It's feasible - you could create a type and provider that connects
to the switch and interacts with the CLI to retrieve the
configuration, manipulate it in some way (depending on how complex
the format is) and then send it back and apply it.
Obviously there would be limitations - no Factor facts and you'd
have to create a dummy node I guess because the switch wouldn't be a
real "node".
Others may have niftier ideas on how to do this - an easier
mechanism might be use Puppet's REST API to integrate with the
switches own management tool if it has an exposed API.
