The ‘rfilter’ function allows you to choose whether or not DATA frames with KNOWN group multicast
addresses are sent to the ‘router’ ports (links to other switches). Control packets (Join, Leave) will be sent to
the router(s) regardless of this setting. “Known” can be known from dynamic IGMP Snooping operation
and/or from setting of “static filters” (see below).
In firmware version 8.09 and subsequent the default is
that the Router Multicast Data Filter is enabled for all ports, so any router ports do not get DATA
frames with KNOWN multicast destination addresses unless a join to a specific multicast address has
been received on that port. ( Joins over-ride rfilter.) Rfilter can be set for individual ports: any, all, or
none. For each port rfilter will have an impact only if that port is manually or dynamically chosen as
a router port.
Example of entering ports for rfilter to be applied:
(
One does not have to manually enter anything
, unless wanting to limit data to some ‘router’ (switch link) ports.)
