Chapter 9 Configuring Radio Resource Management
Overriding Dynamic RRM
Using the CLI to Statically Assign Channel and Transmit Power Settings
Follow these steps to statically assign channel and/or power settings on a per access point radio basis using the CLI.
Step 1 Enter one of these commands to disable the 802.11a or 802.11b/g network:
•config 802.11a disable
•config 802.11b disable
Step 2 To specify the channel that a particular access point is to use, enter one of these commands:
•config 802.11a channel Cisco_AP channel
•config 802.11b channel Cisco_AP channel
Example: To configure 802.11a channel 36 as the default channel on AP1, enter this command: config 802.11a channel AP1 36.
Step 3 To specify the transmit power level that a particular access point is to use, enter one of these commands:
•config 802.11a txPower Cisco_AP power_level
•config 802.11b txPower Cisco_AP power_level
Example: To set the transmit power for 802.11a AP1 to power level 2, enter this command:
config 802.11a txPower AP1 2.
The transmit power level is assigned an integer value instead of a value in mW or dBm. The integer corresponds to a power level that varies depending on the regulatory domain in which the access points are deployed. The number of available power levels varies based on the access point model. However, power level 1 is always the maximum power level allowed per country code setting, with each successive power level representing 50% of the previous power level. For example, 1 = maximum power level in a particular regulatory domain, 2 = 50% power, 3 = 25% power, 4 = 12.5% power, and so on.
Note Refer to the Hardware Installation Guide for your access point for the maximum transmit power levels supported per regulatory domain. Also, refer to the data sheet for your access point for the number of power levels supported.
Step 4 Repeat Step 2 and Step 3 for each access point radio for which you want to assign a static channel and power level.
Step 5 Enter one of these commands to enable the 802.11a or 802.11b/g network:
•config 802.11a enable
•config 802.11b enable (To enable the 802.11g network, enter config 802.11b 11gSupport enable after the config 802.11b enable command.)
