The Cisco SM-X Layer 2/3 EtherSwitch Service Modules (Cisco SM-X Layer 2/3 ESM) integrates the
Layer 2 and Layer 3 switching features and provide the Cisco 2900 series and Cisco 3900 series ISRs
the ability to use the Cisco SM-X Layer 2/3 ESM as an independent Layer 3 switch when running the
Cisco IOS software.

The Cisco SM-X Layer 2/3 ESMs also provide a 1-Gbps connection to the multigigabit fabric (MGF)
for intermodule communication without burdening your router’s CPU.

The Cisco SM-X Layer 2/3 ESMs are capable of providing up to 30 watts of power per port with the
robust Power over Ethernet Plus (PoE+) feature along with IEEE 802.3ae Media Access Control Security
(MACSec) port-based, hop-to-hop, encryption, and Cisco TrustSec (CTS) that work on multiple router
families

The Cisco SM-X Layer 2/3 ESM can co-exist with EtherSwitch service modules from previous releases
on the host Cisco 2900 and 3900 series ISRs and these modules are capable of interoperability with each
other. Support for the maximum number of service modules that can be present on the 2900 and 3900
series ISRs is dictated by the total number of service module slot count on the host router.
