ACL role
========
This role facilitates the configuration of an access-control list (ACL). It supports the configuration of different types of ACLs (standard and extended) for both IPv4 and IPv6, and assigns the access-class to the line terminals.
The ACL role requires an SSH connection for connectivity to a Dell EMC Networking 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.os9.os9 as a value
- If *os9_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
**os9_acl keys**

| ``state`` | string: absent,present\* | Deletes the ACL if set to absent | os9 |
> **NOTE**: Asterisk (\*) denotes the default value if none is specified.
Connection variables
--------------------
Ansible Dell EMC Networking roles require connection information to establish communication with the nodes in 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 /os9, null\* | This value is used to load the correct terminal and cliconf plugins to communicate with the remote device. |
> **NOTE**: Asterisk (_*_) denotes the default value if none is specified.
Dependencies
------------
The *os9_acl* role is built on modules included in the core Ansible code. These modules were added in Ansible version 2.2.0.
Example playbook
----------------
This example uses the *os9_acl* role to configure different types of ACLs (standard and extended) for both IPv4 and IPv6 and assigns the access-class to the line terminals. The example 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 networking OS name.
When *os9_cfg_generate* is set to true, it generates the configuration commands as a .part file in the *build_dir* path. By default it is set to false. It writes a simple playbook that only references the *os9_acl* role.
**Sample hosts file**
leaf1 ansible_host= <ip_address>
