Release Notes

Parameter Description Range Default
determined by increasing the primary
channel number by 4. Example: 157+
represents 157 as the primary channel
and 161 as the secondary channel.
l num-: Entering a channel number with a
minus (-) sign selects a primary and
secondary channel for
40 MHz and 80 Mhz modes. The number
entered becomes the primary channel
and the secondary channel is
determined by decreasing the primary
channel number by 4. Example: 157-
represents 157 as the primary channel
and 153 as the secondary channel.
NOTE: 20 MHz clients are allowed to
associate when a primary and secondary
channel are configured; however, the client
will only use the primary channel.
channel-reuse
When you enable the channel reuse
feature, it can operate in either of the
following three modes; static, dynamic or
disable. (This feature is disabled by default.)
l Static mode: This mode of operation is a
coverage-based adaptation of the Clear
Channel Assessment (CCA) thresholds.
In the static mode of operation, the CCA
is adjusted according to the configured
transmission power level on the AP, so
as the AP transmit power decreases as
the CCA threshold increases, and vice
versa.
l Dynamic mode: In this mode, the Clear
Channel Assessment (CCA) thresholds
are based on channel loads, and take
into account the location of the
associated clients. When you set the
Channel Reuse This feature is
automatically enabled when the wireless
medium around the AP is busy greater
than half the time. When this mode is
enabled, the CCA threshold adjusts to
accommodate transmissions between
the AP its most distant associated client.
l Disable mode: This mode does not
support the tuning of the CCA Detect
Threshold.

channel-reuse-threshold
RX Sensitivity Tuning Based Channel Reuse
Threshold, in - dBm.
If the Rx Sensitivity Tuning Based Channel
reuse feature is set to static mode, this
parameter manually sets the AP’s Rx
sensitivity threshold (in -dBm). The AP will
filter out and ignore weak signals that are
below the channel threshold signal
strength.
If the value is set to zero, the feature will
automatically determine an appropriate
threshold.
