Cisco SM-ES2-24-P Enhanced EtherSwitch Service Module

The Cisco SM-ES2-24-P Enhanced EtherSwitch Service Module is a purpose-built solution designed to streamline your network by bringing robust Ethernet switching directly into Cisco 3900 and 2900 Series Integrated Services Routers. By embedding Gigabit Ethernet (GE) and Fast Ethernet (FE) switch ports into your ISR, this module enables IT teams to manage both routing and switching from a single, familiar Cisco IOS environment. The result is a more compact and efficient network architecture, lower total cost of ownership, and simplified deployment that accelerates time-to-value for campuses, branch offices, and data centers alike.

• Unified platform for routing and switching: The SM-ES2-24-P delivers high-performance Ethernet switching directly within your ISR, enabling centralized control, simplified topology, and reduced cable clutter. This integration minimizes the need for separate switching gear in edge locations and ensures consistent policy enforcement across both routing and switching paths.
• 24 Ethernet ports with scalable performance: This service module provides 24 GE/FE switch ports, delivering dense access-layer connectivity while preserving low latency and predictable performance. The dense port count supports large VLAN deployments, efficient device handoffs, and flexible workgroup configurations without compromising reliability.
• Advanced edge features for secure, policy-driven networks: Leverage Layer 2 switching capabilities, VLAN segmentation, QoS prioritization, and security controls directly on the router. These features help guarantee critical applications—such as voice, video, and real-time collaboration—receive the bandwidth and priority they require while maintaining strong access control lists and monitoring capabilities.
• Seamless integration with Cisco IOS and ISR family: Designed to work within the Cisco IOS ecosystem, the SM-ES2-24-P adheres to familiar management workflows. Administrators can configure, monitor, and troubleshoot the module via standard IOS commands and existing Cisco management tooling, reducing training time and accelerating rollout.
• Cost-efficient deployment and simplified administration: By consolidating switching and routing into a single device, organizations reduce hardware footprint, cabling complexity, energy consumption, and operational overhead. The result is a leaner network that is easier to manage and scale as business needs evolve.

How to Install Cisco SM-ES2-24-P

• Power down the router and prepare a safe installation workspace; access the router’s service-module slot intended for the Enhanced EtherSwitch module.
• Insert the SM-ES2-24-P firmly into the appropriate ISA slot or dedicated service-module bay, ensuring proper alignment and secure latching to prevent disconnects during operation.
• Reconnect power and boot the router; verify the module is recognized by the system through the IOS, observing any system messages or indicators indicating successful initialization.
• Configure the module using Cisco IOS commands to define VLANs, assign switch ports, and establish trunking or access port modes. Apply QoS policies, security settings, and any required ACLs to protect network traffic as it traverses the integrated switching fabric.
• Validate end-to-end operation by testing connectivity between devices, verifying VLAN segmentation, and monitoring switch health with IOS diagnostics and your preferred management tools. Make adjustments as needed to optimize performance and reliability.
