Troubleshooting CGF Dead Alarms and Traffic Issues in Telecommunications Networks For VIL

Overview

The customer is experiencing an issue with their Gateway (GW) team continuously receiving CGF dead alarms. They are also receiving traffic on both active and passive collector nodes, which is not in line with the standard logic of CGF Design. The issue seems to be related to the CGF (Charging Gateway Function) system, which is part of a telecommunications network and is responsible for collecting charging data from various network nodes and forwarding it to the appropriate charging systems.

Recording: Explaining the issue

Ticket: 4100248

Solution

The issue was due to a significant increase in latency and a large number of packet drops between the CGF collector and the G/W end. The solution involved the following steps:

1. The customer was asked to check with the IP team regarding the observed latency and packet drops.
2. 
3. The customer was also asked to provide the CGF dead alarm dump for the dates when the issue started.
4. The customer was advised to open a new problem ticket if the issue was not resolved after IP TAC analysis.

The issue was resolved after the customer confirmed that they had instructed INM to open a new problem ticket if the issue was not resolved after IP TAC analysis.

Summary

CGF dead alarms and traffic issues in telecommunications networks can be caused by a significant increase in latency and a large number of packet drops between the CGF collector and the G/W end. These issues can be resolved by checking for latency and packet drops, providing the CGF dead alarm dump, and if necessary, involving the IP team for further analysis and resolution.
