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:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface dot11radio {0 | 1} 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.
Step3 power client
These options are available for
802.11b, 2.4-GHz clients (in mW):
{local | 1 | 5 | 20 | 30 | 50 | 100 |
maximum}
These options are available for
802.11g, 2.4-GHz clients (in mW):
{local | 1 | 5 | 10 | 20 | 30 | 50 | 100 |
maximum}
These options are available for 5-GHz
clients (in mW):
{local | 5 | 10 | 20 | 40 | maximum }
If your access point contains an
AIR-RM21A 5-GHz radio module,
these power options are available for
5-GHz clients (in dBm):
{local | -1 | 2 | 5 | 8 | 11 | 14 | 16 | 17 |
20 | maximum }
These options are available for
802.11n 2.4-GHz clients (in dBm):
{local |-1 | 2 | 5 | 8 | 11 | 14 | 17 | 20
|maximum }
These options are available for
802.11n 5-GHz clients (in dBm):
{local | 2 | 5 | 8 | 11 | 14 | 17 |
|maximum }
Set the maximum power level allowed on client devices that
associate to the wireless device.
Setting the power level to local sets the client power level to
that of the access point.
Setting the power level to maximum sets the client power to
the allowed maximum.
Note The settings allowed in your regulatory domain might
differ from the settings listed here.
