Cisco C9600-LC-48YL | Catalyst 9600 48-Port 25G Line Card, 2.4 Tbps, SFP28/SFP+

Q: Which supervisor engines are compatible with the C9600-LC-48YL?
A: The C9600-LC-48YL is compatible with both C9600-SUP-1 and C9600X-SUP-2 supervisor engines, providing flexibility for mixed deployments and future upgrades. Note that 50GE speeds and speeds below 10GE have supervisor-specific support requirements.

Q: What port speeds does this line card support?
A: The line card supports 25G, 10G, and 1G Ethernet speeds across all 48 SFP28/SFP+ ports. When paired with the C9600X-SUP-2, it also supports 50GE speeds. Note that 1GE support is only available with C9600-SUP-1, while C9600X-SUP-2 requires SFP-1G-SX or SFP-1G-LH optics for 1Gbps.

Q: What is the typical deployment scenario for this line card?
A: The C9600-LC-48YL is designed for high port-density campus core and distribution layer deployments where fiber connectivity is required. It provides high-speed upstream and downstream connections for aggregating access layer switches or connecting to data center and service provider networks.

Q: Does this line card support MACsec encryption?
A: Yes, the C9600-LC-48YL supports Advanced Encryption Standard 256 (AES-256) with the MACsec-256 encryption algorithm when paired with C9600-SUP-1. MACsec features are inherited from the supervisor engine through the functionally transparent architecture.

Q: Can I hot-swap this line card without shutting down the chassis?
A: Yes, the C9600-LC-48YL is a hot-swappable module, allowing you to add or replace the line card while the Catalyst 9600 chassis remains powered and operational, minimizing network downtime during maintenance.
