The 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.
