Configuring Dynamic RRM
Client Min Exception
Level (1 to 75)
The minimum number of clients on an access point with a
signal-to-noise ratio (SNR) below the Coverage threshold. This
threshold works in conjunction with the Coverage and Coverage
Exception Level thresholds. A coverage exception is alerted if the
Coverage Exception Level percentage of clients (25%) and the Client
Min Exception Level number of clients (3) fall below the Coverage
threshold (12 dB). In this example, a coverage alarm would be
generated if at least 25% and a minimum of 3 clients have an SNR value
below 12 dB (802.11b/g) or 16 dB (802.11a).
Default: 3
Noise/Interference/Rogue Monitoring Channels
Channel List The set of channels that the access point uses for RRM scanning.
Options:All Channels, Country Channels, or DCA Channels
Default: Country Channels
Channel List Description
All
Channels
RRM channel scanning occurs on all channels supported
by the selected radio, which includes channels not
allowed in the country of operation.
Country
Channels
RRM channel scanning occurs only on the data channels
in the country of operation.
DCA
Channels
RRM channel scanning occurs only on the channel set
used by the Dynamic Channel Allocation (DCA)
algorithm, which typically includes all the
non-overlapping channels allowed in the country of
operation.
Monitor Intervals
Noise Measurement How frequently the access point measures noise and interference.
Range: 60 to 3600 seconds
Default: 180 seconds
Load Measurement How frequently the access point measures 802.11 traffic.
Range: 60 to 3600 seconds
Default: 60 seconds
