Ansible Role: cnos_facts_sample - Displays switch inforamtion
This role is an example of using the cnos_facts.py Lenovo module in the context of CNOS switch configuration. This module allows you to view the switch information. It executes the display sys-info CLI command on a switch and returns a file containing all the system information of the target network device.
The results of the operation can be viewed in results directory.
For more details, see Lenovo modules for Ansible: cnos_facts.
Requirements
- Ansible version 2.2 or later (Ansible installation documentation)
- Lenovo switches running CNOS version 10.2.1.0 or later
- an SSH connection to the Lenovo switch (SSH must be enabled on the network device)

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 modules needs to be present in the library directory of the role.
- cnos.py - This module needs to be present in the PYTHONPATH environment variable set in the Ansible system.
- /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_facts_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_sample]
10.241.107.39 username=<username> password=<password> deviceType=g8272_cnos
10.241.107.40 username=<username> password=<password> deviceType=g8272_cnos
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
