Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

RF Profile

RF Profile

RF profile contains the common radio configuration for the APs. RF profiles are applied to all APs that belong to an AP group, where all APs in that group have the same profile settings. RF Profiles allows you to tune groups of APs that share a common coverage zone together and selectively change how RRM will operate the APs within that coverage zone.

RF profile has two default profiles: 802.11a and 802.11b. All the configurations, global and RF, are available now only as part of RF profile.

On the Configuration > Tags & Profiles > RF page, click Add to configure the following:

ClosedGeneral
  1. In the General tab, enter a name for the RF profile.
  2. Choose the appropriate radio band.
  3. To enable the profile, set the status as Enable.
  4. In the Description field, enter the RF profile description.
  5. Click Apply to Device.
Closed802.11
  1. In the 802.11 tab, choose the required operational rates.

  2. Select the required 802.11n MCS Rates by checking the corresponding check boxes.

  3. Click Apply to Device.
ClosedRRM
  1. In the RRM > General tab, in the Interference field, enter the foreign interference threshold between 0 and 100 percent. The default is 10.
  2. In the Clients field, enter the client threshold between 1 and 75 clients. The default is 12.
  3. In the Noise field, enter the foreign noise threshold between –127 and 0 dBm. The default is –70.
  4. In the Utilization percentage field, enter the RF utilization threshold between 0 and 100 percent. The default is 80.
  5. In the RRM > Coverage tab, under Coverage Hole Detection, in the Minimum Client Level field, enter the client level.
  6. In the Data RSSI Threshold field, enter the actual value in dBm. Value ranges from -60 to -90 dBm and the default value is –80 dBm.
  7. In the Voice RSSI Threshold field, enter the actual value in dBm. Value ranges from -60 to -90 dBm and the default value is –75.
  8. In the Exception Level field, enter the maximum desired percentage of clients on an AP’s radio operating below the desired coverage threshold. Value ranges from 0 to 100% and the default value is 25%.
  9. In the RRM > TPC tab, under the Transmit Power Control section, in the Maximum Power Level field, enter the power level assignment on this radio. If you configure maximum transmit power, RRM does not allow any access point attached to the device to exceed this transmit power level (whether the power is set by RRM TPC or by coverage hole detection).
  10. In the Minimum Power Level field, enter the minimum power level assignment on this radio.
  11. In the Power Threshold V1 field, enter the cutoff signal level used by RRM when determining whether to reduce an access point’s power.
  12. In the RRM > DCA tab, under the Dynamic Channel Assignment section, check the Avoid Foreign AP Interference check box to cause the controller’s RRM algorithms to consider 802.11 traffic from foreign access points (those not included in your wireless network) when assigning channels to lightweight access points, or unselect it to disable this feature. For example, RRM may adjust the channel assignment to have access points avoid channels close to foreign access points. The default value is selected.
  13. Choose the appropriate channel width.
  14. In the DCA Channels field, you get to view the channels that are currently selected. To choose a channel, select the appropriate check box. Extended UNII-2 channels in the 802.11a/n/ac band do not appear in the channel list: 100, 104, 108, 112, 116, 132, 136, and 140. To include these channels in the channel list, select the Extended UNII-2 Channels check box.
  15. In the High Speed Roam section, enable the High Speed Roam mode.
  16. In the Neighbor Timeout field, enter the timeout factor value. The valid range is 5 minutes to 60 minutes with the default value being 5 minutes.
  17. Choose one of the options for Client Network Preference:
    • Connectivity
    • Throughput
    • Default
  18. Click Apply to Device.
