Product Overview of the Cisco C3KX-NM-1G 4 Ports Network Module

The Cisco C3KX-NM-1G is a network module that can be installed in Cisco Catalyst 3750-X and 3560-X Series Switches. These switches are widely used in enterprise networks, data centers, and other networking environments due to their reliability, performance, and scalability. The C3KX-NM-1G module adds 4 Gigabit Ethernet ports to the switch, which can be used for various networking tasks such as connecting devices, creating VLANs, and expanding network capacity.

Hot-Swappable

The Cisco C3KX-NM-1G is hot-swappable, meaning it can be inserted or removed without powering down the connected switch. This feature is essential for minimizing network downtime during installation or maintenance. With hot-swappability, network administrators can add or replace modules while the switch is still operational, reducing disruptions and ensuring network continuity.

Gigabit Ethernet Support

The most prominent feature of this network module is its support for Gigabit Ethernet. Each of the 4 ports is capable of handling 1 Gbps data transfer speeds, which is essential for high-speed data transmission in today's networks. Gigabit Ethernet is a standard for modern networks, enabling the efficient transfer of large data files and ensuring a seamless user experience.

Compatibility with SFP Modules

This network module is compatible with Small Form-Factor Pluggable (SFP) modules. SFP modules are interchangeable and can be easily swapped out to adapt to various networking needs. The Cisco C3KX-NM-1G's compatibility with SFP modules allows organizations to choose the appropriate transceivers and cables based on their specific requirements, whether it's fiber optics or copper connections.

LED Indicators

The Cisco C3KX-NM-1G features LED indicators for each of its ports. These indicators provide essential information about the status of the ports, such as link activity and speed. This visual feedback simplifies network troubleshooting and helps administrators quickly identify any issues with individual connections.

Energy-Efficient Design

In line with Cisco's commitment to sustainability and energy efficiency, the C3KX-NM-1G is designed to optimize power consumption. It is compliant with energy-efficient Ethernet standards, ensuring that it consumes power efficiently while maintaining network performance. This not only reduces operational costs but also contributes to environmental sustainability.

Increased Network Capacity

One of the primary advantages of the Cisco C3KX-NM-1G is the increased network capacity it provides. With four additional Gigabit Ethernet ports, organizations can connect more devices to the network without experiencing congestion or slowdowns in data transfer. This is especially valuable for businesses with expanding network requirements.

Flexibility in Network Design

The module's compatibility with SFP modules adds a layer of flexibility to network design. Organizations can choose the type of transceivers and cables that best suit their network topology, whether it's for short-range connections within a data center or long-distance connections between buildings.

By ensuring compatibility with these two popular series of switches, Cisco provides its customers with a versatile and cost-effective solution to enhance their network infrastructure.

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.
