Datasheet: OneTouch™ AT G2 Network Assistant

Reduce access network deployment project risk and troubleshooting time

More than 70% of IT organizations lack standardized processes to validate deployment and solve problems. This results in more than 1 hour (average) to resolve problems. In addition, 40% of IT tickets are not solved the first time and require escalation. Intermittent problems can take twice as long to resolve.

By automating and standardizing the validation & troubleshooting process, the OneTouch AT Network Assistant empowers novice network technicians to validate performance easily, solve more problems faster, and escalate issues more efficiently – allowing more IT projects to be completed on time and with quality, freeing up engineer’s time.

OneTouch AT features

Versatile copper, fiber and Wi-Fi troubleshooting

Be ready for a broad range of troubleshooting scenarios with the handheld OneTouch AT G2 Network Assistant. The tester incorporates dual copper and fiber optic test ports to facilitate troubleshooting of 10/100/1000 Mbps twisted pair and 100/1000 Mbps fiber Ethernet networks. The dual ports simplify inline packet capture and VoIP monitoring by eliminating the need for mirror ports or taps. For troubleshooting Wi-Fi networks the OneTouch AT G2 tester incorporates an 802.11ac dual-band Wi-Fi radio with a 3x3 antenna. When connected to both wired and Wi-Fi networks the tester displays test results side-by-side on a single page to aid in problem domain isolation.

The OneTouch AT Network Assistant has a modular design. A 10G module is available for testing wired 100Mbps to 10Gbps Ethernet switch port and link performance at up to 10Gbps rate.

All-in-one testing from the patch cable & Wi-Fi to the cloud

When validating and troubleshooting the access network, one needs to test from where the client device is connected to the network—where the device could be a PC, tablet, smart phone, IP phone, printer, POS terminal, industrial equipment controller, a medical imager etc. The OneTouch AT can prove that the network is good —by emulating the client device and measuring network performance. It measures, analyzes and documents the performance of each the critical network elements: the network cabling, the delivery of Power over Ethernet (PoE), the connection to the nearest switch, the connection to the nearest access point, and the performance of key network services and server-based applications in the intranet, and cloud or internet.

Standardized network validation and troubleshooting

Use the intuitive touch interface and the Setup Wizard to create test profiles, where a profile is a set of tests, tailored to specific networks, services, and applications. Build profiles to accommodate different types of users, devices, locations or technologies. Profiles can be very simple with just a few tests or advanced with dozens of tests. Once created, profiles can be saved for quick and easy reuse. Create a library of standardized profiles to elevate the troubleshooting know-how of the entire network support staff. Share profiles with other OneTouch AT users. Use the profiles to establish best practices for consistent, faster, more productive troubleshooting and network acceptance testing.

Automated suits of test with pass/fail analysis

Test everything defined in a profile automatically with the one button AutoTest. The AutoTest progresses from the physical layer of the network through the wired and wireless infrastructure, to network services and user-defined applications. Clear pass/fail and warning indicators highlight potential problems. A top-level pass/fail indicator provides the overall AutoTest status at a glance.

Centralize Cloud-based management

Organizations can claim their OneTouch AT units to the cloud portal. Claimed units will be visible from the cloud portal as long as they are connected to the internet. They can be remotely managed when and where convenient using a smart device through its web browser. Users can upload test results, download latest software and test profiles, and remote control their OneTouch AT. Users can view and analyze test result on the cloud portal.

Centralize report management supports storing and viewing of test results from other NETSCOUT handheld network test products, such as LinkSprinter, LinkRunner AT, and AirCheck G2. After each test, test results and reports from these test units can be exported and stored to A user can setup such that an email will be sent to the operator of the OneTouch so that he can enter comments, such as test location, and/or upload picture(s) of the test environment. Multiple parties can access the Link-live Cloud Portal over the web at anytime from anywhere using a smart device or PC via a web browser. Free-string match search, and filter condition make it easy to locate the test report(s) of interest by text in comment or the test result.

Figure 2. Link-live consolidate test results from OneTouch AT and other NETSCOUT Handheld Network Test products.


Remote visibility, control and file access

Use the built-in RJ-45 management port or optional USB Wi-Fi adapter to remotely control the OneTouch AT and access saved files. Any action that can be performed directly on the OneTouch AT using the touch screen can be performed remotely using a PC, laptop, tablet or smart phone. Minimize the time, expense and inconvenience of traveling to the client location where the problem was reported. Webcam support enables live, remote viewing of the physical environment near the tester.  Remote control of units via the Cloud Service also allows traversal of NAT devices, which is very advantageous when troubleshooting from outside the office.

