Two types of Cisco Enhanced EtherSwitch Service Modules are available (Table 1): Entry Level (ES2) and Advanced

(ES3).

Table 1. Entry-Level and Advanced Cisco Enhanced EtherSwitch Service Modules

Cisco Enhanced EtherSwitch

Service Module

Description

Cisco ES3 Enhanced EtherSwitch

Service Module

Best-of-class Ethernet switching

High-density Gigabit Ethernet support

Layer 2/3 switching in hardware

Multicast routing

IPv6 routing, and access control list (ACL) in hardware

Full feature parity with the Cisco Catalyst 3560-E IP Base and IP Services Universal images

IP Base feature set, which includes advanced quality of service (QoS), a suite of security features, rate

limiting, ACLs, basic static and Routing Information Protocol (RIP) routing capability, and Hot Standby

Router Protocol (HSRP)

The IP Services feature set provides a richer set of enterprise-class features, including advanced

hardware-based IP Unicast and IP Multicast routing; Enhanced Interior Gateway Routing Protocol

(EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent

Multicast (PIM), and IPv6 routing; OSPFv3; EIGRPv6; IP Service-Level Agreement (IPSLA) packet

monitoring; Cisco Port Security; and Virtual Route Forwarding Lite (VRF Lite)

Cisco EnergyWise technology, an innovative architecture that promotes companywide sustainability by

reducing energy consumption across an entire corporate infrastructure; Cisco EnergyWise technology

can help your company measure the power consumption of network infrastructure and network-attached

devices and manage power consumption with specific policies, reducing power consumption to realize

increased cost savings; potentially any powered device is affected

Power over Ethernet; up to 1014 watts per chassis on a Cisco 3900 Series router

Cisco Enhanced PoE (ePoE), up to 20 watts per port

IEEE 802.3af PoE support, up to 15.4 watts per port

Cisco pre-standard PoE

Cisco ES2 Enhanced EtherSwitch

Service Module

Entry-level, lower-cost solution

Layer 2 switching in hardware

Full feature parity with the Cisco Catalyst 2960 LAN Base image

Power over Ethernet; up to 1014 watts per chassis on Cisco 3900 Series router

IEEE 802.3af PoE support, up to 15.4 watts per port

Cisco pre-standard PoE

Secure Network Connectivity for Data, Voice, and Video

When inserted within a Cisco 2900 or 3900 Series Integrated Services Router, such as the Cisco 3945 (Figure 2),

the Cisco Enhanced EtherSwitch Service Modules provide a fully integrated, secure networking and converged IP

communications solution. From a single platform with an integrated switch, you can connect IP phones, wireless

access points, and IP-based video cameras to your network and power them using the IEEE 802.3af, Cisco ePoE, or

Cisco pre-standard PoE. With the optional integration of Cisco Unified Communications Manager Express, the router

can also provide call-processing for the phones. As users attempt network access through the Cisco Enhanced

EtherSwitch Service Module, the module can use IEEE 802.1x and a large number of Cisco 802.1x extensions to

validate the credentials of the end device and place the user in the appropriate VLAN or Cisco TrustSec group. As

the end-user data leaves the LAN, the router can encrypt the traffic and place it on a multitude of VPNs, securing

communications between branch offices and central sites.

This high degree of convergence simplifies the network architecture and allows for cost-effective deployment of

advanced services at the branch-office level. Furthermore, because the Cisco Enhanced EtherSwitch Service

Modules support the same feature sets as the Cisco Catalyst 2960 and Catalyst 3560-E Switches, you can provide a

ubiquitous configuration at headquarters and at the branch office to create a consistent experience throughout your

network.
