Chapter 35 Configuring System Message Logging
Information About System Message Logging
You can access logged system messages by using the switch command-line interface (CLI) or by saving
them to a properly configured syslog server. The switch software saves syslog messages in an internal
buffer.
You can remotely monitor system messages by viewing the logs on a syslog server or by accessing the
switch through Telnet or through the console port.
System Log Message Format
System log messages can contain up to 80 characters a nd a percent sign (%), which follows the optional
sequence number or time-stamp information, if configured. Messages appear in this form at:
seq no:timestamp: %facility-severity-MNEMONIC:description
The part of the message preceding the percent sign depends on the setting of the service
sequence-numbers, service timestamps log datetime, service timestamps log datetime [localtime]
[msec] [show-timezone], or service timestamps log uptime global configuration command.
Log Messages
You can synchronize unsolicited messages and debug privileged EXEC command output with solicited
device output and prompts for a specific console port line or virtual terminal line. You can identify the
types of messages to be output asynchronously based on the level of severity. You can also configure the
maximum number of buffers for storing asynchronous messages for the terminal after which messages
are dropped.
