Aruba Networks Version 3.3 manual Minimum Scan Time Sec

Page 58

Aruba recommends that the above settings should be run for a minimum of one hour, and if possible overnight. Once the network has settled, the following configuration should be used for normal ARM operation. These are the default settings.

Parameter	Value
---------	-----
Assignment	single-band
Client Aware	Enabled
Max Tx Power	30	dBm
Min Tx Power	11	dBm
Multi Band Scan	Enabled
Rogue AP Aware	Disabled
Scan Interval	10	sec
Scanning	Enabled
Scan Time	110 msec
Power Save Aware Scan	Enabled
Ideal Coverage Index	5
Acceptable Coverage Index	2	sec
Wait Time	15	sec
Free Channel Index	25
Backoff Time	240 sec
Error Rate Threshold	50	%
Error Rate Wait Time	30	sec
Noise Threshold	75	-dBm
Noise Wait Time	120 sec
Minimum Scan Time	8 sec

The wireless administrator should be aware that the aggressive settings may cause connectivity issues for clients when the AP suddenly changes power and channel settings because both client and voice aware features are disabled. However, Aruba recommends going through this phase as a best practice to arrive at an optimal radio configuration.
