The source can be either a + file with config or a template that will be merged during + runtime. By default the task will search for the source + file in role or playbook root folder in templates directory. + required: false + default: null + force: + description: + - The force argument instructs the module to not consider the + current devices running-config.

Setting this value to true will cause the module + to issue the command `show running-config all` to include all + device settings. + required: false + default: false + choices: BOOLEANS + backup: + description: + - When this argument is configured true, the module will backup + the running-config from the node prior to making any changes. + The backup file will be written to backup_{{ hostname }} in + the root of the playbook directory. + required: false + default: false + choices: BOOLEANS + ignore_missing: + description: + - This flag instructs the module to ignore lines that are missing + from the device configuration.
