Configuring and Managing the System Log

System logs provide information about system events that you can use to monitor and troubleshoot
MSS. Event messages for the switch and its attached access points can be stored or sent to the
following destinations:
• Stored in a local buffer on the switch
• Displayed on the switch console port
• Displayed in an active Telnet session
• Sent to one or more syslog servers, as specified in RFC 3164
The system log is a file in which the newest record replaces the oldest. These entries are preserved in
nonvolatile memory through system reboots.
Each log message contains the following components:
Field
Facility
Date
Severity
Tag
Message
A logging destination is the location to which logged event messages are sent for storage or display. By
default, only session logging is disabled. You can enable or disable logging to each destination and filter
the messages by the severity of the logged event or condition.
System events and conditions at different severity levels can be logged to multiple destinations. By
default, events at the error level and higher are posted to the console and to the log buffer. Debug output
is logged to the trace buffer by default. The table on the next page summarizes the destinations and
defaults for system log messages.
