Detailed Information
Enhanced EtherSwitch Service Modules for Integrated Services Routers Generation 2
The Cisco Enhanced EtherSwitch Service Modules greatly expand the router’s capabilities by integrating industry-
leading Layer 2 and Layer 3 switching with feature sets identical to those found in the Cisco Catalyst 3560-E and
Cisco Catalyst 2960 Series Switches. The new Cisco Enhanced EtherSwitch Service Modules are the first modules
to take advantage of the increased capabilities on the Cisco 3900 and 2900 Series Integrated Services Routers.
Additionally, these service modules enable Cisco’s industry-leading power initiatives, Cisco EnergyWise, Cisco
Enhanced Power over Ethernet (ePoE), and per-port PoE power monitoring—all of which enhance the ability of the
branch office to scale to next-generation requirements and still meet important initiatives for IT teams to operate a
power-efficient network. Furthermore, the Cisco Enhanced EtherSwitch Service Modules not only perform local line-
rate switching and routing but also support direct service module-to-service module communication through the
Integrated Services Router Generation 2 multigigabit fabric (MGF), which separates LAN traffic from WAN
resources.
