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.

Download Information

Since these modules are inserted into Cisco Integrated Services Routers, the software is downloaded from the same folder as the Cisco 2911, 2921, 2951, 3925, or 3945 routers. The following pointer is linked to the Cisco 2951 Integrated Services Router. The Enhanced EtherSwitch software is the same regardless of what router's folder it is posted in.
