Information About Configuring System Message Logs
You can remotely monitor system messages by viewing the logs on a syslog server or by accessing the switch
through Telnet, through the console port, or through the Ethernet management port. In a switch stack, all stack
member consoles provide the same console output.
The syslog format is compatible with 4.3 BSD UNIX.
Note
System Log Message Format
System log messages can contain up to 80 characters and a percent sign (%), which follows the optional
sequence number or time-stamp information, if configured. Depending on the switch, messages appear in one
of these formats:
• seq no:timestamp: %facility-severity-MNEMONIC:description (hostname-n)
• seq no:timestamp: %facility-severity-MNEMONIC:description
The part of the message preceding the percent sign depends on the setting of these global configuration
commands:
• service sequence-numbers
• service timestamps log datetime
• service timestamps log datetime [localtime] [msec] [show-timezone]
• service timestamps log uptime
