You can specify the severity level for which log messages are to be generated for
each module. Logs are generated for events for which the severity level is equal to
or higher than the configured level. The following are the severity levels that you
can configure for each module:
 Emergency
 Alert
 Critical
 Error
 Warning
 Notice
 Information
By default, system-level logging is enabled. The system stores a maximum of 1000
log and trace messages. The system stores log and trace messages using the cyclic
buffer method. That is, when there are more than 1000 messages, the system
overwrites the oldest log and trace messages.
To configure logging, first specify system-level logging that is applicable across the
entire system. You can then configure logging, individually for each system
module. This section describes the commands to be used for:
 “Managing System-level Logging” on page 397
 “Configuring Module-level Logging” on page 406
IMPORTANT
The Syslog utility is used to implement the logging feature for 4Motion.
IMPORTANT
It is recommended that you periodically make backups of log messages before these are
overwritten. For details, refer to
“Making a Backup of Log Files on the NPU Flash” on
page 403
