System Error Messages Overview

---

This publication lists and describes Cisco IOS system error messages. The system software sends these error messages to the console (and, optionally, to a logging server on another system) during operation. Not all system error messages indicate problems with your system. Some are purely informational, and others may help diagnose problems with communications lines, internal hardware, or the system software.

This manual also includes error messages that appear when the system crashes.

Obtaining Technical Assistance

When the recommended action of an error message advises that you contact Cisco technical support, open a case with the Cisco Technical Assistance Center (TAC). Please see the section "Contacting TAC by Using the Cisco TAC Website" in the preface "About Cisco IOS Software."

Additional Resources

The Cisco Technical Assistance Center (TAC) has made available to all registered users an online tool, the Cisco IOS Error Message Decoder, for researching and resolving error messages.

All you have to do is copy an error message or a command output from your screen and paste it into the appropriate text fields of the tool. Within moments, the tools respond with an interpretation of your text. The Cisco IOS Error Message Decoder makes it easy for you to distinguish between error messages that are purely informational and those that alert you to potential problems. This tool provides you with an explanation of the error message, a recommended action, and links to suggested online Cisco technical support resources. For help with researching and resolving your Cisco IOS error messages, try out the new Cisco IOS Error Message Decoder tool at http://www.cisco.com/tac/newsflash/error-decoder_04302001.html.

How This Manual Is Organized

This manual contains three chapters:

•The "System Error Messages" chapter provides descriptions of error messages related to the Cisco IOS software, except for the CMCC facility. The messages are organized according to the particular system facility that produces the messages. The facility sections appear in alphabetical order, and within each facility section, messages are listed alphabetically by mnemonic. Each error message is followed by an explanation and a recommended action.

•The "CMCC System Error Messages" chapter provides descriptions of error messages related to the CMCC product family, which includes the Channel Interface Processor (CIP) and the Channel Port Adapter (CPA). The format of CMCC error messages differs from the format of other system error messages. For more information on CMCC message format, see the "CMCC System Error Messages" chapter.

•The "System Failure Error Messages" chapter provides descriptions of error messages that appear when the system image crashes.

The CMCC system error messages appear in a separate index after the index for system error messages.

For alphabetizing purposes, lowercase and uppercase letters are treated the same.

The index of error messages is alphabetized as follows:

1. Facility code

2. Mnemonic

3. Severity level

---

Note You can also view online system error messages that pertain to Cisco IOS Release 12.2-based releases. See the Cisco IOS System Error Messages for 12.2 T.

How to Read System Error Messages

System error messages begin with a percent sign (%) and are structured as follows:

%FACILITY-SUBFACILITY-SEVERITY-MNEMONIC: Message-text

FACILITY is a code consisting of two or more uppercase letters that indicate 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 lists the system facility codes.

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 2 lists the severity levels.

MNEMONIC is a code that uniquely identifies the error 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 3 lists the representations of variable fields and the type of information in them.

The following is a sample system error message:

%LINK-2-BADVCALL: Interface [chars], undefined entry point

Some error messages also indicate the card and slot reporting the error. These error messages begin with a percent sign (%) and are structured as follows:

%CARD-SEVERITY-MSG:SLOT %FACILITY-SEVERITY-MNEMONIC: Message-text

CARD is a code that describes the type of card reporting the error. VIP and FEIP are possible card types.

MSG is a mnemonic that indicates that this is a message. It is always shown as MSG.

SLOT indicates the slot number of the card reporting the error. It is shown as SLOT followed by a number (for example, SLOT5).

The prepended portion of the error message (%CARD-SEVERITY-MSG:SLOT) is not shown in the error message listings in this manual.

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.

The following sample message includes traceback information:

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