Test Features

Copper and fiber optic cable testing

Troubleshoot cable performance quickly by measuring twisted pair cable wiremap and length. Use cable identifiers and tone probe to locate and identify cables. Measure the optical power received through fiber optic links. Verify the cleanliness of fiber optic connections by viewing connector end faces with the optional USB video probe.

PoE testing (Supported with OneTouch AT G2 Module)

Verify the successful delivery of PoE with the TruePower™ load test. Emulate an 802.3at (PoE+) class 1-4 powered device and measure power up to 25.5 watts. See the requested and received PoE class, the pairs used, the PSE type, measured PoE voltage unloaded and under load, and PoE power under load.

Wi-Fi and wired client devices connectivity testing

Understand how a client device connects to the wired infrastructure by testing link negotiation, identifying the nearest switch, and monitoring key switch port statistics. The OneTouch AT with G2 Module tests IEEE 802.11a, .11b, .11g, .11n and .11ac Wi-Fi networks. It shows understand how a client device connects to the Wi-Fi infrastructure by testing the link between the client and the nearest access point, identifying the AP name, channel and security type, observing the authentication and association process, and monitoring key AP and network statistics, including roaming details by AP. For Wired client, the OneTouch AT with G2 Module tests 10/100/1000BASE-T twisted pair and 100BASE-FX/1000BASE-X fiber optic Ethernet networks, while the OneTouch AT with 10G Module test RJ-45 test port for 100/1000/10GBASE-T and 1000 BASE-X SFP/10 G BASE-SR/LR SFP+ Ethernet over optical fiber Network.

Network services testing

Test DHCP server responsiveness. Identify the wired and Wi-Fi DHCP servers and view the offer and acceptance timing and the lease information. Test DNS server responsiveness. Identify the wired and Wi-Fi DNS servers and view the DNS lookup time. Also, determine if a second DHCP address is being offered. If unexpected or is a potential rogue server, use the path analysis tool - a layer 2 and layer 3 trace route - to track down the device to mitigate a problem situation.

Figure 6. Detailed breakdown of DHCP provisioning and response performance

Figure 7. Path Analysis showing the path through switches from OneTouch to a client.

Network application testing

Determine if a server-based application is the root cause of a reported problem by measuring availability and response metrics. Add to the AutoTest profile the performance test appropriate for the application: ping (ICMP), connect (TCP), web (HTTP), file (FTP), multicast (IGMP), video (RTSP) or email (SMTP). Each test is graphically represented on the OneTouch AT home page as an icon. After running the AutoTest, touch a test icon on the home page to get a detailed breakdown of application performance including DNS lookup time, server response time and data rate. The test results are presented side-by-side for easy wired/Wi-Fi and IPv4/IPv6 performance comparisons. A few examples: ping your WLAN controller, connect to port 2000 on your VoIP call manager, download a page of an application with a web interface, upload or download a file from a server, subscribe to a multicast group, access video content from an on-demand streaming video server or email a text message to your mobile phone.

Figure 8. Detailed breakdown of network-hosted application performance

Figure 9. Group tests by hosting location – local, intranet, internet

Local, intranet and internet performance

Understand the performance of network services and server-based applications wherever they are hosted: locally in the datacenter, on a corporate intranet server or on a server reached via the public internet. Create location centric AutoTest profiles by grouping together co-located services and applications. Measure service levels to the different groups to quickly spot problems.

    Enterprise network managers use the Wired Performance tests for:
  • Assessing network performance prior to deployment of new services or network infrastructure
  • Validating the performance of newly installed network infrastructure and critical network links within the LAN or data center
  • Troubleshooting network and service performance problems
  • Verifying independently that service providers are meeting agreed upon service levels (SLAs) and maintaining QoS end-to-end
    Service providers and system integrators use the Wired Performance tests for:
  • Documenting network performance from layer 1 to 7 where the documentation serves as proof that the services they provided were delivered successfully
  • Providing value-added service to their enterprise customers in the form of network assessments and troubleshooting

1G and Wi-Fi End-to-end path performance measurement

Ensure that newly installed or upgraded wired and Wi-Fi networks meet SLA objectives and are ready for new high-bandwidth applications by measuring end-to-end path performance. Measure throughput, frame loss, latency and jitter between a local OneTouch AT G2 connected to Wi-Fi or wired client network, and a remote OneTouch AT peer or a remote LinkRunner reflector connected to the end of path to test. A remote peer provides upstream and downstream results while a remote reflector yields round trip results. Measure performance at rates up to 1 Gbps on copper and fiber networks and 600 Mbps on Wi-Fi networks. A special use model exists that enables testing from the OneTouch AT wired interface to the Wi-Fi interface on the same instrument for testing without a remote.

