实验拓扑图

配置流程

基础配置

1. LSW2交换机配置

接入层交换机和AP/汇聚层交换机的链路应该是Trunk类型

# S2 Eth0/0/1配置
[S2]interface Ethernet 0/0/1
[S2-Ethernet0/0/1]port link-type trunk
[S2-Ethernet0/0/1]port trunk pvid vlan 100
[S2-Ethernet0/0/1]port trunk allow-pass vlan 100

# S2 Eth0/0/3配置
[S2]interface Ethernet 0/0/3
[S2-Ethernet0/0/3]port link-type trunk
[S2-Ethernet0/0/3]port trunk pvid vlan 100
[S2-Ethernet0/0/3]port trunk allow-pass vlan 100

# S2 Eth0/0/2配置
[S2]interface Ethernet 0/0/2
[S2-Ethernet0/0/2]port link-type trunk
[S2-Ethernet0/0/2]port trunk allow-pass vlan 100

2. LSW1交换机配置

# 创建相应的vlan
[S1]vlan batch 100 to 101

# 0/0/1接口与接入层交换机相连，配置相应的trunk模式
[S1]interface GigabitEthernet 0/0/1
[S1-GigabitEthernet0/0/1]port link-type trunk
[S1-GigabitEthernet0/0/1]port trunk allow-pass vlan 100

# 0/0/2接口和AC相连，配置好接口相应的链路类型
[S1]interface GigabitEthernet 0/0/2
[S1-GigabitEthernet0/0/2]port link-type trunk
# 这个trunk口需要通过100和101；因为到时候数据会发到AC这边
[S1-GigabitEthernet0/0/2]port trunk allow-pass vlan 100 to 101

# 用vlanif101做三层接口
[S1]interface Vlanif101
[S1-Vlanif101]ip address 10.23.101.254 255.255.255.0

3. AC相应接口的配置

# 创建相应的vlan
<AC6005>system-view
[AC6005]sysname AC
[AC]vlan batch 100 to 101

# 配置0/0/1接口
[AC]interface gigabitethernet0/0/1
[AC-GigabitEthernet0/0/1]port link-type trunk
[AC-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 to 101

# 用vlanif100做三层接口
[AC]interface Vlanif100
[AC-Vlanif100]ip address 10.23.100.1 255.255.255.0

# 将AC作为DHCP服务器，为AP发放IP地址
[AC]dhcp enable
[AC]interface vlanif100
[AC-Vlanif100]dhcp select interface # 选择基于接口配置

# 业务的DHCP服务器放在交换机1上。为终端设备分发IP地址。
[S1]dhcp enable
[S1]interface Vlanif101
[S1-Vlanif101]dhcp select interface

在AC中做AP的上线

1. AC的配置

[AC]wlan # 进入wlan视图
[AC-wlan-view]regulatory-domain-profile name wlan # 配置管理模板
[AC-wlan-regulate-domain-wlan]country-code CN # 配置国家码

2. 把域管理模板和AP组做关联

[AC]wlan  # 进入wlan视图
[AC-wlan-view]ap-group name ap  #先进入ap组 
[AC-wlan-ap-group-ap]regulatory-domain-profile wlan  # 将管理模板引入ap组
Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continue?[Y/N]:y

3. 创建AC未来要和AP通信的接口；也就是创建控制隧道／数据隧道

[AC]capwap source interface vlanif100  # 配置AC与AP建立capwap隧道的源接口。

4. 把AP添加到AC上去。

# 第一步做AP1和AP2的认证
[AC]wlan
[AC-wlan-view]ap auth-mode mac-auth
[AC-wlan-view]ap-id 1 ap-mac 00e0-fc7e-0310
[AC-wlan-ap-1]q
[AC-wlan-view]ap-id 2 ap-mac 00e0-fccf-5170

# 对AP1做相应配置
[AC-wlan-view]ap-id 1
[AC-wlan-ap-1]ap-name ap1 # 给ap1起个名字
[AC-wlan-ap-1]ap-group ap # 将ap跟ap组进行绑定
Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to continue? [Y/N]:y

# 对AP2做相应配置
[AC-wlan-view]ap-id 2
[AC-wlan-ap-2]ap-name ap2 # 给ap2起个名字
[AC-wlan-ap-2]ap-group ap # 将ap跟ap组进行绑定
Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to continue? [Y/N]:y

5. 接下来要查看ap上线

[AC]dis ap all   # 查看ap上线，如果上线了，状态就为nor

wlan下发

# 配置安全模板
[AC]wlan
[AC-wlan-view]security-profile name security # 设置安全模板
[AC-wlan-sec-prof-security]security wpa2 psk pass-phrase 12345678 aes # 选择认证方式

# 配置SSID模板
[AC-wlan-view]ssid-profile name ssid # 创建ssid模板
[AC-wlan-ssid-prof-ssid]ssid wifi123 # 配置你的无线的名字

# 配置vap模板
[AC]wlan
[AC-wlan-view]vap-profile name vap # 创建vap模板
[AC-wlan-vap-prof-vap]forward-mode tunnel # 配置转发的模式为tunnel
[AC-wlan-vap-prof-vap]service-vlan vlan-id 101 # 配置业务vlan
[AC-wlan-vap-prof-vap]security-profile security # 安全的策略模板加入vap模板
[AC-wlan-vap-prof-vap]ssid-profile ssid # 将ssid模板加入vap模板

# 将wap的模板推给ap组
[AC-wlan-view]ap-group name ap # 先进入ap组
[AC-wlan-ap-group-ap]vap-profile vap wlan 1 radio 0 # 1是wlan的id；radio是射频信号；射频信号是支持0-2
[AC-wlan-ap-group-ap]vap-profile vap wlan 1 radio 1

# 对AP2也进行同样的操作
[AC-wlan-view]ap-group name ap
[AC-wlan-ap-group-ap]vap-profile vap wlan 2 radio 0
[AC-wlan-ap-group-ap]vap-profile vap wlan 2 radio 1

验证过程

1. PC可以接收到AP的信号
   
2. 点击连接，输入密码
   
3. 连接成功后可查看到信号
   
4. 当PC1和PC2都成功连接上AP之后，查看两台PC的IP地址
   PC1：
   
   PC2：
   
5. PC1 ping PC2，能够正常通信
