IMPORTANT: If you enable this
option, you must also enable
the Broadcast-Filter ARP
parameter in the stateful
firewall configuration to prevent
ARP requests from being
dropped. Note also that
although a virtual AP profile can
be replicated from a master
controller to local controllers,
stateful firewall settings do not.
If you select the broadcast-
filter all option for a Virtual AP
Profile on a master controller,
you must enable the
broadcast-filter arp setting on
each individual local controller.
l arp
If enabled, all broadcast ARP
requests are converted to
unicast and sent directly to the
client. You can check the status
of this option using the show
ap active and the show
datapath tunnel command. If
enabled, the output will display
the letter a in the flags column.
Do not enable this option for
virtual APs configured in bridge
forwarding mode. This
configuration parameter is only
intended for use for virual APs
in tunnel mode. In tunnel mode,
all packets travel to the
controller, so the controller is
able to convert ARP requests
directed to the broadcast
address into unicast. When a
virtual AP is configured to use
bridge forwarding mode, most
data traffic stays local to the AP,
and the controller is not able to
convert that broadcast traffic.
