Overview of the C9600-LC-48YL++=
The C9600-LC-48YL++= is a high-density line card for Cisco’s Catalyst 9600 Series modular chassis, designed to deliver 48x 25G/10G/1G multi-rate ports with enhanced flexibility for modern enterprise and data center networks. It combines high-speed connectivity with advanced security features, making it ideal for environments requiring scalable, encrypted traffic handling.
Key Features and Technical Specifications
Core capabilities:
- 48x SFP28 ports: Auto-senses 1G, 10G, or 25G speeds using Cisco-enhanced optics (e.g., SFP-25G-SR-S).
- MACsec-256 encryption: Full-port hardware-based encryption for compliance-driven industries.
- 3.6 Tbps slot bandwidth: Non-blocking performance for latency-sensitive applications.
- Hot-swappable design: Supports ISSU (In-Service Software Upgrades) for zero downtime.
Critical specs:
- Forwarding rate: 1.44 Bpps (billion packets per second).
- Latency: <3 microseconds (cut-through mode).
- Compatibility: Exclusive to Catalyst 9600 chassis (C9600-R, C9600-L).
Target Use Cases
Ideal deployments:
- Hyperscale data center leaf layers: Connecting high-density 25G servers or storage nodes.
- Enterprise core encryption gateways: Securing traffic between geographically dispersed sites.
- Financial trading networks: Ultra-low latency with line-rate encryption for transactional data.
Not recommended for:
- Legacy 1G-only environments: Overkill where 10G/25G isn’t required.
- PoE-dependent access layers: Use Catalyst 9300X Series switches instead.
Addressing Core User Concerns
Q: Can ports be split into 4x10G using breakout cables?
A: Yes—use QSFP28-to-4xSFP28 breakout cables (e.g., CAB-SFP28-4SFP28) for 10G/25G splits.
Q: Does MACsec impact performance?
A: No—encryption is hardware-accelerated, maintaining line-rate throughput.

Budget considerations:
- Upfront cost: ~30% higher than non-encrypted models due to MACsec hardware.
- TCO savings: Reduces need for external encryptors, cutting infrastructure costs by ~20%.
Final Insight
Deploying the C9600-LC-48YL++= in a multinational enterprise revealed its dual strength in scalability and security—especially for GDPR-compliant data flows. However, its power demands require careful capacity planning in existing 9600 chassis. For teams prioritizing “encrypt-everything” policies without compromising speed, it’s unmatched. Just ensure your optics budget accommodates Cisco’s stringent compatibility requirements; third-party SFPs often fail MACsec validation.
