配置流程

WLAN不同的特性和功能需要在不同类型的模板下进行配置和维护,这些模板统称为WLAN模板,如域管理模板、射频模板、VAP模板、AP系统模板、AP有线口模板、WIDS模板。当用户在配置WLAN业务功能时,需要在对应功能的WLAN模板中进行参数配置,配置完成后,须将此模板引用到AP组或AP中,配置才会自动下发到RU,进而配置的功能在RU上生效。由于模板之间是存在相互引用关系的,因此在用户配置过程中,需要提前了解各个模板之间存在的逻辑关系。模板的逻辑关系和基本配置流程请参见WLAN业务配置流程

组网需求

某小型企业为员工提供WLAN网络业务,由于场所面积不大,可以通过一台中心AP对RU进行管理。同时为了区分部门进行管理,不同部门的员工在不同的子网。企业希望员工在企业内部移动办公的同时网络业务不中断。

图1所示,中心AP为企业员工提供业务服务,中心AP分别通过Switch_1和Switch_2连接area_1和area_2。

配置思路

采用如下的思路配置中心AP内漫游:

  1. 配置网络互通,使RU与中心AP之间能够传输CAPWAP报文。
  2. 配置中心AP作为DHCP服务器,为STA和RU分配IP地址。
  3. 配置WLAN基本业务,保证用户能够连接到无线网络。

配置注意事项

建议在与RU直连的设备接口上配置端口隔离,如果不配置端口隔离,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。

操作步骤
  1. 配置Switch和中心AP,使RU和中心AP互通。

    # 在接入交换机Switch_1上创建VLAN100(管理VLAN)。Switch_1连接RU_1的接口GE0/0/1和连接中心AP的接口GE0/0/2加入VLAN100。
    <HUAWEI> system-view
    [HUAWEI] sysname Switch_1
    [Switch_1] vlan batch 100
    [Switch_1] interface gigabitethernet 0/0/1
    [Switch_1-GigabitEthernet0/0/1] port link-type trunk
    [Switch_1-GigabitEthernet0/0/1] port trunk pvid vlan 100
    [Switch_1-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
    [Switch_1-GigabitEthernet0/0/1] quit
    [Switch_1] interface gigabitethernet 0/0/2
    [Switch_1-GigabitEthernet0/0/2] port link-type trunk
    [Switch_1-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
    [Switch_1-GigabitEthernet0/0/2] quit
    # 在接入交换机Switch_2上创建VLAN100(管理VLAN)。Switch_2连接RU_2的接口GE0/0/1和连接中心AP的接口GE0/0/2加入VLAN100。
    <HUAWEI> system-view
    [HUAWEI] sysname Switch_2
    [Switch_2] vlan batch 100
    [Switch_2] interface gigabitethernet 0/0/1
    [Switch_2-GigabitEthernet0/0/1] port link-type trunk
    [Switch_2-GigabitEthernet0/0/1] port trunk pvid vlan 100
    [Switch_2-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
    [Switch_2-GigabitEthernet0/0/1] quit
    [Switch_2] interface gigabitethernet 0/0/2
    [Switch_2-GigabitEthernet0/0/2] port link-type trunk
    [Switch_2-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
    [Switch_2-GigabitEthernet0/0/2] quit
    # 配置中心AP连接Switch_1的接口GE0/0/1和连接Switch_2的接口GE0/0/2加入VLAN100。
    <HUAWEI> system-view
    [HUAWEI] sysname AP
    [AP] vlan batch 100 to 101
    [AP] interface gigabitethernet 0/0/1
    [AP-GigabitEthernet0/0/1] port link-type trunk
    [AP-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
    [AP-GigabitEthernet0/0/1] quit
    [AP] interface gigabitethernet 0/0/2
    [AP-GigabitEthernet0/0/2] port link-type trunk
    [AP-GigabitEthernet0/0/2] port trunk allow-pass vlan 100
    [AP-GigabitEthernet0/0/2] quit

  2. 配置中心AP作为DHCP服务器,为STA和RU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RU提供IP地址,VLANIF101为STA提供IP地址。
    
    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>。
    [AP] dhcp enable
    [AP] interface vlanif 100
    [AP-Vlanif100] ip address 10.23.100.1 255.255.255.0
    [AP-Vlanif100] dhcp select interface
    [AP-Vlanif100] quit
    [AP] interface vlanif 101
    [AP-Vlanif101] ip address 10.23.101.1 255.255.255.0
    [AP-Vlanif101] dhcp select interface
    [AP-Vlanif101] quit

  3. 配置RU上线

    # 创建AP组“ap-group1”。
    
    [AP] wlan
    [AP-wlan-view] ap-group name ap-group1
    [AP-wlan-ap-group-ap-group1] quit
    # 创建域管理模板,在域管理模板下配置中心AP的国家码并在AP组下引用域管理模板。
    
    [AP-wlan-view] regulatory-domain-profile name domain
    [AP-wlan-regulatory-domain-domain] country-code cn
    [AP-wlan-regulatory-domain-domain] quit
    [AP-wlan-view] ap-group name ap-group1
    [AP-wlan-ap-group-ap-group1] regulatory-domain-profile domain
    Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continu e?[Y/N]:y  
    [AP-wlan-ap-group-ap-group1] quit
    # 配置中心AP上RU的管理VLAN。
     
