Trace Logs
In addition to the syslog buffer, the Dell Networking OS buffers trace messages which are continuously
written by various software tasks to report hardware and software events and status information.
Each trace message provides the date, time, and name of the Dell Networking OS process. All messages are
stored in a ring buffer. You can save the messages to a file either manually or automatically after failover.
