Information About System Message Logging
You can use system message logging to control the destination and to filter the severity level of messages that
system processes generate. You can configure logging to terminal sessions, a log file, and syslog servers on
remote systems.
System message logging is based on RFC 3164. For more information about the system message format and
the messages that the device generates, see the Cisco NX-OS System Messages Reference.
By default, the Cisco Nexus device outputs messages to terminal sessions.
By default, the switch logs system messages to a log file.
The following table describes the severity levels used in system messages. When you configure the severity
level, the system outputs messages at that level and lower.
