How to Read System Messages

The system software sends system error messages to the console (and, optionally, to a logging server on another system) during operation and when the system crashes. 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.

The messages are organized according to the particular system category that produces the messages. The category sections appear in alphabetical order, and within each category section, messages are listed alphabetically by group code. Each message is followed by an explanation and a recommended action.

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

System Error Message Format

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

%CATEGORY-GROUP-SEVERITY-MNEMONIC: Message-text

CATEGORY is a code consisting of two or more uppercase letters that indicate the category to which the message refers. Table 1 lists the system category codes for the Cisco CRS-1 Cisco XR 12000 Series Router, and Cisco ASR 9000 Series Router.

GROUP is a code consisting of two or more uppercase letters that indicate the group to which the message refers. A group can be a hardware device, a protocol, or a module of the system software.

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:

%ACL-IP_ACL_PARSE-2-ALLOC Unable to allocate memory for [chars] 
Table 1  Category Codes

Code

Description of Category

HA

All High Availability (HA) related messages.

INSTALL

All Installation related messages.

IP

All Internet Protocol (IP) related messages.

L1

All Layer 1 (L1) related messages.

L2

All Layer 2 (L2) related messages, for instance ethernet drivers, PoS, SONET, PLIMS, and so forth.

L3

All Layer 3 (L3) related messages.

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

Informational message only

7 - debugging

Appears during debugging only

Message severity levels correspond to the keywords assigned by the logging console and logging monitor global configuration commands that define where and at what level these messages appear. In general, the default is to log messages from level 0 (emergencies) to level 7 (debugging). However, the default level varies by platform.

Level 4 severity messages should be monitored and if the warning affects your router, investigate and take the necessary action. Levels 5 to 7 are only informational and TAC should not be contacted.

For more information, see the system configuration chapter and descriptions of the logging console and logging monitor commands in the appropriate Cisco IOS configuration guide and command reference publications.

Table 3  Representation of Variable Fields in Messages

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

Obtaining Technical Assistance

When the recommended action of an error message advises that you contact Cisco technical support, submit a Cisco Technical Assistance Center (TAC) service request.

Before contacting TAC, you should perform the following tasks to assist TAC in troubleshooting your service request:

  • Capture system logs for the past two days.
  • Execute the show tech-support command.
  • Obtain crash dumps from the router.
