Table 48 Profiles > SSID Profile Settings (Continued) Field Default Description DSCP Mapping for WMM Voice AC DSCP Mapping for WMM Video AC DSCP Mapping for WMM BestEffort AC DSCP Mapping for WMM Background AC 902il No Compatibility Mode Deny Broadcast No Probes Local Probe Yes Response Local Probe 0 Request Threshold Disable Probe Yes Retry Battery Boost No Maximum 0 Transmit Failures Specify Differentiated Services Code Point (DSCP) mapping for wireless multimedia voice admission control. The supported range is 0 to 63. The IEEE 802.11e standard defines the mapping between WMM ACs and DSCP tags. The WMM AC mapping setting allows you to customize the mapping between WMM ACs and DSCP tags to prioritize various traffic types: voice, video, best effort, and background. Specify DSCP mapping for wireless multimedia video admission control. The supported range is 0 to 63. Specify DSCP mapping for wireless multimedia best effort admission control. The supported range is 0 to 63. Specify DSCP mapping for wireless multimedia background admission control. The supported range is 0 to 63. Enable or disable support for NEC 902il compatibility. 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. 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 AP), Dell PowerConnect W recommends that you enable the this option in the SSID profile. (Generating probe responses on the Dell PowerConnect W controller is an optimization that allows AOS to make better decisions.) This option is enabled by default. 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. 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 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. 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. 114 | Dell PowerConnect W Configuration Reference Dell PowerConnect W AirWave 7.2 | Configuration Guide
