running_config string								This option is used only with state parsed. The value of this option should be the output received from the EOS device by executing the command show running-config | section access-list. The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module's argspec and the value is then returned in the parsed key within the result.
state string							Choices: deleted merged ← overridden replaced gathered rendered parsed	The state the configuration should be left in.
