Features and Benefits

The Cisco SM-X-6X1G is a 6-port SFP Gigabit Ethernet service module designed to provide high-performance connectivity for Cisco Integrated Services Routers (ISR) and Cisco 4451-X routers. This expansion module offers several features and benefits, including:


  • High-speed connectivity: The module provides six SFP (Small Form-Factor Pluggable) ports, each capable of supporting up to 1 Gbps of data transfer rate.
  • Flexible deployment options: The module is designed to work with a variety of SFP transceivers, allowing for flexibility in network deployment.
  • Hot-swappable: The module supports hot-swappable insertion and removal, allowing for easy replacement or upgrade without affecting the router's operation.
  • VLAN support: The module supports VLAN tagging, allowing for better traffic management and network segmentation.
  • Quality of Service (QoS) support: The module supports QoS, enabling prioritization of traffic and improving network performance for critical applications.


  • Improved network performance: The high-speed connectivity of the module allows for faster data transfer, reducing network latency and improving overall performance.
  • Scalability: The module's flexibility allows for easy expansion of the network, making it a cost-effective solution for businesses that need to scale their operations.
  • Reduced downtime: The module's hot-swappable feature allows for quick and easy replacement, reducing network downtime and increasing uptime.
  • Better traffic management: The module's VLAN support and QoS capabilities allow for better traffic management and network segmentation, resulting in improved network efficiency.
  • Enhanced security: The module supports secure networking protocols, such as MACSec (Media Access Control Security), providing enhanced network security.
Configuring and Managing

The Cisco SM-X-6X1G is an expansion module that adds six Gigabit Ethernet ports to compatible Cisco Integrated Services Routers (ISRs). Here are the steps to configure and manage this service module:

  • Install the module: Physically install the SM-X-6X1G module into the slot on the ISR. Ensure that the module is securely fastened in the slot.
  • Connect cables: Connect the SFP transceivers and fiber optic cables to the module's Gigabit Ethernet ports. Ensure that the cables are properly connected and secured.
  • Configure the module: Configure the module using the command-line interface (CLI) or web-based interface (GUI) of the ISR. You can configure basic settings such as port speed and duplex, VLANs, and security features. You can also configure advanced features such as Quality of Service (QoS) and Link Aggregation Control Protocol (LACP).
  • Monitor the module: Monitor the module's performance and status using the CLI or GUI of the ISR. You can view information such as port statistics, interface errors, and CPU utilization. You can also configure alerts and notifications for specific events.
  • Troubleshoot the module: Troubleshoot any issues with the module using the CLI or GUI of the ISR. You can use diagnostic tools such as ping and trace route to test connectivity. You can also use debug commands to identify and resolve issues with the module's configuration or performance.
Performance and Reliability

The Cisco SM-X-6X1G is a high-performance service module that provides six Gigabit Ethernet ports for compatible Cisco Integrated Services Routers (ISRs). Here are some key factors that contribute to the performance and reliability of this module:

  • High bandwidth: The SM-X-6X1G module supports up to six Gigabit Ethernet ports, providing high-speed connectivity for network devices. With a maximum data transfer rate of 1 Gbps per port, the module can handle large amounts of network traffic.
  • Low latency: The module is designed to minimize latency, ensuring that data packets are delivered quickly and efficiently. This is particularly important for real-time applications such as video conferencing and online gaming.
  • Quality of Service (QoS): The module supports QoS features, allowing you to prioritize network traffic and ensure that critical applications receive the necessary bandwidth. QoS can help prevent network congestion and improve overall performance.
  • Redundancy: The SM-X-6X1G module supports link redundancy through protocols such as Virtual Router Redundancy Protocol (VRRP) and Hot Standby Router Protocol (HSRP). These protocols allow for automatic failover in the event of a link or router failure, ensuring continuous network connectivity.
  • Security: The module supports a range of security features such as Access Control Lists (ACLs), port security, and 802.1X authentication. These features help to prevent unauthorized access to the network and protect against potential security threats.
