forward all multicast traffic to a multicast-enabled router. Otherwise,
the Switch will forward all multicast traffic to any IP router.
Only administrator-level users can issue this command.

traffic to flood within a given IP interface.

disable forwarding all multicast traffic to a multicast-enabled routers.
The Switch will then forward all multicast traffic to any IP router.
