System Message Overview
This guide describes the Cisco IE 3000 switch-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 Cisco IE 3000 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 appear in this format:
seq no:timestamp: %facility-severity-MNEMONIC:description
By default, a switch sends the output from system messages to a logging process.
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 the Cisco IE 3000 switch-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.
•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.
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.
