How to Format Point-to-Point (P2P)#

This guide describes how to format Point-to-Point (P2P) Ethernet configuration files for use with the netautogen tool in network deployment. The process involves converting Excel files created by the NVIDIA Infrastructure Services (NVIS) Cabling Team into properly formatted .csv files that can be consumed by automated network configuration tools.

You can use one of the following formatting options:

  • Manual: You manually convert the Excel file to a .csv file.

  • Automated: You use the Network Dashboard tool for internal NVIDIA teams to format the Excel file.

The following formatted files are required:

  • p2p_ethernet.csv: This file is the formatted .csv file that can be consumed by the netautogen tool. To obtain or create this file, follow the steps below:

    1. Original Excel file is created by NVIS Cabling Team.

    2. Based on the project requirements, a file is created and modified by the team. The following Steps 1 and 2 must be completed to generate the Excel file.

    3. Here is the workflow:
