System Messages A A P P E N D I X This appendix describes the IOS system messages specific for the switch and contains these sections: • Overview, page A-1 • How to Read System Messages, page A-2 • Error Message Traceback Reports, page A-4 • Error Message and Recovery Procedures, page A-4 This switch software release is based on Cisco IOS Release 12.0. It has been enhanced to support a set of features for the Catalyst 2900 XL and Catalyst 3500 XL switches. This appendix provides system messages that have been created or changed for these switches. This appendix does not provide Cisco IOS Release 12.0 commands and information already documented in the Cisco IOS Release 12.0 documentation on Cisco.com. Note From CMS (Reports > System Messages), you can display the system messages of the Catalyst 2900 XL and Catalyst 3500 XL switches when they are in a cluster where the command switch is a Catalyst 2950 switch running Release 12.1(6)EA2 or later or a Catalyst 3550 switch running Release 12.1(8)EA1 or later. The System Messages option is not available from the Catalyst 2900 XL and Catalyst 3500 XL switches. Overview The system software sends IOS system messages to the console (and, optionally, to a logging server on another system) during operation. Not all system messages mean problems with your system. Some messages are purely informational, and others can help diagnose problems with communications lines, internal hardware, or the system software. Each message includes the message itself, an explanation of the problem or condition, and, if available, a recommended course of action. 78-6511-08 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide A-1
