Specify the action to perform when the Switch receives an unknown multicast frame.
Unknown multicast frames are addressed to multicast 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 ports.
Index
This field displays an index number of an entry.
Network
This field displays the IP domain configured on the Switch.
Refer to
for more information on configuring IP domains.
Version
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.
Apply
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.
Cancel
Click Cancel to begin configuring this screen afresh.
