System Message Overview
This guide describes the Catalyst 3750-specific system messages. During operation, the system software
sends these messages to the console (and, optionally, to a logging server on another system). Not all
system messages indicate problems with your system. Some messages are purely informational, whereas
others can help diagnose problems with communications lines, internal hardware, or the system
software. This guide also includes error messages that appear when the system fails.
Note
For information about system messages that are not Catalyst 3750 platform-specific, see the Cisco IOS
Software System Messages for Cisco IOS Release 12.2S.

How to Read System Messages
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. Messages are displayed in this format:
seq no:timestamp: %facility-severity-MNEMONIC:description (hostname-n)
By default, a switch sends the output from system messages to a logging process. In a switch stack, stack
members append their hostnames to the output from system messages and redirect the output to the
logging process on the stack master.
Each system message begins with a percent sign (%) and is structured as follows:
%FACILITY-SEVERITY-MNEMONIC: Message-text

FACILITY is a code consisting of two or more uppercase letters that show the facility to which the
message refers. A facility can be a hardware device, a protocol, or a module of the system software.
