Administration: System Log

Setting System Log Settings

Cisco 500 Series Stackable Managed Switch Administration Guide
This section describes the system logging, which enables the device to generate
multiple independent logs. Each log is a set of messages describing system
events.
The device generates the following local logs:
• Log sent to the console interface.
• Log written into a cyclical list of logged events in the RAM and erased when
the device reboots.
• 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:
• Setting System Log Settings
• Setting Remote Logging Settings
• Viewing Memory Logs
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.
