High-precision timestamping

The Cisco Nexus® 3550-F Fusion HPT is a high-precision network tapping, aggregation, and monitoring solution, optimized for high-performance, low-latency networks.

The device incorporates our world-leading HPT1 time-stamping technology, for industry-leading 100ps (0.1ns) timestamps that are embedded in every packet. This makes the Cisco Nexus 3550-F Fusion HPT the highest-precision network aggregation and monitoring solution available on the market. The device also offers high-quality time synchronization to pulse-per-second (PPS), GPS, and Precision Time Protocol (PTP) sources, ensuring that every packet is globally synchronized as well as precisely timestamped.

High-bandwidth ingress and egress

The system offers 400Gb/s of ingress and configurable egress options of up to 80Gb/s.

This ensures that tap aggregation continues to perform well even under adverse network conditions. The device supports up to 40 ingress ports operating at 1Gb/s2, 10Gb/s, or 40Gb/s2 (400Gb/s total), with HPT timestamps at 100ps resolution. Egress is supported through between 1 and 8 ports operating at 10Gb/s each, or 1 to 2 ports operating at 40Gb/s2 each. Egress ports also feature industry-standard Ethernet flow control, to allow lossless transmission even when capture devices are congested.

Deep packet buffer hierarchy

A deep, multilayered packet buffer architecture provides robust micro-burst protection.

Correlated micro-bursts are a fact of life, especially in high-performance networks. Yet regulatory environments require that every packet be captured. The Cisco Nexus 3550-F Fusion HPT has a deep packet buffer hierarchy to ensure that packets are captured, time stamped, and transferred to long-term storage, even under extreme correlated micro-burst scenarios. It offers 32kB per-port buffers, 64kB per-quad-port buffers, and 32GB of global packet buffering (see figure overleaf). This multilayer architecture makes the Cisco Nexus 3550-F Fusion HPT the most reliable tap aggregation system available.

Transparent tapping

Replace 20 optical taps with a single 1RU device

Optical taps are difficult to deploy and manage, and consume large amounts of rack space. Every ingress port on the Cisco Nexus 3550-F Fusion HPT can be configured as a Layer 1 tap, allowing the device to replace 20 optical taps in a single 1RU of rack space. Cisco Nexus 3550-F HPT taps are transparent to other devices. They add less than 5ns of delay to the tapped path, and nearly undetectable jitter.

Ease of use and manageability

Ease of use and enterprise manageability features are core to the Cisco Nexus 3550-F Fusion range.

Many users rate our CLI as one of the best they have operated. Every command available on the CLI is also available via a remote JSON RPC API. This makes the device easy to operate and to manage at scale. All Cisco Nexus 3550-F devices include standard enterprise manageability and deployability features, including automatic configuration (via DHCP), SNMP, TACACS+ authentication, onboard Python programmability, BASH shell access, and time-series logging.
