Receiving system log messages

You can use the system log messaging feature of the Passport 8000 Series to manage switch event messages on any UNIX-based management platform. The Passport 8000 Series syslog software supports this functionality by communicating with a counterpart software component named syslog on your management workstation. The UNIX daemon syslogd is a software component that receives and locally logs, displays, prints, and/or 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 running on the workstation, as well as messages received from Passport 8000 Seriess running in a network accessible to the workstation.

At a remote UNIX management workstation, the system log messaging feature does the following:

• Receives system log messages from the Passport 8000 Series
• Examines the severity code in each message
• Uses the severity code to determine appropriate system handling for each message
• Based on the severity code in each message, dispatches each message to any or all of the following destinations:

­	Workstation display

­	Local log file

­	Designated printer

­	One or more remote hosts

Internally the Passport 8000 Series has four severity levels for log messages:

• Info
• Warning
• Error
• Fatal

The system log feature supports eight different severity levels:

• Debug
• Info
• Notice
• Warning
• Error
• Critical
• Alert
• Emergency

• Default severity levels and system log severity levels table
