Ansible Role: cnos_save_sample - Saving the switch running configuration
This role is an example of using the cnos_save.py Lenovo module in the context of CNOS switch configuration. This module allows you to copy the running configuration of a switch over its startup configuration. It is recommended to use this module shortly after any major configuration changes so they persist after a switch restart.
The results of the operation can be viewed in results directory.
For more details, see Lenovo modules for Ansible: cnos_save.
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 |
|---|---|
ansible_connection |
Has to be network_cli |
ansible_network_os |
Has to be cnos |
ansible_ssh_user |
Specifies the username used to log into the switch |
ansible_ssh_pass |
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, g8332_cnos - G8332, NE10032 - NE10032, NE1072T - NE1072T, NE1032 - NE1032, NE1032T - NE1032T, NE2572 - NE2572, NE0152T - NE0152T) |
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_save.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_save_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_save_sample]
10.241.107.39 ansible_network_os=cnos ansible_ssh_user=<username> ansible_ssh_pass=<password> deviceType=g8272_cnos
10.241.107.40 ansible_network_os=cnos ansible_ssh_user=<username> ansible_ssh_pass=<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_save_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.
