Description

Cisco Nexus3550F Dubai

The Cisco Nexus3550F Dubai Fusion, formerly known as ExaLINK Fusion, stands out as a uniquely flexible top-of-rack switch featuring a modular architecture. As a low-latency switch, it supports rapid switching at 95ns, forwarding and aggregation at 39ns, and sub-5ns layer 1 patching and tapping – all within a single device. Its distinctive design includes two internal module bays interconnected via a high-speed, reconfigurable layer 1 switch, allowing the deployment of both Cisco-developed firmware and custom-developed logic directly to the FPGA.

Specifically designed for high-performance, low-latency networks, the Cisco Nexus3550F Dubai High Precision Timestamping Switch serves as a network tapping, aggregation, and monitoring solution. It incorporates Cisco’s industry-leading HPT time-stamping technology, providing 70-picosecond (70ps) timestamps embedded in every packet. This positions the Cisco Nexus 3550-F HPT as the highest-precision network aggregation and monitoring solution available in today’s market. The switch also ensures high-quality time synchronization to Pulse-Per-Second (PPS), GPS, and Precision Time Protocol (PTP) sources, ensuring global synchronization and precise timestamping for every packet.

Features

Scalable modular architecture

The Cisco Nexus3550F Dubai products are built with a unique modular architecture that scales with your network. Three-line card bays provide the flexibility to grow and change connectivity options over time, while two internal module bays allow the device to be upgraded with expanded functionality, adding new capabilities and extending the useful life of the product.

Ease of use and manageability

The Cisco Nexus3550F Dubai use a custom operating system and Command Line Interface (CLI), designed specifically to address the needs of layer 1 switching and low latency FPGA configuration. Every command available on the CLI is also available via a remote JSON RPC API making this device easy to operate and manage at scale.

Transparent tapping

Network monitoring is vital for logging, debugging and compliance. While optical taps can be used for low latency network inspection, they consume valuable rack space and cannot be remotely managed. The Cisco Nexus3550F Dubai Layer 1 Matrix Switch replaces 16 optical taps (48 ports) in a single 1RU device. Taps through the Cisco Nexus3550F Dubai Modular Layer 1 Matrix Switch employ active signal regeneration so that the signal quality remains high while port-to-port latencies are as low.

An electronic patch panel

Network reconfiguration is a fact of life, yet colocation access is often expensive and sometimes impossible (for example, during business hours). The Cisco Nexus3550F Dubai Modular Layer 1 Matrix Switch offers a fast and convenient tool for managing and reconfiguring a physical network, remotely and at any time of the day, yet adds nearly no overhead. The remote JSON RPC API allows for such changes to be simply automated and controlled by a logically central controller.

Packet-aware statistics and monitoring

Although the Cisco Nexus3550F Dubai Modular Layer 1 Matrix Switch operates at the physical layer, it is fully packet aware. Every port on the device is monitored for vital packet statistics including the number of packets/bytes transmitted/received and transmit/receive errors. The device also provides deep diagnostics including light levels, operating temperatures, transceiver capabilities, and more. All these statistics are available at no latency cost on the critical path.
