QALA

• This guide walks you through the steps required for getting your Juniper data centre switches ready to be deployed with the Apstra automation solution.
• The main tasks are to install device system agents on devices, then bring those devices under Apstra control, either manually or automatically with Apstra ZTP. We’ll cover both methods.
• Once you’ve onboarded your devices, they become Managed Devices, ready to be assigned in one of the Apstra server’s blueprints.

HLOKOMELA: Pele o qala, o tlameha ho kenya le ho lokisa seva sa Apstra. Ho fumana lintlha tse ling, bona Juniper Apstra Quick Start

Apstra automates data centre networks of all sizes and complexities. Intent-based networking makes all aspects of operating data centre fabrics simpler, reliable, and efficient. A key to achieving such results is how the solution controls each individual device that comprises a managed fabric. The distributed agent architecture is an important component of what makes Apstra a unique and powerful automation solution. Let’s discuss the various elements that comprise the onboarding process.

Baemeli ba Sisteme

• Device system agents manage communication between devices and the Apstra server.
• They’re responsible for performing configuration on the devices.
• They also facilitate the transfer of device telemetry, a key component of intent-based analytics (IBA).
• For all these elements to operate smoothly, Juniper puts supported device models and NOS software through a rigorous system of testing.
• It’s imperative that you reference the Lisebelisoa tse tšoanelehang le liphetolelo tsa NOS tables when choosing hardware and software versions for your data centre fabric.
• You can install agents directly on a switch in the user space in the NOS (onbox), or you can install them in containers within the Apstra cluster (offbox) and communicate with the device that way.
• You’ll select one depending on your scenario.
• Some NOS types don’t support on-box agents. And some network operators don’t want to install agent software directly onto network devices.
• If you elect to use off-box agents, you must make considerations for cluster capacity to accommodate their location.

Sebopeho sa Sesebelisoa Stages

• For the Apstra server and managed devices to communicate, Apstra uses an out-of-band management network.
• For them to be able to communicate, the IP address, user credentials and basic configuration parameters must be in place.
• This minimal configuration state is called “pristine configuration.” Once it’s in place and the switch and server can communicate, you can install a device agent.
• Apstra then captures the existing device configuration and saves it as a baseline. See a pristine configuration example ka tlase.

• Phetoho ea Pristine ke ea pele ho tse 'maloatages that a device can be in when it’s under Apstra management.
• Devices are placed into various configurations as they are moved in and out of operation.
• To appreciate how the solution operates, it’s essential to understand these stages.

Ho tsamaea ka Apstra ZTP

• Apstra ZTP resides on its own VM, separate from the Apstra server.
• It automatically discovers new switches and those that have been reset to factory settings (zeroised)
• Use the Apstra server GUI to check the state of the ZTP server and the management of devices.
• This provides visibility into all aspects of the process, making it easy to onboard any number of devices quickly and with the desired settings and NOS versions, place.

The ZTP service provides DHCP for automatic IP addressing, installation of pristine configurations and installation of the system agents. Apstra ZTP performs these steps:

1. DHCP (ho ikhethela)
   • Sesebelisoa se kopa aterese ea IP ka DHCP.
   • Sesebelisoa se fumana aterese ea IP e abetsoeng le pointer ho setšoantšo se boletsoeng sa OS.
2. Device Initialisation
   • Sesebelisoa se khoasolla mongolo oa ZTP oo u ka o khethang ka TFTP.
   • The device executes the script, preparing it for management. The OS image is checked and is upgraded, if necessary.
   • Sesebediswa sa admin/root password se setilwe.
   • System Agent ID is initialised.
3. Agent Initialisation
   • The ZTP script leverages APIs to initiate the agent installation. It recognises automatically whether an on-box or off-box is needed.

The Apstra ZTP service is a comprehensive set of tools that you can customise in various ways to adapt to your specific requirements. Once you have downloaded the server image and performed any customisations, it’s ready to simplify bringing switches into the Apstra automation platform.
HLOKOMELA: The Apstra ZTP service requires installation and configuration to adapt to your specific environment. You can find step-by-step instructions for installing and onboarding devices see the Apstra ZTP chapter in the Juniper Apstra User Guide.
Now we’ve seen how devices are initialised. Let’s now look at how we move them into an operating network.

Holimo le ho matha

Lisebelisoa tse Laoloang

• You’ve followed the manual steps or you’ve used ZTP to get your devices installed with their management IP addresses and device agents. Plus, your switches are registered with the Apstra server. But they’re not quite ready for deployment.
• Just after being added, devices are placed into the Out-of-Service Quarantine state. To place them under full control of the system, they need to be acknowledged.

• Once you’ve acknowledged your devices, you can drill into numerous aspects of the device’s status.
• There are additional tools to show the agent state, allow us to work with the Pristine Config and to view sesebediswa telemetry.

• ZTP can initiate NOS upgrades if needed. But what do you do if you need to upgrade the software after the devices are under the control of the system? The good news is that the Managed Devices page hosts a tool that can keep your NOS versions fresh and secure.
• This is critical for the network to operate properly.
• It’s also a convenient manner to deal with any issues that may be encountered that require you to perform an update.
• The NOS management tool offers flexibility for image storage location and visibility into installation progress.
