Default Description
N/A Specify Differentiated Services Code Point (DSCP) mapping for wireless multimedia
video admission control. The supported range is 0 to 63.
N/A Specify Differentiated Services Code Point (DSCP) mapping for wireless multimedia
best effort admission control. The supported range is 0 to 63.
N/A Specify Differentiated Services Code Point (DSCP) mapping for wireless multimedia
background admission control. The supported range is 0 to 63.
No Enable or disable support for NEC 902il compatibility.
No Deny or accept broadcast probes. This setting is used in conjunction with Local Probe
Response. An AP broadcasts its configured service set identifier (SSID), which
corresponds to a specific wireless local area network (WLAN). Wireless clients
discover APs by listening for broadcast beacons or by sending active probes to
search for APs with a specific SSID.
Yes For deployments where there are expected to be considerable delays between the
controller and APs (for example, in a remote location where an AP is not in range of
another Aruba AP), Aruba recommends that you enable the "local probe response"
option in the SSID profile. (Generating probe responses on the Aruba controller is an
optimization that allows ArubaOS to make better decisions.) This option is enabled by
default in the SSID profile. You can also increase the value for the bootstrap threshold
in the AP System profile to minimize the chance of the AP rebooting due to temporary
loss of connectivity with the Aruba controller.
Yes Prevent (disable Yes) or accept (disable No) the resending of packets in local probe
operations.
NOTE: This setting requires a voice service license.
No Battery boost converts all multicast traffic to unicast before delivery to the client. This
feature is disabled by default. Enabling this feature on an SSID allows you to set the
DTIM interval from 10 - 100 (the previous allowed values were 1 or 2), equating to
1,000 - 10,000 milliseconds. This longer interval keeps associated
wireless clients from activating their radios for multicast indication and delivery, leaving
them in powersave mode longer, and thus lengthening battery life. The DTIM
configuration is performed on the WLAN, so no configuration is necessary on the client.
NOTE: This setting requires a voice service license.
NOTE: Although you can enable battery boost on a per-virtual AP basis, it must be
enabled for any SSIDs that support voice traffic.
Although the multicast to unicast conversion generates more traffic, that traffic is
buffered by the AP and delivered to the client when the client emerges from power-
save mode. An associated parameter available on some clients is the Listening
Interval (LI). This defines the interval (in number of beacons) after which the client
must wake to read the Traffic Indication Map (TIM). The TIM indicates whether there is
buffered unicast traffic for each sleeping client. With battery boost enabled, the DTIM
is increased but multicast traffic is buffered and delivered as unicast. Increasing the LI
can further increase battery life, but can also decrease client responsiveness.
0 Specify the maximum number of transmit failures to be supported before a radio is
considered to be down. A setting of 0 disables this feature.
