The C3850-NM-2-10G is an expansion module for the Cisco Catalyst 3850-24 switch, which adds two 10 Gigabit Ethernet (10GbE) ports to the switch. This module also includes several security features to enhance the network security of the switch. In this answer, we'll discuss the security features of the C3850-NM-2-10G module.

• Port Security: The C3850-NM-2-10G module supports port security, which allows you to limit the number of devices that can access a port on the switch. You can set up MAC address-based port security on the module, which will only allow devices with approved MAC addresses to connect to the port. Additionally, you can set up static MAC addresses for each port, which ensures that only specific devices are allowed to access the port.
• VLAN Access Control Lists (ACLs): VLAN ACLs allow you to control traffic entering or leaving a VLAN. The C3850-NM-2-10G module supports VLAN ACLs, which allow you to filter traffic based on source and destination IP addresses, MAC addresses, protocols, and other parameters. This feature helps to secure your network by preventing unauthorized access to the VLAN.
• Private VLANs: Private VLANs (PVLANs) allow you to divide a VLAN into sub-VLANs, which are isolated from each other. The C3850-NM-2-10G module supports PVLANs, which provide an additional layer of security by isolating devices from each other within the same VLAN. This feature is especially useful in large networks where multiple devices are connected to the same VLAN.
• Dynamic ARP Inspection: Dynamic ARP Inspection (DAI) is a security feature that prevents ARP spoofing attacks. The C3850-NM-2-10G module supports DAI, which validates ARP packets before forwarding them. This feature ensures that ARP packets are coming from a trusted source and that the source MAC address matches the IP address in the packet.
• Access Control Lists (ACLs): Access Control Lists (ACLs) allow you to control traffic entering or leaving a network interface. The C3850-NM-2-10G module supports ACLs, which allow you to filter traffic based on source and destination IP addresses, protocols, and other parameters. This feature helps to secure your network by preventing unauthorized access to your network.
• Identity-Based Networking: Identity-Based Networking (IBN) is a security feature that allows you to control access to your network based on the user's identity. The C3850-NM-2-10G module supports IBN, which allows you to set policies based on the user's identity, group membership, and other parameters. This feature helps to secure your network by ensuring that only authorized users have access to the network.
• Secure Shell (SSH): Secure Shell (SSH) is a protocol that provides secure remote access to network devices. The C3850-NM-2-10G module supports SSH, which allows you to securely access the switch remotely. This feature ensures that your remote access is secure and prevents unauthorized access to your network.
