Auto Tune Tab; Service Profile Selection Tab - Nortel 2350 Reference Manual

Auto Tune Tab

The Auto Tune tab lists settings for Auto-RF:
• Tune Channel—Automatically configures and tunes the channel. This feature is enabled by default.
Note. Auto-RF 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 Auto-RF of channels on the radio profile the radio is in,
and statically configure the channel.
• Tune Transmit Power—Automatically configures and tunes the power. This feature is disabled by default.
• Channel Tuning Interval—Interval at which RF Auto-Tuning decides whether to change the channels on radios in a
radio profile.
At the end of each interval, WSS Software 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. Nortel
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.
• Tx. Power Tuning Interval—Interval at which RF Auto-Tuning decides whether to change the power level on
radios. You can specify from 1 to 65535 seconds. The default is 300 seconds.
• Power Ramp Interval—Interval at which power is increased or decreased, in 1 dBm increments, on radios until the
optimum power level calculated by Auto-RF is reached. After each power ramp interval, the radio increases or
decreases the power by another 1 dB until the radio reaches the power level selected by Auto-RF.
• Channel Tuning Holddown—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.
You can specify from 0 to 65535 seconds. The default channel interval is 900 seconds.
• Tx. Power Backoff Timer—Interval at which radios reduce power after temporarily increasing the power to
maintain the minimum data rate for an associated client.
At the end of each power-backoff interval, radios that temporarily increased their power reduce it by
1 dBm. The power backoff continues in 1 dBm increments after each interval until the power returns to
expected setting.
You can specify from 0 to 65535 seconds. The default is 10 seconds.

Service Profile Selection Tab

The Profile Selection tab lists the service profiles to which the radio profile is mapped. The radios managed by the radio
profile provide wireless service for the service profiles' SSIDs.
To map the radio profile to a service profile, select the service profile in the Available Service Profiles list. Click Add to
move the profile name to the Current Service Profiles list.
