groups for which the Switch has not recorded any group members. Select
Drop to discard the frame(s). Select Flooding to send the frame(s) to all

domains.
Select an IGMP version from the drop-down list box. The choices are IGMP-
v1, IGMP-v2, IGMP-v3 and None.
Generally, if you want to enable IGMP on the Switch, you should choose
IGMP-v3 as it is compatible with older versions. Choose an earlier version of
IGMP (IGMP-v2 or IGMP-v1) if the multicast hosts on your network can not
recognize IGMP version 3 or version 2 Query messages.
Click Apply to save your changes to the Switch's run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the Save
link on the top navigation panel to save your changes to the non-volatile
memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
