module: netact_cm_command

short_description: Manage network configuration data in Nokia Core and Radio networks

version_added: "2.5"

description:
    netact_cm_command can be used to run various configuration management operations.
    This module requires that the target hosts have Nokia NetAct network management system installed.
    Module will access the Configurator command line interface in NetAct to upload network configuration to NetAct,
    run configuration export, plan import and configuration provision operations
    To set the scope of the operation, define Distinguished Name (DN) or Working Set (WS) or
    Maintenance Region (MR) as input
options:
    operation:
        description:
            Supported operations allow user to upload actual configuration from the network, to import and
            provision prepared plans, or export reference or actual configuration for planning purposes.
            Provision_Mass_Modification enables provisioning the same parameters to multiple network elements.
            This operation supports modifications only to one object class at a time. With this option
            NetAct Configurator creates and provisions a plan to the network with the given scope and options.
        required: true
        choices:
            - upload
            - provision
            - import
            - export
            - Provision_Mass_Modification
        aliases:
            - op
    opsName:
        description:
            - user specified operation name
        required: false
    DN:
        description:
            Sets the exact scope of the operation in form of a list of managed object
            Distinguished Names (DN) in the network.
            A single DN or a list of DNs can be given (comma separated list without spaces).
            Alternatively, if DN or a list of DNs is not given, working set (WS) or Maintenance Region (MR)
            must be provided as parameter to set the scope of operation.
        required: false

    WS:
        description:
            Sets the scope of the operation to use one or more pre-defined working sets (WS) in NetAct.
            A working set contains network elements selected by user according to defined criteria.
            A single WS name, or multiple WSs can be provided (comma-separated list without spaces).
            Alternatively, if a WS name or a list of WSs is not given, Distinguished Name (DN) or
            Maintenance Region(MR) must be provided as parameter to set the scope of operation.
        required: false
    MR:
        description:
            Sets the scope of the operation to network elements assigned to a Maintenance Region (MR)
            Value can be set as MR IDs including the Maintenance Region Collection (MRC)
            information (for example MRC-FIN1/MR-Hel).
            Multiple MRs can be given (comma-separated list without spaces)
            The value of this parameter is searched through MR IDs under given MRC. If there is no match,
            then it is searched from all MR names.
            Alternatively, if MR ID or a list or MR IDs is not given, Distinguished Name (DN) or Working Set (WS)
            must be provided as parameter to set the scope of operation.
        required: false
    planName:
        description:
            - Specifies a plan name.
        required: false

    fileName:
        description:
            - Specifies a file name. Valid for Import and Export operations.
        required: false
    inputFile:
        description:
            Specifies full path to plan file location for the import operation.
            This parameter (inputFile) or the fileName parameter must be filled. If both are present then
            the inputFile is used.
        required: false
    createBackupPlan:
        description:
            - Specifies if backup plan generation is enabled.
