# Ansible Role: enos_facts - Displays switch information
---
<add role description below>

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

## Requirements
---
<add role requirements information below>

- Ansible version 2.4 or later ([Ansible installation documentation](http://docs.ansible.com/ansible/intro_installation.html))
- Lenovo switches running ENOS version 8.4.1.0 or later
- an SSH connection to the Lenovo switch (SSH must be enabled on the network device)


## Role Variables
---
<add role variables information below>
Available variables are listed below, along with description.

`ansible_network_os` | Has to be `enos`
`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.

## Dependencies
---
<add dependencies information below>

- username.iptables - Configures the firewall and blocks all ports except those needed for web server and SSH access.
- username.common - Performs common server configuration.
- enos_facts.py - This module file will be located at lib/ansible/modules/network/enos/ of Ansible installation.
- enos.py - This module util file will be located at lib/ansible/module_utils/network/enos of Ansible installation.
- enos.py - This module plugin file will be located at lib/ansible/plugins/action of Ansible installation.
- enos.py - This module plugin file will be located at lib/ansible/plugins/cliconf of Ansible installation.
- enos.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 *enos_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.

```
[enos_facts]
10.241.105.24    ansible_connection=network_cli ansible_network_os=enos 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
---
<add playbook samples below>

To execute an Ansible playbook, use the following command:

```
ansible-playbook enos_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: enos_facts
   gather_facts: no
   connection: network_cli
   roles:
    - enos_facts
```
