Overriding Dynamic RRM

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 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:
•
•
While you can specify a global default transmit power parameter for each network type that applies to
Note
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
Note
Wireless Control System Configuration Guide for instructions.
OL-8335-02
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
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.)
