In addition to installing the requirements for running the Python code for CNaaS-NMS you might also want a test environment so you can run integration tests for your newly developed code. For this you will need docker to run all the components of CNaaS, and a virtualization software to run some virtual switches. In this example we will use VirtualBox and Arista vEOS switches.

Download the VMDK for Arista vEOS (tested with vEOS-lab-4.22.3M.vmdk , possibly issues with early 4.23 releases?). Copy this file into three new VMDK files that we will use to create the actual VMs: eosdist1.vmdk , eosdist2.vmdk , and eosaccess.vmdk

Then start VirtualBox and create three new VMs, using 2 GB memory each and choose to point them to an existing harddrive file (you will need to "add" the VMDK files you copied earlier to the "Virtual media manager" in VirtualBox). After creating the new VMs, we need to configure the network adapters. Before we can do this go into the menu  File→Host network manager... in VirtualBox and create a new network called vboxnet1 for example, and enter IP 10.100.2.2 / 255.255.255.0 (no DHCP server). Then configure the VMs with the following network adapters:

eosdist1:

Make sure all NICs are Intel PRO/1000 , and NIC 2-4 have Promiscous mode: Allow all

NIC1: NAT (Management1)

NIC2: Host-only adapter: cnaas (Ethernet1)

NIC3: Internal network: link_d1a1 (Ethernet2)

NIC4: Internal network: link_d1d2 (Ethernet3)

eosdist2:

Make sure all NICs are Intel PRO/1000 , and NIC 2-4 have Promiscous mode: Allow all

NIC1: NAT (Management1)

NIC2: Host-only adapter: cnaas (Ethernet1)

NIC3: Internal network: link_d2a1 (Ethernet2)

NIC4: Internal network: link_d1d2 (Ethernet3)

eosaccess:

Make sure all NICs are Intel PRO/1000 , and NIC 2-4 have Promiscous mode: Allow all

NIC1: NAT (Management1)

NIC2: Host-only adapter: cnaas (Ethernet1)

NIC3: Internal network: link_d1a1 (Ethernet2)

NIC4: Internal network: link_d2a1 (Ethernet3)
