Enable ARP
Flooding Check this check box to enable ARP flooding.
When an access point receives an ARP request,
it checks its ARP cache to determine if the
destination end device’s IP address is known.
If you enable ARP flooding and:
ˆ the destination end device is known, the
access point translates the ARP request into
a unicast frame, which is only forwarded to
the destination end device. Therefore, all end
devices do not need to wake up to listen to
the ARP request, which saves battery life.
ˆ the destination end device is not known, the
access point forwards the ARP request based
on its flooding and filtering settings.
If you disable ARP flooding, the access point
ignores ARP requests for destination end devices
that are not in its ARP cache. You should only
use this option if you have no IP devices in your
wireless network.
