Wireless Access Point
Configuring the Wireless AP 331
If you select On and an IAP is not the best choice for network
performance, that IAP will send an “AP Full” message in response to
Probe, Association, or Authentication requests. This deters persistent
clients from forcing their way onto overloaded IAPs.
Note that ACExpress load balancing is not used if:
• A station is re-associating—if it was already associated to this IAP, it
is allowed back on this IAP immediately. This prevents the station
from being bounced between different IAPs.
• The IAP’s Band, WiFi Mode, and Channel settings are not at their
default values. For example, if the IAP’s WiFi mode is set to 11n-only,
load balancing will not be used. See “IAP Settings” on page 312.
• If station counts (specified at the IAP, SSID, or band level) are already
exceeded.
• If a station has already been turned down a number of times when
attempting to associate, i.e., the station will eventually be allowed
onto the IAP after a number of attempts have failed.
Choose Off to disable load balancing.
27. ARP Filtering: Address Resolution Protocol finds the MAC address of a
device with a given IP address by sending out a broadcast message
requesting this information. ARP filtering allows you to reduce the
proliferation of ARP messages by restricting how they are forwarded
across the network.
You may select from the following options for handling ARP requests:
• Off: ARP filtering is disabled. ARP requests are broadcast to radios
that have stations associated to them.
• Pass-thru: The AP forwards the ARP request. It passes along only
ARP messages that target the stations that are associated to it. This is
the default value.
• Proxy: The AP replies on behalf of the stations that are associated to
it. The ARP request is not broadcast to the stations.
