Enhancing Network Security

The C3850-NM-2-10G is an expansion module designed to enhance the network security of Cisco Catalyst 3850-24 switches. This module provides two additional 10 Gigabit Ethernet (10GbE) ports to the switch, which can be used for high-speed connectivity to servers, storage devices, or other network switches.

Here are some of the key features and benefits of the C3850-NM-2-10G:

• High-speed connectivity: The module provides two 10GbE ports, which can deliver high-speed connectivity for demanding applications such as video streaming, data backup, and virtualization.
• Increased bandwidth: By adding two 10GbE ports to the switch, the module increases the overall bandwidth of the network, which can help to improve performance and reduce latency.
• Network security: The C3850-NM-2-10G module supports several security features that can help to protect the network from unauthorized access, data breaches, and other security threats. For example, it supports IEEE 802.1X port-based authentication, which can prevent unauthorized devices from accessing the network.
• Simplified management: The module can be managed using Cisco's Prime Infrastructure management software, which provides a centralized interface for configuring and monitoring network devices.
• Easy installation: The module is designed for easy installation and can be installed without disrupting the operation of the switch.

Cost Analysis of Implementing with Expansion Module

The Cisco C3850-NM-2-10G expansion module is an add-on module for the Catalyst 3850-24 switch that provides two additional 10 Gigabit Ethernet (GbE) ports. The cost analysis of implementing this module involves considering the upfront cost of purchasing the module, as well as ongoing operational costs.

Upfront Costs: The Cisco C3850-NM-2-10G expansion module has a list price of around $2,000, but actual prices may vary depending on the vendor, purchase volume, and other factors. The upfront cost also includes the cost of installation, configuration, and any necessary cabling and power infrastructure upgrades.

Operational Costs: The operational costs associated with the Cisco C3850-NM-2-10G expansion module depend on the specific deployment scenario and network requirements. These costs can include:

• Power Consumption: The module will consume additional power, which may increase energy costs.
• Maintenance and Support: The module may require maintenance or replacement if it fails, which could lead to additional costs for parts and labor.
• Training: If your IT staff is not already familiar with configuring and managing the Cisco Catalyst 3850 switch with the expansion module, they may need to undergo training or certification, which can incur additional costs.
• Software Licensing: Depending on the specific features and capabilities required, additional software licensing may be needed for the switch and the expansion module.
• Operational Efficiency: The expansion module may improve network performance and efficiency, which can lead to cost savings in other areas of the organization.

Security Features of 2 Ports Module

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.
