配置思路
- 配置AP、AC和周边网络设备之间实现网络互通。
- 配置AP上线。
- 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。
- 配置AC的系统参数，包括国家码、AC与AP之间通信的源接口。
- 配置AP上线的认证方式并离线导入AP，实现AP正常上线。
- 配置WLAN业务参数，实现STA访问WLAN网络功能。
配置注意事项
- 纯组播报文由于协议要求在无线空口没有ACK机制保障，且无线空口链路不稳定，为了纯组播报文能够稳定发送，通常会以低速报文形式发送。如果网络侧有大量异常组播流量涌入，则会造成无线空口拥堵。为了减小大量低速组播报文对无线网络造成的冲击，建议配置组播报文抑制功能。配置前请确认是否有组播业务，如果有，请谨慎配置限速值。
- 业务数据转发方式采用直接转发时，建议在直连AP的交换机接口上配置组播报文抑制。
- 业务数据转发方式采用隧道转发时，建议在AC的流量模板下配置组播报文抑制。
建议在与AP直连的设备接口上配置端口隔离，如果不配置端口隔离，尤其是业务数据转发方式采用直接转发时，可能会在VLAN内形成大量不必要的广播报文，导致网络阻塞，影响用户体验。
隧道转发模式下，管理VLAN和业务VLAN不能配置为同一VLAN，且AP和AC之间只能放通管理VLAN，不能放通业务VLAN。
操作步骤
- 配置周边设备# 配置接入交换机Switch的GE0/0/1和GE0/0/2接口加入VLAN100，GE0/0/1的缺省VLAN为VLAN100。
<HUAWEI> system-view [HUAWEI] sysname Switch [Switch] vlan batch 100 [Switch] interface gigabitethernet 0/0/1 [Switch-GigabitEthernet0/0/1] port link-type trunk [Switch-GigabitEthernet0/0/1] port trunk pvid vlan 100 [Switch-GigabitEthernet0/0/1] port trunk allow-pass vlan 100 [Switch-GigabitEthernet0/0/1] port-isolate enable [Switch-GigabitEthernet0/0/1] quit [Switch] interface gigabitethernet 0/0/2 [Switch-GigabitEthernet0/0/2] port link-type trunk [Switch-GigabitEthernet0/0/2] port trunk allow-pass vlan 100 [Switch-GigabitEthernet0/0/2] quit
# 配置Router的接口GE1/0/0加入VLAN101，创建接口VLANIF101并配置IP地址为10.23.101.2/24。<Huawei> system-view [Huawei] sysname Router [Router] vlan batch 101 [Router] interface gigabitethernet 1/0/0 [Router-GigabitEthernet1/0/0] port link-type trunk [Router-GigabitEthernet1/0/0] port trunk allow-pass vlan 101 [Router-GigabitEthernet1/0/0] quit [Router] interface vlanif 101 [Router-Vlanif101] ip address 10.23.101.2 24 [Router-Vlanif101] quit
- 配置AC与其它网络设备互通
![]()
如果AC直接连接AP，需要在AC直连AP的接口上配置缺省VLAN为管理VLAN100。
# 配置AC的接口GE0/0/1加入VLAN100，接口GE0/0/2加入VLAN101。<HUAWEI> system-view [HUAWEI] sysname AC [AC] vlan batch 100 101 [AC] interface gigabitethernet 0/0/1 [AC-GigabitEthernet0/0/1] port link-type trunk [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100 [AC-GigabitEthernet0/0/1] quit [AC] interface gigabitethernet 0/0/2 [AC-GigabitEthernet0/0/2] port link-type trunk [AC-GigabitEthernet0/0/2] port trunk allow-pass vlan 101 [AC-GigabitEthernet0/0/2] quit
- 配置DHCP服务器为STA和AP分配IP地址# 在AC上配置VLANIF100接口为AP提供IP地址，配置VLANIF101接口为STA提供IP地址，并配置下一跳为Router的缺省路由。
![]()
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 [AC] interface vlanif 100 [AC-Vlanif100] ip address 10.23.100.1 24 [AC-Vlanif100] dhcp select interface [AC-Vlanif100] quit [AC] interface vlanif 101 [AC-Vlanif101] ip address 10.23.101.1 24 [AC-Vlanif101] dhcp select interface [AC-Vlanif101] dhcp server excluded-ip-address 10.23.101.2 [AC-Vlanif101] quit [AC] ip route-static 0.0.0.0 0.0.0.0 10.23.101.2
- 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 default [AC-wlan-regulate-domain-default] country-code cn [AC-wlan-regulate-domain-default] quit [AC-wlan-view] ap-group name ap-group1 [AC-wlan-ap-group-ap-group1] regulatory-domain-profile default Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continue?[Y/N]:y [AC-wlan-ap-group-ap-group1] quit [AC-wlan-view] quit
# 配置AC的源接口。![]()
V200R021C00版本开始，配置CAPWAP源接口或源地址时，会检查和安全相关的配置是否已存在，包括DTLS加密的PSK、AC间DTLS加密的PSK、登录AP的用户名和密码、全局离线管理VAP的登录密码，均已存在才能成功配置，否则会提示用户先完成相关的配置。
[AC] capwap source interface vlanif 100 Set the DTLS PSK(contains 6-32 plain-text characters, or 48 or 68 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):****** Set the DTLS inter-controller PSK(contains 6-32 plain-text characters, or 48 or 68 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):****** Set the user name for FIT APs(contains 4-31 plain-text characters, which can only include letters, digits and underlines. And the first character must be a letter):admin Set the password for FIT APs(plain-text password of 8-128 characters or cipher-text password of 48-188 characters that must be a combination of at least three of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):******** Set the global temporary-management psk(contains 8-63 plain-text characters, or 48-108 cipher-text characters that must be a combination of at least two of the following: lowercase letters a to z, uppercase letters A to Z, digits, and special characters):********
# 开启CAPWAP DTLS不认证方式。（V200R021C00及之后版本）[AC] capwap dtls no-auth enable
![]()
V200R021C00版本开始，AC默认开启CAPWAP控制隧道的DTLS加密功能。开启该功能，添加AP时AP会上线失败，此时需要先开启CAPWAP DTLS不认证方式让AP上线，以便AP获取安全凭证，AP上线后应及时关闭该功能，避免未授权AP上线。
# 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60de-4476-e360，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60de-4476-e360的AP部署在1号区域，命名此AP为area_1。![]()
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为AP5030DN，具有射频0和射频1两个射频。AP5030DN的射频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 60de-4476-e360 [AC-wlan-ap-0] ap-name area_1 Warning: This operation may cause AP reset. Continue?

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] Extra information: P : insufficient power supply -------------------------------------------------------------------------------------------------- ID MAC Name Group IP Type State STA Uptime ExtraInfo -------------------------------------------------------------------------------------------------- 0 60de-4476-e360 area_1 ap-group1 10.23.100.254 AP5030DN nor 0 10S - -------------------------------------------------------------------------------------------------- Total: 1
# 关闭CAPWAP DTLS不认证方式。（V200R021C00及之后版本）[AC-wlan-view] quit [AC] undo capwap dtls no-auth enable [AC] wlan
- 配置WLAN业务参数# 创建名为“wlan-net”的安全模板，并配置安全策略。
![]()
举例中以配置WPA-WPA2+PSK+AES的安全策略为例，密码为“a1234567”，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-net [AC-wlan-sec-prof-wlan-net] security wpa-wpa2 psk pass-phrase a1234567 aes [AC-wlan-sec-prof-wlan-net] quit
# 创建名为“wlan-net”的SSID模板，并配置SSID名称为“wlan-net”。[AC-wlan-view] ssid-profile name wlan-net [AC-wlan-ssid-prof-wlan-net] ssid wlan-net [AC-wlan-ssid-prof-wlan-net] quit
# 创建名为“wlan-net”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-net [AC-wlan-vap-prof-wlan-net] forward-mode tunnel [AC-wlan-vap-prof-wlan-net] service-vlan vlan-id 101 [AC-wlan-vap-prof-wlan-net] security-profile wlan-net [AC-wlan-vap-prof-wlan-net] ssid-profile wlan-net [AC-wlan-vap-prof-wlan-net] 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-net”的配置。[AC-wlan-view] ap-group name ap-group1 [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 0 [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 1 [AC-wlan-ap-group-ap-group1] quit
- 配置AP射频的信道和功率
![]()
射频的信道和功率自动调优功能默认开启，如果不关闭此功能则会导致手动配置不生效。举例中AP射频的信道和功率仅为示例，实际配置中请根据AP的国家码和网规结果进行配置。
# 关闭AP射频0的信道和功率自动调优功能，并配置AP射频0的信道和功率。[AC-wlan-view] ap-id 0 [AC-wlan-ap-0] radio 0 [AC-wlan-radio-0/0] calibrate auto-channel-select disable [AC-wlan-radio-0/0] calibrate auto-txpower-select disable [AC-wlan-radio-0/0] channel 20mhz 6 Warning: This action may cause service interruption. Continue?[Y/N]y [AC-wlan-radio-0/0] eirp 127 [AC-wlan-radio-0/0] quit# 关闭AP射频1的信道和功率自动调优功能，并配置AP射频1的信道和功率。[AC-wlan-ap-0] radio 1 [AC-wlan-radio-0/1] calibrate auto-channel-select disable [AC-wlan-radio-0/1] calibrate auto-txpower-select disable [AC-wlan-radio-0/1] channel 20mhz 149 Warning: This action may cause service interruption. Continue?[Y/N]y [AC-wlan-radio-0/1] eirp 127 [AC-wlan-radio-0/1] quit [AC-wlan-ap-0] quit - 验证配置结果
WLAN业务配置会自动下发给AP，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 60DE-4476-E360 ON WPA/WPA2-PSK 0 wlan-net 0 area_1 1 1 60DE-4476-E370 ON WPA/WPA2-PSK 0 wlan-net ------------------------------------------------------------------------------- Total: 2
STA搜索到名为“wlan-net”的无线网络，输入密码“a1234567”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。
