Step 1
|
Click the menu icon () and choose .
|
Step 2
|
Click the Wireless tab.
|
Step 3
|
In the left pane, click the Global site.
|
Step 4
|
In the Wireless Radio Frequency Profile area, from the Add drop-down list, choose AI RF Profile.
The Create AI Radio Frequency Profile window appears.
|
Step 5
|
In the Profile Name field, enter the RF profile name.
|
Step 6
|
Expand Basic Settings.
|
Step 7
|
In the Radio Frequency Settings area, check the 2.4 GHz or 5 GHz check box.
The radio frequencies are checked by default. If you uncheck a radio frequency, the RF settings are disabled for that radio
frequency.
|
Step 8
|
In the Busy Hours area, define the start and end time of the site time zone.
Note
|
Busy hours are dependent upon the timezone of building. You must configure a timezone under network settings for the respective
building.
|
|
Step 9
|
In the Busy Hour Sensitivity area, click the Low, Medium, or High radio button to define the threshold of Radio Resource Management (RRM) sensitivity for the busy hours interval.
|
Step 10
|
In the Enable RF Settings area, click the toggle buttons under the 2.4 GHz or 5 GHz columns to enable or disable the radio band for the respective RF setting.
The supported RF settings are:
-
Flexible Radio Assignment (FRA): FRA optimizes the radio coverage per band and determines the best role assignment for redundant radios.
-
Dynamic Channel Assignment (DCA): DCA dynamically manages channel assignment for an RF group and evaluates the assignments on a per-AP radio basis.
-
Transmit Power Control (TPC): TPC manages and transmits power for APs. It also maximizes the SNR during the reduction in interference.
-
Dynamic Bandwidth Selection (DBS): DBS monitors and adjusts the channel width to balance the performance and interference.
Note
|
-
When you disable the 2.4-GHz radio band for FRA, it automatically disables the 5-GHz radio band for FRA, and vice versa.
-
When you disable the 5-GHz radio band for DCA, it disables the 2.4-GHz radio band for FRA and the 5-GHz radio band for FRA
and DBS.
-
You can individually enable the 2.4-GHz radio band for DCA and TPC; and the 5-GHz radio band for DCA, TPC, and DBS.
|
|
Step 11
|
Expand Advanced and click the 2.4 GHz toggle button.
|
Step 12
|
In the DCA Channel area, check the Select All check box to select DCA channels 1, 6, and 11. Alternatively, check the individual check boxes next to the channel numbers.
|
Step 13
|
In the Advanced Options area, check the Select All check box to select all the DCA channels.
|
Step 14
|
Click Show Advanced to select the remaining channel numbers.
|
Step 15
|
Check the check box next to the individual channel numbers. The channel numbers that are available for the profile are 2, 3, 4, 5, 7, 8, 9, 10, 12, 13, and 14.
|
Step 16
|
Use the Supported Data Rate slider to set the rates at which data can be transmitted between an AP and a client. The available data rates are 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54.
|
Step 17
|
In the Mandatory Data Rates area, check the check box next to the individual data rates. You can choose up to two data rates. The available data rates
are 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54.
|
Step 18
|
Check the Enable 802.11b data rates check box to enable the 802.11b data rates. This action also enables the 802.11b supported data rate check box in the Mandatory Data Rates area.
|
Step 19
|
In the Tx Power Configuration area, set the following:
-
Power Level: Determines whether the power of an AP needs to be reduced. Reducing the power of an AP helps mitigate co-channel interference.
-
Power Threshold: Is the cutoff signal level used by RRM to determine whether to reduce the power of an AP.
-
RX SOP: Receiver Start of Packet Detection Threshold (RX SOP) determines the Wi-Fi signal level, in dBm, at which an AP's radio
demodulates and decodes a packet.
|
Step 20
|
Use the Power Level slider to set the minimum and maximum power level. The range is from -10 to 30 dBm and the default is -10 dBm.
|
Step 21
|
Use the Power Threshold slider to increase and decrease the power value, which causes the AP to operate at higher or lower transmit power rates.
The range is from -50 dBm to 80 dBm and the default threshold is -70 dBm.
|
Step 22
|
From the RX SOP drop-down list, choose High, Medium, Low, or Auto threshold values for each 802.11 band.
|
Step 23
|
In the Advanced area, click the 5 GHz toggle button.
|
Step 24
|
Use the DBS Max Width slider to set the channel width of the AI RF profile.
The available channel width options are 20 MHz, 40 MHz, 80 MHz, or 160 MHz.
The Auto Channels Logic area displays the color-coded channel logics for the channel widths.
You can select DBS Max Width only when DBS is enabled.
When you disable the DBS, Cisco DNA Center allows you to select channel width.
|
Step 25
|
Set the DCA channels to manage the following channel assignments:
-
UNII-1 36-48: The channels available for UNII-1band are 36, 40, 44, and 48.
-
UNII-2 52-144: The channels available for UNII-2band are 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, and 144.
-
UNII-3 149-165: The channels available for UNII-3 band are 149, 153, 157, 161, and 165.
Note
|
You must configure the channels globally on the Cisco Wireless Controller.
|
|
Step 26
|
Check the Select All check box to include all DCA channels, or check an individual check box to select an individual DCA channel.
|
Step 27
|
Click Show Advanced to select the remaining DCA channel numbers.
|
Step 28
|
Check the UNII-1 36-48 check box to include all channels, or check an individual check box.
|
Step 29
|
Check the UNII-2 52-144 check box to include all channels, or check an individual check box.
|
Step 30
|
Check the UNII-3 149-165 check box to include all channels, or check an individual check box.
|
Step 31
|
Use the Supported Data Rate slider to set the rates at which data can be transmitted between an AP and a client. The available data rates are 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54.
|
Step 32
|
In the Tx Power Configuration area, set the Power Level, Power Threshold, and RX SOP.
|
Step 33
|
Use the Power Level slider to set the minimum and maximum power level. The range is from -10 to 30 dBm and the default is -10 dBm.
|
Step 34
|
Use the Power Threshold slider to increase and decrease the power value, which causes the AP to operate at higher or lower transmit power rates.
The range is from -50 dBm to 80 dBm and the default threshold is -70 dBm.
|
Step 35
|
From the RX SOP drop-down list, choose High, Medium, Low, or Auto threshold values.
