User Experience Insight Deploy

This section details the steps to deploy UXI for Orange Widget Logistics (OWL) described on the Reference Customer page. The IT department has a centralized helpdesk call center in the Roseville, CA, headquarters, with no IT presence in other branch and office locations. UXI will be deployed and configured to monitor network and application performance at the Seattle campus. The deployment process in this guide can be repeated for the rest of the locations. The deployed solution uses the following products:

• Aruba UXI Cloud Dashboard
• Aruba UXI Sensor UX-G5 and UX-G6 Series

Prepare for UXI Deployment

Completing the preparatory tasks below is crucial before installing and configuring the UXI sensors. This ensures a smooth and successful deployment of the UXI sensors for network and application performance monitoring.

URL Access

UXI sensors communicate with multiple systems to download configuration and upload test results. The URLs below must be accessible for the sensors to function correctly. Additional services used for testing should also be allow-listed to enable proper testing.

Backend Systems

The URL https://device-gateway.capenetworks.io is essential for all communication between Aruba UXI sensors and their backend systems. The sensors must be able to access it.

Caution: Do not use SSL decryption for the URL above.

Date and Time

The sensor uses one of the following methods to obtain the correct time:

• NTP servers provided in DHCP option 42.
• The publicly accessible 0.pool.ntp.org NTP server(s).

• If NTP is unavailable, the sensor syncs time via HTTP from http://device-gateway.capenetworks.io/ on port 80.

• If the URL http://device-gateway.capenetworks.io/ is not accessible on port 80, the sensor attempts to sync via HTTPS from https://device-gateway.capenetworks.io/ on port 443.

Captive Portal and Proxy Detection

Reachability to http://cdn.capenetworks.io/auth on port 80 is a critical test for detecting the presence of a captive portal and identifying potential proxy-related issues during the UXI sensor’s test cycle. Depending on the test results, the sensor takes appropriate actions, such as continuing the regular test cycle, running the captive portal test, or reporting errors related to the captive portal and proxy configurations. More details can be found in the UXI Troubleshooting Guide.

External Connectivity Detection

The sensor uses the following URLs to test for external connectivity. If the URLs cannot be accessed, the sensor reports a No connectivity issue on the dashboard.

http://cdn.capenetworks.io/auth

http://cdn.capenetworks.io/connectivity-check

http://35.241.22.134/auth.html

http://35.241.22.134/connectivity-check

http://captive.apple.com/hotspot-detect.html

http://connectivitycheck.gstatic.com/generate_204

Caution: If a network has a captive portal in place, it is advisable not to allow-list the above URLs, which may prevent the proper redirection of the sensor to the Captive Portal. Instead, these URLs should be accessible, but unauthenticated clients should receive a captive portal redirect response.

More information can be found in this UXI URL help article.

Activate UXI Account on GreenLake Cloud Platform (GLP)

The HPE Greenlake Cloud Platform (GLP) provides a common interface to access and manage all HPE cloud applications in one place. HPE Aruba Networking User Experience Insight (UXI) is taking steps to be an application on GLP.

Step 3 Verify that the sensor moves to the Configured list.

Step 4 Repeat steps 1 and 2 for the remaining sensors.

Mount and Connect

Because Aruba UXI sensors are intended to test user experience, they should be placed where users connect. They can be permanently fixed in certain areas or temporarily relocated for events that may require extra monitoring, such as company meetings or press conferences.

OWL’s requirements call for the permanent installation of three UXI Sensors.

Detailed installation steps and options can be found in the Aruba User Experience Insight (UXI) - Sensors tech brief.

Monitor

The time a sensor takes to be detected on the dashboard can vary depending on what process it needs to go through.

When the sensor is first powered, startup software is activated to facilitate faster onboarding: this is designated by a solid white LED. The software uploads an AP scan while the main software is still starting up. On Ethernet, the sensor should be detected on the dashboard within 30 seconds or about 40 seconds when using mobile only.

If the software onboarding does not succeed, wait for the main software to run (designated by the flashing white LED) before the sensor is detected. This will happen about 2 minutes after powering up the sensor.

The time for the sensor to start testing an SSID varies from this point onward. If the sensor must update to the latest release, testing starts approximately 5 minutes after powering up (if configured on the dashboard). On a bad mobile connection or if the software requires multiple updates, the time can be extended to 10-15 minutes.

Note: If the LED color is orange, the sensor has no external connectivity.

See the legend below for the meaning of the sensor LED status lights:

STATUS LIGHT

When all three sensors are connected and mounted, log into the UXI dashboard to verify they are collecting performance data as designed.

This concludes the UXI deployment for example customer, OWL Corporation.
