module: ios_acl_interfaces
short_description: Resource module to configure ACL interfaces.
description: This module configures and manages the access-control (ACL) attributes
  of interfaces on IOS platforms.
version_added: 1.0.0
author:
 - Sumit Jaiswal (@justjais)
 - Sagar Paul (@KB-perByte)
notes:
  - Tested against Cisco IOSv Version 15.2
  - This module works with connection C(network_cli).

      - The module, by default, will connect to the remote device and retrieve the current

        There are times when it is not desirable to have the task get the current running-config
        for every task in a playbook.  The I(running_config) argument allows the implementer
        to pass in the configuration to use as the base config for comparison. This
        value of this option should be the output received from device by executing
        command.

      - The state I(rendered) will transform the configuration in C(config) option to
        platform specific CLI commands which will be returned in the I(rendered) key
        within the result. For state I(rendered) active connection to remote host is
        not required.
      - The state I(gathered) will fetch the running configuration from device and transform
        it into structured data in the format as per the resource module argspec and
        the value is returned in the I(gathered) key within the result.
      - The state I(parsed) reads the configuration from C(running_config) option and
        transforms it into JSON format as per the resource module parameters and the
        value is returned in the I(parsed) key within the result. The value of C(running_config)
        option should be the same format as the output of command I(show running-config |
        include ^interface|ip access-group|ipv6 traffic-filter) executed on device.
        For state I(parsed) active
        connection to remote host is not required.
