DSCP Mapping
for WMM Best-
Effort AC
Specify DSCP mapping for wireless multimedia best effort admission control. The supported
range is 0 to 63.
DSCP Mapping
for WMM
Background AC
Specify DSCP mapping for wireless multimedia background admission control. The
supported range is 0 to 63.
902il
Compatibility
Mode
No Enable or disable support for NEC 902il compatibility.
Deny Broadcast
Probes
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.
Local Probe
Response
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 Dell
PowerConnect W-Series AP), it is recommended that youenable the option in the SSID
profile. (Generating probe responses on the Dell PowerConnect W-Series controller is an
optimization that allows AOS to make better decisions.) This option is enabled by default.
Local Probe
Request
Threshold
0 The threshold, in dBm, for the bootstrap threshold to minimize the chance of the AP rebooting
due to temporary loss of connectivity with the Dell PowerConnect W controller.
Disable Probe
Retry
Yes Prevent (disable Yes) or accept (disable No) the resending of packets in local probe
operations.
NOTE: This setting requires a voice service license.
Battery Boost 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.
Maximum
Transmit Failures
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.
BC/MC Rate
Optimization
No Enables or disables scanning of all active stations currently associated to a mesh point to
select the lowest transmission rate based on the slowest connected mesh child. When
enabled, this setting dynamically adjusts the multicast rate to that of the slowest connected
mesh child. Multicast frames are not sent if there are no mesh children.
NOTE: The default value is recommended.
Strict Spectra-
link Voice
Protocol (SVP)
No Use this setting for SpectraLink VoIP devices. This setting automatically permits and
prioritizes the SpectraLink Voice Protocol (SVP).
