Cisco ME 3400 Ethernet Access Switch
Debug Commands


Please confirm whether or not the This appendix describes the debug privileged EXEC commands that have been created or changed for use with the Cisco ME 3400 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.

When selecting the file read operation, Operation 1 reads the file header, which contains the header verification word and the file version number. Operation 2 reads the main body of the file, which contains most of the domain and VLAN information. Operation 3 reads type length version (TLV) descriptor structures. Operation 4 reads TLV data.
