业务需求

企业用户接入WLAN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。

AP位于企业分部,AC位于企业总部,管理员希望所有AP均由AC统一管理,且希望对分支和总部之间相互访问的流量进行安全保护,因此在分支网关和总部网关之间建立一个IPSec隧道来实施安全保护。

组网需求
  • AC组网方式:AC位于企业总部,AP位于企业分支,在AC和AP间配置IPSec隧道。
  • DHCP部署方式:Router_1作为DHCP服务器为STA和AP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IPSec用于建立IPSec隧道。

    1. 配置接口的IP地址和到对端的静态路由,保证两端路由可达。

    2. 配置ACL,以定义需要IPSec保护的数据流。

    3. 配置IPSec安全提议,定义IPSec的保护方法。

    4. 配置IKE对等体,定义对等体间IKE协商时的属性。

    5. 配置安全策略,并引用ACL、IPSec安全提议和IKE对等体,确定对何种数据流采取何种保护方法。

    6. 在接口上应用安全策略组,使接口具有IPSec的保护功能。

  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。

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。

  • 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Switch的GE0/0/1、GE0/0/2加入VLAN100、VLAN101,GE0/0/1的缺省VLAN为VLAN100。

    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>。
  4. 配置ACL,定义需要IPSec隧道保护的数据流

  6. 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。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912351_b1451837292190921">wlan</strong>

    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。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC-wlan-view] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912351_b1815954045190921">regulatory-domain-profile name default</strong>

    配置AC的源接口。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912370_b2076192014190921">capwap source interface vlanif 200</strong></span></span></span>

    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。

    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。

  7. 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。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC-wlan-view] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912351_b1991067776190921">security-profile name wlan-net</strong>

    创建名为"wlan-net"的SSID模板,并配置SSID名称为"wlan-net"。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC-wlan-view] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912351_b69022931190921">ssid-profile name wlan-net</strong>

    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。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC-wlan-view] <strong>vap-profile name wlan-net</strong>

    [AC-wlan-net-prof-wlan-net] <strong>ssid-profile wlan-net</strong>
    [AC-wlan-net-prof-wlan-net] <strong>quit</strong></span></span></span>

    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。

    javascript 复制代码
    <span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#dddddd">[AC-wlan-view] <strong id="ZH-CN_TASK_0176912374__zh-cn_task_0176912351_b2051092768190921">ap-group name ap-group1</strong>

  8. 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。

  9. 检查配置结果

    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。

    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。

    配置成功后,在AC执行ping 操作仍然可以ping通AP,它们之间的数据传输将被加密,执行命令display ipsec statistics可以查看数据包的统计信息。

    在Router_2上执行display ike sa操作,结果如下。
