System Message Overview

This guide describes the switch 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.

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:

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.

Table 1-1 lists the switch facility codes. These messages are described in Chapter 2, “Message and

Recovery Procedures,” in alphabetical order by facility code, with the most severe (lowest number)

errors described first.
