You should research and attempt to resolve the error using the Output Interpreter at this URL. 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. We do not recommend that you change the factory defaults, because this action can cause the module to malfunction. Note Writing to a module's serial EEPROM is not standard practice when the module comes from the factory, the serial EEPROM is set to the correct values. Note The messages listed in this chapter do not include the date/time stamp designation the date/time stamp designation is displayed only if the software is configured for system log messaging. 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 system sends these error messages to the console (and, optionally, to a logging server on another system). Each message is followed by an explanation and a recommended action. The highest severity level is 0, and the lowest severity level is 7. Within each facility, the messages are listed by severity levels 0 to 7. This chapter lists and describes the Cisco IOS system error messages by facility for the Catalyst 4500 series switch.
