To access the IGMP Configuration screen, select Configure Filtering and Forwarding Table from the
System Configuration menu. Then select Configure IGMP from the bottom of the Configure Filtering
and Forwarding table screen. The following screen appears:
Figure 6-24. IGMP Configuration screen
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/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
Configuration menu. Highlight Configure 802.1Q IGMP and press Enter to access this screen:
