Install NVIDIA DOCA and configure SuperNIC functionality: Worked Example — NVIDIA Spectrum Networking (NVIDIA-Certified Professional: AI Networking)

Installing NVIDIA DOCA and Configuring SuperNIC Functionality: A Worked Example

This worked example guides you through the step-by-step process of installing NVIDIA DOCA and configuring SuperNIC functionality within an NVIDIA Spectrum Networking environment. This task is essential for leveraging advanced programmable networking capabilities in AI workloads, a key component of the NVIDIA-Certified Professional: AI Networking exam.

Scenario

Your organization has deployed NVIDIA Spectrum switches and SuperNIC-enabled network interface cards (NICs) to accelerate AI data center networking. You need to install the NVIDIA DOCA software development kit (SDK) on the host server and configure the SuperNIC to offload networking and security functions, improving performance and efficiency.

Step 1: Prepare the Host Environment

• Ensure the host server runs a supported Linux distribution (e.g., Ubuntu 20.04 or CentOS 8).
• Verify that the SuperNIC hardware is installed and recognized by the operating system using lspci | grep NVIDIA.
• Update the system packages and install prerequisites such as gcc, make, and kernel-devel.

Step 2: Download and Install NVIDIA DOCA SDK

• Access the NVIDIA DOCA SDK download portal and obtain the latest stable release compatible with your SuperNIC model.
• Transfer the DOCA SDK package to the host server.
• Extract the package:tar -xvf doca-sdk-version.tar.gz
• Navigate to the extracted directory and run the installation script:sudo ./install.sh
• Follow on-screen prompts to complete the installation.

Step 3: Verify DOCA Installation

• Check that DOCA tools are accessible:doca --version
• Confirm the SuperNIC device is detected by DOCA:doca device list

Step 4: Configure SuperNIC Functionality

• Identify the networking functions to offload, such as packet filtering, encryption, or telemetry.
• Use DOCA CLI or APIs to enable these features. For example, to enable packet filtering:doca filter enable --device DEVICE_ID
• Configure security policies or QoS parameters as required by your AI networking workload.
• Apply the configuration and verify status:doca filter status --device DEVICE_ID

Step 5: Test and Validate

• Run sample DOCA applications included in the SDK to test SuperNIC offload capabilities.
• Monitor network performance and latency improvements using tools like iperf3 and NVIDIA NetQ.
• Check system logs for errors or warnings related to DOCA or SuperNIC.

Worked Example Summary

Problem: Install NVIDIA DOCA SDK on a Linux host and configure SuperNIC to enable packet filtering offload.

Solution:

1. Verified SuperNIC hardware presence with lspci.
2. Downloaded and installed DOCA SDK using install.sh.
3. Confirmed installation with doca --version and device detection.
4. Enabled packet filtering offload via doca filter enable --device DEVICE_ID.
5. Validated functionality with doca filter status and performance testing.

This process ensures the SuperNIC is correctly configured to accelerate AI networking workloads by offloading critical functions, reducing CPU load, and improving throughput.
