Cisco Catalyst 9400 Series 24-Port 10 Gigabit Ethernet SFP+ Line Card (C9400-LC-24XS)

Deliver up to 480 Gbps of full-duplex switching capacity with the Cisco Catalyst 9400 Series 24-Port 10 Gigabit Ethernet SFP+ line card. Built for enterprise campus cores and high-density aggregation, this module equips Catalyst 9400 chassis with twenty-four wire-rate 10GbE SFP+ ports, advanced Layer 2/3/4 services, and hardware-accelerated security.

Overview

The C9400-LC-24XS is a hot-swappable line card for Cisco Catalyst 9400 Series switches, including the 4-slot, 7-slot, and 10-slot chassis. It provides 24 ports of 10 Gigabit Ethernet via SFP+ transceivers, supporting both fiber and copper connectivity options. With a forwarding bandwidth of up to 240 Gbps full-duplex and a switching capacity of 480 Gbps, it handles demanding workloads such as high-speed data center interconnects, campus distribution, and core networking. The card runs Cisco IOS XE and is managed through the supervisor engine, ensuring consistent policy and feature support across the chassis.

What stands out

• 24 ports of 10 Gigabit Ethernet SFP+ for flexible, high-speed uplinks and server connectivity.
• Hot-swappable design allows insertion and removal without disrupting the chassis or other line cards.
• Extensive security with MACsec encryption, Access Control Lists (ACLs), and Cisco TrustSec.
• Advanced QoS for granular traffic prioritization, ensuring voice, video, and critical applications perform optimally.
• Support for jumbo frames up to 9198 bytes, improving throughput for large data transfers.
• Large MAC address table of up to 128,000 entries, suitable for large-scale Layer 2 domains.
• High reliability with an estimated MTBF of over 400,000 hours.
