AC+AP配置

您好，只要网络可达就可

可参考如下AC+AP的配置举例：

1.19.1  通过DHCP发现方式建立CAPWAP隧道配置举例

1. 组网需求

AP通过DHCP选项方式从DHCP server上获取AP和AC的IP地址，发现AC并与AC建立CAPWAP隧道连接。

2. 组网图

图1-3 通过DHCP发现方式建立CAPWAP隧道组网图

‌

3. 配置步骤

(1)     配置DHCP server

# 使能DHCP服务器功能。

<DHCP Server> system-view

[DHCP Server] dhcp enable

# 配置DHCP地址池1。

[DHCP Server] dhcp server ip-pool 1

[DHCP Server-dhcp-pool-1] network 1.1.1.0 mask 255.255.255.0

# 通过自定义选项的方式配置Option 43的内容，为AP指定AC的IP地址1.1.1.3，注意Option 43选项内容中最后四字节为01010103（1.1.1.3），即为AC的IP地址。

[DHCP Server-dhcp-pool-1] option 43 hex 800700000101010103

[DHCP Server-dhcp-pool-1] quit

[DHCP Server] quit

(2)     配置AC

# 配置AC的VLAN-interface 1的IP地址为1.1.1.3/24。

<AC> system-view

[AC] interface vlan-interface 1

[AC-Vlan-interface1] ip address 1.1.1.3 24

# 创建手工AP，名称为ap1，配置序列号为210235A1BSC123000050。

[AC] wlan ap ap1 model WA4320i-ACN

[AC-wlan-ap-ap1] serial-id 210235A1BSC123000050

[AC-wlan-ap-ap1] quit

# AP启动后，DHCP server会给AP自动分配IP地址1.1.1.2，同时由于Option 43选项携带AC的IP地址1.1.1.3。AP拥有了自动分配的本地IPv4地址和需要建立关联的AC的IP地址1.1.1.3，就会开始发现AC的过程并建立CAPWAP隧道。

4. 验证配置

# 查看AP的详细信息，可以看到AP与AC成功建立隧道连接并进入Run状态，发现方式为DHCP选项方式。
