OneTouch AT Overview

Common Use Cases

  • Standardizing, Validation & Troubleshooting

    Standardizing, Validation & Troubleshooting

    1. A skilled technician is hard to find. It is difficult to train an unskilled technician to know what to test, and what to look for during move, add, and change projects, and troubleshooting as access network configuration changes with client location.

      OneTouch AT’s AutoTest feature tests connectivity and performance of the access network and allows standardization of the validation procedure, empowering the field team to be more productive after deployment and during troubleshooting.

    2. Home screen with suite of tests from basic services to intranet or internet/public cloud.

    3. Multiple profiles can be defined that contains different sets of test based on site/location/subnet that the OneTouch will be located.

    4. New profile loaded with complete set of pre-defined tests and thresholds. One click of the TEST button executes the entire suite of tests.

    5. Test will start with basic service, such as cable, switch port and/or Wi-Fi AP connectivity and then proceed to validate functionality of basic services such as DHCP/DNS and Gateway.

    6. Then, OneTouch will perform a throughput test to one or more end-points on the Intranet and even to external networks as long as a performance peer is present.

    7. Then various user defined tests to application servers, such as web, email, FTP, in the intranet &/or extranet will be performed. Pass, Fail or warning result for each test is show on home screen.

    8. Users can click on a test icon to review test setups and results. Tools, such as path analysis, packet capture, are available to help troubleshoot further to determine the root cause.

    9. Users can then save the test result in PDF and/or XML format.

    10. Test report will includes summary and detail test result of each test in the AutoTest, and optionally inventory of Wired and Wi-Fi devices discovered.

  • Intermittent Network Performance

    Intermittent Network Performance

    1. Some users at a site complain that “the Wi-Fi Network is slow” at one part of the office. One of the problems can be co-channel interference created by having too many access points on a channel.

      OneTouch AT makes this task easy with full analysis of the Wi-Fi RF health to detect, locate and resolve the problem.

    2. AutoTest profile can be configured to connect to the Wi-Fi network with SSID = Demo_SSID. Demo_AP is the AP used and it shows everything is OK.

    3. Click on AP ICON to show the KPIs of the AP: signal strength noise, channel, 802.11 type.

      The OneTouch is connected to a 160MHz bonded with center channel at 112. However, other users that experience problem were connected at 2.4GHz.

    4. Scroll down to see Transmit rate, Retry rate, utilization and # of AP using the same channel also showing everything is OK with only 1 AP on this 160MHz channel.

    5. Exit back to home screen & select Wi-Fi analysis to look at the health of the RF environment.

    6. Wi-Fi Analysis shows all SSIDs present. For Demo_SSID, the ICONs on the right shows that there is are 6 AP on this SSID and the SSID spans 8 WiFi channels.

    7. Select the channel ICON to show the Wi-Fi channels that the SSID is on. The current 802.11 and non-802.11 utilization on the channel is shown.

    8. Click Show All allows user to review the overall utilization of all channels, in both 2.4 and 5GHz band. Notice channel 11 has 4 AP’s, and all 2.4GHz channels are affected by Interferer. The dark blue portion of the bar shows the bandwidth consumed by non-802.11 signal.

    9. Clicking on channel 11 will drill down to view the % bandwidth utilized. Noticed the number of AP, # of clients on channel 11 is shown on the buttons on the right.

      It does seems that poor performance of the network is caused by interference. But let’s double-check to make sure that there is no rogue AP on channel 11 under the Demo_SSID

    10. Select the AP ICON to see the AP’s that are on the channel 11. The ICON on the left shows the user defined status of the AP. Clicking on the button to drill down for more detail about the AP.

    11. By invoking Tools, you can connect, locate or capture traffic to/from the selected AP, for further investigation. After verifying, un-authorized AP’s, we can classify them as Authorized for quick distinction in the future.

  • Locating Wi-Fi Interferers

    Locating Wi-Fi Interferers

    1. Some users at a site complain that “the Wi-Fi Network sometime is slow”. Devices that transmit non-802.11 signal at the same frequency as Wi-Fi devices can hog bandwidth and caused retransmission. OneTouch has a special antenna that can detect, identify and locate these devices.

    2. OneTouch starts with a AutoTest. Click on Wi-Fi Analysis to investigate Performance problems.

    3. Click on Demo_SSID Network to see AP/Network Details.

    4. It shows that the AP’s signal strength is good, but there is an interferer present.

    5. All the interferers affecting the Demo_SSID, since the start of the Wi-Fi Analysis, are displayed. Devices currently affecting are shown ACTIVE. We note that the Wireless Camera has high utilization.

    6. Drilling into the camera shows that it has high power and persistently consumed 24% utilization. We can use the tools button to use the locate feature to find its location.

    7. The OneTouch AT comes with a unidirectional antenna that works with the locate function to track down the interferer source.

  • Slow Internet Application

    Slow Internet Application

    1. Users complain that their Web Application is slow. Oversubscribed devices using internet between client and the application server can hurt user experience. OneTouch AT offers analysis features to identify the path and isolate the location of the congestion.

    2. OneTouch can test against many types of application servers: Web, Email, FTP, IGMP and RTSP.

    3. Click on the Web download results tab and it shows data transfer times on wired was problematic with the “X” and Total Time is 1 second.

    4. Using OneTouch, one could drill down to Path Analysis from OneTouch to the server, open a browser or a Telnet session to log-on to a device such as Router/Switch.

    5. The path analysis shows that there is a warning on the DemoRouter.

    6. Clicking on the DemoRouter shows that the port connecting to the H3C switch was overloaded. Looks like it is time to increase bandwidth of this upload between H3C and DemoRouter.

  • Client Cannot Connect to Internet

    Client Cannot Connect to Internet

    1. Some users in a remote office complain that they are unable to connect to the internet. Rogue home router/AP that dub as DHCP server can hijack users and cause problem. Let’s see how OneTouch AT detects and locates the rouge device.

    2. During AutoTest, we note that there was a warning icon on the DHCP service test.

    3. IP subnet offered by DHCP Server from Wired network was incorrect subnet.

    4. Use the Tool button to select Path Analysis - Wired to the 1st DHCP server.

    5. Path Analysis shows the switch port that the DHCP server is connected.

    6. Clicking on the device shows the port the device is connected and traffic loading on the port. Technicians can then disconnect the rouge DHCP server quickly.

  • Remote Site Path Performance Testing

    Remote Site Path Performance Testing

    1. Having the ability to test the Wi-Fi and wired network together for a full path analysis is challenging to do. Since somewhere the wireless network connects to the wired network, performance testing of both networks is often overlooked. OneTouch is the only tool in the industry that can simultaneously test the wireless and wired network together so you can see the end-to-end performance.

    2. A profile can contain multiple end-to-end Network Performance Tests including unique test from the OneTouch Wired interface to its Wireless Interface.

    3. Each test can be programmed with different max throughput, lost limit, frame size, and test duration. DSCP and protocol port# can be set.

    4. Each test can be programmed with different max throughput, lost limit, frame size, and test duration. DSCP and protocol port# can be set for test up to full 10Gbps rate.

    5. Multiple performance tests with different Peer IPs and test parameters can be defined in an AutoTest to verify performance of different network link paths.

    6. For testing against a peer, such as another OneTouch, the IP address of the Peer will be needed along with the max throughput, loss limit, frame size to use can be defined. Individual test can be invoked by pressing the TEST AGAIN button.

    7. Test result shows the maximum throughput, jitter and latency at zero packet lost.

    8. The result for throughput, packet loss and latency can be charted against frame sizes tested.
