配置基于 MAC 的身份验证和 MAC 身份验证旁路 (MAB)

请按照以下步骤配置有线设备,以根据设备的 MAC 地址对设备进行身份验证。

您可以将 MAC 身份验证与基于证书或基于证书的身份验证一起使用,作为额外的安全层。

瞻博网络 Mist Access Assurance 支持 MAC 身份验证旁路 (MAB),可跨有线和无线网络实现统一访问控制。本主题提供为有线设备配置 MAB 的示例。

除了基于证书的 EAP-TLS 身份验证外,此示例还说明如何为有线设备创建 MAC 身份验证。该任务还包括为不支持 dot 1x 的有线端设备(如 Phillips 集线器)创建身份验证策略的步骤。

先决条件

为有线设备配置基于 MAC 的身份验证

观看以下视频,了解如何为有线设备配置和验证基于 MAC 的身份验证:

Well, what about wired devices? How do we authenticate an authorized wired client? Well, it turns out we could do it right here in the same place. So we could create a couple of more rules. So we can say OK, if we look at wired devices that are using certificates to authenticate , we could just call this rule wired certificate authentication. We can effectively apply the same matching criteria as for wireless. There's no difference whatsoever here.

On the right-hand side, we'll decide where we want to move these devices after authentication and the right policy match. And finally, what about non-.1x capable devices on the wired side? So for example, I have here a Phillips hub that does not support .1x. How can I authenticate a Phillips app? So I could create a label for the Phillips device. The label will be client list. And I'll just say approved Phillips app. And I'll just put the MAC address of that device in. Oh. And you could put a list of MAC addresses. You can put the list of Mac OUIs. And remember that all of these labels that I'm creating in the UI - they're all available through the REST API. So there is always an endless possibility of integration with existing, say, inventory management systems that can just put all the new device MAC addresses in those lists for authentication and authorization.

So we'll just click Create. Create this label. And we'll create a rule. We'll call it approved Phillips devices. And here we are matching on wired devices that are doing MAC address authentication bypass that are part of this client list label. And in this case, we will move them to - well, I don't want to move them to Corp VLAN. That's not what I want. I will create an IoT VLAN. And in our case, that's going to be VLAN 3000. And I'm going to add this to an IoT VLAN. And now, we have our authentication policies configuration done.

OK, so how do we validate, right? So we've connected a couple of clients to the switch. One is a laptop that's doing .1x using certificate. Another one is the Phillips Hue app. That doesn't do any .1x, and just doing MAC authentication. So we could see those two clients are connected.

Let's take a look at the laptop one. So we could click on the port. We see that there is a client with a username flashing up. Let's take a look at the wired client insights. And what we can see here is that the user has been authenticated. You could see the port up and down events from the switch side. We see all the authentication phases, same as we saw in the wireless side. The client trusts the server. The server trusts the client certificate. We get all the metadata here. We then are saying client access is allowed. And voila. We matched the same authentication policy rule. Great. So now, we know that this part is working.

Now, we go to switch back. And let's look at the Philips device. That device is not doing any form of .1x authentication. So let's just take a look at the wired client insights. Yeah, and we are seeing that here the user is authenticated. And there is a client access allowed event here as well. And in this case, the authentication type is Mac address bypass - the MAC address that we've added to the client list. And voila. We are matching the right approved Phillips device rule.

使用以下步骤在使用瞻博网络 Mist 门户的网络中设置基于 MAC 的身份验证:

  1. 创建身份验证策略。
    1. 从 瞻博网络 Mist 门户的左侧菜单中,选择组织>访问>身份验证策略
      创建新规则以向具有有效证书的客户端提供访问权限。请参阅 配置认证策略
      图 1:为有线客户端 Create Auth Policy for Wired Client创建身份验证策略
      使用以下详细信息定义身份验证策略:
      1. 名称 — 输入策略的名称(例如:有线证书身份验证)
      2. 匹配标准 — 选择 EAP-TLS有线。
      3. 策略 - 选择 允许
      4. 策略操作 — 允许网络访问
      5. 分配的 VLAN — 公司 VLAN
  2. 要为 LAN 端的非 dot1.x 设备提供身份验证,请创建新的策略标签。
    1. 在“身份验证策略”页面上,选择“创建标签”并输入详细信息。
      图 2:非 Dot1x 设备的 Label for Non-Dot1x device标签
      在相应字段中输入以下信息:
      1. 标注名称 - 输入标注名称(例如:Approved Phillips Hubs)
      2. 标签类型 - 选择类型客户端列表
      3. 标签值 — 输入设备的 MAC 地址
  3. 创建新的身份验证策略。
    1. 单击“添加规则”以创建新规则。
      在此规则中,使用您在上一步中为非 dot1x 设备创建的标签。
      图 3:非 Dot1X 设备的 Authentication Policy for Non-Dot1X devices身份验证策略
      在相应字段中输入以下信息:
      1. 名称 - 输入 名称。示例:经批准的菲利普斯设备。
      2. 匹配标准 — 选择 已批准的 Phillips HubsMAB(MAC 身份验证旁路)有线
      3. 策略 - 选择 允许
      4. 策略操作 - 选择允许网络访问。
      5. 分配的策略 — 选择 IoT VLAN
      现在,您已经创建了一个用于对非 dot1X 设备进行身份验证的策略。
  4. 配置交换机以执行身份验证。
    1. 从 瞻博网络 Mist 门户的左侧菜单中,选择组织>有线>交换机模板
    2. 在 Switch Templates 页面上,单击现有模板以打开其配置页面,或单击页面右上角的 Create Template 以创建模板。
    3. 在“身份验证服务器”部分中,选择“Mist 身份验证”作为身份验证服务器。
    4. 向下滚动到端口配置文件部分并输入详细信息。
      图 4:端口配置文件选项 Port Profile Options
      输入所需信息或在以下字段中选择所需选项:
      1. 名称 - 输入名称(例如: secure-port)。
      2. 模式 - 选择访问。
      3. 启用使用 dot1x 身份验证使用 MAC 身份验证 选项。如果客户端设备支持 802.1X,则交换机端口将执行 802.1X 身份验证。如果客户端设备不支持 802.1X,交换机端口将执行 MAC 身份验证。
      4. STP 边缘 - 选择 以将端口配置为生成树协议 (STP) 边缘端口。此设置可确保将端口视为边缘端口。

      此示例对其余字段使用默认值。

    5. 交换机上连接的有线客户端需要访问网络的每个端口分配一个端口配置文件。

      在“选择交换机配置”部分的端口配置选项卡上,单击 “添加端口范围 ”,将端口配置文件与端口相关联。

      图 5:将端口配置文件分配给交换机 Assign Port Profile to Port Ranges on a Switch上的端口范围

      输入端口 ID 并选择您在上一步中创建的配置文件。

    6. 点击保存
