Parameter Description Range Default
beacon-period Time, in milliseconds, between successive
beacon transmissions. The beacon advertises the
AP’s presence, identity, and radio characteristics
to wireless clients. 60 (minimum) 100
mil-
liseconds
beacon-regulate Enabling this setting introduces randomness in the
beacon generation so that multiple APs on the
same channel do not send beacons at the same
time, which causes collisions over the air. — disabled
cap-reg-eirp <cap-reg-eirp> Work around a known issue on Cisco 7921G
telephones by specifying a cap for a radio’s
maximum equivalent isotropic radiated power
(EIRP). When you enable this parameter, even if
the regulatory approved maximum for a given
channel is higher than this EIRP cap, the AP radio
using this profile will advertise only this capped
maximum EIRP in its radio beacons. 1–31 dBm.
cell-size-reduction <cell-
size-reduction>
The cell size reduction feature allows you manage
dense deployments and to increase overall system
performance and capacity by shrinking an AP’s
receive coverage area, thereby minimizing co-
channel interference and optimizing channel
reuse. This value should only be changed if the
network is experiencing performance issues. The
possible range of values for this feature is 0-55 dB.
The default 0 dB reduction allows the radio to
retain its current default Rx sensitivity value.
Values from 1 dB - 55 dB reduce the power level
that the radio can hear by that amount. If you con-
figure this feature to use a non-default value, you
must also reduce the radio’s transmission (Tx)
power to match its new received (Rx) power level.
Failure to match a device’s Tx power level to its Rx
power level can result in a configuration that
allows the radio to send messages to a device that
it cannot hear.

Name of an existing radio profile from which

csa
Channel Switch Announcement (CSA), as defined
by IEEE 802.11h, allows an AP to announce that it
is switching to a new channel before it begins
transmitting on that channel.
Clients must support CSA in order to track the
channel change without experiencing disruption. — disabled
csa-count
Number of CSA announcements that are sent
before the AP begins transmitting on the new
channel. 1-16 4
