network and interface card modules are innovative solutions that can reduce
total cost of ownership for customers by optionally integrating switch ports within a router. This
integration allows network administrators to manage a single device utilizing the router command-
line interface (CLI) for LAN and WAN management needs. This approach reduces network
complexity, IT staff training needs, equipment sparing requirements, and maintenance costs.
Product Overview
The new Cisco EtherSwitch service modules, pictured in Figure 1, greatly expand the capabilities
of integrated switching within Cisco routers by providing support for new features such as IEEE
802.3af Power over Ethernet (PoE), local Layer 3 switching, Cisco Network Assistant and Cisco
Emergency Responder, and Cisco StackWise
™
interfaces (available on NME-XD-24-1S-P only),
as well as common software and features with Cisco Catalyst
®
3750 and 3750-E Series Switches.
Additionally, the new Cisco EtherSwitch service modules are the first modules that can take full
advantage of the increased performance capabilities and new form factors of the enhanced
network module slot on Cisco integrated services routers. (Table 7 provides a list of supported
platforms).

Secure Network Connectivity for Data, Voice, and Video
When combined with a Cisco integrated services router, such as the Cisco 2821 pictured in
Figure 2, the new Cisco EtherSwitch service modules can provide a fully integrated secure
networking and converged IP Communications solution. From a single platform, IP phones can be
connected to the network and powered using the IEEE 802.3af standard or pre-standard Cisco
Power over Ethernet (PoE). With the optional addition of Cisco Communications Manager Express
(formerly CallManager Express), the router can also provide the call processing for these phones.
Further, as users attempt network access through the Cisco EtherSwitch service module, the
module can use 802.1x to validate the end device's credentials and place the user in the
appropriate VLAN. As the end-user data leaves the LAN, the router can encrypt the traffic, helping
to ensure secure communications between branch offices and central sites. This high degree of
convergence greatly simplifies network architecture and allows for advanced services to be
deployed to the branch level in a cost-effective manner.
