MSM7xx Controllers Configuration Guide v6.4.0

• 15 - 29 dBm: HP 517 operating at 2.4 GHz.
• 16 - 28 dBm: HP 517 operating at 5 GHz.
Automatic power control
Select this checkbox to have the AP automatically determine the optimal power setting within
the defined power limits (i.e., up to the specified percentage/dBm value).
Interval
Specify the interval at which the Automatic power control feature adjusts the optimal power
setting.
Neighborhood scanning
Supported on: MSM410, HP 425, MSM430, MSM460, MSM466, MSM466-R, HP 517
Not configurable when Operating mode is set to Access point and Local mesh or Local mesh only.
These settings let you fine-tune the scanning operation used for RRM (“Radio Resource Management”
(page 182)) and IDS (“Intrusion detection system (IDS)” (page 196)).
Scan ratio
(Not configurable when Operating mode is set to Monitor.)
The percentage of time the radio will spend scanning channels other than the operating channel.
Dwell time
The amount of time (in milliseconds) that a radio remains on a channel while performing channel
scanning. The default value is 30 milliseconds. On the HP 517, the minimum value and default
setting is 32 milliseconds.
Set a value between 10 and 32 milliseconds when Operating mode is set to Access point only.
(Use a value of 30 milliseconds on the MSM410.)
Set a value between 10 and 1000 milliseconds when Operating mode is set to Monitor.
Scanning mode
• Passive: The AP listens to the channel to detect wireless traffic, but does not transmit any
probes. The AP will receive beacon frames and probe response frames, and use them to
identify neighbors. (When IDS is enabled, other frames are also received and sent to the IDS
system for analysis.) The key point is that no frames are transmitted. This is the default setting.
• Active: The AP uses probe request frames to speed up neighbor detection. Active scanning
only occurs on channels permitted by the regulatory domain. Transmission of probes is not
allowed on DFS channels, so no probes are sent on DFS channels even when this option is
selected.
Bands to scan
(Not configurable in Monitor mode. The All bands option is automatically used.)
(Not supported on the HP 425 and HP 517.)
• All bands: Scan both 802.11 bands (2.4 GHz and 5 GHz).
• Operating band only: Scan only the band in which the radio is currently operating.
Recommended settings for single radio APs:
• With IDS disabled, select Operating band only.
• With IDS enabled, select All bands.
