Mellanox has a Ethernet Configurator which you can even use for other model.

Here’s how it works:
Choose the following:
1. Choose the setup

• 1 switch
• 2 switches connected with mLAG
• 5 switches: testing both mLAG as well as leaf spine (BGP/ECMP) – simple L3/VTEP/VXLAN Routing (VXLAN on Cumulus only for now)

2. Choose the speed of the host/NIC

• 10/25/100GbE

3. Choose the operating system

• ONYX
• Cumulus Linux

What you get is:
1. Topology: how to connect, which specific ports should be used

2. Solution brief for the selected scenario

3. One Click Configuration files:

• For the CLI guys: running config
• For the Ansible guys: Ansible playbooks (ONYX Ansible for mLAG and L3 will be added soon)
