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. Table 1-1 lists Catalyst 3750-specific 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.

SEVERITY is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower the number, the more serious the situation. Table 1-2 lists the message severity levels.

Table 1-2 Message Severity Levels 

Severity Level
Description

0 - emergency

System is unusable.

1 - alert

Immediate action required.

2 - critical

Critical condition.

3 - error

Error condition.

4 - warning

Warning condition.

5 - notification

Normal but significant condition.

6 - informational

Informational message only.

7 - debugging

Message that appears during debugging only.


MNEMONIC is a code that uniquely identifies the message.

Message-text is a text string describing the condition. This portion of the message sometimes contains detailed information about the event, including terminal port numbers, network addresses, or addresses that correspond to locations in the system memory address space. Because the information in these variable fields changes from message to message, it is represented here by short strings enclosed in square brackets ([ ]). A decimal number, for example, is represented as [dec]. Table 1-3 lists the variable fields in messages.

Table 1-3 Representation of Variable Fields in Messages 

Representation
Type of Information

[dec]

Decimal integer

[char]

Single character

[chars]

Character string

[enet]

Ethernet address (for example, 0000.FEED.00C0)

[hex]

Hexadecimal integer

[inet]

Internet address


All syslog messages generated by a switch other than the master switch are displayed ending with (Switch-x) where Switch-x is the number of the stack member generating the message. Syslog messages generated by the master switch are displayed with no hostname string.

This example shows a partial switch system message for a stack master and a stack member switch (hostname Switch-2):

Error Message Traceback Reports

Some messages describe internal errors and contain traceback information. This information is very important and should be included when you report a problem to your technical support representative.

This message example includes traceback information:

-Process= "Exec", level= 0, pid= 17
-Traceback= 1A82 1AB4 6378 A072 1054 1860 

Some system messages ask you to copy the error messages and take further action. These online tools also provide more information about system error messages.

Output Interpreter

The Output Interpreter provides additional information and suggested fixes based on the output of many CLI commands, such as the the show tech-support privileged EXEC command. You can access the Output Interpreter at this URL:

Bug Toolkit

The Bug Toolkit provides information on open and closed caveats, and allows you to search for all known bugs in a specific Cisco IOS Release. You can access the Bug Toolkit at this URL:
