IE 3000 Switch Debug Commands
This appendix describes the debug privileged EXEC commands that have been created or changed for use with the IE 3000 switch. 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.
debug authentication
Use the debug authentication privileged EXEC command to enable debugging of the authentication settings on an interface. Use the no form of this command to disable debugging.
