Hello, snappi! Welcome to the Clab!

Overview

This is a simple lab where an Ixia-c-one node has two traffic ports connected back-2-back in a Containerlab environment. The goal is to demonstrate basics of creating a Python program to control Ixia-c via snappi SDK.

Prerequisites

Clone the repository

  1. Clone this repository to the Linux host where you want to run the lab. Do this only once.

    git clone --recurse-submodules https://github.com/open-traffic-generator/otg-examples.git

  2. Navigate to the lab folder

    cd otg-examples/clab/ixia-c-b2b

Prepare a snappi container image

Run the following only once, to build a container image where snappi program will execute:

sudo docker build -t snappi:local .

Deploy a lab

sudo -E containerlab deploy -t topo.yml

Run snappi test

sudo docker exec -it clab-ixcb2b-snappi bash -c "python otg.py"

Destroy the lab

sudo -E containerlab destroy -t topo.yml

Options for Linux VM deployment for Containerlab

Containerlab VM deployment on Mac using Multipass

  1. If you're on Mac, an example below can be used to create an Ubuntu 20.04LTS VM otg-demo, using Multipass. Ubuntu 22.04 is not yet supported for this test.

    multipass launch 20.04 -n otg-demo -c4 -m8G -d32G
multipass shell otg-demo
sudo apt update && sudo apt install docker.io -y
bash -c "$(curl -sL https://get.containerlab.dev)"

  2. Delete the VM after testing is done

    multipass stop otg-demo
multipass delete otg-demo

Containerlab VM deployment in Google Cloud

  1. Create a VM in a default VPC

    gcloud compute instances create otg-demo \
--subnet=default \
--machine-type=e2-standard-8 \
--image-family=ubuntu-2004-lts \
--image-project=ubuntu-os-cloud \
--boot-disk-size=30GB \
--boot-disk-device-name=otg-demo \
--tags=otg-demo

gcloud compute ssh otg-demo
sudo apt update && sudo apt install docker.io -y
bash -c "$(curl -sL https://get.containerlab.dev)"

  2. Delete all resources and the VM after testing is done

    gcloud compute instances delete otg-demo

Misc

CLI access to nodes

# ixia-c
sudo docker exec -it clab-ixcb2b-ixia-c sh
sudo docker exec -it clab-ixcb2b-snappi bash
