1. Introduction

The Cisco

Next-Generation Enterprise WAN is an end-to-end architecture that provides foundation building blocks

for next-generation enterprise networks. The hierarchical design provides the scalability required by large

enterprises that can be extended and replicated throughout multiple regions and topologies. This consistency leads

to ease of deployment, maintenance, and troubleshooting.

This guide provides deployment, debugging, and troubleshooting information for the fourth-generation long-term

evolution (4G LTE) Cisco Enhanced High-Speed WAN Interface Cards (EHWICs), which provide wireless 4G

networking capability on the Cisco Integrated Services Routers Generation 2 (ISR G2) (Cisco 1900, 2900, and

3900 Series Integrated Services Routers). This guide is also applicable to fixed Cisco ISR platforms (Cisco 800

Series ISRs) with 4G LTE as a wireless WAN (WWAN) interface with minor changes pointed out in configurations.

This guide is intended for users of Cisco ISR G2 routers with 4G LTE as a WWAN interface, including system

integrators, network architects, and support engineers. This guide provides a brief overview of the cellular

networks, their architecture, and their relevance to the enterprise networks. It assumes basic knowledge of Cisco

IOS

Software command-line interface (CLI) configuration.

This guide discusses the cellular technology architecture and evolution. It explains how Cisco intends this

technology to be used in enterprise networks. Sections provide information about activation, basic configuration,

and troubleshooting of the WWAN interface on Cisco ISR G2 routers. This guide builds on that basic information to

cover the advanced deployments including VPNs, dynamic routing, and other advanced services that are enabled

by Cisco IOS Software.
