ZTP+ Device Configuration

Using Extreme Networks' ZTP+ (Zero Touch Provisioning Plus) functionality, you can quickly add new ZTP+-enabled devices to your network and configure them in ExtremeCloud IQ Site Engine.

Typically, when adding a new device to the network, a network administrator connects a console cable to the device to access the local console and manually configure the device.

  IMPORTANT: Stacked ExtremeXOS/Switch Engine systems must be running ExtremeXOS/Switch Engine version 30.3 or later to support ZTP+ configuration.

In ExtremeCloud IQ Site Engine, new devices are automatically discovered on the network the moment they are connected. ZTP+-enabled devices send information to ExtremeCloud IQ Site Engine automatically, including the serial number, the number and speed of the ports, and the firmware version. When a ZTP+-enabled device is connected, you can add it to ExtremeCloud IQ Site Engine with minimal server configuration. In addition, the latest updates are automatically downloaded to the new device. This process minimizes the amount of time needed to configure a new device and deploy it on the network.

Prerequisites

Before connecting your devices, configure the following:

Select the Reference Firmware Image Location

You can configure ExtremeCloud IQ Site Engine to automatically update your device's firmware and application versions. When upgrading the firmware image on your device, access the appropriate firmware image for your version from ExtremeNetworks.com and save it on your server to a directory you configure in ExtremeCloud IQ Site Engine. After the firmware image is saved on the ExtremeCloud IQ Site Engine server, it is available in ExtremeCloud IQ Site Engine and can be downloaded to the device.

For the device to recognize a new version is available, the firmware image must be downloaded from ExtremeNetworks.com to your server and saved in a directory you configure in ExtremeCloud IQ Site Engine.

To configure the file transfer directory:

  1. Access the Options tab.
  2. Select Inventory Manager in the left panel.
  3. Enter the Firmware Directory Path in either the FTP Server Properties, SCP Server Properties, or TFTP Properties section of the right panel, depending on the file transfer settings used.
  4. Download the latest firmware image for your device from ExtremeNetworks.com and save it in the specified directory.

When you download the firmware image from ExtremeNetworks.com and save it on the ExtremeCloud IQ Site Engine server, use the Firmware tab in ExtremeCloud IQ Site Engine to download the image from the ExtremeCloud IQ Site Engine server to the device.

  1. Access the Network > Firmware tab.
  2. Expand the Device Type navigation tree in the left-panel for the device family you are configuring and select the folder for the type of device.
  3. Right-click the firmware file you downloaded (specified in the section above) and select Set as Reference Image.

  4. Your device automatically updates with this firmware image when it restarts and is logged in the Event log with a Category of Inventory.

Default Device Configuration in ExtremeCloud IQ Site Engine

Before connecting your devices, you can configure the default settings that ExtremeCloud IQ Site Engine applies to all devices you add to the network. This is accomplished using the Site tab.

  1. Access the Devices tab in ExtremeCloud IQ Site Engine.
  2. Expand the World Site navigation tree and select the map in the left panel into which you are adding the devices.
  3. Select the Site tab in the right panel.
  4. Select the Automatically Add Devices checkbox in the Discovered Device Actions section and any other actions you want to occur on your devices discovered in ExtremeCloud IQ Site Engine.
    G


  5. Use the Custom Configuration section to automatically run a script on devices being added to the site, if necessary.

    CAUTION:If the script or workflow task selected for the Custom Configuration restarts the device, other actions selected to execute during discovery might not execute (for example, Add Trap Receiver).
  6. Select Add Device to Policy Domain or Add Device to ExtremeControl Engine Group to automatically add devices being added to the site to a Policy Domain or ExtremeControl engine group.
  7. Add the VLANs that are used on your devices on the VLAN Definition tab by selecting the Add button and entering the Name and VID.
  8. Use the Port Templates tab to create a port configuration, if necessary.
  9. Enter the Gateway Address, Domain Name, and DNS Server address on the ZTP+ Device Defaults tab. Additionally, you can configure the NTP Server address and select the protocols to enable on your devices, if necessary.
  10. Select Save.

    The default configuration for this site is complete and any devices you discover with this site selected use this criteria.

Download XMODs (ExtremeXOS/Switch Engine devices only)

XMODs are files that work in conjunction with firmware image upgrades to enhance ZTP+ functionality on ExtremeXOS/Switch Engine devices as well as provide bug fixes for existing features. Like firmware image upgrades, they are posted by Extreme Networks on github and ExtremeNetworks.com. Save XMODs in the directory you specify in the Firmware Directory Path field. Do not set an XMOD as the reference image.

  IMPORTANT: ExtremeXOS devices running version 21.1.1.4 require an update to the CloudConnector XMOD for ZTP+ to function properly. Save the most recent XMOD in the Firmware Directory Path specified above to update the device, allowing ZTP+ to function as intended. Recent ExtremeXOS/Switch Engine firmware images already include the CloudConnector XMOD, and no updates are required for ZTP+ functionality.

If multiple CloudConnector XMOD files exist in the same directory on the ExtremeCloud IQ Site Engine server as the reference image, ExtremeCloud IQ Site Engine downloads the XMOD file with the higher version number on the device.

General Network Configuration

In order for the switch to communicate to the ExtremeCloud IQ Site Engine server:

  • The DHCP Server needs to return a DNS Server and Domain Name to the ZTP+ device.
  • The DNS Server needs to map the name extremecontrol.<domain-name> to the IP address of the ExtremeCloud IQ Site Engine server.

NOS Persona Change from Switch Engine to Fabric Engine

You can configure the ExtremeCloud IQ Site Engine to change the persona of a switch from Switch Engine to Fabric Engine during the ZTP+ process. For the persona change to occur, you must:

  • Upload the Fabric Engine firmware to both the TFTP and SFTP directories (Network > Firmware > Upload...)
  • Configure the Fabric Engine firmware in the SFTP directory as a reference image
  • Configure the NOS Persona Change field as To Fabric Engine for a specific site, or manually during the ZTP+ process

Adding the Device to the ExtremeCloud IQ Site Engine Database

Now that the default criteria is configured for devices added to the World Site and you set up the DHCP and DNS servers allowing the device to communicate with the ExtremeCloud IQ Site Engine database, connect the device and add it to ExtremeCloud IQ Site Engine.