Wired network discovery and analysis

Automatically discover copper and fiber-connected devices and key device properties. Select from among fourteen different sorts to obtain different views into the wired network. For example, sort by IPv4 or IPv6 address to identify used and available addresses. Or sort by switch name/slot/port to understand where on the network devices are connected. Sort by discovered problems to quickly identify potential issues. Additional discovery-assisted analysis tools aid with troubleshooting and profile creation. For example, the Multiport Statistics tool provides visibility into switch, router and AP port statistics including speed, duplex, slot, port, VLANs, host count, utilization, discards and errors. The Devices on Port tool provides visibility into the devices connected to an individual switch port. The Path Analysis tool provides a layer 2 and 3 trace route from the OneTouch AT to a target device including time to each hop and SNMP switch and router port statistics.

Wi-Fi discovery and analysis (supported by OneTouch AT with G2 Module)

Automatically discover Wi-Fi devices and key device properties. Select from among twenty context-relative sorts to obtain different views into the wireless network. For example, sort by signal strength to troubleshoot Wi-Fi coverage issues. Sort by MAC manufacturer to discover Wi-Fi devices by type and to understand how they are connected relative to SSID, AP and channel. Sort by channel to identify channel spacing and usage problems. Sort by authorization status to find potential security violations. Additional discovery-assisted analysis tools aid with troubleshooting and security enforcement. If a Wi-Fi device is also discovered via Wired Analysis, the Cross Link feature enables one-button toggling between wired and Wi-Fi analysis views.

Inline VoIP analysis (Supported by OneTouch AT G2 Module only)

Connect the OneTouch AT inline between an IP phone and the network for real-time troubleshooting and analysis. The VoIP analysis test reveals issues related to PoE, DHCP, TFTP, SIP, and SCCP. The test provides visibility into unencrypted SIP and SCCP traffic to debug VoIP phone problems and quantify the quality of a VoIP call. Simultaneous capture of the VoIP conversation is optional.

Figure 17. Inline VoIP analysis simplifies troubleshooting of desktop VoIP problems in real-time without TAPs or switch mirror ports

Figure 18. VoIP Analysis shows the entire call setup process as well as quality of the VoIP call in each direction

Packet capture

Capture wired and AutoTest traffic when a packet-level view is required to solve a complex network or application issue. Filter the traffic to capture what is most important. Export the capture file to a PC for decoding and analysis using protocol analysis software. Capture wired traffic on a single port, on two ports aggregated, or inline between a client device and the network. Inline capture avoids the complexity, time and cost associated with standalone taps or configuring switch mirror ports. The OneTouch AT with G2 Module can capture VoIP traffic, and Wi-Fi traffic by channel and mode (20 MHz or 40 MHz+).

Figure 19. Inline packet capture simplifies documentation of client application problems without TAPs or SPAN ports

Figure 20. Capture packets to solve complex issues

Streamline collaboration

Collaborate with peers, consultants, integrators and vendors more effectively by sharing packet captures, screen shots and AutoTest reports. Remotely control and view the user interface and remotely access files using a PC, tablet or smart phone. Attach a web cam to the OneTouch AT to share a view of the test environment.

Save test results

Save the test results to share with colleagues or outside parties. A report serves as trouble ticket documentation, as a record of historical performance for benchmarking or as a certification report after new infrastructure deployment and turn up. Define which test results to include in the report (AutoTest, Wired Analysis, Wi-Fi Analysis, Tools Settings, and VoIP Analysis) and the report format (PDF, XML). Open the results in a spreadsheet for flexibility in results analysis.

Setup wizard

Simplify AutoTest profile creation while learning about the tester's capabilities by running the Setup Wizard. The wizard simplifies profile creation with step-by-step guided instructions, yes/no prompts, on-screen help and graphical progress indicators. Experienced users can bypass the wizard if desired.
