What Are the Severity Levels? For each local or remote log file, you can specify the severity of the messages to log. Each severity level is identified by a name and a number. Table 10-1 provides information about the severity levels. Table 10-1. Log Message Severity Severity Keyword Severity Level Description emergencies 0 The switch is unusable. alerts 1 Action must be taken immediately. critical 2 The switch is experiencing critical conditions. errors 3 The switch is experiencing error conditions. warnings 4 The switch is experiencing warning conditions. notification 5 The switch is experiencing normal but significant conditions. informational 6 The switch is providing non-critical information. debugging 7 The switch is providing debug-level information. When you specify the severity level, messages with that severity level and higher are sent to the log file. For example, if you specify the severity level as critical, messages with a severity level of alert and emergency are also logged. When you specify the severity level in a CLI command, you can use the keyword or the numerical level. What Are the System Startup and Operation Logs? Two types of log files exist in flash (persistent) memory: • The first log type is the system startup log. The system startup log stores the first 32 messages received after system reboot. The log file stops when it is full. • The second log type is the system operation log. The system operation log stores the last 1000 messages received during system operation. The oldest messages are overwritten when the file is full. A message is only logged in one file. On system startup, if the Log file is enabled, the startup log stores messages up to its limit. Then the operation log begins to store the messages. Monitoring and Logging System Information 237
