If you are attending the NoF Tutorial session session (IEEE NoF tutorial), kindly download and install following, before the hands-on.
| System / Software | Source / Image / command / | Comments |
|---|---|---|
| Virtualization /Hypervisor | Oracle Virtualbox | To run VMs. |
| Virtual Machine | Download-link | For running Test and DUTs |
| Create 2 VMs | Step-1 | DUT and TGEN |
| Exchange of SSH-Keys between VMs | Step-2 | |
| Install New Version of T-Rex | Step-3 | |
| Install Test Automation Tools | Step-4 |
The Installation and configuration details are provided below.
...
- VM1 (DUT) : This is just a standard VM-from-ISO installation procedure. You will find many step-by-step description Ex: https://linuxhintitsfoss.com/install_ubuntu_18-04_virtualbox/-linux-in-virtualbox on this, including Videos (Ex: https://www.youtube.com/watch?v=QbmRXJJKsvs) .
- Please ensure that number of interfaces are 4 and configured according to the table above.
- VM2 (TGEN): Same as above - or you can just clone it!.
- Please ensure that number of interfaces are 4 and configured according to the table above.
| Network | Network/Adapter Type (Virtualbox) | Interfaces on DUT | Interfaces on TGen | Comments |
|---|---|---|---|---|
| test1 | Internal | eth3 | eth3 | Inter-VM ONLY |
| test2 | Internal | eth2, | eth2, | Inter-VM ONLY |
| admin | Bridged | eth1 | eth1 | Communicate with VMs from Host. |
| Internet | NAT | eth0 | eth0 | For Internet Access |
The names of the interfaces maybe different - for example on Ubuntu it may be enp0s2/3/4...
...
- If no identity is created yet (ex: if you don't find id_rsa.pub in ~/.ssh folder) Run ssh-keygen. It will generate the necessary identify.
- Use ssh-copy-id command. ssh-copy-id username_of_tgen_vm@ipaddress_of_tgen_vm
Step-3: Install New Version of T-Rex.
(a) INSTALL-TRex
sudo apt -y install zlib1g-dev build-essential python python3-distutils git clone https://github.com/cisco-system-traffic-generator/trex-core.git cd trex-core/ cd linux_dpdk ./b configure ./b build cd .. sudo cp scripts/cfg/simple_cfg.yaml /etc/trex_cfg.yaml
(b) Find PCIs
lspci | grep Eth 00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) 00:08.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) 00:09.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)

Step-4: Download and Install Test Automation Tools.
(a) Installing VSPERF on DUT-VM
Instructions to install and configure (including tuning) VSPERF can be found here
You may have to configure hugepages before running the install script - by running following commands:
- mkdir -p /mnt/huge
- mount -t hugetlbfs nodev /mnt/huge
- echo "vm.nr_hugepages=64" >> /etc/sysctl.conf
(b) Download functest and x-testing.
