About This Product

Overview

Cisco C9550 Series Smart Switches deliver high-throughput Ethernet switching and integrated security for enterprise core and aggregation networks.

Built on Cisco Silicon One Application-Specific Integrated Circuits (ASICs), the Cisco C9550 Series Smart Switches provide high-density Small Form-Factor Pluggable (SFP) downlink ports up to 50 Gigabit Ethernet (50G) and Quad SFP (QSFP) uplink ports up to 400G, or consistent QSFP ports up to 100G. By combining hardware switching and routing into a single platform, you can reduce infrastructure complexity and cost. Integrated security capabilities include continuous zero-trust security, inline threat protection with Cisco Live Protect, and hardware support for post-quantum cryptography (PQC) algorithms and encryption to address emerging decryption risks. These capabilities enable organizations to safeguard against future attacks using quantum computers and offer protection against zero-day attacks on software vulnerabilities.

Cisco C9550 Series Smart Switches simplify IT operations by unifying hardware, software, and support, regardless of how you choose to manage your network.

  • Unified hardware: Common hardware designed to support any management mode
  • Unified licensing: Common licensing that unlocks advanced features and capabilities across platforms
  • Unified support: Consistent and reliable product support for both hardware and software included with the unified licenses

Series highlights

The Cisco C9550 Series Smart Switches provide fixed enterprise core and aggregation switching for enterprise networks that span campuses, branch, and cloud environments. They support secure connectivity for distributed users, diverse device types, and applications deployed across on-premises and cloud infrastructure.

C9550 Series key features and benefits

Unified experience: Cisco C9550 Series Smart Switches use a single hardware platform, licensing model, and support framework across cloud, on-premises, and hybrid deployments. This simplifies deployment, reduces configuration errors, and enables consistent operations across environments.

Performance and scalability: This platform delivers up to 6.4 Tbps of switching bandwidth and supports dense port configurations, including, Up to 96 SFP56 ports (50/25/10/1G), Up to 4 QSFP-DD ports (400/100/40G), Redundant, Titanium-rated power supplies and field-replaceable fan options support continuous operation in high-demand environments.

Security and cryptography: The platform enforces security at scale with, Hardware access control lists (ACLs), Segmentation using VXLAN and Cisco TrustSec, Up to 100G IPsec and line-rate MACsec encryption, Advanced Encryption Standard, AES-GCM-256 encryption, It supports inline threat detection and response, including zero-day attack mitigation and increased OS resiliency with Cisco Live Protect and hardware PQC against emerging quantum-based attacks.

  • Ethernet Switch supports network continuity by maintaining data transmission during operation
  • Gigabit Ethernet supports higher uplink data rates compared to standard Ethernet server connections
  • Layer 2 switching supports defined functions including IGMP snooping, port mirroring, and spanning tree operation
  • Rack?mountable design supports installation within standard equipment racks to accommodate organized hardware placement
  • Management capability enables control over network setup and configuration according to operational requirements
  • Optical fiber support enables network connections across longer distances for data transmission between network components
  • Built?in power supply supports internal components by providing required operating voltage
  • Allows connection between separate networks to support infrastructure flexibility and structured traffic distribution
  • Stack port supports data communication between stacked devices within a network configuration
