将交换机载入 Mist 云
如果您的交换机已载入 Mist 云，请忽略本主题中的步骤。
要通过瞻博网络 Mist 云配置和管理交换机，必须确保交换机已添加到 Mist 云中。要查看 Mist 支持的交换机型号，请访问 瞻博网络 Mist 支持的硬件。
您可以将绿地或棕地交换机添加到 Mist 云。
在这种情况下，绿地交换机是新的云就绪交换机，而棕地交换机是从之前的部署引入瞻博网络 Mist 云架构的交换机。
交换机上线先决条件
载入交换机之前：
-
确保您拥有瞻博网络 Mist Wired Assurance 订阅和瞻博网络 Mist 门户的登录凭据。要开始使用 Mist，请按照 快速入门：Mist 中的说明进行操作。
-
确保交换机已连接到 DNS 服务器（也建议使用 NTP 服务器），并且能够通过互联网连接到瞻博网络 Mist 云架构。
-
如果云和交换机之间存在防火墙，请允许 TCP 端口 2200 对交换机管理端口进行出站访问。
载入绿地交换机
您可以通过 Mist AI 移动应用程序将单个绿地云就绪交换机上线到 Mist 云。但是，如果您想同时载入多台云就绪交换机，可以通过瞻博网络 Mist 门户，使用与采购订单关联的激活码来实现。
要载入绿地交换机，请按照 快速入门：使用 Mist 的云就绪 EX 和 QFX 交换机中的说明进行操作。

Onboarding a Greenfield CloudReady EX switch is simple. In your inventory page, find the Switches tab. Click on Claim Switches.
Type in your switch's unique claim code, which can be found near the QR code at the front of the switch. Alternatively, you can also enter an activation code, which pulls all your newly purchased Juniper hardware from one order, rather than adding individual switch codes. Add and check for your desired settings, such as site assignment and configuration management.
Click Claim, and the switch has been added to the site. The EX3400 has been added. In the site view, you should see the switch appropriately assigned.
Notice that red indicates the switch is offline, but will turn green once it comes online. The switch is cloud-managed and accounted for as part of the health metrics above.
载入棕地交换机
在激活棕地交换机之前，请务必备份交换机上的现有 Junos OS 配置，因为当采用交换机从瞻博网络 Mist 云进行管理时，旧配置将被替换。通过运行 request system configuration rescue save 命令备份现有 Junos OS 配置，该命令将保存当前活动的配置和任何特定于安装的参数。
在此过程中，您将对瞻博网络 Mist 门户进行一些配置更改，并使用 Junos OS CLI 对交换机进行一些配置更改。确保您可以登录到两个系统。
要将棕地交换机载入 Mist 云，请执行以下操作：
- 选择页面顶部的“交换机”，然后单击右上角的“采用交换机”按钮以生成互操作性所需的 Junos OS CLI 命令。这些命令创建一个瞻博网络 Mist 用户帐户，并通过 TCP 端口 2200 连接到瞻博网络 Mist 云（交换机连接来自管理接口，用于配置设置和发送遥测数据）。

Adopting switches for brownfield environments only takes a few steps. In Organization, look for the Inventory tab and toggle to Switches. Click on Adopt Switches.
This brings up a clipboard of CLI commands to copy and paste into the console of a switch. Put in the config and commit it in the switch. Ensure that TCP port 2200 is open to the internet.
This allows for the switch to communicate with the Juniper Mist cloud. Check that it is connected properly by entering Show System Connection to see an established TCP session. Going back to the dashboard, you can see the EX switch online and fully cloud-managed.
Templates will also be inherited when you enable Configuration Management. Don't forget to save. Now you're good to go.
Adopting an EX switch to the Juniper Mist cloud from a brownfield environment is a straightforward process. Now you have the power and simplicity of a cloud-managed solution for your EX switches.
