Do not change the default setting for the radio that provides service to
802.11 clients only.
Dynamic Channel Selection – Click one of the following:
•Off – Disables DCS.
Monitor Mode – If traffic or noise levels exceed the configured DCS
thresholds, an alarm is triggered and an information log is generated.
Active Mode – If traffic or noise levels exceed the configured DCS
thresholds, an alarm is triggered and an information log is generated.
In addition, the Wireless AP will cease operating on the current
channel and ACS is employed to automatically select an alternate
channel for the Wireless AP to operate on.
DCS Noise Threshold – If DCS is enabled, type the noise
interference level, measured in dBm, after which ACS will scan for a
new operating channel for the Wireless AP if the threshold is
exceeded.
DCS Channel Occupancy Threshold – If DCS is enabled, type the
channel utilization level, measured as a percentage, after which ACS
will scan for a new operating channel for the Wireless AP if the
threshold is exceeded.
DCS Update Period – If DCS is enabled, type the time, measured in
minutes that determines the period during which the Wireless AP
averages the DCS Noise Threshold and DCS Channel Occupancy
Threshold measurements. If either one of these thresholds is
exceeded, then the Wireless AP will trigger ACS.
•Rx Diversity – Cick Best for the best signal from both antennas, or Left
or Right to choose either of the two diversity receiving antennas. The
default and recommended selection is Best. If only one antenna is
connected, use the corresponding Left or Right diversity setting. Do not
use Best if two identical antennas are not used.
Tx Diversity – Click Alternate for the best signal from both antennas, or
Left or Right to choose either of the two diversity receiving antennas. The
default selection is Alternate that maximizes performance for most
clients. However, some clients may behave oddly with Tx Diversity set to
Alternate. Under those circumstances, it is recommended to use either
Left or Right for Tx Diversity. If only one antenna is connected, use the
corresponding Left or Right diversity setting. Do not use Alternate if two
identical antennas are not used.
•Preamble – Click a preamble type for 11b-specific (CCK) rates: Short,
Long, or
Auto. The recommended value is Auto. Click Short if you are
sure that there is no pre-11b AP or a client in the vicinity of this AP. Click
Long if compatibility with pre-11b clients is required.
