The SierraNet M1288 offers the most cost effective, advanced and fully integrated Ethernet and Fibre Channel data capture and protocol verification systems available for developers and protocol test engineers. The M1288 protocol analysis systems provide engineers with 100% recording of all Fibre Channel and Ethernet related traffic at full line rates and offers the addition of error injection and traffic corruption with our InFusion™ tools for advanced validation and verification testing.

The SierraNet M1288 hardware platform and Net Protocol Suite graphical user interface provides the highest level of performance and flexibility available in the market for legacy and emerging high-speed network and fabric deployments.

The SierraNet M1288 brings analysis and verification of traditional or converged Ethernet and Fibre Channel products in a single platform. The integrated QSFP-DD connections support Ethernet rates – 25GbE, 50GbE, 100GbE, 200GbE, 400GbE link traffic – for both analysis and jamming applications and 800GbE for analysis.

Each SFP112 pair can probe and/or jam Fibre Channel 128G FC/link on copper or optical cabling and eliminates the need for separate "single function" blades, pods, or adapters found in some competitive products providing a highly compact, extremely flexible, multi-function protocol analyzer.

The SierraNet M1288's sophisticated analysis and jamming software, the Net Protocol Suite, provides unmatched flexibility with customized data displays that easily identify and navigate to specific events of interest quickly. Decoding in the Net Protocol Suite's multiple trace views provide superior visibility for troubleshooting low level to application layer issues, decode per the supported specifications and their associated encoding schemes, and the zero-time search and filter capabilities easily find Ethernet and Fibre Channel events in a contextual and intuitive way.

In a multi-protocol environment, Teledyne LeCroy's CrossSync™ can synchronize and correlate traces with our other leading protocol analysis tools, such as the PCI Express Summit analyzers, to understand how traffic, stimulus, and/or errors propagate across bridges or adapters.

The Teledyne LeCroy InFusion™ (Jammer) Error Injector and Traffic Modifier tool allows users to verify real-world fault handling for both Ethernet network and Fibre Channel fabric systems.  InFusion sits in the data path on a live system to programmatically alter or corrupt traffic. InFusion is the ideal tool for stress-testing systems using actual workloads and devices that are often missed using simulated workloads.

SierraNet InFusion supports Ethernet link speeds from 25GbE up to 400GbE and Fibre Channel links up to 128 Gbps, depending on the capabilities of the licensed SierraNet platform. InFusion monitors traffic from both directions in real-time and using customer defined parameters, replaces or modifies any bit, ordered-set, checksum, or other parameters with those specified for the test case.

InFusion can change traffic when it detects a specific sequence or reaches a designated time interval, yet it requires no complicated scripts, programming, or simulation tools. InFusion can monitor traffic in both directions and act on events occurring in either direction of the communications link. InFusion can even modify bi-directional traffic within a given test scenario, either from the Originator or from the Responder. InFusion is specifically designed to verify recovery characteristics within a subsystem. An easy, user-friendly menu interface with icons and hyperlinks allows you to create specific test Scenarios in just minutes.

Once an InFusion session starts, the system automatically handles protocol handshaking between devices. InFusion transmits a faithful copy of the original data stream down to the CRC value which, if needed, it recalculates. InFusion allows test engineers to systematically verify error recovery in ways not possible with other test platforms.

Key Features:

• Error Injection: Injects CRC, disparity, PCS encoding (8b/10b, 64/66b, 544/514 etc.) framing, and coding errors.
• Break Link Recovery: Programmatically breaks the connection to test link recovery.
• Value Replacement: Monitors the link for specific values, patterns, or ordered-sets (as low as bit level) and replaces with user-defined values. You can replace values on every occurrence, after a specified or random number of occurrences, or after a specified time interval.
• Packet Drop: Removes individual ordered-sets or frames from the stream to verify retry behavior.
• Packet Delay: Captures an individual frame and re-inserts into the data stream to verify out-of-order reassembly.
• Ordered-set Manipulation: Replaces handshaking and flow control ordered-sets to help validate robustness of a design.
• Traffic Monitoring: Operates as a traffic monitor, collecting statistical data on user-specified parameters. In this mode, data passes unchanged in both directions.
• Menu-Driven Interface: Allows easy set-up of test Scenarios.

With respect to traffic modification, in the Link Layer you can modify ordered-sets, CRC, scrambled data, and connection Events. InFusion test scripts are called Scenarios. Scenarios determine how the hardware device monitors and modifies line traffic. To create and download Scenarios the Teledyne LeCroy Net Protocol Suite application must be used.

Networks or Fabrics under examination are connected to the M1288 through either Small Form Factor Pluggable-112 (SFP 112) connectors, or Quad-Small Form Factor Pluggable Double Density (QSFP-DD) connectors.

Teledyne LeCroy SierraNet M1288 provides multiple options for capturing your Ethernet links effectively through Teledyne LeCroy's TAP6 technology. The TAP6 from Teledyne LeCroy allows for the most efficient method for capturing the signal without impacting the link stability. In order to support both enterprise and hyperscale test environments the M1288 Analog Passthrough Probes feature flexibility connectivity options including QSFP-dd and OSFP endpoints. For additional flexibility the M1288 also offers capture through digitally retimed ports. These ports allow for complete flexibility of capture, analysis, and the ability to inject errors into the stream for full system validation of copper and optical Ethernet links.

The Probes enable all lanes and all levels of traffic to pass through unchanged between the two devices as well as sending the all the traffic to the M1288 Analyzer to enable wire level capture. They support the PAM4 signaling requirements and NRZ signal speeds. The probes come with attached 1/2m DAC cables in either QSFP-DD or OSFP form factors. The OSFP cables come with changeable fins to support both finned OSFP cages and RHS cages.

Users may daisy-chain multiple SierraNet platforms to examine higher port counts and analyze captured traffic across all systems in a single, easy to understand Net Protocol Suite™ trace view.

Speed Negotiation: Each device sends a list of its data-rate capabilities to its link partner. They then agree on the highest common data rate1.

Training the Link: The devices adjust their transmitter and receiver settings to optimize the signal quality. This involves examining the signal and requesting adjustments be made to equalization settings until the signal is good enough.

Normal Data Transmission: Once the link is trained, the devices start transmitting normal data traffic using the optimized settings1.

Key Features of Link Expert for Ethernet
Auto Negotiation:

• Test that all speeds can be negotiated to support backward compatibility.
• Perform both positive and negative FEC settings, specifying which FEC settings should be used and which ones are not allowed.
• Test with and without fallback speeds enabled, ensuring configurations are set correctly for both scenarios.

Link Training

• Test whether links can be established starting from any preset to avoid using marginal presets.
• Assess the reliability of link bring-up for each preset to verify the algorithm consistently arrives at stable settings.
• Test with and without fallback speeds enabled, ensuring configurations are set correctly for both scenarios.
