Troubleshooting Guide

Chapter 8: Log and trap fundamentals
Use the information in this section to help you understand Simple Network Management Protocol
(SNMP) traps and log files, available as part of Avaya Virtual Services Platform 4000 Series System
Messaging Platform.
Overview of traps and logs
System log messaging
On a UNIX-based management platform, you can use system log (syslog) messaging to manage
event messages. The switch syslog software communicates with a server software component
named syslogd on the management workstation.
The UNIX daemon syslogd is a software component that receives and locally logs, displays, prints,
and forwards messages that originate from sources internal and external to the workstation. For
example, syslogd on a UNIX workstation concurrently handles messages received from applications
that run on the workstation, as well as messages received from the switch that run in a network
accessible to the workstation.
The remote UNIX management workstation performs the following actions:
• Receives system log messages from the switch .
• Examines the severity code in each message.
• Uses the severity code to determine appropriate system handling for each message.
Log consolidation
Virtual Services Platform generates a system log file and can forward that file to a syslog server for
remote viewing, storage and analyzing.
The system log captures messages for the following components:
• Extensible Authentication Protocol (EAP)
• Remote Authentication Dial-in User Service (RADIUS)
• Remote Monitoring (RMON)
• Web
• hardware (HW)
• MultiLink Trunking (MLT)
• filter
