Home screen

The LinkRunner G2 Smart Network Tester is a rugged, fast, and complete copper and fiber Ethernet network connectivity tester. The LinkRunner G2 Smart Network Auto-Tester performs the essential set of network connectivity tests, enabling you to quickly and

The LinkRunner G2


Allows you to quickly validate switch connectivity and configuration.
Benefits: Quickly view switch information, such as name/port, detected link speed/duplex, and VLAN configuration. If PoE is enabled, test the power that the switch can offer under load, against what the switch advertises.

The LinkRunner G2

Flash Port

Causes the switch port on which the LinkRunner G2 is connected to flash rapidly.
Benefits: Quickly and easily identify on which switch port the LinkRunner G2 is connected.

The LinkRunner G2


Runs a suite of functional tests, from cable to network service availability.
Benefits: Reduces time and effort by replacing the need to use multiple tools and follow multiple procedures to functionally verify the network’s ability to support clients or IoT devices.

The LinkRunner G2

Add Pictures or Comments

Attach pictures or comments to your test results.
Benefits: Simplify the process of documenting what you see by attaching photos, screenshots, or comments to your test results. Everything with a single device!

The LinkRunner G2


Validate cable wiring and distance, or identify cable faults.
Benefits: Quickly identify cable faults like opens, shorts, or split pairs. You can also validate the wiremap, cable length, or see if the other end of the cable is connected to a switch/station.

The LinkRunner G2


Apply a tone to the cable. Benefits: Simplify the process of tracing a cable by applying different types of tones. No need to disconnect the cable from the switch!

The LinkRunner G2


Provides access to saved profiles, settings, and other tools.
Benefits: Quickly adjust to your test environment by changing profiles on the fly, or modifying settings as required. Easily gain access to useful tools that allow for VLAN monitoring or packet captures.

The LinkRunner G2


Provides multiple configuration options, such as date/time, language, test targets, PoE, IP Address and VLAN, etc.
Benefits: Quickly adjust to your test environment by easily creating configuration profiles that can be used when needed.

The LinkRunner G2

VLAN Monitor

Monitor VLAN traffic on a trunk port.
Benefits: Quickly validate that all supported VLAN’s are available. Easily determine the root cause of VLAN over-subscription by visualizing which VLAN’s are handling the highest amount of traffic.

The LinkRunner G2


Allows you to perform a packet capture.
Benefits: Simplify the process of troubleshooting the most complicated performance problems by performing a packet capture. No need to install sniffers or carry around laptops.

The LinkRunner G2


Allows you to download and install new apps.
Benefits: Get things done faster by having all the tools and apps you need to troubleshoot, validate, and manage the network on a single device. Anything from speed test apps, Barcode Scanners apps, switch configuration apps and lots more!


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 including:
– 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 for up to

LinkRunner G2 is the first field tester able to validate loaded PoE performance by drawing actual power up to 802.3bt 90-100W across all four pairs. It is able to load the circuit to stress switches, cabling and patch panels, all while measuring the voltage and pairs being used. Using the TruePowerTM test to validate the power delivery before installing IoT connected devices ensures a smooth deployment and helps to alleviate finger-pointing.

Get Answer Fast with Autotest

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

– PoE loaded test up to 90W
– Link speed and duplex (actual and advertised)
– RX pair, polarity and signal level
– 802.1x authentication

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

The LinkRunner G2 can monitor and show traffic distribution of the top 9 VLAN in Pie-chart, and capture 2GB of packets at link-rate.

Automated Test Results Documentation to Link-live Cloud Service

Link–Live allows test results from LinkSprinter, LinkRunner AT, LinkRunner G2, AirCheck G2, and OneTouch AT hand-held network testers to be automatically uploaded to the cloud, providing users with a unified dashboard of both wired and Wi-Fi network connectivity results.

Test results are automatically sent to your secure Link-Live results management dashboard providing organizations with a newfound ability to quickly and easily document the network. This provides organizations with the ability to provide proof-of-performance and better manage jobs and staff efficiency.

Link-Live provides a centralized location for managing testers software, serial number and users, and organize test results from testers regardless of network type, Wi-Fi or wired:

– Reduces results management overhead for multiple testers and users
– Broadens and quicken collaboration perspective and capability
– Simplifies report across media types for network deployment
