module: iosxr_interfaces
short_description: Resource module to configure interfaces.
description: This module manages the interface attributes on Cisco IOS-XR network
  devices.
version_added: 1.0.0
author:
- Sumit Jaiswal (@justjais)
- Rohit Thakur (@rohitthakur2590)
notes:
- This module works with connection C(network_cli). See L(the IOS-XR Platform Options,../network/user_guide/platform_iosxr.html).

        - Administrative state of the interface.
        - Set the value to C(True) to administratively enable the interface or C(False)
          to disable it.
        type: bool
      speed:
        description:
        - Configure the speed for an interface. Default is auto-negotiation when not
          configured.

      mtu:
        description:
        - Sets the MTU value for the interface. Applicable for Ethernet interfaces
          only.
        - Refer to vendor documentation for valid values.

        - full
        - half
  running_config:
    description:
    - This option is used only with state I(parsed).
    - The value of this option should be the output received from the IOS-XR device
      by executing the command B(show running-config interface).
    - The state I(parsed) reads the configuration from C(running_config) option and
      transforms it into Ansible structured data as per the resource module's argspec
      and the value is then returned in the I(parsed) key within the result.
