Devices such as the HP Procurve Series 5300XL and the HP Procurve switch
1600M/2400M/2424M/4000M/8000M having static Traffic/Security filters con-
figured with a “Multicast” filter type and a “Multicast Address” in this range
will continue in effect unless IGMP learns of a multicast group destination in
this range. In that case, IGMP takes over the filtering function for the multicast
destination address(es) for as long as the IGMP group is active. If the IGMP
group subsequently deactivates, the static filter resumes control over traffic
to the multicast address formerly controlled by IGMP.
