A simple, comprehensive network validation and configuration platform that empowers network professionals.

LinkRunner G2- Smart Network Tester

LinkRunner G2 Product Overview.

Discover Nearest Switch and VLAN

The LinkRunner G2 uses the IEEE Link Layer Discovery Protocol (LLDP), plus the Cisco and Extreme Discovery Protocols (CDP and EDP) to display the VLAN and nearest switch model, slot, and port.

The LinkRunner G2 displays critical nearest switch information include:

  • Switch name and model
  • Switch chassis, slot, and port
  • Switch IP Address
  • VLAN’s supported
  • Duplex and speed (actual and advertised)
  • Signal strength
  • Connection (MDI or MDI/X)
  • PoE voltage and power (actual and test limit)


TruePower PoE Loaded Test

LinkRunner G2 is the first field tester able to validate loaded PoE performance by drawing actual power up to 802.3bt 90W across all four pairs. Load the circuit to stress switches, cabling, and patch panels, all while measuring the voltage and pairs being used. Using the TruePower test to validate the power delivery before installing IoT connected devices ensures a smooth deployment and helps to alleviate finger-pointing.

Get Answers Fast with AutoTest

The LinkRunner G2 Li-ION battery can be charged via PoE and can power up in standby mode within a second. Enhanced, user-defined AutoTest can perform a required set of connectivity tests within seconds. The LinkRunner G2 Smart Network Tester enables you to quickly and accurately validate network health, and solve problems fast.

  • PoE loaded test up to 90W
  • Link speed and duplex (actual and advertised)
  • RX pair, polarity, and signal level
  • 802.1x authentication
  • Discover the nearest switch/slot/port and Data/Voice VLAN
  • DHCP discovery with vendor classification ID and Option 60 and 150 response, and show subnet and DHCP server addresses
  • Gateway and DNS server availability and responsiveness
  • Ping or TCP port connectivity tests to an unlimited number of user-defined targets

LinkRunner G2 AutoTest

Packet Reflector

The LinkRunner G2 packet reflector mode can be used as a remote device during end-to-end network path performance tests to validate LAN and WAN throughput capabilities up to 1Gbps.

LinkRunner G2 supports packet reflection for:

  • OptiView® XG Network Analysis Tablet
  • OneTouch™ AT Network Assistant

VLAN Monitor & Packet Capture

The LinkRunner G2 can monitor and show traffic distribution of the top 9 VLANs and capture 2GB of packets at line-rate.

Benefits of Android OS

Eliminate Security Risk of Using Personal Devices

Many technicians today use their personal mobile device on the job to access vendor apps, check trouble tickets, look up technical documents, calculate IP address ranges, configure network equipment, and more. However, the use of a personal device for job-related tasks could be considered a security risk. In addition, it may have only limited access to network infrastructure information (if connected to a guest VLAN, for example).

But the mobile device has no ability to validate wired Ethernet infrastructure – it cannot test PoE, cabling, link negotiation or network services. While it features Wi-Fi and Bluetooth connectivity, many networked end-point devices do not support these connection methods. So multiple tools are needed.


Workflow Efficiency Gains
Imagine how much time it would save to have a single device that could:

  • Receive a trouble ticket
  • View .pdf documents
  • Verify network services via AutoTest
  • Automatically document test results
  • Do all things Wi-Fi and Bluetooth that you can do with your personal mobile device with the optional Edimax 2 Wi-Fi/Bluetooth USB Adapter
  • On-board camera to document installed devices, scan QR/barcodes, etc.
  • Configure any IoT device that supports an Android app or web connection via Chrome browser
  • Use Android apps to do things like:
    1. Configure an IoT device (security camera, AP, lighting, HVAC)
    2. Telnet into a switch
    3. Run a speed test
    4. Access an IP calculator
    5. View info provided by a Bluetooth-supported sensor
    6. Plug in a USB printer and along with the companion Android app, print labels
    7. Get help – start a webex, invite others and share your screen enabling quick assistance without unnecessary downtime

Endless Possibilities

The possibilities are endless as the world of smart devices goes. Apps are available for virtually anything you need to do. Visit https://link-live.com/public/apps to see the current list of readily available free apps.

Automated Test Results Management to Link-Live Cloud Service

Serving as a centralized test results and device management system, the complimentary Link-Live cloud service transforms team workflows with the ability to quickly and easily log, document, and report test activity from all LinkSprinter, LinkRunner AT, LinkRunner G2, AirCheck G2, and OneTouch AT hand-held network testers. Once the instrument is connected to the Link-Live Cloud Service, your test results are automatically uploaded to the dashboard for project management and reporting. You have the option of uploading additional files, screenshots, images, profiles, packet captures, location information, and comments anytime. Also, certain NetAlly instruments with AllyCare Support can receive firmware updates “over the network” from Link-Live as they become available.

An API is available to retrieve and integrate data from Link-Live into other management platforms, such as your trouble-ticket application or network management system. This gives you the ability to easily provide proof-of-performance and better manage jobs and staff efficiency.​
