Chapter 2 Messages And Recovery Procedures - Cisco Catalyst 4500 Series System Message Manual

Messages and Recovery Procedures
This chapter lists and describes the Cisco IOS system error messages by facility for the Catalyst 4500
series switch. Within each facility, the messages are listed by severity levels 0 to 7. The highest severity
level is 0, and the lowest severity level is 7. Each message is followed by an explanation and a
recommended action.
The system sends these error messages to the console (and, optionally, to a logging server on another
system). Not all system error messages indicate problems with your system; some messages are purely
informational, while other messages help diagnose problems with communication lines, internal
hardware, or the system software.
The messages listed in this chapter do not include the date/time stamp designation; the date/time stamp
Note
designation is displayed only if the software is configured for system log messaging.
Writing to a module's serial EEPROM is not standard practice; when the module comes from the factory,
Note
the serial EEPROM is set to the correct values. We do not recommend that you change the factory
defaults, because this action can cause the module to malfunction.
If the explanation that is provided for a given command does not sufficiently explain your problem and
no recommended action is given, copy the error message exactly as it appears on the console or in the
system log.
You should research and attempt to resolve the error using the Output Interpreter at this URL:
https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl.
You can also enter the show tech-support command to gather additional information about the error. If
the error message text, information from the Output Interpreter, or output from the show tech-support
command do not help you solve the problem, contact your technical support representative and provide
the representative with the information that you have gathered. For detailed information on how to
contact your technical support representative, see the
