The Cisco 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.

The course is available only as a private group training (up to 12 people).


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


The course contains these components:
  • Module 1: Getting Started with 4G Wi-Fi Offload:
    • Client versus clientless devices
    • Trusted versus untrusted devices
    • ePDG and Wi-Fi infrastructure
    • Role of wireless LAN controller (WLC)
    • SSIDs and VLANs
    • EAP-based WLAN authentication
    • Portal-based WLAN authentication
    • Obtaining IP address of ePDG
    • Attachment to mobile packet core via the ePDG
  • Module 2: Configuring the ASR 5000 as an ePDG:
    • SWu interface
    • IPsec transforms and policies
    • DIAMETER AAA SWm interface
    • PMIP interface to PGW
    • ePDG service configuration Role of DNS
    • Lab: Configuring an ePDG
  • Module 3: Monitoring and Troubleshooting ePDG Operation:
    • Viewing subscriber sessions
    • Obtaining IPSec information and statistics
    • Examining the ePDG service
    • DIAMETER proxy operation on the ASR 5000
    • Viewing MAG service operation
