System Error Messages Overview

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, while 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.

How This Manual Is Organized

This manual contains three main chapters.

For alphabetizing purposes, lowercase and uppercase letters are treated the same and underscores (  _  ) are ignored.

The index of error messages is alphabetized as follows:

    1. Facility code

    2. Mnemonic

    3. Severity level

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 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.)


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

Table 2: Error Message Severity Levels
Level Description

0 - emergency

System unusable

1 - alert

Immediate action needed

2 - critical

Critical condition

3 - error

Error condition

4 - warning

Warning condition

5 - notification

Normal, but significant, condition

6 - informational

7 - debugging

Appears during debugging only

Error message severity levels correspond to the keywords assigned by the logging global configuration commands that define where and at what level these messages appear. The default is to log messages to the console at the debugging level (7). For more information, see the system configuration chapter and descriptions of the logging command in the appropriate Cisco IOS configuration guide and command reference publications.

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:

-Traceback= 1A82 1AB4 6378 A072 1054 1860
