Radio and Antenna Configuration
4-24 Configuring the Enterasys Wireless Standalone 802.11n AP
Dynamic Radio Management
Dynamic Channel Selection (DCS) Select the DCS mode. DCS allows the AP to monitor traffic and
noise levels on the channel on which the AP is currently operating.
DCS can operate in two modes or be disabled:
• Monitor Mode – When DCS is enabled in monitor mode and
traffic or noise levels exceed the configured DCS thresholds,
an alarm is triggered and an information log is generated. The
DCS monitor alarm is used for evaluating the RF environment
of your deployed
APs.
• Active Mode – When DCS is enabled in active mode and
traffic or noise levels exceed the configured DCS thresholds,
an alarm is triggered and an information log is generated. In
addition, the
AP will cease operating on the current channel
and ACS is employed to automatically select an alternate
channel for the
AP to operate on. DCS will not trigger channel
changes on neighboring APs.
• Off (default)— Disables DCS.
DCS Noise Threshold Enter the noise interface threshold, measured in dBm. DCS will
scan for a new operating channel for the AP if this threshold is
exceeded. The default is -80 dBm.
DCS Channel Occupancy
Threshold
Enter the channel utilization level, measured as a percentage.
DCS will scan for a new operating channel for the AP if the
threshold is exceeded. The default is 100%.
DCS Update Period Enter the time, measured in minutes that determines the period
during which the
AP averages the DCS Noise Threshold and DCS
Channel Occupancy Threshold measurements. If either one of
these thresholds is exceeded, then the AP will trigger DCS. The
default is 5 minutes.
