Configuring Radio Channel Settings
Limiting the Power Level for Associated Client Devices
You can also limit the power level on client devices that associate to the wireless device. When a client
device associates to the wireless device, the wireless device sends the maximum power level setting to
the client.
Note Cisco AVVID documentation uses the term Dynamic Power Control (DTPC) to refer to limiting the
power level on associated client devices.
Beginning in privileged EXEC mode, follow these steps to specify a maximum allowed power setting on
all client devices that associate to the wireless device:
Use the no form of the client power command to disable the maximum power level for associated clients.
Note Aironet extensions must be enabled to limit the power level on associated client devices. Aironet
extensions are enabled by default.
Configuring Radio Channel Settings
The default channel setting for the wireless device radios is least congested; at startup, the wireless
device scans for and selects the least-congested channel. For the most consistent performance after a site
survey, however, we recommend that you assign a static channel setting for each access point. The
channel settings on the wireless device correspond to the frequencies available in your regulatory
domain. See the access point hardware installation guide for the frequencies allowed in your domain.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface dot11radio {0 | 1slot/port} Enter interface configuration mode for the radio interface.
The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
The 2.4-GHz 802.11n radio is 0, and the 5-GHz 802.11n radio
is 1.
Step 3
power client
These options are available for both
802.11n 2.4-GHz and 5-GHz clients
(in dBm):
{-127 to 127 | local | maximum}
Set the power level allowed on client devices that associate to
the wireless device. You can:
• Set any power level value in dBm from -127 to 127
• Set the power level to local, to set the client power level to
that of the access point.
• Set the power level to maximum, to set the client power to
the allowed maximum.
Note The settings allowed in your regulatory domain might
differ from the settings listed here.
Step 4
end Return to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
