Description

The ASR 5000 ePDG System Configuration (ePDG1D) is a 1-day instructor-led course that introduces the learners to detailed instructions on how to configure and monitor the Cisco ASR 5000 to function as an evolved packet data gateway (ePDG) in a 4G Wi-Fi offload network environment.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:
  • Performing basic service configuration and monitoring of the ePDG
  • Monitoring the system for proper subscriber session establishment
  • Basic debugging of initial attachment failure
