组网需求（适宜群体）

某企业分支机构规模较小，为了保证工作人员可以随时随地的访问公司网络，通过部署小型WLAN网络实现移动办公。如图所示，AC通过PoE交换机与AP连接，PoE交换机为AP供电。通过在AC上配置WLAN业务的相关内容，下发给AP生成WLAN网络供用户接入。

配置思路

  1. 配置AP、AC、SwitchA和上层网络设备之间实现二层互通。
  2. 配置AC作为DHCP服务器为STA和AP分配IP地址。
  3. 配置AP上线。
    1. 创建AP组，用于将需要进行相同配置的AP都加入到AP组，实现统一配置。
    2. 配置AC的系统参数，包括国家码、AC与AP之间通信的源接口。
    3. 配置AP上线的认证方式并离线导入AP，实现AP正常上线。
  4. 配置WLAN业务参数，实现STA访问WLAN网络功能。

操作步骤

  1. 在AC上配置NAC模式为统一模式（缺省值，不需配置）。配置SwitchA和AC，使AP与AC之间能够传输CAPWAP报文

    配置SwitchA连接AP的接口GE0/0/1加入VLAN100（管理VLAN），SwitchA连接AC的接口 GE0/0/2加入VLAN100。
<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 100
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type trunk
[SwitchA-GigabitEthernet0/0/1] port trunk pvid vlan 100
[SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
[SwitchA-GigabitEthernet0/0/1] undo port trunk allow-pass vlan 1
[SwitchA-GigabitEthernet0/0/1] stp edged-port enable
[SwitchA-GigabitEthernet0/0/1] port-isolate enable
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type trunk
[SwitchA-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
[SwitchA-GigabitEthernet0/0/2] undo port trunk allow-pass vlan 1
[SwitchA-GigabitEthernet0/0/2] quit
配置AC连接SwitchA的接口GE1/0/1加入VLAN100。
<HUAWEI> system-view
[HUAWEI] sysname AC
[AC] vlan batch 100 101
[AC] interface gigabitethernet 1/0/1
[AC-GigabitEthernet1/0/1] port link-type trunk
[AC-GigabitEthernet1/0/1] port trunk allow-pass vlan 100
[AC-GigabitEthernet1/0/1] undo port trunk allow-pass vlan 1
[AC-GigabitEthernet1/0/1] quit

2.配置AC与上层网络设备互通

说明：根据实际组网情况在AC上行口配置业务VLAN透传，和上行网络设备互通。

配置AC上行接口GE1/0/2加入VLAN101（业务VLAN）。
[AC] interface gigabitethernet 1/0/2
[AC-GigabitEthernet1/0/2] port link-type trunk
[AC-GigabitEthernet1/0/2] port trunk allow-pass vlan 101
[AC-GigabitEthernet1/0/2] undo port trunk allow-pass vlan 1
[AC-GigabitEthernet1/0/2] quit

3.配置AC作为DHCP服务器，为STA和AP分配IP地址

配置基于接口地址池的DHCP服务器，其中，VLANIF100接口为AP提供IP地址，VLANIF101为STA提供IP地址。
说明：DNS服务器地址请根据实际需要配置。常用配置方法如下：
  • 接口地址池场景，需要在VLANIF接口视图下执行命令[dhcp server dns-list] ip-address &<1-8>。
  • 全局地址池场景，需要在IP地址池视图下执行命令[dns-list] ip-address &<1-8>。
[AC] dhcp enable  //使能DHCP功能
[AC] interface vlanif 100
[AC-Vlanif100] ip address 10.23.100.1 24
[AC-Vlanif100] dhcp select interface  //配置基于接口的地址池
[AC-Vlanif100] quit
[AC] interface vlanif 101
[AC-Vlanif101] ip address 10.23.101.1 24
[AC-Vlanif101] dhcp select interface
[AC-Vlanif101] quit

