Overriding RRM
In some deployments, it is desirable to statically assign channel and transmit power settings to the access
points instead of relying on the RRM algorithms provided by Cisco. Typically, this is true in challenging
RF environments and non-standard deployments but not the more typical carpeted offices.
Note
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 11-26
•
Disabling Dynamic Channel and Power Assignment Globally for a Controller, page 11-33
Note
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.
