# 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](http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_save.html&cp=0_3_1_0_4_3). ## Requirements --- - Ansible version 2.2 or later ([Ansible installation documentation](https://docs.ansible.com/ansible/intro_installation.html)) - 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_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 username= password= deviceType=g8272_cnos 10.241.107.40 username= password= deviceType=g8272_cnos ``` **Note:** You need to change the IP addresses to fit your specific topology. You also need to change the `` and `` 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. ``` - name: Module to do save configurations hosts: cnos_save_sample gather_facts: no connection: local roles: - cnos_save_sample ``` ## License --- Copyright (C) 2017 Lenovo, Inc.
