HCIA | WLAN二层旁挂组网实验

一、前言

    本实验是WLAN二层旁挂模式进行组网的实验；在本实验中，网络流量的传递直接经过交换机发往上层网络，不再经过AC。

    通过该实验，可以学习WLAN二层组网的配置方式、理解旁挂式组网的优点，并掌握基本的WLAN业务配置方法。

二、实验拓扑

    本次实验的实验拓扑如下：

三、配置思路

    基本的二层旁挂式组网包括三步：

** ① 配置网络互通**

** ② 配置AP上线**

** ③ 配置WLAN业务**

四、实验过程

（一）配置网络互通

Step1：二层网络互通配置

** ① LSW1的VLAN划分**

[S1]vlan batch 10 20 30 
[S1]int g0/0/1
[S1-GigabitEthernet0/0/1]port link-type access 
[S1-GigabitEthernet0/0/1]port default vlan 30
[S1-GigabitEthernet0/0/1]int g0/0/2
[S1-GigabitEthernet0/0/2]port link-type trunk 
[S1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 
[S1-GigabitEthernet0/0/2]int g0/0/3
[S1-GigabitEthernet0/0/3]port link-type trunk 
[S1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20 

** ② LSW2的VLAN划分**

[S2]vlan batch 10 20 
[S2]interface g0/0/1
[S2-GigabitEthernet0/0/1]port link-type trunk 
[S2-GigabitEthernet0/0/1]port trunk pvid vlan 10
[S2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[S2-GigabitEthernet0/0/1]int g0/0/2
[S2-GigabitEthernet0/0/2]port link-type trunk 
[S2-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20 
[S2-GigabitEthernet0/0/2]port trunk pvid vlan 10
[S2-GigabitEthernet0/0/2]int g 0/0/3
[S2-GigabitEthernet0/0/3]port link-type trunk 
[S2-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20

** ③ AC的VLAN划分 **

[AC1]interface g0/0/1
[AC1-GigabitEthernet0/0/1]port link-type trunk 
[AC1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10

Step2：三层网络互通

** ① LSW1的IP地址配置 **

[S1]interface Vlanif 20
[S1-Vlanif20]ip address 10.1.20.1 24
[S1-Vlanif20]int vlanif 30
[S1-Vlanif30]ip ad 10.1.30.2 24

** ② AC的IP地址配置**

[AC1]vlan 10
[AC1]interface Vlanif 10
[AC1-Vlanif10]ip ad 10.1.10.1 24

** ③ R1的接口IP及路由配置**

[R1]interface g0/0/1
[R1-GigabitEthernet0/0/1]ip ad 10.1.30.1 24
[R1-GigabitEthernet0/0/1]q
[R1]ip route-static 10.1.20.0 24 10.1.30.2 

（二）配置AP上线

Step1：IP 地址池配置

** ① LSW1上使能DHCP并配置接口地址池**

[S1]dhcp enable 
[S1]interface Vlanif 20
[S1-Vlanif20]dhcp select interface 

** ② AC上使能DHCP并配置接口地址池**

[AC1]dhcp enable 
[AC1]interface Vlanif 10
[AC1-Vlanif10]dhcp select interface 

Step2：配置AC源接口地址并选择合适的AP认证方式使AP正常上线

** ① 配置AC源接口**

[AC1]capwap source ip-address 10.1.10.1 

** ② 在AC上创建AP组**

[AC1]wlan 
[AC1-wlan-view]ap-group name HUAWEI

** ③ 配置AP方式为不认证，并等待AP上线**

[AC1]wlan 
[AC1-wlan-view]ap auth-mode no-auth 

** ④ 查询AP上线状态**

[AC1]display ap all
Info: This operation may take a few seconds. Please wait for a moment.done.
Total AP information:
nor : normal [2]

---

---

ID MAC Name Group IP Type State STA
Uptime

---

---

0 00e0-fc79-72f0 00e0-fc79-72f0 default 10.1.10.244 AP6050DN nor 0
20S
1 00e0-fc4a-2780 00e0-fc4a-2780 default 10.1.10.46 AP6050DN nor 0
13S

---

---

Total: 2

** 注：该状态显示两台AP均已上线**

** ⑤ 将两台AP分别命名为AP1和AP2，并加入AP组**

[AC1]wlan 
[AC1-wlan-view]ap-group
[AC1-wlan-view]ap-id 0 
[AC1-wlan-ap-0]ap-name AP1
[AC1-wlan-ap-0]ap-group HUAWEI
[AC1-wlan-ap-0]ap-id 1
[AC1-wlan-ap-1]ap-name AP2
[AC1-wlan-ap-1]ap-group HUAWEI

** ⑥ 查看配置是否生效**

**[AC1-wlan-view]display ap all **
Info: This operation may take a few seconds. Please wait for a moment.done.
Total AP information:
fault: fault [2]

---

ID MAC Name Group IP Type State STA Uptime

0 00e0-fc79-72f0 AP1 HUAWEI - AP6050DN fault 0 -
1 00e0-fc4a-2780 AP2 HUAWEI - AP6050DN fault 0 -

---

Total: 2

** ⑦ 将AP认证方式切换为mac认证**

[AC1]wlan 
[AC1-wlan-view]ap auth-mode mac-auth 

**注：这是为了前面配置了无需认证，但为了防止非法AP接入，所以需要将认证方式切换为MAC。 **

（三）配置WLAN业务

Step1：创建SSID模板SFN，并设置SSID为SFN

[AC1]wlan 
[AC1-wlan-view]ssid-profile name SFN
[AC1-wlan-ssid-prof-SFN]ssid SFN

Step2：创建安全模板SFN，并设置密码

[AC1-wlan-view]security-profile name SFN
[AC1-wlan-sec-prof-SFN]security wpa-wpa2 psk pass-phrase a1234567 aes

Step3：创建VAP模板SFN，并绑定SSID和安全模板，设置业务VLAN和转发方式

[AC1-wlan-view]vap-profile name SFN
[AC1-wlan-vap-prof-SFN]security-profile SFN
[AC1-wlan-vap-prof-SFN]service-vlan vlan-id 20
[AC1-wlan-vap-prof-SFN]forward-mode direct-forward 

Step4：创建域管理模板SFN，并设置国家码为CN

[AC1-wlan-view]regulatory-domain-profile name SFN
[AC1-wlan-regulate-domain-SFN]country-code CN 

Step5：进入AP组，并绑定域管理模板和VAP模板

[AC1-wlan-view]ap-group name HUAWEI
[AC1-wlan-ap-group-HUAWEI]regulatory-domain-profile SFN
[AC1-wlan-ap-group-HUAWEI]vap-profile SFN wlan 1 radio all 

五、结果验证

① ENSP界面

** **在AC配置完成后，ensp中AP显示变为了如下的图形界面，表示已经成功释放双频信号、

② 终端连接到AP后，检测其和R1的连通性

    显示如下： 

**该效果表示，STA能够实现与R1的正常通信，连通性正常。 **
