Return Values 

Common return values are documented here, the following are the fields unique to this module:

Key	Description
after list / elements=string	The resulting configuration module invocation. Returned: when changed Sample: `["The configuration returned will always be in the same format as the parameters above.\n"]`
after(generated) list / elements=string	The generated configuration module invocation. Returned: when `check_mode` Sample: `["The configuration returned will always be in the same format\n as the parameters above.\n"]`
before list / elements=string	The configuration prior to the module invocation. Returned: always Sample: `["The configuration returned will always be in the same format as the parameters above.\n"]`
commands list / elements=string	The set of commands pushed to the remote device. Returned: always Sample: `["command 1", "command 2", "command 3"]`
