It provides four Gigabit Ethernet ports that can be used to connect devices such as computers, servers, and other networking equipment to the network. Some key features and performance characteristics of the C3KX-NM-1G= include:

• Data transfer rates: The ports on the Part support speeds of up to 1 Gbps.
• Network connectivity: The module has four Gigabit Ethernet ports, which can be used to connect a variety of devices to the network. The ports can be configured as either copper or fiber optic, depending on the needs of your network.
• Compatibility: The Part is compatible with Cisco Catalyst switches, and it can be used to add additional ports to these switches.

Features and Benefits

The C3KX-NM-1G Cisco 4 Ports Gigabit Ethernet Network Module is an expansion module that can be installed in a Cisco Catalyst 3750-X or 3560-X switch to increase its network connectivity capabilities. Here are some of the key features and benefits of this module:

Features:

• Four Gigabit Ethernet ports: The module provides four high-speed Gigabit Ethernet ports, each with a data transfer rate of up to 1 Gbps.
• Hot-swappable: The module is hot-swappable, which means it can be installed or removed from the switch without shutting down the system or disrupting network connectivity.
• Compatibility: The module is compatible with both copper and fiber-optic cabling.
• Auto-negotiation: The module supports auto-negotiation, which means it can automatically detect the speed and duplex mode of connected devices.
• Jumbo frames support: The module supports jumbo frames up to 9216 bytes.

Benefits:

• Increased network connectivity: With four additional Gigabit Ethernet ports, the module expands the network connectivity capabilities of the switch.
• Flexibility: The module is compatible with both copper and fiber-optic cabling, providing flexibility in network design and allowing for longer distance connections.
• Hot-swappable: The hot-swappable feature of the module makes it easy to install or remove the module without causing network downtime.
• Auto-negotiation: The auto-negotiation feature allows the module to automatically detect the speed and duplex mode of connected devices, simplifying network configuration and reducing errors.
• Jumbo frames support: The jumbo frames support feature allows for larger packet sizes, which can improve network performance in certain applications such as video streaming or large file transfers.

Network Management and Security

The C3KX-NM-1G Cisco 4 Ports Gigabit Ethernet Network Module can be managed and secured through a variety of methods. Here are some network management and security considerations for this module:

• Network Management: The module can be managed through various network management protocols, such as Simple Network Management Protocol (SNMP), Command Line Interface (CLI), and Simple Network Management Protocol version 3 (SNMPv3). These protocols allow administrators to monitor the status of the module, configure settings, and diagnose any issues that may arise.
• Access Control: Access control mechanisms should be implemented to ensure that only authorized personnel can manage the network module. This can be achieved by using features such as Access Control Lists (ACLs) and authentication protocols such as RADIUS and TACACS+.
• Firmware updates: Regular firmware updates should be performed to keep the module up-to-date with the latest security patches and bug fixes. These updates can be done through various methods, including CLI, SNMP, or using Cisco's firmware management tools.
• Port Security: The module supports port security features such as MAC address limiting, which limits the number of MAC addresses that can be learned on a port. This helps prevent unauthorized devices from connecting to the network.
• VLANs: Virtual Local Area Networks (VLANs) can be implemented to segment the network and improve security. This can be achieved by assigning each port on the module to a different VLAN, which can prevent unauthorized access to sensitive network resources.
• Network Monitoring: Network monitoring tools can be used to detect any suspicious activity on the network, such as unauthorized access attempts or abnormal traffic patterns. This can help administrators detect and respond to security threats in a timely manner.
