APPENDIX
B
Catalyst 3550 Switch Debug Commands
This appendix describes only the Catalyst 3550-specific debug privileged EXEC commands. These
commands are helpful in diagnosing and resolving internetworking problems and should be enabled only
under the guidance of Cisco technical support staff.
Caution Because debugging output is assigned high priority in the CPU process, it can render the system
unusable. For this reason, use the debug commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco technical support staff. It is best to use the debug commands during
periods of lower network traffic and fewer users. Debugging during these periods decreases the
likelihood that increased debug command processing overhead will affect system use.
