You can specify from 0 to 65535 seconds. The default is 10 seconds.
5 To enable automatic configuration and tuning of the channel, select Yes
next to Tune Channel. This feature is enabled by default.
6 To change the interval at which RF Auto-Tuning decides whether to
change the channels on radios in a radio profile, change the value in the
Channel Tuning Interval box.
At the end of each interval, MSS processes the results of the RF scans
performed during the previous interval, and changes radio channels if
needed.
You can specify from 0 to 65535 seconds. The default channel interval is
3600 seconds. 3com recommends that you use an interval of at least 300
seconds (5 minutes). If you set the interval to 0, RF Auto-Tuning does not
reevaluate the channel at regular intervals. However, RF Auto-Tuning can
still change the channel in response to RF anomalies.
7 To change 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, change the value in the Channel Tuning Holddown
box.
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.
You can specify from 0 to 65535 seconds. The default channel interval is
900 seconds.
