System Message Overview

This guide describes the switch-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.
For information about Cisco IOS system messages that are not specific to this switch, see the Cisco IOS
Software System Messages for Cisco IOS Release 12.2 on www.cisco.com.

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:
