Global Flooding Parameter Descriptions
Parameter
Multicast Flooding
Multicast Outbound
to Secondary LANs
(Multicast Flooding
enabled)
Explanation
Determines the flooding structure when this access point
receives inbound multicast frames on non-root ports with
unknown destination addresses. Choose Disabled if you do not
want the access point to flood any inbound multicast frames.
Choose Universal if the access point forwards the multicast
frame to every port. This option uses more bandwidth. Use this
option if the root access point is supporting more than one
wireless hop to ensure that ARP requests and multicast traffic
are distributed.
Choose Hierarchical if the access point forwards the multicast
frame only to the port to which the root access point is
attached.
Specifies if outbound multicast frames with unknown
destination addresses are flooded toward secondary LANs.
Choose Enabled if the root access point controls flooding for
all the designated bridges on secondary LANs. Enabling this
parameter makes managing secondary LANs easier because you
do not need to set secondary LAN flooding parameters.
Choose Set Locally if the designated bridges control flooding
on their LANs.
