Configuring ARM Settings via the CLI
You must be in config mode to create, modify or delete an ARM profile using the CLI. Specify an existing ARM
profile with the <profile-name> parameter to modify an existing ARM profile, or enter a new name to create an
entirely new profile.
Configuration details and any default values for each of these parameters are described in Table 34 on page 142.
If you do not specify a parameter for a new profile, that profile uses the default value for that parameter. Put the
no option before any parameter to remove the current value for that parameter and return it to its default setting.
Enter exit to leave the ARM profile mode.
Use the following command to create or modify an ARM profile:
rf arm-profile <profile>
40MHz-allowed-bands {All|None|a-only|g-only}
acceptable-coverage-index <number>
active-scan (not intended for use)
assignment {disable|maintain|multi-band|single-band}

error-rate-threshold <percent>
error-rate-wait-time <seconds>

noise-threshold <number>

rogue-ap-aware
Noise Wait Time Minimum time in seconds the noise level has to exceed the Noise Threshold before it triggers a channel
change. The range of possible values is 120–3600 seconds.
Default: 120 seconds
Minimum Scan
Time
Minimum number of times a channel must be scanned before it is considered for assignment. The supported
range for this setting is 0–2,147,483,647 scans. Dell recommends a Minimum Scan Time between 1–20 scans.
Default: 8 scans
Load Aware Scan
Threshold
Load aware ARM preserves network resources during periods of high traffic by temporarily halting ARM
scanning if the load for the AP gets too high.
The Load Aware Scan Threshold is the traffic throughput level an AP must reach before it stops scanning.
The supported range for this setting is 0–20000000 bytes/second. (Specify 0 to disable this feature.)
Default: 1250000 Bps
Mode Aware
ARM
If enabled, ARM will turn APs into Air Monitors (AMs) if it detects higher coverage levels than necessary.
This helps avoid higher levels of interference on the WLAN. Although this setting is disabled by default, you
may want to enable this feature if your APs are deployed in close proximity (e.g. less than 60 feet apart).
Mode aware ARM turns Air Monitors back into APs when they detect gaps in coverage. Note that an Air
Monitor will not turn back into an AP if it detects client traffic (or client traffic increases), but will change to
an AP only if it detects coverage holes.
Default: disabled
