业务需求

企业用户通过WLAN接入网络,以满足移动办公的最基本需求。且在覆盖区域内移动发生漫游时,不影响用户的业务使用。

组网需求

  • AC组网方式:直连二层组网。
  • DHCP部署方式:AC作为DHCP服务器为AP和STA分配IP地址。
  • 业务数据转发方式:直接转发。

配置思路

  1. 配置AP、AC和周边网络设备之间实现网络互通。
  2. 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。
  1. 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。
  • 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。
  • 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。
  • 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(capwap dtls no-auth enable)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(undo capwap dtls no-auth enable),避免未授权AP上线。

操作步骤

  1. 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和VLAN101,GE0/0/1的缺省VLAN为VLAN100。
<HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] vlan batch 100 101
[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 100 101
[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 100 101
[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
  1. 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和VLAN101,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 100 101
[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
  1. 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
  1. 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-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。

# 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
  1. 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 direct-forward
[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
  1. 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
  1. 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

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。
