Stackable NWay Ethernet Switch User's Guide
Items in the above window are defined as follows:
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 Filtering (IGMP Snooping) This enables or 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).
The bottom of this screen contains a command for VLAN settings that leads to the IEEE 802.1Q IGMP
