LinkRunner 100G Network Tester

The LinkRunner 100G is the industry’s smallest and lightest handheld tester for installing, verifying, and maintaining Ethernet networks from 25G to 100G. It puts the physical-layer visibility that once required a cart of modular test equipment historically $25,000 or more directly into the hands of the engineer holding the ticket, at a fraction of the cost. At 25G per lane, a marginal connector can degrade a link quietly enough that switch counters still read clean, and a mismatched setting can prevent the establishment of a link with no error apparent. The LinkRunner 100G is built to catch exactly that before it becomes an outage.

• Prove your network delivers the performance you’re paying for.
• Validate fiber and optics before they become a 2:00 am call.
• Get evidence, not assumptions, every time you test.

Key features

• Instant Network Visibility at Line Rate
  In seconds, AutoTest verifies the connected switch port and its configuration, validates link speed and key network services, giving you immediate clarity and confidence.
   
•  Proof of Performance, Not Assumptions¹
  Validate true capacity and quality of transmission end-to-end, with measurable, repeatable Layer 3 performance results, so your network delivers what it promises.
   
• Real-World Validation of QSFP28 Optics
  Test with the same optics and transceivers your production network uses, for true end-to-end verification with zero deployment surprises.
   
• QSFP28 Insights
  Automatically detects and validates module type, speed, FEC settings, and interface configuration across 25G, 40G, 50G, and 100G optics single-mode, multi-mode, trunks, LC breakouts, and MTP/MPO links, so you know exactly how every module is set to operate.
   
• Consolidated, Professional Reports
  Automatically generate documentation that consolidates every test result optical configuration, performance metrics, and link validation into one clear report you can share with management or clients.

¹ Two LinkRunner 100G units are required for the network Performance Test

Capabilities beyond the Physical Layer

• Path Analysis
  Maps the hop-by-hop switch and router path to any connected device, surfacing overloaded interfaces, saturated device resources, and interface errors along the way — breaking through the “visibility ceiling” between wired segments to show exactly where a path degrades.
   
• EZ Wired
  Identifies the nearest connected switch using LLDP, CDP, and EDP, and pulls its critical configuration — port name, link speed/duplex, and VLAN assignment
   
• Ally Intelligence*
  NetAlly’s expert system reads your test results and returns plain-language root-cause analysis and next steps— so less time goes into interpreting data and more into closing the ticket.
   
• Discovery & Topology Mapping*
  Discovers devices and endpoints across multiple VLANs and generates topology maps in Link-Live surfacing configuration changes and flagging “suspect” devices for investigation.
   
• Rogue Device Identification*
  Runs Discovery and Nmap scans to identify every device on the network, then validates open services, configurations, and potential security exposures — flagging devices that don’t belong before they become an incident.
   
• Link-Live™
  NetAlly’s cloud collaboration, reporting, and analysis platform:  very test result from every handheld tester and analyzer on your team logs here automatically, so results, topology maps, and remediation history stay in one place instead of scattered across laptops.

*AllyCare-enabled features include Advanced Topology Mapping in Link-Live, Rogue Device Identification, Ally Intelligence, and Remote View & Control; these features are only available to customers with AllyCare Pro support.
