2.18.1  动态分配地址典型配置举例

1. 组网需求

·     作为DHCP服务器的AC为网段10.1.1.0/24中的AP和客户端动态分配IP地址，该地址池网段分为两个子网网段：10.1.1.0/25和10.1.1.128/25；

·     AC的两个VLAN接口，VLAN接口10和VLAN接口20的地址分别为10.1.1.1/25和10.1.1.129/25；

·     为AP分配10.1.1.0/25网段的IP地址，为Client分配10.1.1.128/25网段的IP地址。

3. 配置步骤

(1)     配置端口属于VLAN及对应VLAN接口的IP地址

# 创建VLAN10和VLAN20。

<AC> system-view

[AC] vlan 10

[AC-vlan10] quit

[AC] vlan 20

[AC-vlan20] quit

# 将与AP连接的接口加入VLAN10、VLAN20中。

[AC] interface gigabitethernet 1/0/3

[AC-GigabitEthernet1/0/3] port link-type trunk

[AC-GigabitEthernet1/0/3] port trunk permit vlan 10 20

[AC-GigabitEthernet1/0/3] port trunk pvid vlan 10

[AC-GigabitEthernet1/0/3] quit

# 配置VLAN10和VLAN20接口的IP地址。

[AC] interface vlan-interface 10

[AC-Vlan-interface10] ip address 10.1.1.1 25

[AC-Vlan-interface10] quit

[AC] interface vlan-interface 20

[AC-Vlan-interface20] ip address 10.1.1.129 25

[AC-Vlan-interface20] quit

(2)     配置无线服务

# 配置无线服务模板并把服务模板加入VLAN20中。

[AC] wlan service-template service

[AC-wlan-st-service] ssid service

[AC-wlan-st-service] vlan 20

[AC-wlan-st-service] service-template enable

[AC-wlan-st-service] quit

# 配置AP。

[AC] wlan ap ap1 model WA6320

[AC-wlan-ap-ap1] serial-id 219801A28N819CE0002T

[AC-wlan-ap-ap1] radio 1

[AC-wlan-ap-ap1-radio-1] service-template service

[AC-wlan-ap-ap1-radio-1] radio enable

[AC-wlan-ap-ap1-radio-1] quit

[AC-wlan-ap-ap1] quit

(3)     配置DHCP服务

# 开启DHCP服务。

[AC] dhcp enable

# 配置VLAN接口10和VLAN接口20工作在DHCP服务器模式。

[AC] interface vlan-interface 10

[AC-Vlan-interface10] dhcp select server

[AC-Vlan-interface10] quit

[AC] interface vlan-interface 20

[AC-Vlan-interface20] dhcp select server

[AC-Vlan-interface20] quit

# 配置DHCP地址池1，用来为10.1.1.0/25网段内的客户端分配IP地址和网络配置参数。

[AC] dhcp server ip-pool 1

[AC-dhcp-pool-1] network 10.1.1.0 mask 255.255.255.128

[AC-dhcp-pool-1] quit

# 配置DHCP地址池2，用来为10.1.1.128/25网段内的客户端分配IP地址和网络配置参数。

[AC] dhcp server ip-pool 2

[AC-dhcp-pool-2] network 10.1.1.128 mask 255.255.255.128

[AC-dhcp-pool-2] quit
