Chapter 9 Configuring Radio Resource Management
Overriding Dynamic RRM
Step 3 Perform one of the following:
•To have RRM automatically set the transmit power for all 802.11a or 802.11b/g radios at periodic intervals, enter one of these commands:
–config 802.11a txPower global auto
–config 802.11b txPower global auto
•To have RRM automatically reset the transmit power for all 802.11a or 802.11b/g radios one time, enter one of these commands:
–config 802.11a txPower global once
–config 802.11b txPower global once
Step 4 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.)
Overriding Dynamic RRM

Note
In some deployments, it is desirable to statically assign channel and transmit power settings to the access points instead of relying on the dynamic RRM algorithms provided by Cisco. Typically, this is true in challenging RF environments and
If you choose to statically assign channels and power levels to your access points and/or to disable dynamic channel and power assignment, you should still use automatic RF grouping to avoid spurious rogue device events.
You can disable dynamic channel and power assignment globally for a controller, or you can leave dynamic channel and power assignment enabled and statically configure specific access point radios with a channel and power setting. Follow the instructions in one of the following sections:
•Statically Assigning Channel and Transmit Power Settings to Access Point Radios, page
•Disabling Dynamic Channel and Power Assignment Globally for a Controller, page
While you can specify a global default transmit power parameter for each network type that applies to all the access point radios on a controller, you must set the channel for each access point radio when you disable dynamic channel assignment. You may also want to set the transmit power for each access point instead of leaving the global transmit power in effect.
You can also override dynamic RRM using the Cisco Wireless Control System (WCS). Refer to the Cisco Wireless Control System Configuration Guide for instructions.
