Course Details

ASR 5000 TTG System Administration (TTG)

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).

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 eWAG
  • Monitoring the system for proper subscriber session establishment
  • Basic debugging of initial attachment failure

At the completion of this course, all participants receive a certificate of completion.
