The SierraNet M168 is the most cost effective, advanced and fully integrated 10Gbps Ethernet and 16G Fibre Channel data capture and protocol verification systems available for developers and protocol test engineers. The SierraNet M168 is an 8-port multi-protocol analyzer and error injector supporting up to 16G Fibre Channel and 10Gbps Ethernet protocols in a single platform. The SierraNet M168 protocol analysis system provides engineers with 100% recording of all Fibre Channel and Ethernet-related traffic at full line rates on all ports while maintaining the link integrity through non-retimed pass-through probe technology.

Flexibility to Meet Any Debug Challenge

The SierraNet M168 hardware platform and graphical user interface provides the highest level of performance and flexibility available in the market.

The SierraNet M168 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 M168'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 M168 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.


The SierraNet M168 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 M168 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.
