AirWave Wireless Management Suite | Configuration Guide Aruba Configuration Reference | 129802.11a BasicRates6, 12,and 24selectedSpecify the basic rates for the 802.11a radio.Max TransmitAttempts8 Specify the maximum number of transmit attempts. The supported range is 1 to 15.RTS threshold(bytes)2333 Specify the Request to Send parameter that defines the packet size sent by meshnodes. Mesh nodes transmitting frames larger than this threshold must issue requestto send (RTS) and wait for other mesh nodes to respond with clear to send (CTS) tobegin transmission. This helps prevent mid-air collisions.A smaller value causes more RTS packets to be sent more often, possibly impactingbandwidth. However, a smaller value may help the system recover more quickly frominterference or data packet collisions. Specify the size in bytes.ShortPreambleYes Instructs the AP to use short preambles in packets. Short preambles are oftenstandard in AP configuration.MaxAssociations64 Define the maximum associations to be supported by devices configured with thisSSID profile. The range is from 0 to 255.WirelessMultimedia(WMM)No Specify whether the devices are to support wireless multimedia (WMM): voice, video,best effort (BE), or background.WirelessMultimediaU-ASPDPowersaveYes Enable or disable unscheduled-automatic power save delivery. U-ASPD allows thesaving of WLAN client power. The WLAN client transmits frames that trigger theforwarding of data frames for a client that has been buffered at the AP for powersaving purposes.WMM TSPECMin InactivityInterval0 A WMM client can send a Traffic Specification (TSPEC) signaling request to the APbefore sending traffic of a specific AC type, such as voice. You can configure thecontroller so that the TSPEC signaling request from a client is ignored if the underlyingvoice call is not active; this feature is disabled by default. If you enable this feature,you can also configure the number of seconds that a client must wait to start the callafter sending the TSPEC request (the default is one second). You enable TSPECsignaling enforcement in the VoIP Call Admission Control profile. The supported rangeis 0 to 3,600,000 milliseconds.DSCPMapping forWMM VoiceACN/A Specify Differentiated Services Code Point (DSCP) mapping for wireless multimediavoice admission control. The supported range is 0 to 63.The IEEE 802.11e standard defines the mapping between WMM ACs andDifferentiated Services Codepoint (DSCP) tags. The WMM AC mapping setting allowsyou to customize the mapping between WMM ACs and DSCP tags to prioritizevarious traffic types: voice, video, best effort, and background.Table 48 Aruba Configuration > Profiles > EDCA AP Profile Settings (Continued)Field Default Description
