Cisco WS-C4500X-16SFP+ Switch: Scalable Solutions for Mid-Sized Enterprises

May 24 , 2025 7

1. Technical Specifications & Performance Overview

The Cisco WS-C4500X-16SFP+ is a versatile, fixed-configuration switch optimized for mid-sized enterprise networks:

• Switching Capacity: 176 Gbps (non-blocking wire-speed performance)

• Forwarding Rate: 130.95 Mpps (ideal for converged voice/data/video workloads)

• RAM: 4 GB (expandable via dual DIMM slots)

• Storage: 8 GB Flash memory (supports IOS upgrades and network applications)

• Ports: 16 x 10 Gigabit SFP+ ports (fiber-optic ready) + 4 x 1 Gigabit Ethernet ports

Performance vs. Competitors:

• Delivers 20% higher 10G port density than the Cisco WS-C3850-48F-S.

• Matches Arista 7280R switches in IPv6 routing scalability but at a lower cost.

2. Core Functionalities

• Layer 2/3 Flexibility: Static routing, OSPF, and BGP support for hybrid networks.

• Advanced QoS: Granular traffic prioritization for VoIP, video conferencing, and IoT.

• Security: Integrated Cisco TrustSec, 802.1X authentication, and storm control.

• Redundancy: Hot-swappable power supplies and fans ensure 24/7 uptime.

  
  

3. Design & Engineering

• Modular Architecture: Supports supervisor engine upgrades for future scalability.

• Fanless Option: Silent operation for environmentally sensitive deployments.

• Compact Form Factor: 1RU chassis optimized for space-constrained data centers.

• LED Diagnostics: Real-time port status monitoring via intuitive front-panel indicators.

4. User Experience & Management

• Streamlined CLI/GUI: Web-based GUI (Cisco Prime Infrastructure) simplifies configuration.

• Automation-Ready: RESTCONF/YANG APIs for Ansible/Cisco NSO integration.

• Zero-Touch Provisioning (ZTP): Auto-configures new switches via PXE or USB.

5. Pricing & Cost Efficiency

• List Price: ~$14,000 USD (varies by licensing and feature bundles).

• TCO Advantage: 5-year warranty covers hardware failures; energy-efficient design reduces operational costs.

• ROI Focus: Scalability minimizes upgrade frequency compared to fixed-port models.

6. Power Consumption

• Max Power Draw: 450W (dual redundant PSUs).

• Energy Star Compliance: 80 PLUS Platinum certification for reduced electricity usage.

7. Compatibility & Integration

• Cisco Ecosystem: Certified with UCS servers, ACI fabrics, and Firepower NGFW.

• Multi-Vendor Support: Works with VMware NSX, OpenStack, and AWS Transit Gateway.

• Legacy Bridges: Supports CiscoWorks and Prime Infrastructure for older deployments.

8. Software Ecosystem

• Native Features: NetFlow, SPAN, and VXLAN for network overlays.

• DNA Center Integration: Simplifies network segmentation and policy enforcement.

• Lifecycle Management: Automatic updates via Cisco Smart Licensing.

9. Typical Use Cases

• Data Center Aggregation: Connects spine switches in CLOS architectures.

• Campus Backbone: Consolidates traffic from multiple access-layer switches.

• Cloud-Ready Networks: Supports SDN and NFV deployments.
