Setting Description
Time change. The supportedr ange for this settingi s 15–3600seconds.
Default:120 seconds
Minimum Scan
Time
Minimum number of times a channel must be scanned before it is considered for assignment. The
supportedrange for this setting is 0–2,147,483,647scans. Dell recommends a Minimum Scan Tim e
between1–20 scans.
Default:8 scans
LoadAware
ScanThreshol d
Loadaware ARM preserves network resources during periods of high traffic by temporarily halting ARM
scanningi fthe load for the AP gets too high.
TheLoad Aware Scan Threshold i sthe traffic throughput level an AP must reach before it stopsscanning.
Thesupported range for this setting is 0–20,000,000 bytes/second.(Specify 0 to disable thisfeature.)
Default:1250000 Bps
ModeAware
ARM
Ifenabled, ARMwil l turn APs into Air Monitors (AMs) if it detects higher coverage levels than necessary.
Thishel ps avoid higher levels of interference on the WLAN. Although this setting is disabled by default,
youmay want to enable this feature if your APs are deployed in close proximity (e.g. less than 60 feet
apart).
Modeaw are ARM turnsAir Monitors back into APs when they detect gaps in coverage. Note thatan Air
Monitorw ill not turn back into an AP i f it detectscl ient traffic (or client traffic increases), but will change
toan AP onl y if it detects coverage holes.
Default:disabled
ScanMode Bydefault, 802.11n-capable APs scan channels within all regulatory domains. To lim it theAP scans to just
theregulatory domain for that AP, click the Scan Mode drop-down listand select reg-domai n.
NOTE:Thi s settingdoes not appl y to APs thatdo notsupport 802.11n; these APs will scan their regul atory
domain only.
In the CLI
You must be in config mode to create, modify or delete an ARM profile using the CLI. Specify an existi ngA RMprofilewi tht he<profile-name> parametert o modify anexisti ngARM profile, or enter a newname to create anentirelynew profile.Configuration details and any defaultvalues for each of these parameters are described in Table 97. If yo u do notspecify a parameter for a new profile, that profile uses the default valuefor that parameter.P ut the no option beforeany parameterto remove the current valuefor t hat parameterand return it to its default setting. Enter exit to leavethe ARM profile mode.Use the following command to create or modify an ARM profile:
