The C9400-LC-24S Cisco Catalyst 9400 Series LC 24 Ports 1 Gigabit Ethernet (SFP) Expansion Module is designed to provide high-performance and scalable connectivity for enterprise networks. This expansion module provides 24 ports of 1 Gigabit Ethernet connectivity, each supporting SFP transceivers, which can be used for both copper and fiber connections.
Performance: The C9400-LC-24S provides wire-speed performance for all 24 Gigabit Ethernet ports, meaning that the module can forward traffic at the full line rate of 1 Gbps for each port simultaneously. This high performance is achieved through the use of advanced ASICs (Application-Specific Integrated Circuits) that are optimized for forwarding network traffic quickly and efficiently.
Scalability: The C9400-LC-24S expansion module is designed to be highly scalable, allowing it to be used in large enterprise networks that require a high number of network connections. The Cisco Catalyst 9400 Series chassis can support up to 10 of these modules, providing up to 240 Gigabit Ethernet ports in a single chassis. This high level of scalability allows the network to grow and evolve as the organization expands.
Security FeaturesThe Cisco Catalyst 9400 Series LC 24 Ports 1 Gigabit Ethernet (SFP) Expansion Module (C9400-LC-24S) is a high-performance networking module designed for the Cisco Catalyst 9400 Series Switches. The module provides 24 ports of 1 Gigabit Ethernet connectivity using Small Form-Factor Pluggable (SFP) transceivers. In terms of security features, the C9400-LC-24S offers the following:
- Access Control Lists (ACLs): ACLs provide a way to filter traffic based on various criteria, such as source and destination IP addresses, protocols, and port numbers. ACLs can be used to control access to network resources and to protect against various types of attacks, such as denial-of-service (DoS) attacks.
- Port Security: This feature allows you to restrict access to switch ports based on the MAC address of the device connected to the port. You can specify the maximum number of MAC addresses allowed on a port and configure the switch to automatically shut down the port if the number is exceeded.
- Dynamic ARP Inspection (DAI): DAI is a security feature that helps prevent ARP spoofing attacks by validating ARP packets before forwarding them. DAI maintains a mapping of IP addresses to MAC addresses and drops any ARP packets that contain invalid information.
- Secure Shell (SSH) Protocol: SSH is a cryptographic network protocol that provides secure remote access to network devices. The C9400-LC-24S supports SSH version 2, which provides strong encryption and authentication.
- Network Admission Control (NAC): NAC is a security framework that provides pre-admission control and post-admission control over network resources. The C9400-LC-24S supports NAC and can enforce policies to ensure that only compliant devices are allowed access to the network.
- Private VLANs: Private VLANs provide a way to isolate traffic within a VLAN by restricting communication between hosts. The C9400-LC-24S supports private VLANs and can be used to protect against various types of attacks, such as VLAN hopping.
- Encrypted Traffic Analytics (ETA): ETA is a security feature that provides visibility into encrypted traffic by analyzing network flows and identifying potential threats. The C9400-LC-24S supports ETA and can help protect against various types of attacks, such as malware and command-and-control (C2) traffic.
The C9400-LC-24S is an expansion module for the Cisco Catalyst 9400 Series switches, which provides an additional 24 ports of 1 Gigabit Ethernet connectivity through Small Form-Factor Pluggable (SFP) transceivers. To install and set up this module, follow these instructions:
- Ensure that the switch is powered off before installing the module.
- Locate an available module slot on the switch and remove the filler panel from the slot by pressing the release latch.
- Align the module with the slot and gently slide it into place, making sure that the connectors on the module align with the connectors inside the slot.
- Push the module firmly into the slot until it clicks into place.
- Repeat the process for any additional modules that need to be installed.
- Power on the switch and verify that the module is recognized by the switch. You can do this by checking the switch's interface status or by using the command line interface (CLI) to verify the module's presence.
- Configure the new interfaces as needed using the switch's management interface, such as the CLI or web-based interface.
