Parameter Description Range Default
40 MHz mode. 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
