Wi-Fi Connectivity

The Wi-Fi Connectivity page displays an overall view of the connection details for all clients that are connected to or tried to connect to each connection phase. The connection phases include Association, Authentication, DHCP, and DNS.

To view the connectivity details page, complete the following steps:

  1. In the Aruba Central app, select one of the following options:
    • To select a group or site, set the filter to one of the options under group or site.
    • For all devices, set the filter to Global.

      The dashboard context for the selected filter is displayed.

  2. Under Manage > Overview, click Wi-Fi Connectivity.

To view the connectivity data for all the Instant APs in the Wi-Fi Wi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. Connectivity dashboard, ensure NTP Network Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. server is configured for all the devices and time is synced correctly corresponding to the respective time zone. If the time stamp is not correct, the telemetry data received from the Instant APs will be dropped. Also, set the firewall Firewall is a network security system used for preventing unauthorized access to or from a private network. to allow traffic on port 123 to sync the time with NTP server.

By default, the graphs on the Wi-Fi Connectivity page is plotted for a time range of 3 hours. To view the graphs for a different time range, click the Time Range Filter icon. You can choose to view graphs for a time period of 3 hours, 1 day, 1 week, or 1 month.

This section includes the following topics:

Connectivity Summary Bar

The connectivity summary bar displays the details of all clients in percentage. It displays the percentage success rate of each stage for the users to know the network performance.

Figure 1  Connectivity Summary Bar

The following table describes the information displayed in each section:

Table 1: Connectivity Summary Bar

Field

Description

All

Displays the aggregated success percentage of Association, Authentication, and DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  for all clients connected to the network.

Association

Displays the percentage of successful attempts made by a client to connect to the network.

Authentication

Displays the percentage of successful attempts of client authentication.

DHCP

Displays the percentage of successful attempts of DHCP requests and responses when onboarding a client.

DNS

Displays the percentage of successful attempts in the detected DNS Domain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. resolutions, when a client is connected to the network.

Connection Experience

The Connection Experience tile displays the overall success percentage, total number of attempts, number of successful attempts, total delays, and the total failures for each stage based on the selected time range filter. To view the connection experience for individual stage, select the stage type from the Connectivity Summary bar, the Connection Experience displays the chart for the selected stage. Select All to view the success percentage for all the stages. You can hover over the time series graph to view the success percentage for a specific time. The individual stage displays the Attempts, Failures, Success, and Delays on the time series graph.

Figure 2  Connection Experience Tile—Global or Group Context

Only in the site context, the Connection Experience tile provides the Baseline Comparison option. You can compare the connection with either Company Baseline or Class Baseline.

The following comparisons are available:

  • Company Baseline—Compares the connection between the selected site and other sites associated to the same user. It is selected by default.
  • Class Baseline—Compares the selected site and sites having similar configuration. The baseline is denoted by orange dotted line on the time series graph and blue line is the Wi-Fi connection of the selected site.

AI Insights

The AI Insights tile provides a list of AI Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. AI reduces trouble tickets by identifying the network entity that is facing problems through event correlation and root cause analysis. Insights generated for a selected time range. To view the details, click on a selected AI Insight. The page gets redirected to the AI Insights under the AI Insights page. Click each of the listed AI Insight for a detailed analysis based on the impact on the network. For more information on AI Insights, see The AI Insights Dashboard.

AI Insights is not implemented at a Group level and the page displays No AI Insights observed.

The following animation shows how to view the AI Insights in the selected stage.

Connection Problems

The Connection Problems tile displays the details of Failures and Delays graphically for each of the categories from the drop-down list. Each graph displays the top five MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. addresses or SSID Service Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. based on the selected category. Each category in the Connection Problems drop-down lists changes based on the selected stage in the Connectivity Summary bar. Selecting the required category from the drop-down displays the failures and delays in a pie chart with percentage, and a bar graph with the number of failures and delays. Hover the cursor over each graph to view the number of failures or delays for each stage.
