项目四 无线网络配置（使用华为模拟器eNSP）

任务一 无线网络的基本配置

      信科公司的WLAN集群管理采用AC+FitAP的模式。在AC上面可以对AP进行基本的配置管理操作，包括向Valided AP表中添加AP、配置AP的位置信息。本任务介绍了在AC上配置AP的具体操作，网络拓扑图如图4-1所示。 

 图4-2  网络拓扑图

步骤1   安装无线路由器和无线AP，连接方式如下网络拓扑图

进行终端登录，Windows XP可以使用系统自带的管理终端进行登录，Windows 7可下载软件“SecureCRT”进行登录。登录前在“快速连接”对话框中设置软件参数并点击“连接”，如图4-3所示。 

步骤2  在AC上面对与之关联的AP进行配置。配置AP的位置信息为“cn”，代码如下： 

sys   /*进入系统视图/
             wlan  /*进入到wlan视图下/
 
             regulatory-domain-profile  name  domain1  /*创建域管理的模板，名称为domain1/
             country-code  cn   /*国家编码为cn（中国）/
 
             quit  /*返回到wlan视图下/
             ap-group  name  apg-lhh  /*创建ap管理组，组名为apg-lhh/
 
             regulatory-domain-profile  domain1  /*将域管理模板引入到apg-lhh组里/
             /返回系统视图下/
             
             wlan  /*进入到wlan视图下/
             ap  auth-mode  mac-auth  /*ap的认证方式为mac认证/
 
             ap-id  1  ap-mac  00e0-fcc6-2a10  /*ap序号为1，mac地址为00e0-fcc6-2a10 /
             ap-name  ap-wifi1  /*将此ap命名为ap-wifi1 /
 
             ap-group  apg-lhh  /*将此ap放入到apg-lhh组里/
             /返回系统视图下/

任务二  无线网络的接入 

        信科公司部署无线网络之后，陆续因无线接入出现网络故障，影响了网络的稳定。经过分析研究，公司决定把办公无线接入和来宾接入隔离，使用两个SSID标识，负载均衡，提高网络安全，网络拓扑图如图4-4所示。具体操作如下： 

图4-4  网络拓扑图 

注：云端开启步骤：

（1）双击“云朵”，使用端口选项选择GE

（2）端口映射设置

步骤1 配置出口路由器/核心交换机/AC的IP地址、端口 

（1）配置出口路由器端口 

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname AR
[AR]int g0/0/0
[AR-GigabitEthernet0/0/0]ip add 10.0.0.2 24
Oct  4 2022 19:50:58-08:00 AR %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP 
on the interface GigabitEthernet0/0/0 has entered the UP state. 
[AR-GigabitEthernet0/0/0]q
[AR]

 （2）配置AC

<AC6005>sys
Enter system view, return user view with Ctrl+Z.
[AC6005]sysname AC1
[AC1]vlan ba	
[AC1]vlan batch 10
Info: This operation may take a few seconds. Please wait for a moment...done.
[AC1]int vlan	
[AC1]int Vlanif 10
[AC1-Vlanif10]ip add 172.16.1.2 24    # 与核心交换机直连的IP地址
[AC1-Vlanif10]int g0/0/1
[AC1-GigabitEthernet0/0/1]port link-type trunk
[AC1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[AC1-GigabitEthernet0/0/1]q
[AC1]

（3） 配置核心交换机

<Huawei>sys

[Huawei]sysname LSW1
[LSW1]vlan batch 5 10


[LSW1]int vlanif 1
[LSW1-Vlanif1]ip add 10.0.0.1 24


[LSW1-Vlanif1]int vlanif 5
[LSW1-Vlanif5]ip add 192.168.0.1 24


[LSW1-Vlanif5]int vlanif 10
[LSW1-Vlanif10]ip add 172.16.1.1 24

[LSW1-Vlanif10]int g0/0/4
[LSW1-GigabitEthernet0/0/4]port link-type trunk
[LSW1-GigabitEthernet0/0/4]port trunk allow-pass vlan all

 步骤2 配置AC/出口路由器的路由，使其能相互通信。

 （1）首先AC设置静态路由

<AC1>sys
Enter system view, return user view with Ctrl+Z.
[AC1]ip route-static 0.0.0.0 0 172.16.1.1
[AC1]

（2）其次 路由器设置静态路由 

<AR>sys
Enter system view, return user view with Ctrl+Z.
[AR]ip route-static 0.0.0.0 0 10.0.0.1
[AR]

 （3）最后 在AC上测试连通性

## 在AC上ping一下路由器，测试网络是否联通：
<AC1>ping 10.0.0.2
PING 10.0.0.2: 56  data bytes, press CTRL_C to break
  Reply from 10.0.0.2: bytes=56 Sequence=1 ttl=254 time=60 ms
  Reply from 10.0.0.2: bytes=56 Sequence=2 ttl=254 time=30 ms
  Reply from 10.0.0.2: bytes=56 Sequence=3 ttl=254 time=40 ms
  Reply from 10.0.0.2: bytes=56 Sequence=4 ttl=254 time=40 ms
  Reply from 10.0.0.2: bytes=56 Sequence=5 ttl=254 time=50 ms

