Ansible Role: cnos_showrun_sample - Displays Running Configuration inforamtion

---

This role is an example of using the cnos_showrun.py Lenovo module in the context of CNOS switch configuration. This module allows you to view the switch information. It executes the display running-config 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_showrun.

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)

Role Variables

Available variables are listed below, along with description.

The following are mandatory inventory variables:

Variable	Description
username	Specifies the username used to log into the switch
password	Specifies the password used to log into the switch
enablePassword	Configures the password used to enter Global Configuration command mode on the switch (this is an optional parameter)
hostname	Searches the hosts file at /etc/ansible/hosts and identifies the IP address of the switch on which the role is going to be applied
deviceType	Specifies the type of device from where the configuration will be backed up (g8272_cnos - G8272, g8296_cnos - G8296)

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_showrun.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_showrun_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 hosts file for the role is located in the main directory of the role.

[cnos_showrun_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_showrun_sample.yml -vvv

-vvv is an optional verbos 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 Show Sys Info
   hosts: cnos_showrun_sample
   gather_facts: no
   connection: local
   roles:
