    Course Details

    Overview

    This course provides detailed instruction on how to configure and monitor the Cisco® ASR 5000 to function as a tunnel termination gateway (TTG) in a 3G Wi-Fi offload network environment. The TTG provides interworking between a wireless LAN (WLAN) and a 3G mobile packet core (MPC).

    Objectives

    Upon completion of this course, you should have a thorough understanding of the following aspects of the platform:

    • Performing basic service configuration and monitoring of the TTG.
    • Monitoring the system for proper subscriber session establishment.
    • Basic debugging of initial attachment failure.
