Cisco ISR 4000 Configuration Guide

By PivIT Global

Introduction

The 4000 Series ISRs are Cisco’s versatile modular routers with LAN and WAN connections that can be configured by means of interface modules, including Cisco Enhanced Service Modules (SM-Xs), and Network Interface Modules (NIMs). NIM slots also support removable storage for hosted applications.

The following features are provided for enterprise and service provider applications:

  • Enterprise Applications
    • High-end branch gateway
    • Regional site aggregation
    • Key server or PfR master controller
    • Device consolidation or "Rack in a Box"
  • Service Provider Applications
    • High-end managed services in Customer-Premises Equipment (CPE)
    • Services consolidation platform
    • Route reflector or shadow router
    • Flexible customer edge router

The router runs Cisco IOS XE software and uses software components in many separate processes. This modular architecture increases network resiliency, compared to standard Cisco IOS software.

Cisco Smart Licensing - An Overview

Based on a single technology, Smart Licensing has been designed to provide enterprise-level agreements for all Cisco products. Smart Licensing provides a software inventory management system that provides customers, Cisco, and selected partners with information about software ownership and software utilization.

Smart Licensing is a software based end-to-end license platform that comprises several tools and processes that authorizes customers to use and to report Cisco products. Smart licensing has the capability to capture a customer's order and to communicate with Cisco Cloud License Service through the Smart Call Home Transport Gateway. Additionally, the Smart Call Home Transport Gateway helps to complete product registration and authorization based on the desired performance and technology levels of Cisco products.

Smart Licensing State Descriptions
