Tutorial: Configure network for Azure Stack Edge Mini R

  • Grein

This tutorial describes how to configure network for your Azure Stack Edge Mini R device with an onboard GPU by using the local web UI.

The connection process can take about 20 minutes to complete.

Note

On Azure Stack Edge 2309 and later, Wi-Fi functionality for Azure Stack Edge Mini R has been deprecated. Wi-Fi is no longer supported on the Azure Stack Edge Mini R device.

In this tutorial, you learn about:

  • Prerequisites
  • Configure network
  • Enable compute network
  • Configure web proxy

Prerequisites

Before you configure and set up your Azure Stack Edge Mini R device, make sure that:

Configure network

Your Get started page displays the various settings that are required to configure and register the physical device with the Azure Stack Edge service.

Follow these steps to configure the network for your device.

  1. In the local web UI of your device, go to the Get started page.

  2. If a zero day update is needed, you can do that here by configuring a data port with a wired connection. For more instructions on how to set up a wired connection for this device, see Cable your device. After the update is over, you can remove the wired connection.

  3. Create certificates for Wi-Fi and signing chain. Both the signing chain and the Wi-Fi certificates must be DER format with a .cer file extension. For instructions, see Create certificates. This step is optional if you're using a Wi-Fi profile instead of certificates for authentication.

    Note

    If you're using password-based authentication on your personal Wi-Fi network, you can skip the certificate steps. Just configure the Wi-Fi port and then upload your Wi-Fi profile.

    To find out about Wi-Fi profiles for a WPA2 - Personal network and learn how to export your Wi-Fi profile, see Use Wi-Fi profiles.

  4. Add the certificates to your device:

    1. In the local web UI, go to Get started. On the Security tile, select Certificates and then select Configure.

      Local web UI "Certificates" page

    2. Select + Add certificate.

      Local web UI "Certificates" page 1

    3. Upload the signing chain and select Apply.

      Local web UI "Certificates" page 2

    4. Repeat the procedure with the Wi-Fi certificate.

      Local web UI "Certificates" page 3

    5. The new certificates should be displayed on the Certificates page.

      Local web UI "Certificates" page 4

    6. Go back to Get started.

  5. Configure the Wi-Fi port. On the Network tile, select Configure.

    On your physical device, there are five network interfaces. PORT 1 and PORT 2 are 1-Gbps network interfaces. PORT 3 and PORT 4 are all 10-Gbps network interfaces. The fifth port is the Wi-Fi port.

    Local web UI "Network settings" page 1

    Select the Wi-Fi port and configure the port settings.

    Important

    We strongly recommend that you configure a static IP address for the Wi-Fi port.

    Local web UI "Network settings" page 2

    The Network page updates after you apply the Wi-Fi port settings.

    Local web UI "Network settings" page 3

  6. Select Add Wi-Fi profile and upload your Wi-Fi profile.

    Local web UI "Port WiFi Network settings" 1

    A wireless network profile contains the SSID (network name), password key, and security information to be able to connect to a wireless network. You can get the Wi-Fi profile for your environment from your network administrator.

    Local web UI "Port WiFi Network settings" 2

    After the profile is added, the list of Wi-Fi profiles updates to reflect the new profile. The profile should show the Connection status as Disconnected.

    Local web UI "Port WiFi Network settings" 3

  7. After the wireless network profile is successfully loaded, connect to this profile. Select Connect to Wi-Fi profile.

    Local web UI "Port Wi-Fi Network settings" 4

  8. Select the Wi-Fi profile that you added in the previous step, and select Apply.

    Local web UI "Port Wi-Fi Network settings" 5

    The Connection status should update to Connected. The signal strength updates to indicate the quality of the signal.

    Local web UI "Port Wi-Fi Network settings" 6

    Note

    To transfer large amounts of data, we recommend that you use a wired connection instead of the wireless network.

  9. Disconnect PORT 1 on the device from the laptop.

  10. As you configure the network settings, keep in mind:

    • If DHCP is enabled in your environment, network interfaces are automatically configured. An IP address, subnet, gateway, and DNS are automatically assigned.
    • If DHCP isn't enabled, you can assign static IPs if needed.
    • You can configure your network interface as IPv4.
    • Network Interface Card (NIC) Teaming or link aggregation is not supported with Azure Stack Edge.
    • Serial number for any port corresponds to the node serial number. For a K-series device, only one serial number is displayed.

    Note

    • We recommend that you do not switch the local IP address of the network interface from static to DCHP, unless you have another IP address to connect to the device. If using one network interface and you switch to DHCP, there would be no way to determine the DHCP address. If you want to change to a DHCP address, wait until after the device has registered with the service, and then change. You can then view the IPs of all the adapters in the Device properties in the Azure portal for your service.
    • If you need to connect to your device from an outside network, see Enable device access from outside network for additional network settings.

After you have configured and applied the network settings, select Next: Compute to configure compute network.

Enable compute network

Follow these steps to enable compute and configure compute network.

  1. In the Compute page, select a network interface that you want to enable for compute.

    Compute page in local UI 2

  2. In the Network settings dialog, select Enable. When you enable compute, a virtual switch is created on your device on that network interface. The virtual switch is used for the compute infrastructure on the device.

  3. Assign Kubernetes node IPs. These static IP addresses are for the compute VM.

    For an n-node device, a contiguous range of a minimum of n+1 IPv4 addresses (or more) are provided for the compute VM using the start and end IP addresses. Given Azure Stack Edge is a 1-node device, a minimum of 2 contiguous IPv4 addresses are provided.

    Important

    Kubernetes on Azure Stack Edge uses 172.27.0.0/16 subnet for pod and 172.28.0.0/16 subnet for service. Make sure that these are not in use in your network. If these subnets are already in use in your network, you can change these subnets by running the Set-HcsKubeClusterNetworkInfo cmdlet from the PowerShell interface of the device. For more information, see Change Kubernetes pod and service subnets.

  4. Assign Kubernetes external service IPs. These are also the load-balancing IP addresses. These contiguous IP addresses are for services that you want to expose outside the Kubernetes cluster and you specify the static IP range depending on the number of services exposed.

    Important

    We strongly recommend that you specify a minimum of 1 IP address for Azure Stack Edge Mini R Hub service to access compute modules. You can then optionally specify additional IP addresses for other services/IoT Edge modules (1 per service/module) that need to be accessed from outside the cluster. The service IP addresses can be updated later.

  5. Select Apply.

  6. The configuration takes a couple minutes to apply and you may need to refresh the browser. You can see that the specified port is enabled for compute.

    Select Next: Web proxy to configure web proxy.

Configure web proxy

This is an optional configuration.

Important

Proxy-auto config (PAC) files are not supported. A PAC file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL. Proxies that try to intercept and read all the traffic (then re-sign everything with their own certification) aren't compatible since the proxy's certificate is not trusted. Typically transparent proxies work well with Azure Stack Edge Mini R. Non-transparent web proxies are not supported.

  1. On the Web proxy settings page, take the following steps:

    1. In the Web proxy URL box, enter the URL in this format: http://host-IP address or FQDN:Port number. HTTPS URLs are not supported.

    2. To validate and apply the configured web proxy settings, select Apply.

    Local web UI "Web proxy settings" page

  2. After the settings are applied, select Next: Device.
