Configuring Dual 5 GHz Radio Bands on an IAP

Aruba Central (on-premises) provides an option to retrieve the radio numbers of Instant Access Point (IAP) through the APIsApplication Programming Interface. Refers to a set of functions, procedures, protocols, and tools that enable users to build application software.. It also provides an option to filter IAP details using radio numbers in the IAP monitoring dashboard.

To retrieve the radio numbers through API, complete the following steps:

1. In the Account Home page, click API Gateway.

   The API Gateway page is displayed.

2. Click the APIs tab.

   The token key is valid only for 2 hours from the time it was generated.

3. In the All Published APIs window, click the urlUniform Resource Locator. URL is a global address used for locating web resources on the Internet. link listed under the Documentation column.

   The Central Network Management APIs page is displayed.

4. On the left navigation pane, select Monitoring from the URL drop-down list.

5. Click API Reference > AP.

   The following APIs allow you to retrieve the radio number for the total number of clients connected:

   Table 1: APIs to Get Radio Number in APs

   API	Description
   [GET]/monitoring/v1/aps/{serial}/neighbouring_clients	Allows you to filter data of neighbouring clients for a specific radio number in a given time period. When there is no radio number entered in the radio_number field, the API filters the data of neighbouring clients for both radio 0 and radio 1. It is mandatory to provide the serial number of the AP to get the data of neighboring clients for a specific radio number.
   [GET]/monitoring/v1/aps/rf_summary	Retrieves information on RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. summary such as channel utilization and noise floor in positive, errors, drops for a given time period. This API can also be used to filter RF health statistics for a specific radio number in a given time period. When there is no radio number entered in the radio_number field, the API filters the RF health statistics for both radio 0 and radio 1. It is mandatory to provide the serial number of the AP to get the RF health statistics for a specific radio number.
   [GET]/monitoring/v1/aps/bandwith_usage	This API can also be used to filter out bandwidth usage data for a specific radio number in a given time period. When there is no radio number entered in the radio_number field, the API filters the bandwidth usage for both radio 0 and radio 1. It is mandatory to provide the serial number of the AP to get the bandwidth usage for a specific radio number.

6. On the left navigation pane, click API Reference > Client.

   The following APIs allow you to retrieve the radio number for the total number of clients connected:

   Table 2: APIs to Get Radio Number in Connected Clients

   API	Description
   [GET]/monitoring/v1/clients/count	This API is used to filter out the data for connected clients for a specific radio number of AP in a given time period. When there is no radio number entered in the radio_number field, the API filters the clients count for both radio 0 and radio 1. It is mandatory to provide the serial number of the AP to get the total count of clients for a specific radio number.

Support for Dual 5 GHz AP

Aruba Central (on-premises) supports automatic opmode selection for dual 5 GHz AP. When the opmode is set to automatic, AirMatch determines whether to convert a radio in an AP to 5 GHz operation instead of the 2.4 GHz and 5 GHz dual band operation. Automatic is the default dual 5G mode where Airmatch detects what is an optimal mode for the radios – dual band or dual 5G and updates the running opmode without requiring an AP reboot between the mode changes.

Manual setting of dual band and dual 5G is possible and the manual setting overrides the automatic mode and explicitly enables or disables the dual 5G mode. In this scenario, the AP immediately switches to the specified mode without a reboot and AirMatch maintains the specified channel and power assignments in the specified mode.

The following procedure describes how to configure automatic opmode selection for dual 5 GHz AP:

1. In the Network Operations app, select one of the following options:
   • To select an AP group in the filter:
     1. Set the filter to a group containing at least one AP.

        The dashboard context for the group is displayed.

     2. Under Manage, click Devices > Access Points.

        A list of APs is displayed in the List view.
        

   • To select an AP in the filter:
     1. Set the filter to Global or a group containing at least one AP.
     2. Under Manage, click Devices > Access Points.

        A list of APs is displayed in the List view.

     3. Click an AP listed under Device Name.

        The dashboard context for the AP is displayed.

     4. Under Manage, click Devices > Access Point.
2. Click the Config icon.

   The tabs to configure the APs are displayed.

3. Click the Access Points tab.

   The Access Points page is displayed.

4. To edit an AP, select an AP in the Access Points table, and then click the edit icon.
5. Click the Radio tab.
6. Set Dual 5G Mode to Automatic.
7. Optionally, specify the manual channel by setting Channel Assignment to Manual.
8. Optionally, specify the transmit power by setting Transmit Power Assignment to Manual.
9. Click Save Settings.
