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 root 23781 1 99 14:00 ? 00:00:02 /usr/bin/vpp -c /etc/vpp/startup.conf 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 TenGigabitEthernet2/0/1 TenGigabitEthernet86/0/0 TenGigabitEthernet86/0/1 local0 1 2 3 4 0 down down down down 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. https://wiki.fd.io/view/VPP/Command-line_Interface_(CLI)_Guide 1. vppctl The usual way to access the cli is using the “vppctl”. It can be used from the linux command line or used to start a shell where VPP commands can executed from. Use exit or ctrl-d to exit from the shell.
    Executing vppctl from the linux command line: # vppctl show int Name Idx State Counter Count TenGigabitEthernet2/0/0 TenGigabitEthernet2/0/1 TenGigabitEthernet86/0/0 TenGigabitEthernet86/0/1 local0 1 2 3 4 0 up up up up down Excuting vppctl from the linux command line and creating a shell : root@tf-ucs-3:/scratch/jdenisco/fdio.1704/build-root# vppctl _______ _ _ _____ ___ __/ __/ _ \ (_)__ | | / / _ \/ _ \ _/ _// // / / / _ \ | |/ / ___/ ___/ /_/ /____(_)_/\___/ |___/_/ /_/ vpp# show int Name Idx State Counter Count TenGigabitEthernet2/0/0 TenGigabitEthernet2/0/1 TenGigabitEthernet86/0/0 TenGigabitEthernet86/0/1 local0 1 2 3 4 0 up up up up down 2. Some useful commands Here are a few useful VPP commands. 1. Show interface, clear interfaces These commands show and clear the interface counters. The short form of the “show interface” command is “show int” or “sh int”. vpp# show interface Name Idx State Counter Count
    4 354 3 238 1 3 8 746 7 630 1 7 2 TenGigabitEthernet2/0/0 TenGigabitEthernet2/0/1 TenGigabitEthernet86/0/0 1 2 3 up up up rx packets rx bytes tx packets tx bytes drops ip4 TenGigabitEthernet86/0/1 4 up rx packets rx bytes tx packets tx bytes drops ip4 local0 0 down drops vpp# clear interfaces vpp# sh int Name Idx State Counter Count TenGigabitEthernet2/0/0 TenGigabitEthernet2/0/1 TenGigabitEthernet86/0/0 TenGigabitEthernet86/0/1 local0 vpp# 1 2 3 4 0 up up up up down 2. Show error, Clear error These commands show and clear the error counters. The short form of the “show error” command is “sh err”. vpp# sh err Count 2 10 2 Node ip4-glean Reason ARP requests sent ip4-icmp-input echo replies sent arp-input ARP replies received
    Node ip4-glean Reason ARP requests sent ip4-icmp-input echo replies sent arp-input ARP replies received vpp# show errors Count 2 10 2 vpp# clear errors vpp# sh err Count Node Reason 3. Show hardware, clear hardware These commands show and clear the hardware counters. The link state is shown with this command. vpp# show hardware Name Idx Link Hardware TenGigabitEthernet2/0/0 1 up TenGigabitEthernet2/0/0 Ethernet address 90:e2:ba:96:cb:98 Intel 82599 carrier up full duplex speed 10000 mtu 9216 rx queues 1, rx desc 1024, tx queues 1, tx desc 1024 cpu socket 0 …. TenGigabitEthernet86/0/0 3 up TenGigabitEthernet86/0/0 Ethernet address 90:e2:ba:96:cd:4c Intel 82599 carrier up full duplex speed 10000 mtu 9216 rx queues 1, rx desc 1024, tx queues 1, tx desc 1024 cpu socket 1 tx frames ok tx bytes ok …. vpp# clear hardware vpp# show hardware 3 256
