YAML and JSON Output Modules

yaml and json output modules display transformed lab topology in YAML or JSON format. You can invoke them by specifying -o yaml or -o json parameter in netlab create command.

Both output modules can take an optional destination file name (default: stdout).

Multiple formatting modifiers (separated with colons) can be used to reduce the amount of information in transformed lab topology:

  • nodefault – Remove default settings (defaults key).

  • noaddr – Remove address pools (addressing key).

  • nodes – Display the list of nodes.

  • links – Display the list of links.
