Description

Cisco Nexus3550F Dubai

The Cisco Nexus3550F Dubai Fusion (formerly ExaLINK Fusion) represents a remarkably versatile top-of-rack switch characterized by a unique and modular architecture. Engineered for low-latency operations, it enables swift 95ns switching, 39ns forwarding and aggregation, and sub 5ns layer 1 patching and tapping, all within a single device. Its extensible design is underscored by two internal module bays that are seamlessly interconnected via a high-speed, reconfigurable layer 1 switch, allowing for the deployment of both Cisco-developed firmware and customer-developed logic directly to the FPGA itself.

Positioned as a High Precision Timestamping Switch, the Cisco Nexus3550F Dubai serves as an advanced network tapping, aggregation, and monitoring solution, specially optimized for high-performance, low-latency networks. Leveraging Cisco’s cutting-edge HPT time-stamping technology, the device achieves 70-picosecond (70ps) timestamps embedded within every packet. This distinctive feature positions the Cisco Nexus 3550-F HPT as the most precise network aggregation and monitoring solution available in the current market landscape. Additionally, the switch offers impeccable time synchronization to Pulse-Per-Second (PPS), GPS, and Precision Time Protocol (PTP) sources, guaranteeing that every packet is globally synchronized while maintaining precise timestamps.

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.
