Introduction
This document describes how to configure the Failure−Handling (FH) and Server−Unreachable (SU)
mechanisms on the Gy interface in order to resolve issues that are encountered on the Online Charging
System (OCS) or in regards to connectivity between the Policy and Charging Enforcement Function (PCEF)
and the OCS. The information that is described in this document is applicable to the Home Agent (HA),
Gateway General Packet Radio Service (GPRS) Support Node (GGSN), and Packet Data Network Gateway
(PGW) functionalities that run on the Cisco 5000 Series Aggregated Services Router (ASR5K).
