Description
The Cisco SM-ES2-24 is a 24-port Enhanced EtherSwitch service module designed for Cisco Integrated Services Routers (ISR). This module provides integrated Layer 2 switching capabilities directly within the router chassis, enabling organizations to combine routing and switching functions in a single platform. The SM-ES2-24 includes 23 Fast Ethernet (10/100 Mbps) ports and one Gigabit Ethernet uplink port, allowing multiple network devices to connect efficiently within branch office or enterprise edge environments.The module integrates seamlessly with compatible Cisco ISR routers and operates under Cisco IOS software, providing a comprehensive set of Layer 2 switching features such as VLAN segmentation, port security, Quality of Service (QoS), and traffic management. By integrating switching capabilities directly into the router, the SM-ES2-24 helps reduce network complexity and eliminates the need for additional standalone switches in smaller deployments.
This EtherSwitch module is well suited for branch offices, remote sites, and enterprise networks that require reliable LAN connectivity for devices such as workstations, IP phones, wireless access points, and other network equipment. Its modular design allows easy installation into supported router service module slots, providing a scalable and cost-effective solution for expanding Ethernet connectivity while maintaining centralized network management and high operational reliability.
