Flexibility to Meet Any Debug Challenge

The SierraNet M408 hardware platform and graphical user interface provides the highest level of performance and flexibility available in the market.

The SierraNet M408 employs Teledyne LeCroy's new FlexPort™ technology providing ultimate flexibility in analysis of traditional or converged Ethernet and Fibre Channel products in a single platform and the flexibility to add protocol specific features, functionality, and speed support at the time of purchase or at a later time by simply adding more license keys.Each FlexPort pair can probe both Fibre Channel and Ethernet links of speeds up to 10Gbps for Ethernet and/or 16G FC 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.

In addition to FlexPort technology, the SierraNet M408's new sophisticated analysis 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 Gen3 Summit analyzers, to understand how traffic, stimulus, and/or errors propagate across bridges or adapters.

Versatile, Cost-effective Platform

The SierraNet M408 platform is Compact, Portable, and Light Weight. The SierraNet is currently the Smallest (1U) and lightest (9.5lbs) Fibre Channel and Ethernet protocol analyzer platform in the market, saving valuable real estate and rack space in customer labs and is the best portable solution for engineers on the move.

SierraNet provides users the lowest cost of ownership per engineer, and the lack of maintenance or support fees for subsequent years of operation means strained budgets are not tapped just to keep up with evolving specifications and advancements.

The SierraNet M408 is also the only analyzer in the market with integrated 40Gbps QSFP ports, eliminating the complexity of external "octopus" cables used in some competitive products. The integrated QSFP ports also ensure reliable analysis and error injection by eliminating the risk and associated cost of the additional 8 potential failure points the "octopus" cables create in a test environment.


The SierraNet M408 offers the fastest and most convenient access to the data that engineers need with either a USB3.0 or GE interface. As USB is Plug and Play, this is particularly useful when capturing large amounts of data is necessary, but a quick connection to the analyzer is required, such as at a customer site. In addition to the performance and ease-of-use of the USB3.0 interface, a Gigabit Ethernet Host Interface is also standard on the SierraNet platforms, and the IP Address set-up menus on the front panel eliminate the time and complexity required to configure an analyzer via a null-modem cable and hyper-terminal interface used on competitive products.

The SierraNet M408 also offers the best Time-Stamp Resolution in the market. The SierraNet family has been enhanced with a 1ns time-stamp resolution/accuracy, setting a new industry standard for trace analysis and for timing measurements required for testing high performance SAN products, particularly where latency is a key metric of success.

Additionally, the SierraNet family's Advanced State Machines are easy to use and help Engineers Trigger, Filter, and Inject errors with surgical precision with up to 4 sequencers and up to 24 states per sequencer to concisely target areas of interest and save precious time. When the user can not accurately define the conditions associated with a problem and needs to capture a broad swath of traffic to identify a cause of an issue, the SierraNet can also dynamically assign the largest and most flexible recording memory in the industry to one port or spread the memory use across all eight ports based on the traffic profile.

The Teledyne LeCroy InFusion™ Error Injector and Traffic Modifier is an error injector and traffic modification tool that allows you to verify real‐world fault handling for Fibre Channel systems. InFusion can sit unobtrusively 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.

SierraNet InFusion supports Ethernet links of 10/40G and Fibre Channel links up to 16 Gbps. InFusion monitors traffic from both directions in real‐time and relies on predefined rules to replace any bit, ordered‐set, or parameter with one you specify. 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 modify traffic in only one direction within a given test Scenario, but that direction can be 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, 8b/10b encoding, 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 replace with user‐defined values. You can replace values on every occurrence, after a specified number of occurrences, or after a specified time interval.
  • Packet Drop: Removes individual ordered‐sets or frames from the stream to verify retry behavior.
  • 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. You cannot modify clock skew management and signal integrity. InFusion consists of a hardware device that connects to the line under test and a Windows‐based software application used to create and download test scripts to the device. You also can use the software application to configure and control the device across an Ethernet or USB link. InFusion test scripts are called Scenarios. Scenarios determine how the hardware device monitors and modifies line traffic. In order to create and download Scenarios the Teledyne LeCroy Net Protocol Suite application must be used. For the InFusion connections, the device is connected between the PHYs of the originator and responder.
