C9400-LC-24S – Catalyst 9400 Module

The C9400-LC-24S is a line card for the Cisco Catalyst 9400 Series switches, designed to provide high-density, high-performance connectivity for enterprise and service provider networks. This line card offers 24 ports of 10 Gigabit Ethernet (10GE) or 25 Gigabit Ethernet (25GE) connectivity and supports line-rate forwarding at up to 10 Gbps per port for 10GE and up to 25 Gbps per port for 25GE.

Here are some of the key features and benefits of the C9400-LC-24S:

High-density connectivity

The C9400-LC-24S provides 24 ports of 10GE or 25GE connectivity, allowing organizations to connect a large number of devices and support high-bandwidth applications.

Line-rate forwarding

The line card supports line-rate forwarding at up to 10 Gbps per port for 10GE and up to 25 Gbps per port for 25GE, ensuring that network traffic is forwarded at maximum speed without any delay.

Flexible port configuration

The line card offers 24 SFP28 ports for 25GE connectivity or 24 SFP+ ports for 10GE connectivity. The ports support auto-negotiation and auto-MDI/MDIX, making it easy to connect to a wide range of devices.

Redundancy and high availability

The C9400-LC-24S supports hitless ISSU (In-Service Software Upgrade), which allows software upgrades to be performed without any disruption to network traffic. The line card also supports redundant power supplies and fans, ensuring that the switch remains operational even in the event of a component failure.

Quality of Service (QoS) and traffic management

The line card supports IEEE 802.1p CoS (Class of Service) and DiffServ (Differentiated Services) with up to eight queues per port. It also supports Weighted Round Robin (WRR), Strict Priority (SP), and a combination of both for traffic scheduling, allowing organizations to prioritize critical applications and ensure quality of service.

Security and management

The C9400-LC-24S supports MACsec (Media Access Control Security) for securing data in transit over Layer 2 connections and Cisco TrustSec for secure access and policy enforcement. The line card can be managed using Simple Network Management Protocol (SNMP), Syslog, and Cisco IOS Software-based management.

In summary, the C9400-LC-24S line card provides high-density, high-performance connectivity for the Catalyst 9400 Series switches, with flexible port configuration, advanced QoS and traffic management features, and a redundant design for high availability. It is an ideal choice for organizations that require high-speed and secure connectivity for their network infrastructure.
