Table 7. Global Flooding Parameter Descriptions
Parameter Explanation
Multicast Flooding Determines the flooding structure when this
access point receives inbound multicast frames
on non-root ports with unknown destination
addresses:
Disabled: You do not want the access point to
flood any inbound multicast frames.
Universal: 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.
Hierarchical: The access point forwards the
multicast frame only to the port to which the root
access point is attached.
Multicast Outbound
to Secondary LANs Appears only if Multicast Flooding is enabled.
Specifies if outbound multicast frames with
unknown destination addresses are flooded
toward secondary LANs:
Enabled: 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.
Set Locally: The designated bridges control
flooding on their LANs.
