AAA role
========
This role facilitates the configuration of authentication, authorization, and acccounting (AAA). It supports the configuration of RADIUS server, TACACS server, and AAA. This role is abstracted for Dell EMC PowerSwitch platforms running Dell EMC SmartFabric OS10.
The AAA role requires an SSH connection for connectivity to a Dell EMC SmartFabric OS10 device. You can use any of the built-in OS connection variables.
Role variables
--------------
- Role is abstracted using the `ansible_network_os` variable that can take `dellemc.os10.os10` as the value
- If `os10_cfg_generate` is set to true, the variable generates the role configuration commands in a file
- Any role variable with a corresponding state variable set to absent negates the configuration of that variable
- Setting an empty value for any variable negates the corresponding configuration
- Variables and values are case-sensitive

Connection variables
--------------------
Ansible Dell EMC network roles require connection information to establish communication with the nodes in your inventory. This information can exist in the Ansible *group_vars* or *host_vars* directories or inventory, or in the playbook itself.
| Key | Required | Choices | Description |
|-------------|----------|------------|-----------------------------------------------------|
| ``ansible_host`` | yes | | Specifies the hostname or address for connecting to the remote device over the specified transport |
| ``ansible_port`` | no | | Specifies the port used to build the connection to the remote device; if value is unspecified, the `ANSIBLE_REMOTE_PORT` option is used; it defaults to 22 |
| ``ansible_ssh_user`` | no | | Specifies the username that authenticates the CLI login for the connection to the remote device; if value is unspecified, the `ANSIBLE_REMOTE_USER` environment variable value is used |
| ``ansible_ssh_pass`` | no | | Specifies the password that authenticates the connection to the remote device |
| ``ansible_become`` | no | yes, no\* | Instructs the module to enter privileged mode on the remote device before sending any commands; if value is unspecified, the `ANSIBLE_BECOME` environment variable value is used, and the device attempts to execute all commands in non-privileged mode |
| ``ansible_become_method`` | no | enable, sudo\* | Instructs the module to allow the become method to be specified for handling privilege escalation; if value is unspecified, the `ANSIBLE_BECOME_METHOD` environment variable value is used |
| ``ansible_become_pass`` | no | | Specifies the password to use if required to enter privileged mode on the remote device; if ``ansible_become`` is set to no this key is not applicable |
| ``ansible_network_os`` | yes | os10, null\* | Loads the correct terminal and cliconf plugins to communicate with the remote device |
> **NOTE**: Asterisk (*) denotes the default value if none is specified.
Example playbook
----------------
This example uses the *os10_aaa* role to configure AAA for radius and TACACS servers. It creates a *hosts* file with the switch details and corresponding variables. The hosts file should define the `ansible_network_os` variable with the corresponding Dell EMC OS10 name.
When `os10_cfg_generate` is set to true, the variable generates the configuration commands as a .part file in the *build_dir* path. By default, it is set to false and it writes a simple playbook that only references the *os10_aaa* role.
