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
