Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco ME 3400E Ethernet Access Switch
Debug Commands

This appendix describes the debug privileged EXEC commands that have been created or changed for use with the Cisco ME 3400E Ethernet Access 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.
