The goal of this document is to provide readers insight into the configuration of Dell EMC Networking switches using Dell EMC Networking Ansible roles. The Dell EMC Networking Ansible roles facilitate the provisioning of devices running Dell EMC Networking Operating Systems. Dell EMC Networking Ansible roles support configuration of all three Dell EMC Networking operating systems, i.e. OS6, OS9 and OS10. However, this document focuses on providing Ansible configuration examples for Dell EMC Networking OS9 switches, specifically for leaf-spine architectures.
