It would be an added statistic for "ignored" UDP multicast datagrams, incremented instead of UDP_MIB_NOPORTS. "UDP_MIB_IGNOREDMULTI" if you will. Similar in concept to what HP-UX NIC drivers would increment when they received a frame for which there was no bound protocol - "inbound unknown protocols" but not a drop http://ptgmedia.pearsoncmg.com/images/chap1_0130428167/elementLinks/01fig16.gif rick
