Importance of Automated Network Connectivity Testing

Paramount to the deployment of any type of network-connected device is validating link and network services from the point where end devices connect to the network. By automating those many tests in a simple but complete AutoTest, instead of requiring specialized expertise to understand the many underlying elements of network connectivity, even the least experienced technician can execute the test.

AutoTest performs a default set of key network connectivity tests in seconds, providing a standardized test process that enables technicians to quickly and accurately identify if the problem is in the connected device, the network, or lack of proper PoE being supplied to the RJ-45 jack.

Standard AutoTest includes:

  • TruePower™ PoE Class 0-4, UPOE
  • Link speed/duplex
  • Nearest switch including slot/port/VLAN/Voice VLAN
  • DHCP IP Address assignment
  • DNS Validation
  • Gateway Router Validation
  • Reachability to target resource (I.E. Internet)

When customization of the AutoTest is needed, profiles can be defined to ensure a standardized test process is executed when variables about the link under test are needed. While these settings can be easily changed in use, profiles can be configured by a senior team member to ensure less-skilled technicians are executing an AutoTest that is specific to their network environment, which is particularly useful in organizations who manage distributed locations.

Examples include:

  • Site-specific PoE configuration
  • 1000BASE-T validation
  • 802.1x authentication
  • IPv4/IPv6
  • DHCP/Static IP
  • Proxy settings
  • VLAN ID and Priority
  • User-defined MAC
  • Up to 10 custom-defined ping or TCP port open targets

At the completion of each AutoTest, the result is automatically uploaded into the included Link-Live results management and reporting database and sent to any number of recipients via email. Users have the ability to add additional information that will append to the link test either directly from LinkRunner G2 or through email.

Examples of useful information to document with the AutoTest result:

  • Trouble ticket number
  • Jack location
  • Use the on-board camera along with an Android app to scan a QR/Barcode
  • Attach a photo of a serial number, asset tag or just proof of device install


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

  • EU-WIFI-BT-USB: Edimax n150 Wi-Fi & Bluetooth USB Adapter for Europe. Channels 1-13

*Fiber SFP not included, sold separately.

Nearest switch and VLAN information over Copper and Fiber Links - uses IEEE Link Layer Discovery Protocol (LLDP) plus the Cisco ® and Extreme Discovery Protocols (CDP and EDP) to display the VLAN/Voice VLAN and nearest switch model, slot and port. When reported as part of the AutoTest, a Refresh option is available that allows you to receive the next xDP frame (CDP/LLDP) coming from the switch.

TruePower™ PoE testing - quickly validate PoE performance by drawing actual power utilizing all 4 pairs such as UPOE. Load the circuit to stress switches, cabling and patch panels, all while measuring the voltage and pairs being used.

Link Speed/Duplex - verify link speed and duplex is configured as expected. If 1000BASE-T test is enabled and the link under test is not performing as expected, a yellow warning indication will be noted and the actual speed emphasized.

802.1X authentication - verify access to secure networks using 802.1X and MAC Access Control Lists (ACL). The included LinkRunner G2 Manager software configures 802.1X EAP type, downloads certificates and enters passwords.

IPv4/IPv6 ready - supports both IPv4 and IPv6 networks.

IP Address Validation - a key element to ensure network services are available for IoT connected devices is to verify they are able to obtain an IP address and access the network. Both DHCP and static IP configurations are supported; when using DHCP, the handshake timing and lease time is shown.

Key device and application availability -in addition to ping, which is sometimes blocked or disabled, the LinkRunner G2 can perform a TCP port open test to verify application connectivity to up to 10 user-defined targets using IPv4 and IPv6. Router, DNS and DHCP servers are reported. LinkRunner G2 provides the ability to perform a continuous ping, providing a quick and simple way to find intermittent connectivity issues.

Cable verification - validate patch cables and installed wiring for length, reversed and crossed pairs, as well as distance-to-fault for opens, shorts, and split pairs. Perform a patch cable test with the integrated loopback ports, simply plug each end of the patch cord into the two RJ-45 ports on LinkRunner G2 to see pin to pin connectivity. Cable toning, flash port and numbered WireView adapters (for cable identification and wiremap) are also supported.

Automated Results Documentation - use the encrypted and highly secure Link-Live results management database to manage an unlimited number of test results, testers claimed to the service and invited users. Easily view and manage results such as by job-specific folders, tags and organizations. Results can include more detailed information such as jack location, trouble ticket, photographs taken with the integrated camera, or data from a QR/barcode scan. Create professional reports customized with your logo and project-specific information. Know who on your staff is testing what, where and when.

Packet Reflector - The LinkRunner G2 packet reflector mode allows it to be used as a remote device during end-to-end network path performance tests to validate LAN and WAN throughput capabilities up to 1000BASE-T. The reflector mode can be configured to swap MAC and/or IP addresses.

LinkRunner G2 supports packet reflection for:
