EHWIC-D-8ESG 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.
