Can I Use Ansible in Cisco CML 2?
Introduction
Cisco CML 2 (Cisco Network Management Layer 2) is a powerful tool for managing and configuring Cisco devices. It provides a comprehensive set of features and capabilities for network administrators to manage their networks efficiently. However, one of the challenges that many network administrators face is the complexity of managing Cisco devices using traditional methods. This is where Ansible comes in – a popular open-source automation tool that can simplify the process of managing Cisco devices.
What is Ansible?
Ansible is an open-source automation tool that allows users to define a set of tasks to be executed on a collection of devices. It uses a simple and intuitive syntax to define these tasks, making it easy to manage complex networks. Ansible is based on the concept of roles, which are reusable sets of tasks that can be applied to a collection of devices.

Example Ansible Playbook
Here is an example Ansible playbook that demonstrates how to configure a Cisco router:
---
- name: Configure Cisco Router
hosts: router
become: yes
tasks:
- name: Configure IP address
ip:
address: 192.168.1.100
netmask: 255.255.255.0
gateway: 192.168.1.1
- name: Configure DNS server
dns:
servers: ['8.8.8.8', '8.8.4.4']
nameservers: ['8.8.8.8', '8.8.4.4']This playbook defines two tasks: one to configure the IP address and one to configure the DNS server.
