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 evaluting 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: ios +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: false + default: null + 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. + required: false + default: false + choices: BOOLEANS + include_defaults: + description: + - The module, by default, will collect the current device + running-config to use as a base for comparision to the commands + in I(src). Setting this value to true will cause the command + issued to add any necessary flags to collect all defaults as + well as the device configuration. If the destination device + does not support such a flag, this argument is silently ignored. + 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 instruts the module to ignore lines that are missing + from the device configuration.
