IP Multicast Filtering Age-out Timer (30-9999) When this
timer expires and the switch has not observed (snooped) any
IGMP query packets asking whether any stations belong to any
Multicast groups, the switch itself will send out queries and
become the IGMP host on your network.
IP
Multicast
enables/disables the switch to intelligently forward IGMP and
Multicast packets instead of broadcasting (flooding) them on all
ports. This setting also enables IGMP Snooping, which enables
the switch to read IGMP packets being forwarded through the
switch in order to obtain forwarding information from them
(learn which ports contain Multicast members).
