Cisco C9600X-LC-32CD | Catalyst 9600 Line Card, 30-Port 100G, 2-Port 400G QSFP-DD

Q: Which supervisor engine is required for the C9600X-LC-32CD line card?
A: This line card is compatible exclusively with the Cisco Catalyst 9600X-SUP-2 Supervisor Engine, which provides 3.2 Tbps full-duplex bandwidth. It is not supported with the older C9600-SUP-1 supervisor.

Q: What is the total bandwidth capacity of this line card?
A: When paired with the C9600X-SUP-2 supervisor, the C9600X-LC-32CD provides up to 6.4 Tbps per slot capacity with non-blocking performance across all 30 100G ports and 2 400G ports operating simultaneously at full line rate.

Q: Does this line card support MACsec encryption?
A: Yes, the C9600X-LC-32CD features CDR5M PHY technology that provides both LAN MACsec and WAN-MACsec encryption at line rate when used with the C9600X-SUP-2 supervisor and appropriate licensing.

Q: What are the typical deployment scenarios for this line card?
A: This line card is designed for high-density campus core deployments, data center aggregation layers, and large enterprise edge networks requiring 100G aggregation from access switches and 400G uplinks to spine or data center switches.

Q: Can I use different port speeds on the same line card?
A: Yes, port speeds are auto-negotiated based on the inserted optical transceiver. The QSFP28 ports support 100G/40G, while the QSFP-DD ports support 400G/200G/100G/40G, providing deployment flexibility for mixed-speed environments.
