NN47250-100 (Version 02.51)
Even when RF Auto-Tuning for channels is enabled, WSS Software does not change the channel on radios that have
active client sessions, unless you use the no-client option.
RF Auto-Tuning of channels on 802.11a radios uses only the bottom eight channels in the band (36, 40, 44, 48, 52, 56,
60, and 64). To use a higher channel number, you must disable RF Auto-Tuning of channels on the radio profile the
radio is in, and use the set ap radio channel command to statically configure the channel.
Examples
The following command disables dynamic channel tuning for radios in the rp2 radio profile:
WSS# set radio-profile rp2 auto-tune channel-config disable
success: change accepted.

set radio-profile auto-tune channel-holddown
Sets the minimum number of seconds a radio in a radio profile must remain at its current channel assignment before
RF Auto-Tuning can change the channel. The channel holddown provides additional stability to the network by
preventing the radio from changing channels too rapidly in response to spurious RF anomalies such as short-duration
channel interference.
Syntax
set radio-profile name auto-tune channel-holddown holddown
Defaults
The default RF Auto-Tuning channel holddown is 900 seconds.
Access
Enabled.
History
Introduced in WSS Software Version 3.0.
Usage
The channel holddown applies even if RF anomalies occur that normally cause an immediate
channel change.
Examples
The following command changes the channel holddown for radios in radio profile rp2 to 600
seconds:
WSS# set radio-profile rp2 auto-tune channel-holddown 600
success: change accepted.
