# 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](http://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 --- | --- `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 To gather subsets you will specify the following variables to get appropriate data retrieved from the devices Variable | Description --- | --- `gather_subset` | When supplied, this argument will restrict the facts collected to a given subset. Possible values for this argument include all, hardware, config, and interfaces. Can specify a list of values to include a larger subset. Values can also be used with an initial C(M(!)) to specify that a specific subset should not be collected. Need to specify these variables in vars/main.yml under variable `cli` Variable | Description --- | --- `host` | Has to be "{{ inventory_hostname }}" `port` | Has to be`22` `username` | User Name of switch `password` | Password of switch `timeout` | time out value for CLI `authorize` | Whether u have to enter enable mode for data collection. `auth_pass`| Enable Password if required ## 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= ansible_ssh_pass= ``` **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_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 ``` ## License --- Copyright (C) 2017 Lenovo, Inc.
