System Message Overview
This guide describes the Catalyst 3750, 3560, 3550, 2975, 2970, 2960, and 2960-S-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 mean problems with your system. Some messages are informational, and others can help diagnose problems with communications lines, internal hardware, or the system software.
Note For information about system messages that are not Catalyst 3750, 3560, 3550, 2975, 2970, 2960, or 2960-S platform-specific, see the Cisco IOS Software System Messages for Cisco IOS Release 12.2S 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 appear in this format:
seq no:timestamp: %facility-severity-MNEMONIC:description (hostname-n) (only Catalyst 3750, 2975, and 2960-S switches)
seq no:timestamp: %facility-severity-MNEMONIC:description (switches other than Catalyst 3750, 2975, and 2960-S switches)
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 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, 3560, 3550, 2975, 2970, 2960, and 2960-S-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
|
|
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 Variable Fields
|
|
[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 Catalyst 3750, 2975, and 2960-S 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 on a switch other than a Catalyst 3750, 2975, and 2960-S switch:

This example shows a partial switch system message for a stack master and a stack member switch (hostname Switch-2) in a Catalyst 3750 switch stack, a Catalyst 2975 switch stack, or a Catalyst 2960-S switch stack:

Error Message Traceback Reports
Some messages describe internal errors and contain traceback information. Include this information 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 resolutions based on the output of many CLI commands, such as the show tech-support privileged EXEC command.

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.