4.配置AP上线

创建AP组，用于将相同配置的AP都加入同一AP组中。
[AC] wlan
[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] quit
创建域管理模板，在域管理模板下配置AC的国家码并在AP组下引用域管理模板。
[AC-wlan-view] regulatory-domain-profile name domain1
[AC-wlan-regulate-domain-domain1] country-code cn
[AC-wlan-regulate-domain-domain1] quit
[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] regulatory-domain-profile domain1
Warning: This configuration change will clear the channel and power configurations of radios, and may restart APs. Continue?[Y/N]:y  
[AC-wlan-ap-group-ap-group1] quit
[AC-wlan-view] quit
配置AC的源接口。
[AC] capwap source interface vlanif 100
在AC上离线导入AP，并将AP加入AP组“ap-group1”中。假设AP的MAC地址为00e0-fc11-1111，并且根据AP的部署位置为AP配置名称，便于从名称上就能够了解AP的部署位置。例如MAC地址为00e0-fc11-1111的AP部署在1号区域，命名此AP为area_1。
说明：ap auth-mode命令缺省情况下为MAC认证，如果之前没有修改其缺省配置，可以不用执行ap auth-mode mac-auth。举例中使用的AP具有射频0和射频1两个射频。射频0为2.4GHz射频，射频1为5GHz射频。
[AC] wlan
[AC-wlan-view] ap auth-mode mac-auth
[AC-wlan-view] ap-id 0 ap-mac 00e0-fc11-1111
[AC-wlan-ap-0] ap-name area_1
[AC-wlan-ap-0] ap-group ap-group1
Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configuration s of the radio, Whether to continue? [Y/N]:y  
[AC-wlan-ap-0] quit
将AP上电后，当执行命令display ap all查看到AP的“State”字段为“nor”时，表示AP正常上线。
[AC-wlan-view] display ap all

Total AP information: 
nor  : normal          [1] 
Extrainfo : Extra information 
P  : insufficient power supply 
-------------------------------------------------------------------------------------------------- 
ID   MAC            Name   Group     IP            Type            State STA Uptime      ExtraInfo 
-------------------------------------------------------------------------------------------------- 
0    00e0-fc11-1111 area_1 ap-group1 10.23.100.254 AP5030DN        nor   0   10S         - 
-------------------------------------------------------------------------------------------------- 
Total: 1

5.配置WLAN业务参数

创建名为“wlan-security”的安全模板，并配置安全策略。
说明：举例中以配置WPA2+PSK+AES的安全策略为例，密码为“YsHsjx_202206”，实际配置中请根据实际情况，配置符合实际要求的安全策略。
[AC-wlan-view] security-profile name wlan-security
[AC-wlan-sec-prof-wlan-security] security wpa2 psk pass-phrase YsHsjx_202206 aes  //配置安全策略为WPA2+PSK+AES
[AC-wlan-sec-prof-wlan-security] quit
创建名为“wlan-ssid”的SSID模板，并配置SSID名称为“wlan-net”。
[AC-wlan-view] ssid-profile name wlan-ssid
[AC-wlan-ssid-prof-wlan-ssid] ssid wlan-net  //配置SSID名称为wlan-net
[AC-wlan-ssid-prof-wlan-ssid] quit
创建名为“wlan-vap”的VAP模板，配置业务数据转发模式、业务VLAN，并且引用安全模板和SSID模板。
[AC-wlan-view] vap-profile name wlan-vap
[AC-wlan-vap-prof-wlan-vap] forward-mode tunnel  //配置业务转发模式为隧道转发
[AC-wlan-vap-prof-wlan-vap] service-vlan vlan-id 101  //缺省情况下VLAN ID为1，修改VLAN ID为101
[AC-wlan-vap-prof-wlan-vap] security-profile wlan-security
[AC-wlan-vap-prof-wlan-vap] ssid-profile wlan-ssid
[AC-wlan-vap-prof-wlan-vap] quit
配置AP组引用VAP模板，AP上射频0和射频1都使用VAP模板“wlan-vap”的配置。
[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] vap-profile wlan-vap wlan 1 radio 0
[AC-wlan-ap-group-ap-group1] vap-profile wlan-vap wlan 1 radio 1
[AC-wlan-ap-group-ap-group1] quit

6.提交配置

[AC-wlan-view] commit all
Warning: Committing configuration may cause service interruption, continue?[Y/N]:y

7.验证配置结果

配置完成后，通过执行命令display vap ssid wlan-net查看如下信息，当“Status”项显示为“ON”时，表示AP对应的射频上的VAP已创建成功。
[AC-wlan-view] display vap ssid wlan-net
WID : WLAN ID
--------------------------------------------------------------------------------
AP ID AP name RfID WID     BSSID          Status  Auth type     STA   SSID
--------------------------------------------------------------------------------
0     area_1  0    1       00E0-FC11-1111 ON      WPA2-PSK      0     wlan-net
0     area_1  1    1       00E0-FC11-1112 ON      WPA2-PSK      0     wlan-net
-------------------------------------------------------------------------------
Total: 2
STA搜索到名为“wlan-net”的无线网络，输入密码“YsHsjx_202206”并正常关联后，在AC上执行display station ssid wlan-net命令，可以查看到用户已经接入到无线网络“wlan-net”中。
[AC-wlan-view] display station ssid wlan-net
