VLAN功能

[H3C]interface GigabitEthernet 1/0/1

[H3C-GigabitEthernet1/0/1]port link-type hybrid

[H3C-GigabitEthernet1/0/1]voice-vlan 2 enable

#设置PC所属vlan为vlan10

[H3C-GigabitEthernet1/0/1]port hybrid pvid vlan 10

[H3C-GigabitEthernet1/0/1]port hybrid vlan 10 untagged

[H3C-GigabitEthernet1/0/1]quit

#设备连接dhcp服务器的接口1/0/17,允许VLAN2，VLAN10通过

[H3C]interface GigabitEthernet 1/0/17

[H3C-GigabitEthernet1/0/17]port link-type trunk

[H3C-GigabitEthernet1/0/17]port trunk permit vlan 2 10

[H3C-GigabitEthernet1/0/17]quit

#保存配置

[H3C]save force

3.2  配置DHCP服务器

#创建VLAN2，VLAN10及其对应的VLAN接口，为该虚接口配置IP地址

<H3C> system-view

[H3C]vlan 2

[H3C-vlan2]quit

[H3C]vlan 10

[H3C-vlan10]quit

[H3C] interface Vlan-interface 2

[H3C-Vlan-interface2]ip address 192.168.2.1 255.255.255.0

[H3C-Vlan-interface2]quit

[H3C] interface Vlan-interface 10

[H3C-Vlan-interface10]ip address 192.168.10.1 255.255.255.0

[H3C-Vlan-interface2]quit

#设备连接交换机的接口1/0/7,允许VLAN2，VLAN10通过

[H3C]interface GigabitEthernet 1/0/7

[H3C-GigabitEthernet1/0/7]port link-type trunk

[H3C-GigabitEthernet1/0/7]port trunk permit vlan 2 10

[H3C-GigabitEthernet1/0/7]quit

#设置话机VLAN2的DHCP地址池

[H3C]dhcp server ip-pool vlan2

[H3C-dhcp-pool-vlan2]network 192.168.2.0 mask 255.255.255.0

[H3C-dhcp-pool-vlan2]gateway-list 192.168.2.1

[H3C-dhcp-pool-vlan2]quit

#设置PCVLAN10的DHCP地址池

[H3C]dhcp server ip-pool vlan10

[H3C-dhcp-pool-vlan10]network 192.168.10.0 mask 255.255.255.0

[H3C-dhcp-pool-vlan10]gateway-list 192.168.10.1

[H3C-dhcp-pool-vlan10]dns-list 114.114.114.114

[H3C-dhcp-pool-vlan10]quit

#保存配置

[H3C]save force

4 实验结果验证

#交换机上查验证结果，查看话机是否加入到VLAN2
