Chapter 3: Managing System Logs - Cisco 500 series Administration Manual

Managing System Logs
Setting System Log Settings
Cisco 500 Series Stackable Managed Switch Administration Guide
This section describes the System Log feature, which enables the switch to
generate several independent logs. Each log is a set of messages describing
system events.
The switch 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 switch 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 enable or disable logging on the Log Settings page, and select whether
to aggregate log messages.
You can select the events 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.
