1 配置需求或說明

1.1  適用產品係列

本案例適用於如S5120V2-52P-LI、S5120V2-28P-SI、S5130-52S-EI、S5130S-28S-EI、S5150X-16ST-EI等S5120V2、S5130、S5150係列的交換機。

1.2  配置需求及實現的效果

 為了保障語音數據能夠優先轉發，需要將語音電話和PC地址區分開，將語音電話地址設置成192.168.2網段劃分到VLAN2，將PC地址設置成192.168.10網段劃分到VLAN10，路由器器作為DHCP服務器給語音電話和PC下發IP地址。

3 配置步驟

3.1  配置交換機

#開啟POE，為話機供電

system-view

[H3C]interface GigabitEthernet1/0/1

[H3C-GigabitEthernet1/0/1]poe enable

[H3C-GigabitEthernet1/0/1]quit

#創建話機所屬VLAN2以及PC所屬VLAN10

[H3C]vlan 2

[H3C-vlan2]quit

[H3C]vlan 10

[H3C-vlan10]quit

#設置允許通過的OUI地址為MAC地址前綴為6ca8-4900-0000，即當報文的前綴為6ca8-4900-0000時，設備會把它當成語音報文來處理

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

#將端口GigabitEthernet1/0/1設定為Hybrid端口,開啟使能端口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

#設置PC所屬vlan為vlan10

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

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

[H3C-GigabitEthernet1/0/1]quit

#設備連接dhcp服務器的接口1/0/17,允許VLAN2，VLAN10通過

[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服務器

#創建VLAN2，VLAN10及其對應的VLAN接口，為該虛接口配置IP地址

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

#設備連接交換機的接口1/0/7,允許VLAN2，VLAN10通過

[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

#設置話機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

#設置PCVLAN10的DHCP地址池

[H3C-dhcp-pool-vlan10]quit

#保存配置

[H3C]save force

4 實驗結果驗證

#交換機上查驗證結果，查看話機是否加入到VLAN2
