• Log written to a cyclical log-file saved to the Flash memory and persists across
reboots.
In addition, you can send messages to remote SYSLOG servers in the form of SNMP traps and
SYSLOG messages.
This section covers the following sections:
• Log Settings
• Remote Logging Settings
Log Settings
You can select the events to be logged by severity level. Each log message has a severity level
marked with the first letter of the severity level concatenated with a dash (-) on each side
(except for Emergency that is indicated by the letter F). For example, the log message "%INIT-
I-InitCompleted: … " has a severity level of I, meaning Informational.
The event severity levels are listed from the highest severity to the lowest severity, as follows:
• Emergency—System is not usable.
• Alert—Action is needed.
• Critical—System is in a critical condition.
• Error—System is in error condition.
• Warning—System warning has occurred.
• Notice—System is functioning properly, but a system notice has occurred.
• Informational—Device information.
• Debug—Detailed information about an event.
You can select different severity levels for RAM and Flash logs. These logs are displayed in
the RAM Memory page and Flash Memory page, respectively.
Selecting a severity level to be stored in a log causes all of the higher severity events to be
automatically stored in the log. Lower severity events are not stored in the log.
For example, if Warning is selected, all severity levels that are Warning and higher are stored
in the log (Emergency, Alert, Critical, Error, and Warning). No events with severity level
below Warning are stored (Notice, Informational, and Debug).
