| The vpp-config utility provides the user with several different menus. This allows the |
| user to configure ports, some performance characteristics, the number of huge pages |
| and install/uninstall the released FD.io packages. |
| |
| It is recommended that the menu command options, noted below as *"x)"*, are run in |
| this order (command option 4 first, then options 1,2,3): |
| |
| #. :ref:`4) List/Install/Uninstall VPP <config-command-four>` |
| #. :ref:`1) Show basic system information <config-command-one>` |
| #. :ref:`2) Dry Run <config-command-two>` |
| #. :ref:`3) Full Configuration <config-command-three>` |
| |
| Once vpp-config is installed as a root user, then run the following code: |
| |
| .. code-block:: console |
| |
| $ sudo -H bash |
| # vpp-config |
| |
| 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) |
| 4) List/Install/Uninstall VPP. |
| q) Quit |

| * Questions that ask [Y/n], the capital letter Y is the default answer. |
| * Numbers have their default within brackets, such as in [1024], the 1024 is the default. |
