Dependencies

---

• username.iptables - Configures the firewall and blocks all ports except those needed for web server and SSH access.
• username.common - Performs common server configuration.
• cnos_facts.py - This module file will be located at lib/ansible/modules/network/cnos/ of Ansible installation.
• cnos.py - This module util file will be located at lib/ansible/module_utils/network/cnos of Ansible installation.
• cnos.py - This module plugin file will be located at lib/ansible/plugins/action of Ansible installation.
• cnos.py - This module plugin file will be located at lib/ansible/plugins/cliconf of Ansible installation.
• cnos.py - This module plugin file will be located at lib/ansible/plugins/cliconf of Ansible installation.
• /etc/ansible/hosts - You must edit the /etc/ansible/hosts file with the device information of the switches designated as leaf switches. You may refer to cnos_command_sample_hosts for a sample configuration.

Ansible keeps track of all network elements that it manages through a hosts file. Before the execution of a playbook, the hosts file must be set up.

Open the /etc/ansible/hosts file with root privileges. Most of the file is commented out by using #. You can also comment out the entries you will be adding by using #. You need to copy the content of the hosts file for the role into the /etc/ansible/hosts file. The sample hosts file for the role is located in the main directory.

[cnos_facts]
10.241.105.24    ansible_connection=network_cli ansible_network_os=cnos ansible_ssh_user=<username> ansible_ssh_pass=<password>

Note: You need to change the IP addresses to fit your specific topology. You also need to change the <username> and <password> to the appropriate values used to log into the specific Lenovo network devices.

Example Playbook

---

To execute an Ansible playbook, use the following command:

ansible-playbook cnos_facts_sample.yml -vvv

-vvv is an optional verbose command that helps identify what is happening during playbook execution. The playbook for each role is located in the main directory of the solution.

 - name: Module to  do some CLI Command configurations
   hosts: cnos_facts
   gather_facts: no
   connection: network_cli
   roles:
    - cnos_facts
