About the Cisco SM-ES2-24-P= Cisco Service Module
The Cisco SM-ES2-24-P= EtherSwitch Service Module expands network port density and switching intelligence directly within Cisco ISR G2 routers, eliminating the need for separate access layer switches and delivering 24 Fast Ethernet ports with integrated Layer 2 and Layer 3 switching capability. This service module is purpose-built for network engineers seeking to consolidate routing, security, and switched access functions within a single chassis, reducing operational complexity and physical footprint in branch and mid-market deployments.
The SM-ES2-24-P= provides 24 access ports operating at 10/100 Mbps with full IEEE 802.3af Power over Ethernet across all ports, backed by a 370W total PoE power budget for concurrent IP phone and wireless access point deployments. Two Gigabit Ethernet uplinks (10/100/1000 Mbps) connect to the ISR G2 backplane, while enterprise-class features including IEEE 802.1Q VLAN trunking (up to 255 VLANs), STP/RSTP/PVST+ redundancy, inter-VLAN routing, QoS with DSCP marking, and IEEE 802.1X authentication ensure carrier-grade reliability. Integrated Cisco IOS CLI and SNMP management simplify provisioning within the ISR G2 router management plane, and genuine Cisco hardware validation enables full TAC support eligibility.
Enterprise Deployment Scenarios
- Branch office consolidation: Collapse router and access switch into one ISR G2 chassis, reducing rack space and operational overhead at remote sites
- IP phone and wireless access point aggregation: Leverage 370W PoE budget to power multiple unified communications and mobility endpoints from a single module
- VLAN segmentation and inter-VLAN routing: Deploy up to 255 VLANs with static routing and Layer 3 switching for multi-tenant or departmental network isolation
- Port-based access control: Enforce IEEE 802.1X authentication and DHCP snooping at the access layer to strengthen network perimeter security
- Redundancy and failover: Enable STP and RSTP to prevent bridging loops and maintain high availability in converged routing and switching environments
