Cisco 4-Port Fast Ethernet Switch WAN Interface Card
for Cisco

1700

Series Modular Routers

The Cisco 4-port 10/100BASE-T Fast Ethernet Switch WAN Interface Card

(WIC-4ESW) for Cisco 1700 Series modular access routers is an intelligent managed

switch, offering small businesses and enterprise small branch office customers the

option to integrate LAN switching and routing into one platform. The advanced

capabilities of the WAN interface card (WIC), including VLAN support, Spanning Tree

Protocol, and traffic prioritization, provide the flexibility for customers to deploy

different network configurations.

Introduction

The Cisco 4-Port Fast Ethernet Switch

WIC (Figure 1) extends the capabilities of

Cisco 1700 Series modular access routers,

providing four additional Fast Ethernet

ports for expanded network deployments.

When installed in the WIC or WIC/VIC slot

of the router, this 4-port 10/100BASE-T

switch WIC enables delivery of LAN

services for connecting PCs, printers, server

farms, wireless access points, or other LAN

devices. The 10/100BASE-T Fast Ethernet

port onboard the Cisco 1700 Series router

can be connected to an external DSL or

cable modem to provide high-speed

broadband services.

Managed Fast Ethernet Switch

Features

The Cisco 4-Port Fast Ethernet Switch

WIC is an intelligent Ethernet switch

that provides several autodetect features,

such as half- or full-duplex autosensing,

10/100BASE-T autosensing, and automatic

crossover detection. These features reduce

first-time configuration steps and allow for

flexibility when your network architecture

changes.

Because it is also a managed switch, the

Cisco 4-Port Fast Ethernet Switch WIC

offers more capabilities and business

advantages than most integrated switching

solutions available for routers and security

appliances. Support for standards-based

IEEE features such as 802.1Q VLAN,

802.1p traffic prioritization, and 802.1D

Spanning Tree Protocol makes the WIC a

powerful component for Cisco 1700 Series

modular access routers.

802.1Q VLAN technology allows devices

such as hosts, servers, and printers that are

connected to separate physical LANs to be

grouped logically as though they were part

of the same LAN. This provides ease of

management and offers flexibility in

deploying an optimized network solution.
