Setting Description Defaults
Backoff Time After an AP changes channel or power settings, it
waits for the backoff time interval before it asks for a
new channel/power setting.
Range: 120–3600 seconds.
240 sec
Error Rate Threshold The minimum percentage of PHY errors and MAC
errors in the channel that will trigger a channel
change.
In 6.4.4.0 and later
releases:
n default-a: 70%
n default-g: 70%
In earlier 6.4.x
releases:
n default: 50%
Error Rate Wait Time Minimum time in seconds the error rate has to
exceed the Error Rate Threshold before it triggers a
channel change.
In 6.4.4.0 and later
releases:
n default-a: 90 sec
n default-g: 90 sec
In earlier 6.4.x
releases:
n default: 30 sec
Channel Quality Aware
Arm
Enable this feature to base ARM changes upon an
internally calculated channel quality metric. When
this feature is disabled, ARM initiates channel
changes based on thresholds defined in this profile,
and chooses the channel based on the calculated
interference index value. Default: Disabled
Disabled
Channel Quality
Threshold
Channel quality percentage below which ARM
initiates a channel change.
Range: 0-100%
70%
Channel Quality Wait
Time
If channel quality is below the specified channel
quality threshold for this wait time period, ARM
initiates a channel change.
Range:1-3600 seconds
120 seconds
Minimum Scan Time Minimum number of times a channel must be
scanned before it is considered for assignment.
Range: 0–2,147,483,647 scans. It is recommended to
use a Minimum Scan Time between 1–20 scans.
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.
Range: 0–20,000,000 bytes/second. (Specify 0 to
disable this feature.)