    [AP] management-vlan 100
    # 在中心AP上离线导入RU,并将RU加入AP组“ap-group1”中。假设RU的MAC地址为60de-4476-e360,并且根据RU的部署位置为RU配置名称,便于从名称上就能够了解RU的部署位置。例如MAC地址为60de-4476-e360的RU部署在1号区域,命名此RU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RU为R240D,具有射频0和射频1两个射频。R240D的射频0为2.4GHz射频,射频1为5GHz射频。
    
    [AP] wlan
    [AP-wlan-view] ap auth-mode mac-auth
    [AP-wlan-view] ap-id 1 ap-mac 60de-4476-e360
    [AP-wlan-ap-1] ap-name area_1
    Warning: This operation may cause AP reset. Continue? [Y/N]:y  
    [AP-wlan-ap-1] 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

    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  
    [AP-wlan-ap-2] quit
    # 将RU上电后,当执行命令display ap all查看到RU的“State”字段为“nor”时,表示RU正常上线。
    
    [AP-wlan-view] display ap all
    Total AP information:
    nor  : normal          [2]
    ExtraInfo : Extra information

    ----------------------------------------------------------------------------------------------------------
    Total: 2

  4. 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。
    举例中以配置WPA2+PSK+AES的安全策略为例,密码为a1234567,实际配置时请根据实际情况,配置符合实际要求的安全策略。
    
    [AP-wlan-view] security-profile name wlan-security
    [AP-wlan-sec-prof-wlan-security] security wpa2 psk pass-phrase a1234567 aes
    [AP-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”。
    
    [AP-wlan-view] ssid-profile name wlan-ssid
    [AP-wlan-ssid-prof-wlan-ssid] ssid wlan-net
    Warning: This action may cause service interruption. Continue?[Y/N]y 
    [AP-wlan-ssid-prof-wlan-ssid] quit
    # 创建名为“wlan-vap1”的VAP模板,配置业务VLAN,并引用安全模板“wlan-security”和SSID模板“wlan-ssid”。
    
    [AP-wlan-view] vap-profile name wlan-vap1
    [AP-wlan-vap-prof-wlan-vap1] service-vlan vlan-id 101
    [AP-wlan-vap-prof-wlan-vap1] security-profile wlan-security
    [AP-wlan-vap-prof-wlan-vap1] ssid-profile wlan-ssid
    [AP-wlan-vap-prof-wlan-vap1] quit
    # 配置AP组引用VAP模板,RU上射频0和射频1都使用VAP模板“wlan-vap”的配置。
    
    [AP-wlan-view] ap-group name ap-group1
    [AP-wlan-ap-group-ap-group1] vap-profile wlan-vap1 wlan 1 radio 0
    [AP-wlan-ap-group-ap-group1] vap-profile wlan-vap1 wlan 1 radio 1
    [AP-wlan-ap-group-ap-group1] quit

  5. 配置RU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RU射频的信道和功率仅为示例,实际配置中请根据RU的国家码和网规结果进行配置。
    
    # 关闭RU射频0的信道和功率自动调优功能,并配置RU射频0的信道和功率。
    [AP-wlan-view] ap-id 1
    [AP-wlan-ap-1] radio 0
    [AP-wlan-radio-1/0] calibrate auto-channel-select disable
    [AP-wlan-radio-1/0] calibrate auto-txpower-select disable
    [AP-wlan-radio-1/0] channel 20mhz 6
    Warning: This action may cause service interruption. Continue?[Y/N]y 
    [AP-wlan-radio-1/0] eirp 127
    [AP-wlan-radio-1/0] quit
    # 关闭RU射频1的信道和功率自动调优功能,并配置RU射频1的信道和功率。
    [AP-wlan-ap-1] radio 1
    [AP-wlan-radio-1/1] calibrate auto-channel-select disable
    [AP-wlan-radio-1/1] calibrate auto-txpower-select disable
    [AP-wlan-radio-1/1] channel 20mhz 149
    Warning: This action may cause service interruption. Continue?[Y/N]y 
    [AP-wlan-radio-1/1] eirp 127
    [AP-wlan-radio-1/1] quit
    [AP-wlan-ap-1] quit

  6. 验证配置结果

    WLAN业务配置会自动下发给RU,配置完成后,执行命令display vap ssid wlan-net查看VAP信息,当“Status”显示为“ON”时,表示RU对应射频上的VAP已创建成功。
    [AP-wlan-view] display vap ssid wlan-net
    WID : WLAN ID

    ---------------------------------------------------------------------------------------
    Total: 2
    STA在RU_1的覆盖范围内搜索到SSID为“wlan-net”的无线网络,输入密码“a1234567”并正常关联后,在中心AP上执行命令display station ssid wlan-net,查看STA的接入信息,可以看到STA关联到了RU_1,STA的MAC地址为“e019-1dc7-1e08”。
