3  配置举例

3.1  组网需求

如图1所示，AC作为DHCP服务器为AP分配IP地址，现要求使用自动AP功能，实现AP与AC自动关联，并且在关联后将AP转化为固化AP。

图1 自动AP配置举例组网图

3.2  配置步骤

3.2.1  AC的配置

(1)     配置AC的接口

# 创建VLAN 100及其对应的VLAN接口，并为该接口配置IP地址。AP将获取该IP地址与AC建立CAPWAP隧道。

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 192.1.0.1 16

[AC-Vlan-interface100] quit

# 将与Switch相连的接口GigabitEthernet1/0/1的链路类型配置为Trunk，禁止VLAN 1通过，允许VLAN 100通过，当前Trunk口的PVID为100。

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

[AC-GigabitEthernet1/0/1] port trunk pvid vlan 100

[AC-GigabitEthernet1/0/1] undo port trunk permit vlan 1

[AC-GigabitEthernet1/0/1] port trunk permit vlan 100

[AC-GigabitEthernet1/0/1] quit

(2)     配置DHCP功能

# 开启DHCP服务。

[AC] dhcp enable

# 配置DHCP地址池1为AP动态分配的网段为192.1.0.0/16，网关地址为192.1.0.1。

[AC] dhcp server ip-pool 1

[AC-dhcp-pool-1] network 192.1.0.0 16

[AC-dhcp-pool-1] gateway-list 192.1.0.1

[AC-dhcp-pool-1] quit

(3)     配置自动AP功能

# 开启自动AP功能。

[AC] wlan auto-ap enable

# 开启自动AP自动固化功能。

[AC] wlan auto-persistent enable

(4)   配置AP型号

[AC] wlan ap-group default-group 

[AC-wlan-ap-group-default-group]ap-model WA5530

3.2.2  Switch的配置

# 创建VLAN 100，用于转发AC和AP间CAPWAP隧道内的流量。

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

# 配置Switch与AC相连的GigabitEthernet1/0/1接口的属性为Trunk，禁止VLAN 1通过，允许VLAN 100通过，当前Trunk口的PVID为100。

[Switch] interface gigabitethernet 1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

[Switch-GigabitEthernet1/0/1] undo port trunk permit vlan 1

[Switch-GigabitEthernet1/0/1] port trunk permit vlan 100

[Switch-GigabitEthernet1/0/1] port trunk pvid vlan 100

[Switch-GigabitEthernet1/0/1] quit

# 配置Switch与AP相连的GigabitEthernet1/0/2接口属性为Access，当前Access口允许VLAN 100通过。

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port link-type access

[Switch-GigabitEthernet1/0/2] port access vlan 100

# 配置Switch与AP相连的GigabitEthernet1/0/2接口使能PoE功能。

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit

3.3  验证配置

# 通过display wlan ap all命令可以看到AC与AP建立连接，AP的状态为Run。

[AC] display wlan ap all

Total number of APs: 1

Total number of connected APs: 1

Total number of connected manual APs: 1

Total number of connected auto APs: 0

Total number of connected common APs: 1

Total number of connected WTUs: 0

Total number of inside APs: 0
