From the top-left corner, click the menu icon and choose .
|
Step 2
|
Click the Wireless tab.
|
Step 3
|
From the left hierarchy tree, choose Global.
|
Step 4
|
Click RF Profiles.
|
Step 5
|
In the Wireless Radio Frequency Profile area, hover your cursor over Add and choose AI RF Profile.
|
Step 6
|

|
Step 7
|
In the Radio Frequency Settings area of Basic Settings, check the 2.4 GHz, 5 GHz, or 6 GHz check box.
The RF bands are checked by default. If you uncheck a band, Cisco DNA Center disables the Admin status of the corresponding RF profile.
Note
|
Cisco Catalyst 9800 Series Wireless Controllers running Cisco IOS XE Release 17.9.1 and later support the AI RF profile for the 6 GHz band.
|
|
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 time zone of the building. You must configure a time zone for the respective building under
network settings.
|
|
Step 9
|
In the Busy Hour Sensitivity area, click the Low, Medium, or High radio button to define the threshold of the 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, 5 GHz, or 6 GHz columns to enable or disable RF settings for the corresponding bands.
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 the 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 performance and interference.
Note
|
-
When you disable the 2.4 GHz band for FRA, it automatically disables the 5 GHz band for FRA, and conversely.
-
When you disable the 5 GHz band for DCA, it disables the 2.4 GHz band for FRA and the 5 GHz band for FRA and DBS.
-
You can individually enable the 2.4 GHz band for DCA and TPC, and the 5 GHz band for DCA, TPC, and DBS. For the 5 GHz band, if DCA and DBS are disabled and you enable DBS, DCA is also enabled.
-
You can enable or disable the 6 GHz band together for DCA and DBS RF settings. You can individually enable the 6 GHz band for TPC.
-
FRA is not supported for the 6 GHz band.
