Ansible Role: cnos_facts - Displays switch information

Collects a base set of device facts from a remote Lenovo device running on CNOS. This module prepends all of the base network fact keys with C(ansible_net_). The facts module will always collect a base set of facts from the device and can enable or disable collection of additional facts.

Requirements

Ansible version 2.6 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 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