## 确认无误再进行下一步

步骤3 配置核心交换机DHCP，使其能分配IP地址给AP

## 配置与AP相连的端口
<Huawei>sys
[LSW1]port-group group-member g0/0/1 to g0/0/3 # 端口组
[LSW1-port-group]port link-type trunk
[LSW1-port-group]port trunk allow-pass vlan all
[LSW1-port-group]port trunk pvid vlan 5
[LSW1-port-group]quit

## 配置DHCP地址池
[LSW1]dhcp enable # 使能DHCP
[LSW1]ip pool vlan5 # 创建地址池
[LSW1-ip-pool-vlan5]network 192.168.0.0 mask 24 # 配置要分配的网段
[LSW1-ip-pool-vlan5]gateway-list 192.168.0.1 # 配置要分配的网关地址
[LSW1-ip-pool-vlan5]option 43 sub-option 3 ascii 172.16.1.2 # 将AC的IP地址下发给AP
[LSW1-ip-pool-vlan5]quit

[LSW1]int vlanif 5
[LSW1-Vlanif5]dhcp select global #在接口上下发IP地址

 查看AP的地址有没有上来；以AP1为例，双击AP设备，输入以下代码：

<Huawei>dis ip int bri

 ping一下AC看看通不通

<Huawei>ping 172.16.1.2
  PING 172.16.1.2: 56  data bytes, press CTRL_C to break
    Reply from 172.16.1.2: bytes=56 Sequence=1 ttl=254 time=30 ms
    Reply from 172.16.1.2: bytes=56 Sequence=2 ttl=254 time=30 ms
    Reply from 172.16.1.2: bytes=56 Sequence=3 ttl=254 time=20 ms
    Reply from 172.16.1.2: bytes=56 Sequence=4 ttl=254 time=40 ms
    Reply from 172.16.1.2: bytes=56 Sequence=5 ttl=254 time=30 ms

  --- 172.16.1.2 ping statistics ---
    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 20/30/40 ms

 确认无误，进行下一步

步骤4   注册AP

注：以下配置，可能会弹出的警告，都选Y。

<AC1>sys
Enter system view, return user view with Ctrl+Z.	
#指定capwap协议的信令源地址
[AC1]capwap source interface Vlanif 10
[AC1]wlan   # 进入wlan视图	
[AC1-wlan-view]ap auth-mode mac-auth  # 配置AC的验证方式为MAC验证

## 创建域配置并配置国家码，使AP的射频特性符合国家的法律法规要求
[AC1-wlan-view]regulatory-domain-profile name CN  # 创建域配置
	
[AC1-wlan-regulate-domain-CN]country-code CN  # 国家码：中国
Info: The current country code is same with the input country code.
[AC1-wlan-regulate-domain-CN]q

## 创建AP-group
	
[AC1-wlan-view]ap-group name guest    # 创建guest组

	
[AC1-wlan-ap-group-guest]regulatory-domain-profile CN  # 关联刚才的域配置
Warning: Modifying the country code will clear channel, power and antenna gain c
onfigurations of the radio and reset the AP. Continue?[Y/N]:y
[AC1-wlan-ap-group-guest]q
	
[AC1-wlan-view]ap-group name work  # 创建work组
Info: This operation may take a few seconds. Please wait for a moment.done.
	
[AC1-wlan-ap-group-work]regulatory-domain-profile CN  # 关联刚才的域配置
Warning: Modifying the country code will clear channel, power and antenna gain c
onfigurations of the radio and reset the AP. Continue?[Y/N]:y
[AC1-wlan-ap-group-work]q

 查看AP的MAC地址如下:

(1)依次双击AP1，AP2,AP3,输入指令：

将mac地址复制备用：

AP1：00e0-fc54-49d0 

 AP2:  00e0-fc4d-4a80 

AP3： 00e0-fc15-5570

## 基于mac地址注册AP
<AC1>sys
Enter system view, return user view with Ctrl+Z.
[AC1]wlan
[AC1-wlan-view]ap-id 1 ap-mac 00e0-fc54-49d0    # 加入AP。mac地址可以通过查看核心交换机的mac地址表，或者右键AP打开设置查看
[AC1-wlan-ap-1]ap-name guest1  # 将AP名字更改为guest1
[AC1-wlan-ap-1]ap-group guest  # 将AP加入刚才配置的guest组
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 c
ontinue? [Y/N]:y
Info: This operation may take a few seconds. Please wait for a moment.. done.
[AC1-wlan-ap-1]q
[AC1-wlan-view]ap-id 2 ap-mac 00e0-fc4d-4a80
[AC1-wlan-ap-2]ap-name guest2
[AC1-wlan-ap-2]ap-group guest
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 c
ontinue? [Y/N]:y
Info: This operation may take a few seconds. Please wait for a moment.. done.
[AC1-wlan-ap-2]q
[AC1-wlan-view]ap-id 3 ap-mac 00e0-fc15-5570
[AC1-wlan-ap-3]ap-name work1
[AC1-wlan-ap-3]ap-group work
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 c
ontinue? [Y/N]:y
Info: This operation may take a few seconds. Please wait for a moment.. done.
[AC1-wlan-ap-3]q
[AC1-wlan-view]

 注： 到此处AP会自动重启，且AP名字会被更改（如果没有自动重启，可以自己手动重启） ； 重启完在AC上查看AP是否注册成功： 

<AC1>
<AC1>sys
Enter system view, return user view with Ctrl+Z.
[AC1]wlan
[AC1-wlan-view]dis ap all
Info: This operation may take a few seconds. Please wait for a moment.done.
