This module + allows implementors to work with the device running-config. It + provides a way to push a set of commands onto a network device + by evaluating the current running-config and only pushing configuration + commands that are not already configured. The config source can + be a set of commands or a template. +extends_documentation_fragment: dellos6 +options: + src: + description: + - The path to the config source. The source can be either a + file with config or a template that will be merged during + runtime. By default the task will first search for the source + file in role or playbook root folder in templates unless a full + path to the file is given. + required: true + force: + description: + - The force argument instructs the module not to consider the + current device running-config. When set to true, this will + cause the module to push the contents of I(src) into the device + without first checking if already configured. This argument is + mutually exclusive with I(config). + required: false + default: false + choices: [ "true", "false" ] + 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. This argument is + mutually exclusive with I(config). + required: false + default: false + choices: [ "true", "false" ] + config: + description: + - The module, by default, will connect to the remote device and + retrieve the current running-config to use as a base for comparing + against the contents of source. There are times when it is not + desirable to have the task get the current running-config for + every task. The I(config) argument allows the implementer to + pass in the configuration to use as the base config for + comparison.
