Field Description
DTIM Period
TheDeliveryTracInformationMap(DTIM) messageis an element includedinsome
Beaconframes.Itindicateswhichclientstations,currentlysleepinginlow‐powermode,
havedatabueredontheaccesspointawaitingpick‐up.
TheDTIMperiodyouspecifyindicateshowoftentheclientsservedbythisaccesspoint

SpecifyaDTIMperiodwithinthegivenrange(1–255).
The measurement is in beacons. For example, if you set this eld to 1, clients will check
forbuereddataontheAPateverybeacon.Ifyousetthiseldto10,clientswillcheck
on every 10th beacon.
Beacon Interval
Beacon frames are transmitted by an access point at regular intervals to announce the
existence of the wireless network. The default behavior is to send a beacon frame once
every100milliseconds(or10persecond).TheBeaconIntervalvalueissetinmilliseconds.
Enteravaluefrom20to2000.
Automatic Channel
The channel denes the portion of the radio spectrum that the radio uses for transmitting
and receiving. The range of channels and the default channel are determined by the
Modeoftheradiointerface.WhentheAPboots,theAPscanstheRFareaforoccupied
channels and selects a channel from the available non‐interfering or clear channels.
However, channel conditions can change during operation.
Enabling the Automatic Channel makes APs assigned to this prole eligible for auto‐
channel selection.You can automatically or manually run the auto‐channel selection
algorithm to allow the controller to adjust the channel on APs as WLAN conditions
change.
By default, the global auto‐channel mode is set to manual.To enable the automatic
channelselectionmode,gototheAPManagement>RFManagementpageandselect
Fixed or Interval forthe Channel Plan mode.You can also run the automatic channel
selectionalgorithmmanuallyfromtheManualChannelPlanpage.
Note:IfyouassignastaticchanneltoanAPintheValidAPdatabaseorontheAdvanced
APManagementpage,theAPwillnotparticipateintheauto‐channelselection.
Automatic Power
ThepowerlevelaectshowfaranAPbroadcastsitsRFsignal.Ifthepowerlevelistoo
low, wireless clients will not detect the signal or experience poor WLAN performance. If
thepowerlevelistoohigh,theRFsignalmightinterferewithother
APswithinrange.
AutomaticpowerusesaproprietaryalgorithmtoautomaticallyadjusttheRFsignalto
broadcastfarenoughtoreachwirelessclients,butnotsofarthatitinterfereswithRF
signalsbroadcast by other APs.The powerlevel algorithm increases or decreases the
power level in 10% increments based on presence or absence of packet retransmission
errors.
Initial Power
The automatic power algorithm will not reduce the power below the number you set in
the default power eld. By default, the power level is 100%. Therefore, even if you enable
theautomaticpower,thepoweroftheRFsignalwillnotdecrease.Thepowerlevelisa
percentageofthemaximumtransmissionpowerfortheRFsignal.
APSD Mode

managementmethod.APSDisrecommendedifVoIPphonesaccessthenetworkthrough
theAP.
Frag Threshold
The fragmentation threshold limits the size of packets transmitted over the network.
Acceptablevaluesareevennumbersfrom256‐2345.Packetsthatareunderthecongured
size are not fragmented. A value of 2346 means that packets are not fragmented.
Short Retries
The value in this eld indicates the maximum number of transmission attempts on frame
sizeslessthanorequaltotheRTSThreshold.Therangeis1‐255.
Long Retries
The value in this eld indicates the maximum number of transmission attempts on frame
sizesgreaterthantheRTSThreshold.Therangeis1‐255.
