Summary

The purpose of the VPP configuration utility is to allow the user to configure VPP in a simple and safe manner. The utility takes input from the user and then modifies the key configuration files. The user can then examine these files to be sure they are correct and then actually apply the configuration. The utility also includes an installation utility and some basic tests. This utility is currently released with release 17.10.

Use

The installation and executing of the VPP configuration utility is simple. First install the python pip module. Using pip install, then pip install vpp-config. Then simply type vpp-config and answer the questions. If you are not sure what to answer choose the default. For yes or no questions the capital letter designates the default. For example, for a question that shows [Y/n] Y is the default. For numbers the default is within the brackets for example for a question that shows [1024]. 1024 is the default.

Welcome to the VPP system configuration utility

These are the files we will modify:
    /etc/vpp/startup.conf
    /etc/sysctl.d/80-vpp.conf
    /etc/default/grub

Before we change them, we'll create working copies in /usr/local/vpp/vpp-config/dryrun
Please inspect them carefully before applying the actual configuration (option 3)!

What would you like to do?

1) Show basic system information
2) Dry Run (Will save the configuration files in /usr/local/vpp/vpp-config/dryrun for inspection)
       and user input in /usr/local/vpp/vpp-config/configs/auto-config.yaml
3) Full configuration (WARNING: This will change the system configuration)
4) List/Install/Uninstall VPP.
5) Execute some basic tests.
9 or q) Quit
