Description

The Cisco C9600-LC-40YL4CD is a high-density modular line card designed for Catalyst 9600 Series chassis, delivering flexible campus core and distribution connectivity. With 40 multi-rate SFP56 ports supporting 50G/25G/10G/1G speeds and integrated uplinks of 2x QSFP56 (200G) and 2x QSFP-DD (400G), this card eliminates the need for separate uplink modules. Compatible with both C9600-SUP-1 and C9600X-SUP-2 supervisor engines, it provides scalable bandwidth up to 3.2 Tbps per slot, making it ideal for enterprise networks requiring high-density aggregation with future-ready performance.

FAQs

Q: What is the difference in performance between the two supervisor engines?
A: With C9600X-SUP-2, this line card delivers full 50G capability on all 40 SFP56 ports, 2x 200G QSFP56, and 2x 400G QSFP-DD uplinks with 3.2 Tbps bandwidth. With C9600-SUP-1, SFP56 ports are limited to 25G maximum, QSFP-DD ports support up to 100G, and total bandwidth is 1.2 Tbps.

Q: Can this line card work in both C9606R and C9610R chassis?
A: Yes, the C9600-LC-40YL4CD works natively in the C9606R chassis. For C9610R chassis, you need the C9610-LC-ADPT adapter to install this line card.

Q: What types of optics are supported on this line card?
A: The 40 SFP56 ports support SFP56, SFP28, and SFP+ transceivers for various speeds. The 2 QSFP56 ports use QSFP28 and QSFP56 optics, while the 2 QSFP-DD ports support QSFP-DD and backward-compatible QSFP56/QSFP28 modules. Both Cisco-branded and compatible third-party optics are supported.

Q: Does this line card support MACsec encryption?
A: Yes, when paired with the C9600X-SUP-2 supervisor engine, this line card supports hardware-based MACsec 256-bit encryption and WAN MACsec (with HSEC license). MACsec is not available when using C9600-SUP-1.

Q: What licensing is required for this line card?
A: The line card requires a Cisco software subscription license at the chassis level (Network Advantage, DNA Advantage, or Catalyst subscription). The hardware itself does not require a separate license, but advanced features like WAN MACsec require the HSEC add-on license with C9600X-SUP-2.
