Uninstalling FDIO, giving the ports back 20 

1.Overview

This document will describe downloading, installing and running FDIO. We will talk

about the installing FDIO, the build tree, configuration files and scripts. This isn’t

meant to be a detailed description, but more a way to quickly ramp up and understand

the basics of FDIO. VPP is a core technology in FDIO and thus referenced as VPP in

many places in this document.. In this doc commands that start with “# “ should be

root and “$ “ are not.

2. Configuration Utility

The VPP configuration can be used to safely and easily configure a system for use

with VPP. Information on how to use this utility can be found at the following:

https://wiki.fd.io/view/VPP/Configuration_Tool

3.Installing FDIO

Later in this document we describe how to build FDIO and its packages. This section

will describe how VPP can be installed and run without building the packages

The following link describes how to install FDIO from the packages. I will summarize

it here.

https://wiki.fd.io/view/VPP/Installing_VPP_binaries_from_packages

1. Installing with APT (Latest Released Version)

Create the file /etc/apt/sources.list.d/99fd.io.list with the contents shown below:

# cat /etc/apt/sources.list.d/99fd.io.list

deb [trusted=yes]

https://nexus.fd.io/content/repositories/fd.io.ubuntu.xenial.main/ ./

Install the packages with the following:

# apt-get update

…..

Reading package lists...

# apt-get install vpp-lib

Reading package lists... Done

Building dependency tree

….. !!!!!!

# apt-get install vpp

Reading package lists... Done

Building dependency tree

…. !!!!

# apt-get install vpp-plugins

Reading package lists... Done

Building dependency tree

…. !!!!!

2. Installing with YUM (Latest Released Version)

Create a file /etc/yum.repos.d/fdio-release.repo with contents shown below:

[fdio-stable-1801]

name=fd.io stable/1801 branch latest merge

baseurl=https://nexus.fd.io/content/repositories/fd.io.centos7/

enabled=1

gpgcheck=0

Install VPP:

# yum install vpp

3. Start and quickly verify VPP installation

When VPP is started it will take all the available interfaces. VPP should be started

after the install. VPP can also be started or restarted after installation with the service

command.

Start VPP:

# service vpp start

Verify VPP is started using the ps command.

# ps -eaf | grep vpp

root !!!!23781 1 99 14:00 ? !!!!!!!00:00:02 /usr/bin/vpp -c /etc/vpp/startup.conf

root !!!!23904 11029 !0 14:00 pts/1 !!!00:00:00 grep --color=auto vpp

Verify that vpp is using some interfaces using the vppctl command. The vppctl

command is used to run the vpp cli.

# vppctl show int

!!!!!!!!!!!!!Name !!!!Idx State !!!!!Counter Count !

TenGigabitEthernet2/0/0 !!!!!!!!!!1 down

TenGigabitEthernet2/0/1 !!!!!!!!!!2 down

TenGigabitEthernet86/0/0 !!!!!!!!!3 down

TenGigabitEthernet86/0/1 !!!!!!!!!4 down

local0 !!!!!!!!!!!!!!!!!!!!!!!!!!!0 down

4. Setting the Interface IP Addresses

We can then add IP addresses to the interfaces. Once this is done we can then ping

these addresses from a live network.

# vppctl set int ip address TenGigabitEthernet86/0/0 30.0.0.2/8

# vppctl set int state TenGigabitEthernet86/0/0 up

# vppctl set int ip address TenGigabitEthernet86/0/1 40.0.0.2/8

# vppctl set int state TenGigabitEthernet86/0/1 up

Verify the addresses are set “show interface address”

# vppctl show interface address

TenGigabitEthernet86/0/0 (up):

!30.0.0.2/8

TenGigabitEthernet86/0/1 (up):

!40.0.0.2/8

local0 (dn):

The interfaces TenGigabitEthernet86/0/0 and TenGigabitEthernet86/0/1 now have IP

addresses. You can now ping those IP addresses from another system.

$ ping 30.0.0.2

PING 30.0.0.2 (30.0.0.2) 56(84) bytes of data.

64 bytes from 30.0.0.2: icmp_seq=1 ttl=255 time=0.729 ms

64 bytes from 30.0.0.2: icmp_seq=2 ttl=255 time=0.540 ms

VPP is now installed and operational!!

4.CLI

FDIO comes with a rudimentary command line interface. The FDIO CLI is a work in

progress. It is expected to be an ongoing work and to be updated regularly. It does

have command line recall and a rudimentary help.

Although not a complete description of the CLI, a decent description can be found at

the following link.
