Configuring Radio Transmit Power
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.
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.
Step 3
power client
These options are available for
802.11b, 2.4-GHz clients (in mW):
{ 1 | 5 | 20 | 30 | 50 | 100 | local |
maximum}
These options are available for
802.11g, 2.4-GHz clients (in mW):
{ 1 | 5 | 10 | 20 | 30 | 50 | 100 | local |
maximum}
These options are available for
5-GHz clients (in mW):
{ 5 | 10 | 20 | 40 | local | maximum }
If your access point contains an
AIR-RM21A 5-GHz radio module,
these power options are available for
5-GHz clients (in dBm):
{ -1 | 2 | 5 | 8 | 11 | 14 | 16 | 17 | 20 |
local | maximum }
Set the maximum power level allowed on client devices that
associate to the wireless device.
Note The settings allowed in your regulatory domain might
differ from the settings listed here.
The local parameter tells the client to set its transmitter power
to match the access point’s local power setting. This limits the
client to the higher OFDM or CCK power set on the access
point.
Note The maximum transmit power depends on your
regulatory domain and the antenna gain for your access
point or bridge. This command requires the client radio
to be turned on and enabled to determine the valid
power settings configured on your access point.
Step 4
end Return to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
