The NetAlly LRAT-4000 LinkRunner AT 4000 Advanced Cable and Network Tester is for use with Multigigabit NBASE-T and fiber Ethernet networks. It includes comprehensive network discovery and topology mapping with advanced diagnostics and problem detection for in-depth troubleshooting. Using network discovery and layer 2 and 3 path analysis, the LinkRunner AT 4000 offers comprehensive network visibility to help resolve issues impacting multiple devices – not just a single link – while still providing the automated tests for moves/adds/changes validation and troubleshooting that the LinkRunner AT family of test solutions is known for.

Test results can be automatically uploaded to the Link-Live collaboration, reporting, and analysis platform to improve teamwork between network engineers and technicians, creating greater job visibility, better project control, and improved tester fleet management. Independent management plane via wired or Wi-Fi connection (with optional adapters) allows remote operation and result uploading separate from the network under test.

Discovery – Discover Network Devices and Common Problems Across Multiple VLANs, Plus Generate Topology Maps in Link-Live

The Discovery application creates an inventory of the devices on user networks along with their attributes: device types, names, addresses, interfaces, VLANs, resources, and other connected or associated devices. The app allows users to identify and analyze network devices and acts as a jumping-off point for further analysis using other apps, such as Ping/TCP, Path Analysis, and connection tests.

AutoTest and Profiles – Comprehensive Network Link Test Validates All Aspects of Network Connectivity

AutoTest is the most comprehensive testing application on the LinkRunner AT 4000. The app is fully customizable with savable test profiles and reusable Test Targets. Multiple profiles can be grouped allowing a single button press to validate connectivity on all VLANs. AutoTest results are automatically uploaded to the Link-Live platform after users claim their LinkRunner AT 4000.

Switch Test – Identifies Nearest Connected Switch and Critical Configuration Information

The Switch test provides a graphical representation of the immediate connection from the AutoTest results. The LinkRunner AT 4000 uses the IEEE Link Layer Discovery Protocol (LLDP), plus the Cisco and Extreme Discovery Protocols (CDP and EDP) to display the nearest switch name, chassis, model, slot, and port. Plus, displays other critical information like switch MAC/IP address, connected VLAN and VLANs supported, link speed and duplex (can identify advertised link speeds up to 10G), connection (MDI or MDI/X), and PoE voltage/power (actual and under TruePower load).

Path Analysis – Shows Switch/Router Path to Any Connected Device

Path Analysis traces the connection points, including intermediate routers and switches, between the tester and a destination URL or IP address. Users can use Path Analysis to identify issues such as overloaded interfaces, overloaded device resources, and interface errors. It also shows how devices within your network (and off-net devices) are connected to each other along a path including split routes.

Cable Test – Validate Cabling for Proper Termination, Test for Length, Common Miswires, and Distance to Fault

The Cable Test can help determine cable length and fault status, verify wire mapping of patch cords and structured cabling, and locate cables using toning or WireView office locators. Test structured cabling using the top RJ-45 port. Test patch cables with the built in second RJ-45 for complete pin to pin mapping and TDR.

Ping/TCP Test – Verify Connectivity to On or Off-Network Devices, Ensure TCP Port Availability

The Ping/TCP test app runs a Ping or TCP Connect test to the chosen target, allowing users to verify connectivity and identify intermittent issues. A Ping test sends an ICMP echo request to the selected target to determine whether it can be reached and how long it takes to respond. Test for MTU issues using the frame size and do not fragment settings. The results are trended, displaying the last 24 hours as well as loss statistics.

Capture – Packet Capture to 1Gbps for In-Depth Analysis

Packet capture is the process of recording network traffic in the form of packets as data streams back and forth over wired connections. Packet captures can help users analyze network problems, debug client/server communications, track applications and content, ensure that users are adhering to administration policies, and verify network security.

Reflector – Works with Other NetAlly Tools for Network Performance Testing

The LinkRunner AT 4000 offers a packet reflector mode, which enables you to conduct end-to-end network performance tests when used with other NetAlly tools (LinkRunner 10G, EtherScope nXG, CyberScope CE). This mode validates network throughput capabilities up to 1Gbps. The reflector also works for 1G LANBERT media qualification testing. The line rate reflector supports control of what types of packets to reflect as well as swapping of source and destination MAC and IP addresses for L3 performance testing.

Link-Live – Collaboration, Reporting, and Analysis Platform

Link-Live acts as a central system for managing test results and devices. It streamlines workflows by allowing easy logging, documenting, and reporting of test activities. When the tester is connected to Link-Live, test results are automatically uploaded to the dashboard for project management and reporting. In the case of no internet connectivity (air-gapped networks or new construction) results are buffered infinitely until connectivity is established.

iPerf – Runs iPerf3 Performance Test to NetAlly Test Accessory or iPerf Server Endpoint

iPerf is a standardized network performance tool used to measure UDP or TCP throughput and loss. It is used to verify ensure adequate client bandwidth is available.

Wi-Fi Connectivity Support – Requires Optional USB Adapter

The LinkRunner AT 4000 supports Wi-Fi connectivity through the use of an optional USB Wi-Fi adapter. This provides on-the-go connectivity for uploading test results to Link-Live, web remote control*, and for conducting basic Wi-Fi diagnostics using third-party apps. *Active AllyCare Premium Support required for web remote control.

Additional Tools and Diagnostics – App Store

Users can download apps from the Link-Live app store to accomplish many tasks in addition to testing. Using third-party apps and USB or BT/BLE accessories allows the user to use the system web browser to connect to infrastructure elements and other resources, take pictures of or scan asset tags for documentation and inventories, identify available Wi-Fi networks, print ID labels, manage trouble tickets, and much more.
