Configure transmit power control


Configure transmit power (GUI)

Configure transmit power settings for wireless APs.

Procedure

1.

Choose Configuration > Radio Configurations > RRM .

2.

On the 6 GHz Band , 5 GHz Band , or 2.4 GHz Band tab, click the TPC tab.

3.

Choose one of these dynamic transmit power assignment modes:

  • Automatic (default): The transmit power is periodically updated for all APs that permit this operation.
  • On Demand: The transmit power is updated on demand. If you choose this option, you get to view the Invoke Power Update Once . Click Invoke Power Update Once to apply the RRM data successfully.
  • Fixed: No dynamic transmit power assignments occur and values are set to their global default.
4.

Enter the maximum and minimum power level assignment on this radio. If you configure maximum transmit power, RRM does not allow any AP attached to the device to exceed this transmit power level. This applies whether the power is set by RRM TPC or by coverage hole detection.

For example, if you configure a maximum transmit power of 11 dBm, then no AP would transmit above 11 dBm, unless the AP is configured manually. The range is from –10 dBm to 30 dBm.

5.

In the Power Threshold field, enter the cutoff signal level used by RRM when determining whether to reduce an access point’s power.

The default value for this parameter varies depending on the TPC version you choose. For TPCv1, the default value is –70 dBm, and for TPCv2, the default value is –67 dBm. The default value can be changed when APs are transmitting at higher (or lower) than desired power levels. The range is from –80 to –50 dBm.

Increasing this value (between –65 and –50 dBm) causes the APs to operate at higher transmit power rates. Decreasing the value has the opposite effect. In applications with a dense population of APs, it may be useful to decrease the threshold to –80 or –75 dBm in order to reduce the number of BSSIDs (APs) and beacons seen by the wireless clients. Some wireless clients might have difficulty processing a large number of BSSIDs or a high beacon rate and might exhibit problematic behavior with the default threshold.

6.

Click Apply .

Transmit power settings are updated according to your configuration.


Configure Tx-power control threshold (CLI)

Set the Tx-power control threshold to define the minimum received signal strength at which the device adjusts its transmit power.

Procedure

1.

Enter global configuration mode.

Example:

Device# configure terminal
2.

Configure the Tx-power control threshold used by RRM for auto power assignment.

Example:

Device(config)# ap dot11 {24ghz | 5ghz | 6ghz} rrm tpc-threshold threshold_value

The range is from –80 dBm to –50 dBm.

3.

Return to privileged EXEC mode.

Example:

Device(config)# end

You can also press Ctrl-Z to exit global configuration mode.

The Tx-power control threshold is updated, enabling the device to adjust its transmit power according to the specified threshold.

Device# configure terminal
Device(config)# ap dot11 24ghz rrm tpc-threshold -60
Device(config)# end

Configure the Tx-power level (CLI)

Set the transmit power level of the wireless AP to improve wireless coverage and signal strength.

Procedure

1.

Enter global configuration mode.

Example:

Device# configure terminal
2.

Configure the 802.11 Tx-power level.

Example:

Device(config)# ap dot11 {24ghz | 5ghz} rrm txpower {trans_power_level | auto | max | min | once}
The Tx-power parameters are:
  • trans_power_level: Sets the transmit power level.

  • auto: Enables auto-RF.

  • max: Configures the maximum auto-RF Tx-power.

  • min: Configures the minimum auto-RF Tx-power.

  • once: Enables one-time auto-RF.

3.

Configure the 802.11 6-GHz Tx-power level.

Example:

Device(config)# ap dot11 6ghz rrm txpower trans_power_level auto
The Tx-power parameters are:
  • trans_power_level: Sets the transmit power level. The range is 1 to 5.

  • auto: Enables auto-RF.

Note

The 6-GHz band uses constant-PSD instead of constant-EIRP, which allows you to transmit at higher power as the channel width increases. The system derives the power levels based on the configured channel width. At higher power levels between 1 and 3, these power values exceed the limit for legacy rate frames, such as beacon frames. The beacon power does not change at higher levels in the 6-GHz band, unlike in the 2.4-GHz and 5-GHz bands.

