module: ios_l2_interfaces
short_description: Resource module to configure L2 interfaces.
description:
  This module provides declarative management of Layer-2 interface on Cisco
  IOS devices.
version_added: 1.0.0
author:
  - Sagar Paul (@KB-petByte)
  - Sumit Jaiswal (@justjais)
notes:
  - Tested against Cisco IOSv Version 15.2 on CML.
  - This module works with connection C(network_cli).
    See U(https://docs.ansible.com/ansible/latest/network/user_guide/platform_ios.html)
  - The module examples uses callback plugin (stdout_callback = yaml) to generate task
    output in yaml format.

        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
