Access Point > Overview > RF

In the access point (AP) dashboard, the RF tab provides details corresponding to 2.4 GHzGigahertz., 5 GHz, and 5 GHz Secondary radios of the AP.

Viewing the Overview > RF Tab

To navigate to the RF tab in the AP dashboard, complete the following steps:

  1. In the Network Operations app, set the filter to one of the options under groups, labels, or sites. For all devices, set the filter to Global. Ensure that the filter selected contains at least one active AP.

    The dashboard context for the selected filter is displayed.

  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. In the AP dashboard context, click the RF tab.

    The RF tab is displayed.

To exit the AP dashboard, click the back arrow on the filter.

You can change the time range for the RF tab by clicking the time range filter and selecting one of the available options: 3 hours, 1 day, 1 week, 1 month, and 3 months.

You can hover over the graph to view more information. You can select or clear an option in each graph to filter the data displayed on the graph. For example, if you uncheck the box corresponding to Receiving and Non-Wifi interference in the Channel Utilization graph, only Transmitting data is displayed on the graph.

The RF tab provides the following details corresponding to 2.4 GHz and 5 GHz radio channels of the AP:

Channel Utilization

The Channel Utilization graph indicates the percentage of channel utilization for the selected time range from the time range filter. The channel utilization information is categorized as follows:

The following figure displays the channel utilization graph for 2.4 GHz radio channel:

Noise Floor

The Noise Floor graph indicates the noise floor detected in the network to which the device belongs.

Frames - 802.11

The Frames - 802.11 line graph indicates the trend of frames transmitted through the network. The frames can be one of the following types: Drops, Errors, and Retries. The graph indicates the status of data frames that were dropped, encountered errors, retried to be transferred, in a wireless network. You can see the graph in percentage or frames/sec.

Only Campus APsCampus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. and Remote APsRemote APs extend corporate network to the users working from home or at temporary work sites. Remote APs are deplyed at branch office sites and are connected to the central network on a WAN link. support the Issues & Transmitted Frames and Issue % filter options.

Select one of the following option from the drop-down:

  • Issues & Transmitted Frames—Select to view the trend value for transmitted frames along with retries, errors, and drops in frames per second
  • Issue %—Select to view the trend value for retries, errors, and drops in percentage.

Radio Errors

The Radio Errors graph indicates the Total Packets, Physical Errors, and MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. Errors in packets per second.

Only Campus APs and Remote APs support the Physical Errors, and MAC Errors options.

Channel Quality

The Channel Quality graph indicates the quality of channel in percentage.

When you hover over the Channel Utilization, Noise Floor, Frames - 802.11, and Channel Quality graphs, it displays specific data for the selected timestamp.

The tri-radio feature is available only for AP-555. In the RF tab, the Radio 5 GHz (Secondary) tab is available only if the tri-radio mode is enabled. For more information, see About Tri-Radio Mode.

The Actions drop-down list contains the following options:

Go Live

Aruba Central (on-premises) supports live monitoring of IAPs that support Aruba Instant 8.4.0.0 firmware version and above. Aruba Central (on-premises) allows you to monitor live data of an AP updated at every 5 seconds. For more information, see Enabling Live IAP Monitoring.