4.

end

Example:

Device(config)# end

Return to privileged EXEC mode.


Configure 802.11 RRM parameters


Configure advanced 802.11 channel assignment parameters (GUI)

Configure the RRM settings to optimize channel assignment for 802.11 wireless networks.

Procedure

1.

Choose Configuration > Radio Configurations > RRM .

2.

In the DCA tab, complete these details:

  1. Select a Channel Assignment Mode to specify the DCA mode:

    • Automatic (default): Causes the device to periodically evaluate and, if necessary, update the channel assignment for all joined APs.

    • Freeze: Causes the device to evaluate and update the channel assignment for all joined APs. If you choose this option, you get to view the Invoke Channel Update Once. Click Invoke Channel Update Once to apply the RRM data successfully.

    • Off: Turns off DCA and sets all AP radios to the first channel of the band, which is the default value. If you choose this option, you must manually assign channels on all radios.

  2. From the Interval drop-down list, choose the interval that tells how often the DCA algorithm is allowed to run. The default interval is 10 minutes.

  3. From the Anchortime drop-down list, choose a number to specify the time of day when the DCA algorithm must start. The options are numbers between 0 and 23 (inclusive) representing the hour of the day from 12:00 a.m. to 11:00 p.m.

  4. Check the Avoid Foreign AP Interference check box to cause the device’s RRM algorithms to consider 802.11 traffic from foreign APs (those not included in your wireless network) when assigning channels to lightweight APs, or uncheck it to disable this feature. For example, RRM may adjust the channel assignment to have APs avoid channels close to foreign APs. By default, this feature is in enabled state.

  5. Check the Avoid Cisco AP Load check box to cause the device’s RRM algorithms to consider 802.11 traffic from Cisco lightweight APs in your wireless network when assigning channels. For example, RRM can assign better reuse patterns to APs that carry a heavier traffic load. By default, this feature is in disabled state.

  6. Check the Avoid Non-802.11a Noise check box to cause the device’s RRM algorithms to consider noise (non-802.11 traffic) in the channel when assigning channels to lightweight APs. For example, RRM may have APs avoid channels with significant interference from non-AP sources, such as microwave ovens. By default, this feature is in enabled state.

  7. Check the Avoid Persistent Non-Wi-Fi Interference check box to enable the device to take into account persistent non-Wi-Fi interference in DCA calculations. A persistent interfering device is any device from the following categories, which has been seen in the past 7 days - Microwave Oven, Video Camera, Canopy, WiMax Mobile, WiMax Fixed, Exalt Bridge. With Avoid Persistent Non-Wi-Fi Interference enabled, if a Microwave Oven is detected, that interference from the Microwave Oven is taken into account in the DCA calculations for the next 7 days. After 7 days, if the interfering device is not detected anymore, it is no longer considered in the DCA calculations.

  8. From the DCA Channel Sensitivity drop-down list, choose one of the following options to specify how sensitive the DCA algorithm is to environmental changes such as signal, load, noise, and interference when determining whether to change channels:

    • Low: The DCA algorithm is not particularly sensitive to environmental changes. The DCA threshold is 30 dB.

    • Medium (default): The DCA algorithm is moderately sensitive to environmental changes. The DCA threshold is 15 dB.

    • High: The DCA algorithm is highly sensitive to environmental changes. The DCA threshold is 5 dB.

  9. Set the Channel Width as required. You can choose the RF channel width as 20 MHz, 40 MHz, 80 MHz, 160 MHz, or Best. This is applicable only for 802.11a/n/ac (5 GHz) radio.

3.

The Auto-RF Channel List section shows the channels that are currently selected. To select a channel, check the corresponding check box.

Note

If you disable the serving radio channel of the root AP from the Auto-RF Channel List, you will not be able to view the neighboring APs in the root APs.

4.

In the Event Driven RRM section, check the EDRRM check box to run RRM when CleanAir-enabled AP detects a significant level of interference. If enabled, set the sensitivity threshold level at which the RRM is invoked, enter the custom threshold, and check the Rogue Contribution check box to enter the rogue duty-cycle.

5.
