Cisco 4- and 8-Port Gigabit Ethernet Enhanced High-Speed WAN

Interface Cards

Product Overview

The 4- and 8-port Cisco

Gigabit Ethernet Enhanced High-Speed WAN interface cards (EHWICs) can reduce your

company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) switch ports within Cisco 3900, 2900,

and 1900 Series Integrated Services Routers (ISRs). These low-density Gigabit Ethernet switches offer small to

medium-sized business (SMB) and enterprise branch-office customers a combination of switching and routing

integrated into a single device (Figure 1).

Integration of these switches with Cisco IOS

Software allows network administrators to manage a single device

using Cisco management tools or the router command-line interface (CLI) for LAN and WAN management needs.

This approach reduces network complexity, lowers maintenance contract costs, and lessens staff training needs. It

also simplifies software qualification efforts and delivers a consistent user experience at branch offices. Additionally,

these low-density Gigabit Ethernet switching modules enable Cisco's industry-leading power initiatives, Cisco

EnergyWise, Cisco Enhanced Power over Ethernet (ePoE), and per-port Power over Ethernet (PoE) power

monitoring, which enhance the ability of the branch office to scale to higher performance requirements and still meet

environmental initiatives for IT teams to operate a power-efficient network.

The 4- and 8-port Gigabit Ethernet EHWICs provide line-rate Layer 2 switching across onboard Gigabit Ethernet

ports. The 4-port Gigabit Ethernet EHWIC has four 10/100/1000 switch ports, with options for PoE support on all four

ports. The 8-port Gigabit Ethernet EHWIC has eight 10/100/1000 switched Gigabit Ethernet ports, with a PoE

support option on all 8 ports.

The new features for the Gigabit Ethernet EHWICs include: 8 quality-of-service (QoS) queues per port, Shaped

Deficit Weighted Round Robin (SDWRR), dynamic secure port, intrachassis cascading, up to 20W of PoE per port,

and PoE per-port monitoring and policing. Multigigabit Fabric (MGF) is enabled for direct module-to-module

communication.

Secure Network Connectivity for Data, Voice, and Video

When inserted in a Cisco 1900, 2900, or 3900 Series ISR, the Gigabit Ethernet EHWICs 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 or Cisco ePoE. 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, the Gigabit Ethernet

EHWIC can use IEEE 802.1x to validate the credentials of the end device and place the users in the appropriate

VLAN or Cisco TrustSec

™

group. As the end-user data leaves the LAN, the router can then encrypt the traffic and

place it on a multitude of VPNs, securing the communications among branch offices and central sites.

Data Sheet Features and Benefits The Cisco Gigabit Ethernet EHWICs provide increased performance levels, enhanced per-port security, ease of configuration, and, with intermodule cascading capabilities, they allow for additional ports expandability over time. Table 1 lists some important business benefits of deploying an integrated switching solution. Table 1.

Data Sheet Additional PoE features include: ● Per-port power consumption control allows you to specify a maximum power setting on an individual port. ● Per-port PoE power sensing measures the actual power being drawn, enabling more intelligent control of powered devices. ● The Cisco PoE MIBs provide proactive visibility into power usage and allow you to set different power-level thresholds.

Data Sheet Figure 3. Typical Data, Voice, Video, and Wireless Access Points Converged Deployment for a SMB When deployed in a unified communications environment, the 4- or 8-port Cisco Gigabit Ethernet EHWICs transparently interoperate with analog or digital time-division multiplexing (TDM) voice gateway modules and Cisco Unified Communications Manager Express IP Telephony, Cisco Survivable Remote Site Telephony (SRST), or Cisco Unified Border Element solutions.

Data Sheet Feature Benefit Intrachassis stacking or cascading ● Grouping EHWIC switch modules together is called cascading. The EHWIC switch modules are capable of cascading on all Cisco Integrated Services Routers Generation 2 (ISR G2) platforms using the internal MGF. ● Cascading of multiple EHWIC switches over the MGF allows multiple EHWICs to behave as a single switch.
